What this guide decides
Identify the exact product, quality, location, timing and trade terms represented by an assessment before comparing it with your purchase.
Executive summary
- Main decision: Identify the exact product, quality, location, timing and trade terms represented by an assessment before comparing it with your purchase.
- Comparison basis: Record assessment name and symbol, product, grade or analysis, dimensions, price unit, origin and destination, Incoterm, loading window, assessment time and treatment of taxes or duties.
- First risk: Using an unrelated benchmark
What decision are you making?
Platts publishes commodity price assessments and market specifications through S&P Global Commodity Insights. Each symbol has a defined technical and commercial basis. 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
Assessments use collected and verified market information, normalizing differences such as quality, location, timing and delivery terms. They need not equal a simple average of all trades or the latest observed offer, and should be read with the specifications and assessment rationale.[2][3][4]
Record assessment name and symbol, product, grade or analysis, dimensions, price unit, origin and destination, Incoterm, loading window, assessment time and treatment of taxes or duties. 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:
- Full assessment name and symbol
- Current specification-guide edition
- Assessment location and time
- Units and currency
- Delivery terms and loading window
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.
| Closely matched benchmark | Product and terms resemble the specification | Every specification parameter |
| Reference with adjustments | No direct local benchmark exists | Documented quality, freight, currency and financing bridge |
| Independent domestic price | Trade constraints or local scarcity dominate | Actual trades, IME records and current quotes |
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: Using an unrelated benchmark; Omitting basis-conversion costs; Confusing assessment with prediction; Quoting without date or symbol. 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
Read the definition before the number. For Iranian supply, use the assessment as a baseline and build a transparent bridge to replacement cost or an actual domestic or export offer.[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 Platts price assessments?
Align the product definition and acceptance criteria before comparing prices. Record assessment name and symbol, product, grade or analysis, dimensions, price unit, origin and destination, Incoterm, loading window, assessment time and treatment of taxes or duties.
Is price alone enough to decide on Platts price assessments?
No. Prices are comparable only when grade, dimensions, weight, quality, documents, delivery scope and validity match. Read the definition before the number. For Iranian supply, use the assessment as a baseline and build a transparent bridge to replacement cost or an actual domestic or export offer.
