A vague enquiry produces either a wide price range or a low quote that grows after the order. Both waste a procurement cycle. A complete RFQ takes about ten minutes to prepare.
The twelve data points
- Item name and intended function, in one line.
- Standard or drawing: standard number, or drawing files (PDF plus DWG/DXF where dimensions are critical).
- Material grade: Q235, 45#, 40Cr, 20MnTiB, stainless 304/316 — or the mechanical properties required if the grade is open.
- Property class: 4.8, 8.8, 10.9, or a specified yield and tensile requirement.
- Dimensions: diameter, pitch, length, and the tolerances that matter.
- Thread details: system, class, thread length, and whether threads are rolled or cut.
- Surface finish: standard plus measured thickness range, and whether threads must assemble after coating.
- Quantity: pieces or sets, plus expected annual volume if any — volume changes tooling decisions and price.
- Packing: unit, marking requirement, and whether packing must follow a BOM or drawing structure.
- Documentation: certificate type, test reports, third-party inspection requirement.
- Delivery: destination port or address, Incoterm, and the date material is needed on site — not the date it would be nice to have it.
- Commercial terms: currency, payment terms, and any MOQ constraint the buyer must work within.
Why each missing item costs money
Missing grade: the factory quotes the cheapest grade that fits the visible description, so the quote is not comparable to a competitor's 40Cr quote.
Missing tolerance: the factory assumes a commercial tolerance. A ±2 mm requirement quoted against a ±5 mm assumption becomes a dispute.
Missing coating thickness: "galvanized" becomes whichever thickness is cheapest to apply, usually below what the site environment needs.
Missing documentation: certificates are added later as a variation, at a price, and the shipping date slips.
Missing packing structure: kits arrive as bulk bags and the site spends a week sorting — a cost that never appears on the purchase order.

Making the comparison fair
Ask every supplier to quote the same line items and to break price into material, processing, coating, packing and freight. When one quote is 20% below the others, the breakdown usually shows which line was assumed differently — often grade or coating — rather than a genuine cost advantage.
Require quotation validity and lead time from order confirmation, not from enquiry. Then you are comparing two quotes that mean the same thing.
