Fluorspar in steelmaking: RFQ, COA and acceptance checks

For steelmaking procurement, fluorspar should be specified as a furnace input: define the operating context, compare chemistry and physical form on the same basis, and agree sampling and acceptance before shipment.

What operating and charging information should a buyer provide?

A supplier cannot prepare a comparable offer from a grade name alone. The buyer should explain the intended furnace or steelmaking route, the material's flux role, the charging point, and the physical-handling conditions that affect suitability.

The purpose is not to prescribe a furnace practice. It is to make clear which parts of the material and delivery need to fit the buyer's process before a quotation is compared.

Furnace or process route, together with the intended flux or slag-control role.
Charging point, feed method, expected physical form, and any handling or dust constraint relevant to the plant.
Required CaF2 target and the impurity fields that the plant or contract needs to control.
Expected quantity, packing preference, destination, delivery window, and any buyer document requirement.

How should steelmaking offers be compared?

Compare offers only when the quoted fields use the same measurement and commercial basis. A higher headline CaF2 number does not make two offers comparable if the impurity limits, size definition, moisture basis, packing, or inspection responsibility differ.

Fields to align before comparing a fluorspar offer for steelmaking
Field	What to confirm	Why it belongs in the comparison
Chemistry	CaF2 and any SiO2, CaCO3, sulphur, phosphorus, or other contract-relevant limits	The plant and contract need the same set of declared limits.
Particle size	Range, fines or oversize treatment, and the measurement method	Physical form affects charging and handling decisions.
Moisture	Limit, measurement basis, and whether the figure is as received or another agreed basis	Moisture affects usable material, handling, and the comparison of commercial terms.
Packing and quantity	Bag type, unit weight, loading basis, and requested quantity	Packing assumptions can change handling and delivered-cost comparisons.
Inspection	Sampling plan, laboratory or test method, timing, and acceptance responsibility	A result is only useful when it is tied to an agreed verification process.

This is a procurement comparison framework. The final limits and test procedures should be agreed by the buyer and supplier in the contract or inspection agreement.

What documents and acceptance terms are needed on arrival?

Receiving teams need documents that connect the material delivered to the agreed specification. The exact list depends on the transaction, but the COA should not sit apart from the lot reference, packing record, and agreed inspection basis.

A COA that identifies the relevant batch, lot, or shipment and reports the agreed chemistry and moisture fields.
A packing list and commercial shipment documents that use the same lot or cargo references where applicable.
An inspection report when the contract requires one, with the sample identity and test basis stated.
A written sampling and testing agreement covering how samples are taken, how composite or retained samples are handled when required, the test method, and how acceptance is decided.

What should a steelmaking fluorspar RFQ include?

A useful RFQ gives each supplier the same technical and commercial frame. Missing or unclear fields can lead to offers that look similar but are based on different chemistry, moisture, packing, or inspection assumptions.

Application, furnace or process route, flux role, charging point, and handling constraints.
Required product form, CaF2 target, relevant impurity limits, particle-size range, and moisture basis.
Quantity, packing, destination, target shipment window, and applicable Incoterms.
Required COA fields, lot identification, sampling method, test method, third-party inspection requirement if any, and acceptance basis.

Practical takeaway

Steelmaking buyers should treat fluorspar as an operating input rather than a commodity line item. The strongest comparison connects plant requirements, the quoted specification, and the documents used to accept the shipment.

Common questions

What should a steelmaking buyer tell a fluorspar supplier first?

State the furnace or process route, flux role, charging and handling conditions, required chemistry, size, moisture basis, quantity, packing, destination, and inspection requirements.

Which fluorspar fields should be compared before price?

Compare CaF2, contract-relevant impurities, particle size, moisture basis, packing, quantity, destination, and inspection terms on the same basis.

What makes a fluorspar COA useful for steelmaking acceptance?

It should identify the relevant lot or shipment, report the agreed fields, and be read with the agreed sampling and test method.

Should sampling be agreed before shipment?

Yes. The sampling method, test method, sample identity, and acceptance basis should be agreed before the cargo is used for a contract decision.
