Iron ore · High grade
High Grade Iron Ore Supplier
A high-grade label is a commercial descriptor, not a complete specification. Require the analytical Fe method and tolerance together with SiO2, Al2O3, P, S and other contract-relevant chemistry, moisture, sizing, sampling basis, origin/document needs and delivery terms.

Fit, alternatives and selection logic
When a high-grade label helps — and when it does not
Unlike a numeric band, “high grade” has no agreed definition. It is a relative descriptor, and what one supplier calls high grade another may not. Until the Fe figure, its basis and its tolerance are stated, the label tells you nothing you can contract against. Use the three states below to see where your enquiry actually sits.
The label is a useful shorthand when your specification is already expressed in lot-specific terms — a stated Fe figure with its method and tolerance, impurity limits, moisture basis, size distribution and a named process route. In this state “high grade” is a conversational short-hand for a schedule you have already built. The schedule does the deciding; the words do not.
- A definite Fe figure with its method and tolerance
- Impurity limits set from your process, not assumed
- Size distribution and moisture basis tied to your receiving step
This is where nearly every high-grade enquiry actually lands. There is no number to test, so the label cannot be checked at all until the offer states a definite Fe figure, the analytical method behind it, the tolerance band and the sampling basis. Two offers both described as high grade may be measured against different methods on differently drawn samples — and may sit several points apart on the Fe scale.
- No definite Fe figure stated, only the descriptor
- Impurity limits left to the supplier to assume
- Sampling basis and analytical method not named
The term is the wrong basis for a decision whenever acceptance is defined by a field it cannot express — a contractual minimum Fe figure, a maximum phosphorus or alumina limit, a reduction-behaviour requirement, or a sizing tied to one process. A relative descriptor cannot be enforced, so in these cases the qualifying field is the one your contract names rather than anything the label implies.
- Acceptance driven by a definite figure or impurity limit
- Process performance (reduction, agglomeration) is the driver
- Sizing or moisture specified against one downstream route
On comparing grades. A high-grade description usually implies a figure somewhere in the upper commercial bands, but it commits to none of them. The named bands — 62%, 63.5% and 65% Fe — are not interchangeable specifications either: each carries its own typical impurity profile, product forms and often its own penalty structure, so a higher figure does not automatically mean a better fit for your route. Ask which band the offer actually sits in, then compare the full acceptance schedule.
Registered alternatives, grouped by the open question
These are the registered routes that sit closest to a high-grade enquiry. Each is a different decision, not a substitute — pick the group that matches what is still unresolved in your specification.
Where the mineralogy or the product form itself is the open question.
- hematite iron ore supplier The bounded mineralogical comparison — Fe₂O₃, typically shipped as direct shipping ore. Mineralogy is a different axis from grade, so compare on the field that actually differs.
- magnetite iron ore supplier Fe₃O₄, typically beneficiated into a concentrate before use, which changes mass yield and the commercial basis at the same nominal grade.
Where the sizing or preparation state rather than the mineralogy is the deciding field.
- iron ore concentrate supplier A beneficiated fine product where the assay basis and moisture determination decide comparability more than the headline figure.
- iron ore fines supplier Fine material fed to sintering or blended before agglomeration, where blend chemistry matters more than any single offer's grade.
- iron ore pellets supplier An already-agglomerated product with defined physical properties — a different decision from buying ore at the same grade.
Where a stated Fe band rather than a mineralogical name is what your process actually constrains.
- 63.5 fe iron ore supplier The nearest adjacent band below 65 — the difference is only meaningful once assay method, tolerance and impurity limits are stated for both.
- 62 fe iron ore supplier The lower adjacent band, where a wider gap in the Fe figure does not license a like-for-like substitution across your acceptance schedule.

High-Grade Completeness Checker
Enter what your enquiry actually says. The checker reports whether the evidence behind it is complete enough for two offers to be compared — it does not rank quality, score suppliers or claim availability.
Your offer or requirement
Fields left blank are reported as unresolved rather than filled in. Nothing is defaulted on your behalf.
Not yet comparable across offers
A grade label states a commercial band. Until the analytical Fe method, the tolerance and the sampling basis are stated — and the label is not being used as a stand-in for a full acceptance schedule — any comparison would rest on an assumption about the material rather than on evidence.
Evidence checklist
- Fe basis stated (wet or dry) — not yet satisfiedNo Fe basis given — this alone blocks a comparable result.
- Fe value present — not yet satisfiedThe Fe figure itself must be stated, not merely its basis.
- Buyer chemistry limits set by you — not yet satisfiedSilica, alumina, phosphorus and sulphur limits come from your process. This tool supplies no defaults and no tolerances.
- Moisture basis stated — not yet satisfiedWet and dry tonnage only reconcile when the basis is named.
- Moisture value with unit — not yet satisfiedThe figure must carry the basis it is reported on.
- Size distribution stated — not yet satisfiedAgglomeration and reduction behaviour both depend on it.
- Size determination method named — not yet satisfiedA range without a screening or laser method cannot be reproduced at receipt.
- Sampling and inspection basis named — not yet satisfiedHow the lot is sampled, and who witnesses it, determines whether the assay is accepted at the hold point.
- Process route identified — not yet satisfiedThe intended route decides which physical and metallurgical tests are relevant.
- Commercial and destination inputs stated — not yet satisfiedQuantity, destination and Incoterm are what make two offers comparable rather than merely descriptive.
- Documents requested rather than assumed — not yet satisfiedCOA, moisture, size and inspection documents are each a separate request.
Missing inputs (12)
- Fe target with its wet or dry basis — the single field that decides whether two offers are comparable.
- Buyer-defined chemistry limits for SiO₂, Al₂O₃, P and S. Your plant sets these; this tool supplies no defaults.
- Moisture basis — determines how wet and dry tonnage reconcile and how price per ton is compared.
- Size distribution — governs how the material behaves in your receiving process.
- Size determination method — without it the distribution cannot be reproduced at receipt.
- Sampling and inspection basis — how the lot sample is drawn and who witnesses it.
- Intended process route — blast furnace, direct reduction, pelletizing or steelmaking. It determines which physical and metallurgical tests matter.
- Product form — confirm the enquiry is for the form you actually need.
- Quantity and cadence — the basis the quotation will be compared on.
- Destination port or place — determines the delivery leg and document set.
- Incoterm and named place.
- Required documents — COA, moisture, size and inspection reports are requested, not assumed.

Standards, grades and service conditions
The fields an Fe grade figure does not carry
A grade figure fixes one field and leaves the rest open. Each parameter below is established by a method applied to a sample, and each one changes what two offers claiming the same grade actually mean when compared.
| Parameter | Buyer requirement | Unit / basis | Verification method | Tolerance source | Applicability | Action |
|---|---|---|---|---|---|---|
| Fe content | Your target with the basis stated | % — dry or wet, declared | Assay by the method your contract names | Your acceptance limit, not ours | Applies to the lot as sampled — the grade label does not set it | State basis on the RFQ |
| SiO2 | Your process limit | % — dry basis as tested | Assay per the agreed method | Set by your process; gangue affects slag volume and yield | Gangue content is independent of the dominant iron mineral | Enter the limit explicitly |
| Al2O3 | Your process limit | % — dry basis as tested | Assay per the agreed method | Set by your process; affects slag viscosity | Not implied by the grade figure | Enter the limit explicitly |
| P (phosphorus) | Your maximum limit | % — dry basis as tested | Assay per the agreed method | Set by your steelmaking route | Carries through to hot metal quality; a critical constraint on some routes | Enter the maximum explicitly |
| S (sulphur) | Your maximum limit | % — dry basis as tested | Assay per the agreed method | Set by your steelmaking route | Route-dependent; more critical on direct reduction than on some sinter routes | Enter the maximum explicitly |
| Moisture | The basis quantities are traded on | % — as received or as determined | Determination per a named moisture method | Contract wording defines the adjustment | Determines wet/dry reconciliation and the price basis | State basis plus method |
| LOI | Relevant where your route constrains it | % — determination basis stated | Determination per the named method | Project or plant requirement | Where the process is sensitive to loss on ignition; some hydrated forms carry more | State requirement or mark unresolved |
| Size distribution | The range your route accepts | mm with stated cut points | Screening or laser method, named | Agreed against your receiving process | A coarse label says nothing about the actual distribution | State distribution plus method |
| Sampling | How the lot sample is drawn and witnessed | Method and sampling frequency | Standards-based lot sampling regime | Purchaser and supplier agree the basis | Determines whether the assay is accepted at the hold point | Name the sampling basis |
Evidence warning. No numeric value, tolerance or limit is published on this page for any parameter above. Ranges depend on the deposit, the product form, your process and the grade you specify, and each belongs to be stated and verified in your enquiry. Where a figure is required, request it with its unit, method and basis — a mineralogical name supplies none of them.
Physical and metallurgical parameters the process tests
Chemistry describes what the material contains. These parameters describe how it behaves in a given route, and between two offers at the same nominal grade, these are often what separates them. Each row is a request for the figure and the method behind it.
| Parameter | Buyer implication | Unit / basis | Verification method | Applicability / limitation | RFQ field or next action |
|---|---|---|---|---|---|
| Reducibility | Indicates how the material performs in a reduction step rather than in the furnace burden alone. | Reported as a rate or degree — basis stated | Determination per the agreed metallurgical test | Applicable where the route includes direct reduction; not a sintering criterion and rarely the deciding field on a sinter route | State whether your route requires it at all |
| Bulk density | Feeds handling, stockpile volume and vessel stowage planning. | t/m³ — as shipped, moisture stated | Determination per a named bulk density method | Depends on moisture and compaction at the time of measurement | Request the figure and its moisture condition |
| Loss on ignition (LOI) | Relevant where the process is sensitive to mass lost on heating. | % — determination basis stated | Determination per the named method | Project or plant specific; not an acceptance limit unless your contract says so | State the requirement or mark it unresolved |
| Gangue mineralogy | Explains why two offers with the same SiO2 figure can behave differently in the furnace. | Qualitative or %, with the reporting basis | Mineralogical examination or a named test | Where a petrographic or mineralogical basis is agreed; otherwise descriptive only | Request only if your process is sensitive to it |
| Tumbler / abrasion index | Signals degradation during handling and transfer between load port and plant. | Index value — test method named | Determination per the named physical test | Applies to lump or DSO material subject to repeated handling; of limited use on a fine product | Request where handling degradation is a known issue |
| Sinter or pellet test | Shows how the material performs in the specific agglomeration step rather than in general. | Test-specific index — conditions stated | Determination per the agreed agglomeration test | Only meaningful where the route actually includes that agglomeration step | State the agglomeration route before requesting it |
Standards that carry the verification
Two standards do most of the work in a grade enquiry: one for how the lot is sampled, one for how iron content is determined. Naming both in the contract is what makes an assay reproducible between the offer and your receipt.
Applicability boundary: these routes explain what each standard covers and where its scope ends. Neither substitutes for the edition your contract cites, and neither implies that any material meets them.
Quality, testing and documentation
What each document verifies — and what it does not
Documents are requested, not assumed. Each one below answers a distinct question, and none of them substitutes for your contract's acceptance basis.
| Requested evidence | What it verifies | Who supplies / verifies | When required | Quotation / project dependency |
|---|---|---|---|---|
| Certificate of analysis (COA), per lot | The chemical composition the lot is accepted against — Fe plus the impurity limits your process set. | Issued against the agreed assay method; the issuing laboratory is confirmed per enquiry. | At the enquiry stage, as the basis for comparison. | Which laboratory, and whether your contract accepts its scope, remains a project decision. |
| Moisture determination report | The figure behind the wet/dry tonnage reconciliation and the commercial basis. | Issued per a named moisture method; confirm it travels with the lot. | Before quantity and price are compared. | The method and its acceptance depend on your contract wording. |
| Size distribution report | Whether the material suits the process step it was specified for. | Issued per the agreed size method; confirm the cut points reported. | Before the material is committed to a route. | Cut points and tolerances are yours to set, not to assume. |
| Sampling and inspection record | Whether the assay is defensible at your hold point. | Issued against the agreed sampling standard and any appointed inspection party. | Agreed at enquiry, not at the port. | Whether a third-party inspection party is appointed is a project decision. |
| Physical / metallurgical test results | How the material behaves in your specific route, where your route requires it. | Determined per the agreed test method. | Only where the intended route makes the test relevant. | The test set depends entirely on the process route you confirm. |
| Origin and shipping documents | Customs clearance and, where applicable, origin requirements. | Issued per shipment. | Before dispatch. | Only relevant if your project or jurisdiction imposes an origin requirement. |
Availability and documentation matrix
Availability is not a property of the material — it is a statement about a specific enquiry at a specific time. This matrix sets out what would have to be confirmed before any availability statement could be made.
| Item to confirm | Buyer implication | Applicability / limitation | Verification / source requirement | RFQ field or next action |
|---|---|---|---|---|
| Quantity available for the enquiry | Determines whether the requirement can be structured as a single lot or a repeating programme. | A quantity answer is only meaningful against a stated specification, destination and period. | Confirm per enquiry. No standing quantity is published on this page. | State quantity, cadence and required delivery window |
| Delivery window | Sets whether the requirement plans against production and shipping, or needs another arrangement. | Requires the destination and the Incoterm to be named before any window is meaningful. | Confirm per enquiry in writing against the stated Incoterm. | State the required date or schedule in the RFQ |
| Loading and packing form | Changes handling cost, stowage planning and the documents that accompany the movement. | Depends on the vessel or container arrangement, which follows the destination and quantity. | Confirm per enquiry against the agreed loading form. | State the required loading or packing form |
| Product form actually offered | Determines whether the offer is comparable at all — lump, fines, concentrate and pellet feed are different decisions. | A mineralogical description does not establish form or sizing. | Confirm against the offer documentation per enquiry. | State the form your process requires |
| Sampling regime and witnessing party | Establishes whether the assay will be accepted at your hold point. | Applies to the lot as sampled under the agreed regime, not to the source generally. | Confirmed against the sampling standard your contract names. | Name the sampling basis and any witnessing party |
| Document set issued per lot | Determines whether your hold point is a check or a negotiation. | Each document covers the sampled lot only — none is a general quality guarantee. | Confirmed per enquiry against the requested set. | Request each document explicitly in the RFQ |
| Origin documentation requirement | Needed for customs clearance and, where applicable, origin requirements. | Only relevant if your project or jurisdiction imposes an origin requirement. | Issued per shipment; confirm the set required at your destination. | State your destination and any origin requirement |
This page publishes no stock position, availability statement, lead time, shipping schedule, mine or mill ownership, or certification claim for any material. Every row above is a question to be confirmed per enquiry.
Evidence gates before the lot is traded
- 1Mineralogy gateThe dominant iron mineral is recorded as context. It is not accepted as a substitute for a stated Fe basis.
- 2Basis gateFe, moisture and size figures each carry a stated basis and method before any comparison is made.
- 3Sampling gateThe sampling regime and any witnessing party are agreed at the enquiry stage, not at the port.
- 4Limit gateChemistry limits come from your process and each is tied to the method that verifies it.
- 5Route gateThe intended process route is stated, because it decides which physical and metallurgical tests apply.
- 6Document gateEach requested document is named in the enquiry and confirmed against what the route will actually issue.
Certification limits: this section describes document types and their verification roles. It makes no claim about which certificates Noor Deira Steel holds, which party issued any prior report, or what any future lot will be certified to.
Application and industry decision paths
Where the process route changes what you must specify
A grade band narrows the iron content but leaves the route-specific requirement untouched. These are the registered process and sector routes, and what each one shifts in your acceptance criteria.
Blast furnace burden
- Operating condition
- Burden components where chemistry, gangue and physical form together determine furnace performance.
- What shifts in the specification
- Gangue content and its effect on slag volume and coke rate become procurement-relevant.
- Why routes are not interchangeable
- The furnace accepts a prepared burden, so the upstream agglomeration step defines much of the requirement.
Direct reduction (DRI)
- Operating condition
- Reduction of ore to metallic iron without a melting step, where the ore's behaviour in reduction governs.
- What shifts in the specification
- Reducibility, gangue and low residual elements become governing rather than incidental.
- Why routes are not interchangeable
- A requirement set for a blast furnace burden is not automatically suitable for a direct reduction route.
Steel production
- Operating condition
- Feed into a steelmaking chain where residual elements and consistency affect the final product.
- What shifts in the specification
- Phosphorus, sulphur and trace elements come under closer acceptance limits.
- Why routes are not interchangeable
- Steelmaking acceptance is set by the finished product specification, not by the ore description.
Integrated mills
- Operating condition
- Sites operating their own agglomeration and ironmaking chain with internal specifications.
- What shifts in the specification
- The plant's own internal spec governs, and your enquiry has to reflect it rather than a general grade.
- Why routes are not interchangeable
- An integrated mill sets its own acceptance basis; a trader buying to re-sell may not.
Pellet plants
- Operating condition
- Plants converting a fine concentrate feed into pellets for external sale or internal use.
- What shifts in the specification
- Feed consistency between shipments matters as much as the absolute values, because the pellet grade depends on the concentrate grade going in.
- Why routes are not interchangeable
- Variance across lots is a procurement issue here, not just the mean figure, and a concentrate feed at a given Fe grade is specified differently from a lump ore at the same grade.
GCC markets and destination planning
Destination changes the documents and the delivery, not the mineralogy
A resolved basis travels the same way wherever it ships. What changes by destination is the documentation set, the delivery location, the customs route and the delivery term the quotation must reflect.
United Arab EmiratesEnquiries landing at Jebel Ali, Khalifa Port or a free-zone consignee need the delivery place named before the Incoterm means anything. State the port or free zone, and whether the receiving plant or the trader takes the customs entry.iron ore supplier UAE 
Saudi ArabiaShipments into Dammam or Jeddah typically move on to inland industrial cities, so the quotation has to reach the inland place rather than stop at the port. Say whether the rail or road leg sits inside your requirement, and which conformity documents your consignee needs.iron ore supplier Saudi Arabia 
QatarHamad Port consignments are usually cleared against a document set agreed in advance. Name the consignee, the delivery place and whether the receiving plant requires the assay and moisture documents before discharge rather than after.iron ore supplier Qatar 
KuwaitShuwaikh and Shuaiba movements are short-sea legs, so the packing or loading form affects handling more than the voyage. State whether the requirement is containerised or breakbulk, because it changes the documents and the discharge arrangement.iron ore supplier Kuwait 
BahrainKhalifa Bin Salman Port deliveries often connect to a mainland industrial consumer, so the delivery place may not be the port itself. Name the final place and the Incoterm that reaches it, and confirm whether the entry is taken by your consignee or a broker.iron ore supplier Bahrain 
OmanSohar and Duqm consignments sit close to industrial zones where the receiving site may take delivery directly. State the port or zone, the delivery term that reaches it, and whether origin documentation is a requirement for your end use.iron ore supplier Oman These are destination planning routes. They describe the logistics and documentation inputs each destination changes. They make no claim that Noor Deira Steel holds stock, a branch, a warehouse or a port presence in any market listed.
Commercial, logistics and availability inputs
What the quotation rests on — and what stays open
A quotation is only comparable when the inputs behind it are stated. Each row below names what an input changes and what remains unknown until it is confirmed.
| Quotation input | What it changes | What remains unknown until confirmed |
|---|---|---|
| Fe basis and chemistry limits | Which material is being priced at all, and against which acceptance limits. | Nothing, once stated. Left open, it is the largest source of non-comparable offers. |
| Moisture basis and method | Whether quantities and price adjustments are on a wet or dry basis. | The effective dry tonnage, and therefore the delivered cost per dry tonne. |
| Size distribution and method | Whether the material suits the receiving plant's process step. | Process suitability until the distribution and its method are known. |
| Product form | Whether the offer is lump, fines, concentrate or pellet feed — different decisions entirely. | Comparability itself, until the form is confirmed against your requirement. |
| Quantity and cadence | Whether the requirement is a single lot or a repeating programme. | The commercial structure and the shipment planning basis. |
| Destination port and Incoterm | Which carriage legs, duties and charges sit inside the quoted figure. | The delivered cost until the place and the term are named. |
| Loading and packing form | How the material is presented at load port and discharged at destination. | Handling cost and the documents that accompany the movement. |
| Document set | Which evidence the lot carries and what the buyer's hold point accepts. | Whether the evidence satisfies the contract until the set is named. |
| Delivery window | Whether the requirement plans against production and shipping, or needs another arrangement. | Any statement of lead time or schedule — this page makes none. |
What this page does not claim
- No price, benchmark, discount or premium is published.
- No stock position or availability is claimed for any material.
- No lead time, loading rate or shipping schedule is stated.
- No mine, mill, source origin or ownership is claimed.
- No certification, lab accreditation or project approval is claimed.
- No served-market, branch, warehouse or port presence is claimed.

Expert insight
What evidence most directly changes the procurement decision here?
On a grade enquiry, the item that most often decides whether two offers are comparable is not the Fe figure itself — both will quote one — but whether the analytical method and the sampling basis behind those figures are the same.
Verify-first checklist
Work through these before comparing two offers at the same nominal grade. Each is a question the offer has to answer, not one the supplier can infer for you.
- 1Sample before you compareA chemistry value is only decision-grade if the lot was sampled and prepared representatively. Ask for the sampling basis before you treat any figure as comparable.
- 2Separate mineralogy from gradeA relative descriptor such as “high grade” states no definite figure at all. Even a numeric grade label states a commercial band, not a measured result. The measured figure, the method that produced it and the tolerance around it are separate fields your contract has to set.
- 3Name the methods behind every figureFe, moisture, size and any physical test are each produced by a method. The method is what makes the number reproducible at your receipt.
- 4Set chemistry limits from your processSilica, alumina, phosphorus and sulphur limits belong to your plant. They are not defaults and should not be assumed.
- 5Confirm the edition your contract citesStandard editions change. Verify the edition named in your contract rather than the one quoted in general conversation.
- 6Match the tests to the routeReducibility, tumbler index and agglomeration tests are only relevant if your route actually includes that step.
Buyer implication. A certificate value is only as useful as the sampling basis behind it. The RFQ should state the lot, the sampling method, the test method and the acceptance basis — rather than asking only for an Fe number.

- ISO 2597-1:2006 — Iron ores — Determination of total iron content — Part 1
- Direct source URL
- iso.org — ISO 2597-1:2006
- Method
- Use the ISO scope to distinguish a measured total-iron result from a commercial grade label, and to require the analytical method and sample basis alongside any Fe percentage.
- Information date
- 2026-09-22
- Scope
- Titrimetric determination of total iron content in natural iron ores, concentrates and agglomerates within the method's stated range.
Limitations
- The method measures total iron only; it does not establish impurity limits, size distribution, moisture, physical strength or metallurgical performance.
- A commercial label such as 62% Fe or 65% Fe is not a complete purchase specification, and contract tolerances remain buyer-seller specific.
- This is an evidence-backed decision aid, not a named-person profile, and not a substitute for the standard itself.
Evidence-led buyer advantages
What we do about the ways a grade offer misleads
Each item starts from a real concern on a grade enquiry, states the practice that addresses it, and ends at the outcome it produces. None rests on a claim about stock, origin or price that this page cannot substantiate.
- Buyer concern
- A grade label mistaken for a specification
- What we do
- We treat the grade figure as one field, not as the specification, and ask for the assay method and tolerance alongside it before comparing anything.
- Procurement outcome
- Offers are compared on a stated figure rather than on a descriptive name.
- Buyer concern
- Chemistry quoted without a sampling basis
- What we do
- A certificate value is only as good as the sample behind it, so we ask for the sampling and preparation basis alongside the assay.
- Procurement outcome
- The result is defensible at your hold point rather than arguable at it.
- Buyer concern
- Moisture quoted without a method
- What we do
- Moisture without a determination method is flagged as a conflict, because two offers quoting the same figure under different methods are not comparable.
- Procurement outcome
- Delivered cost per dry tonne is comparable rather than apparent.
- Buyer concern
- Size range with no screening method
- What we do
- We require the distribution and the method behind it, since the receiving process depends on both.
- Procurement outcome
- The material suits the process step it was specified for, rather than being discovered unsuitable at receipt.
- Buyer concern
- Chemistry limits assumed rather than set
- What we do
- Limit fields stay empty until you set them. The tool supplies no defaults and no tolerance limits.
- Procurement outcome
- The acceptance criteria on the enquiry are yours, and the same criteria apply to every offer compared.
- Buyer concern
- Evidence requested too late
- What we do
- The document set is named in the enquiry and each document is tied to what it verifies.
- Procurement outcome
- The hold point is a check against an agreed set rather than a negotiation.
Advantages describe procurement practice. They make no claim about stocking position, mine or mill ownership, origin, delivered tonnage, pricing position or certification status.
From enquiry to delivery
Who owns what, at every stage
A grade order moves through defined stages. Each stage below names the concern it resolves, who owns it, what has to be supplied, what comes out of it, and the risk if it is skipped.
| Stage | Buyer concern | Owner | Required input | Evidence / output | Risk if skipped | Next action |

| Mineralogy vs grade separated | A descriptive name is being treated as a specification. | Buyer / technical sourcing | The mineralogical description and the contractual grade field, stated separately. | A requirement expressed in contractual fields. | The enquiry quietly becomes a comparison of labels. | Restate the requirement in grade, basis and limits. |
| Specification validation | A figure without a method cannot be verified. | Buyer / plant metallurgist | Assay, moisture and size methods named. | Basis resolved and stated. | Assays cannot be reproduced at receipt. | Close the missing evidence. |
| Evidence review | The documents must satisfy the contract. | Supplier and appointed inspection party | Sampling regime and required document set. | COA, moisture, size and inspection records. | The hold point becomes a negotiation. | Confirm against the agreed set. |
| Commercial basis | Price and quantity must rest on one basis. | Buyer / supplier commercial | Mass basis, quantity, cadence and Incoterm. | Quotation on a stated basis. | Wet and dry quantities cannot be reconciled. | Agree the basis in writing. |
| Destination and logistics | The movement must match the contract. | Supplier / carrier | Port or place, Incoterm, loading form, documents. | Shipping and customs document set. | Documents missing at the destination. | Confirm the document set before loading. |

Buyer FAQ
Questions that come up once offers are on the table
These are the questions traders, steel-plant buyers and procurement analysts raise once an offer exists — not what a grade figure means, but what has to be pinned down before two offers can be compared.
What specification fields should a buyer provide for High Grade Iron Ore?
Send the product form, the Fe target together with the basis it is reported on, your own chemistry limits for SiO2, Al2O3, P and S, the moisture basis and value, the size distribution and the method behind it, the sampling and inspection basis, the intended process route, quantity and cadence, destination port or place, Incoterm with named place, and the documents you require. The mineralogical name alone does not carry any of these, and it is the fields — not the label — that make two offers comparable.
How should Fe grade and impurity limits be verified?
Against a named assay method and a named sampling standard, on a stated moisture basis. An Fe figure reported on a wet basis and one reported on a dry basis are not the same number, so the basis belongs beside the value. Impurity limits come from your process rather than from us, and each limit should be tied to the method that will verify it at your hold point. A grade label does not establish any of this on its own.
Why should moisture and size distribution be stated with a test basis?
Because both change the commercial and process comparison. Moisture determines how wet and dry tonnage reconcile and carries directly into price per ton. Particle-size distribution governs how the material behaves in the receiving process. Without a determination method for each, two offers can appear comparable while resting on different measurements, and the difference surfaces at receipt rather than at quotation. This matters more, not less, on a nominally high-grade ore.
Which quality and inspection documents should be requested rather than assumed?
Request each one explicitly: a certificate of analysis per lot, a moisture determination report, a size distribution report, the sampling and inspection record, and the origin and shipping documents. They are separate documents answering different questions. Assuming a document is included is the most common cause of a hold point delay, because the accepted level is set by your contract rather than implied by the material.
Which commercial and delivery inputs are needed for a comparable RFQ?
Quantity and cadence, the mass basis the quotation is priced on, the destination port or named place, the Incoterm and named place, the loading or packing form, the document set, and the required delivery window. Without these the returned figures are descriptive rather than comparable, and two quotations for the same tonnage can differ purely because they assume different bases.

Unresolved verification items travel with this RFQ. If the basis, method or document level is still open, it is listed as a question rather than assumed.
Composition
What the chemistry behind an Fe grade actually constrains
Every figure below is a field your enquiry has to state. The grade figure covers only the first one; the rest are established independently and none are published as values on this page.
| Composition field | Buyer implication | Unit / basis | Verification method | Applicability / limitation | RFQ field or next action |
|---|---|---|---|---|---|
| Fe (iron) | The primary commercial field — but only comparable when the basis it is reported on is stated. | % — dry or wet, declared | Assay by the method the contract names | A grade label does not establish the measured figure or its tolerance | State the Fe target and its basis |
| SiO2 (silica) | Raises slag volume and, at high levels, increases the energy needed per tonne of iron. | % — dry basis as tested | Assay per the agreed method | Independent of the dominant iron mineral | Enter your process limit explicitly |
| Al2O3 (alumina) | Affects slag viscosity and, at higher levels, can disrupt stable furnace operation. | % — dry basis as tested | Assay per the agreed method | Independent of the dominant iron mineral | Enter your process limit explicitly |
| P (phosphorus) | Carries through to the steel and is difficult to remove downstream, so limits tighten on higher-grade products. | % — dry basis as tested | Assay per the agreed method | Critical on direct reduction and steelmaking routes; less so on some sinter routes | Enter the maximum explicitly |
| S (sulphur) | Route-dependent; more tightly constrained where the process is sensitive to sulphur in hot metal. | % — dry basis as tested | Assay per the agreed method | Acceptance depends on your specific route | Enter the maximum explicitly |
| LOI (loss on ignition) | Indicates the mass lost on heating — higher in hydrated forms, which affects the effective yield per wet tonne. | % — determination basis stated | Determination per the named method | Not an acceptance limit unless your contract makes it one | State the requirement or mark unresolved |
| Moisture | The field the commercial basis rests on — it decides how wet and dry tonnage reconcile. | % — as received or as determined | Determination per a named moisture method | Determined by handling and weather as well as by the deposit | State basis plus method |
Evidence warning. No value, range or tolerance for any composition field is published on this page. Every figure depends on the deposit, the product form and the lot, and each must be established by a named method on a stated basis. Request them per lot with their unit and basis.
Equivalents
What a high-grade label is equivalent to — and what it is not
Grade designations travel between markets in loose language. Before you treat one offer as equivalent to another, establish which of the four axes below actually matches.
Equivalent on the grade axis only
Two offers both described as high grade match on a word. There is no shared figure to compare, so the equivalence extends to nothing at all until a definite Fe value, its method and its tolerance are stated on both.
What to do: Ask each offer for a definite Fe figure with its basis before treating two high-grade descriptions as the same material.
Adjacent bands are not equivalents
62%, 63.5% and 65% Fe are distinct commercial bands, and “high grade” does not tell you which one you are looking at. Each band carries its own impurity profile and often its own penalty structure, so the descriptor is not a substitute for the figure.
What to do: Ask which band the offer sits in, then compare the full acceptance schedule rather than assuming the figures interpolate.
Mineralogy is a different axis
Hematite and magnetite can be sold against the same nominal Fe band while behaving differently in reduction, in mass yield and in the product form delivered. Grade equivalence does not imply mineralogical equivalence.
What to do: Confirm the mineralogical form separately when your route is sensitive to it.
Product form is a different axis again
Concentrate, fines, lumps and pellets at the same Fe grade are four different decisions. The form determines the handling, the process step and much of the document set.
What to do: State the required form explicitly; never infer it from the grade figure.
Test method underpins any equivalence claim
Two Fe figures produced by different analytical methods are not directly comparable, even at the same nominal grade and basis. The method is what makes an equivalence claim defensible.
What to do: Require the method to be named in the offer and matched at your receipt.
Commercial equivalence is a separate question
An offer can be technically equivalent and commercially incomparable — different mass basis, different Incoterm, different document set. Technical equivalence does not imply a comparable quotation.
What to do: Compare quotations on a stated mass basis, destination and document set.
This page publishes no equivalence table, conversion factor or cross-standard mapping for any grade. Grade designations are commercial conventions whose tolerances are set buyer-seller in the contract, and no mapping can substitute for the schedule your contract names.
MTC requirements
What an MTC does and does not evidence on a grade enquiry
A mill test certificate is the document a grade offer is usually evidenced by. It is worth being precise about what it covers, because an MTC is frequently treated as more than it is.
| MTC content | What it evidences | Applicability / limitation | Verification requirement | RFQ field or next action |
|---|---|---|---|---|
| Heat or lot identification | That the certificate belongs to a specific production lot rather than to a general product description. | Only meaningful if the lot it names is the lot delivered; a generic certificate evidences nothing about your shipment. | Match the certificate's heat or lot reference against the shipping and packing documents. | State that lot traceability is required, and to what level. |
| Chemical composition results | The measured chemistry of the sampled lot, to the extent the methods used cover it. | Covers only the elements reported and only to the method's scope. A grade figure does not oblige a certificate to report every element your contract constrains. | Confirm the elements reported match your acceptance schedule, not just the Fe figure. | List every element your contract limits, and require each to be reported. |
| Analytical methods used | Whether the reported figures were produced by a method you can compare against your own receipt. | A certificate reporting values without naming methods cannot be reproduced or disputed on equal terms. | Compare the named method against the standard your contract cites. | Require the method to be named for each reported field. |
| Sampling basis | Whether the results came from a representative sample of the lot. | A result is only as defensible as the sampling behind it; the certificate rarely states this in full. | Confirm the sampling regime separately against your contract's sampling standard. | Name the sampling basis in the RFQ rather than assuming the MTC implies it. |
| Issuing party and accreditation | Who produced the certificate and under what recognition. | This page makes no claim about which laboratories are used, or about any party's accreditation status. | Confirm the issuing party meets whatever your contract or end user requires. | State any requirement you have for the issuing party. |
| Results outside your scope | Fields the certificate reports that your contract does not actually constrain. | Reporting a field does not make it an acceptance criterion; equally, its absence does not breach a contract that never asked for it. | Align the certificate's scope with your acceptance schedule in both directions. | Review the certificate scope against your schedule before the hold point. |
No certificate is reproduced, referenced or implied on this page. This section describes what an MTC covers in general terms. It makes no claim about which certificates Noor Deira Steel issues or holds, and the certificate that accompanies your lot is the one that applies to your lot.
MTC checklist before the hold point
- The lot reference on the certificate matches the lot on your shipping documents.
- Every element your contract limits is reported, not only the Fe figure.
- Each reported figure names the analytical method that produced it.
- The sampling basis behind the results is stated, or confirmed separately.
- The issuing party meets whatever your contract or end user requires.
- Fields the certificate reports are checked against your schedule in both directions.
