What this guide decides
Interpret demand-to-supply ratios alongside traded volume, repetition and product mix so one excited offer is not mistaken for sustained pressure.
Executive summary
- Main decision: Interpret demand-to-supply ratios alongside traded volume, repetition and product mix so one excited offer is not mistaken for sustained pressure.
- Comparison basis: Calculate within comparable products using volume weighting. Display offer count, tonnage, traded share, final-price premium over base and persistence over several weeks.
- First risk: Overstating small offers
What decision are you making?
Demand divided by offered volume indicates competitive pressure. A ratio above one may show excess orders, but its meaning depends on effective demand and comparable products. 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]
These articles explain Iran's domestic steel market so international buyers can interpret supplier quotations and delivery signals. Keep Iranian exchange transactions and domestic warehouse prices distinct from an export offer. Confirm whether figures are in rial or toman, per kilogram or tonne, and inclusive or exclusive of applicable taxes. Then request the agreed settlement currency, named export port or delivery location, packing, freight and shipment documents, checking the destination project's material requirements. Domestic market data provides context; the supplier's current confirmed offer governs the actual purchase.
Technical mechanism and price impact
High demand is a stronger signal when it converts into trades and higher prices repeatedly. A large ratio on a small or unusual offer may not represent the market. The sold share and producer distribution complete the picture.[2][3][4]
Calculate within comparable products using volume weighting. Display offer count, tonnage, traded share, final-price premium over base and persistence over several weeks. 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:
- Supply and demand tonnage
- Traded volume
- Offer count and variety
- Price competition premium
- Persistence across periods
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.
| High ratio and full sale | Stronger evidence of demand pressure | Repetition and final-price increases |
| High ratio and limited sales | Ineffective orders or unsuitable terms | Delivery conditions and base price |
| Low ratio and stable price | Balance or weak activity | Inventory and open-market demand |
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: Overstating small offers; Combining unlike products; Omitting the sold share; Drawing conclusions from one day. 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
The ratio is a signal rather than a purchasing instruction. Consider intensity, volume, trade conversion and persistence together.[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 demand-to-supply ratio?
Align the product definition and acceptance criteria before comparing prices. Calculate within comparable products using volume weighting. Display offer count, tonnage, traded share, final-price premium over base and persistence over several weeks.
Is price alone enough to decide on steel demand-to-supply ratio?
No. Prices are comparable only when grade, dimensions, weight, quality, documents, delivery scope and validity match. The ratio is a signal rather than a purchasing instruction. Consider intensity, volume, trade conversion and persistence together.
