What this guide decides

Compare scrap with a suitable benchmark using composition, density, contamination, moisture and metallic yield.

Executive summary

  • Main decision: Compare scrap with a suitable benchmark using composition, density, contamination, moisture and metallic yield.
  • Comparison basis: Convert price to net meltable tonnes after moisture, contamination, preparation loss and freight. Keep melt yield separate from weighbridge mass.
  • First risk: Mixed grades

What decision are you making?

Terms such as HMS 1/2 and an 80:20 ratio define a commercial specification, not every form of used iron. Actual cargo quality directly affects metal recovery and preparation cost. Evaluate technical specifications, the price basis, delivery terms and quality evidence together. A lower number is not a comparable offer if it covers a different grade, weight, coating or delivery scope.[1][2]

For buyers comparing Iranian supply with international benchmarks, align product, grade, dimensions, assessment date, currency and delivery basis before discussing a premium or discount. Request an offer in the executable settlement currency at a named port or final delivery location, and show freight, insurance, handling, applicable charges and financing separately. Confirm destination acceptance of the material and documents. Iranian exchange and stockholder data can explain domestic supply conditions, but neither a benchmark nor a domestic quote is itself an executable export offer.

Technical mechanism and price impact

Dense, clean scrap generally improves charging and recovery. Soil, water, oil, nonferrous metals, closed containers and hazardous items increase cost and risk, making delivery location and inspection part of the benchmark definition.[2][3][4]

Convert price to net meltable tonnes after moisture, contamination, preparation loss and freight. Keep melt yield separate from weighbridge mass. Compare offers only after aligning units, the weight basis, taxes, packaging, loading, freight and quote validity. An omitted cost can outweigh the apparent saving per kilogram. Keep the supplier’s currency and payment date visible before converting to your purchasing currency.

Request comparable quotations

Ask every supplier to answer the same written specification. This prevents an apparently cheaper offer from silently changing the product or scope. Confirm the following before comparing prices:

  • Grade definition and mix ratio
  • Piece dimensions and density
  • Moisture and contamination limits
  • Sampling and rejection method
  • Delivery location and unloading responsibility

Common risks and warning signs

Errors often begin when a trade name replaces a technical specification, one photograph stands for an entire shipment, or the delivery scope is missing from the quote. Address these specific risks: Mixed grades; Hidden moisture; Copper and tin contamination; Closed containers or hazardous items. Turn each risk into a written acceptance criterion, sampling requirement or traceable document.

A standard number alone does not demonstrate conformity. Specify the edition, grade, dimensions, tolerances, test method, heat or batch number and acceptance authority. For an import project, confirm the destination’s requirements and the project’s approved specification; an Iranian market designation is not automatic evidence of an equivalent local grade.

Make the purchasing decision

A scrap benchmark approaches melting cost only when the cargo is correctly graded and its losses measured. Link weighing, analysis and inspection in one control chain.[4][5]

Before ordering, prepare a single comparison sheet covering the product, quantity, unit, theoretical and actual weight, base price, taxes, freight, delivery window, documents and acceptance criteria. Identify who pays each cost and who records discrepancies at receipt. This makes the negotiation clearer and gives the receiving team an agreed basis for checking the shipment.

Frequently asked questions

What should I check first when evaluating ferrous scrap benchmarks?

Align the product definition and acceptance criteria before comparing prices. Convert price to net meltable tonnes after moisture, contamination, preparation loss and freight. Keep melt yield separate from weighbridge mass.

Is price alone enough to decide on ferrous scrap benchmarks?

No. Prices are comparable only when grade, dimensions, weight, quality, documents, delivery scope and validity match. A scrap benchmark approaches melting cost only when the cargo is correctly graded and its losses measured. Link weighing, analysis and inspection in one control chain.
