What this guide decides
Choose the document type from risk and contract requirements, then verify authenticity, scope, results and linkage to the heat and product.
Executive summary
- Main decision: Choose the document type from risk and contract requirements, then verify authenticity, scope, results and linkage to the heat and product.
- Comparison basis: Record certificate type, issuer and inspector, standard and grade, heat or lot, product and dimensions, required results, language, revision and validation process.
- First risk: Altered PDF
What decision are you making?
Inspection documents provide different levels of conformity declaration and test results. The terms 3.1 and 3.2 define relationships between issuer, inspection and product rather than simply naming a file. 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]
When importing steel from Iran, price differences often reflect weight basis, local tax treatment, delivery location, cutting, packing, freight, quote validity and documentation. Keep one order, lot and acceptance reference from RFQ through discharge and any claim. Specify settlement currency, the named port or final delivery place, inspection language and destination project requirements. Ask the responsible parties to confirm applicable border charges and documents for the actual shipment rather than assuming that an Iranian domestic quote represents the importer's landed cost.
Technical mechanism and price impact
A valid document should identify relevant standard and grade, heat or lot, dimensions, quantity and chemical and mechanical results. Transfers and recertification require an intact traceability chain.[2][3][4]
Record certificate type, issuer and inspector, standard and grade, heat or lot, product and dimensions, required results, language, revision and validation process. 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:
- Manufacturer identity
- Heat and product
- Standard and grade
- Results and acceptance limits
- Authenticity and traceability transfer
Compare the options
Use this table to structure the decision. It does not replace engineering calculations or the contract. The final column identifies the evidence to review before accepting an offer.
| 2.2 | The contract accepts a nonspecific test report | Scope and declaration |
| 3.1 | Specific results and manufacturer validation are required | Independence of the validating representative |
| 3.2 | Buyer or designated third-party validation is required | Responsibilities and witnessing |
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: Altered PDF; Certificate for another heat; General results replacing specific tests; Cutting without transferring marks. 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
Do not accept a document by its title alone. Every result must connect to a heat, and every heat to the delivered material.[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 steel inspection certificates?
Align the product definition and acceptance criteria before comparing prices. Record certificate type, issuer and inspector, standard and grade, heat or lot, product and dimensions, required results, language, revision and validation process.
Is price alone enough to decide on steel inspection certificates?
No. Prices are comparable only when grade, dimensions, weight, quality, documents, delivery scope and validity match. Do not accept a document by its title alone. Every result must connect to a heat, and every heat to the delivered material.
