What Should You Include in a Manufacturing RFQ? A Buyer Preparation Guide

1. Product Information

Start with enough information for a supplier to know what they are quoting. If the supplier has to imagine the product, the quotation will carry their imagination — and a margin to cover the uncertainty.

• Product description. What it is, what it does and how it is used.
• Drawings. 2D drawings with dimensions and tolerances, or 3D models (STEP/IGES) where relevant.
• Images. Photos or renders showing the product, its finish and its use context.
• Reference samples. A physical sample the supplier can examine is the clearest specification of all.

Reference samples deserve special attention in China sourcing. A physical sample communicates finish, texture and assembly feel that drawings cannot — and it becomes the visual anchor for approved-sample checks later.

2. Technical Requirements

Technical requirements define what the product must be made of and how precisely it must be made. Vague here means the supplier will choose the cheapest interpretation.

• Materials. Exact grade (for example ABS or ABS/PC blend), color, and any required compliance (food contact, flame retardant).
• Dimensions. Key dimensions with tolerances — and only the tolerances that matter to function.
• Finishes. Surface finish, texture, gloss level and cosmetic requirements.
• Testing requirements. Function tests, drop tests, electrical or safety tests the product must pass.

State which tolerances are critical and which are for reference. Suppliers quote scrap risk on the tightest call, so an over-specified drawing costs you money even when the tolerance is not actually needed.

3. Manufacturing Requirements

Tell the supplier how the product should be made and what is included in the quotation. The manufacturing scope decides the price far more than the drawing does.

• Process. The intended process: injection molding, die casting, stamping, assembly or a combination.
• Tooling. Whether tooling is included, whether tooling cost is quoted separately, and the expected mold life.
• Assembly. Whether sub-assembly and final assembly are in scope and where they happen.
• Packaging. Required packaging standard, labeling and export carton specifications.

Ask for tooling and unit price as separate line items. A quotation that bundles them hides how much the mold really costs and makes price comparison across suppliers impossible.

4. Quantity and Forecast

Quantity is the biggest driver of unit price, so the RFQ must state it honestly. Suppliers price against volume assumptions — a misleading number produces a misleading quote.

• MOQ. The minimum quantity you expect to order per item per order.
• Initial order. The quantity of the first order — this is what tooling and setup costs are amortized against first.
• Annual volume. The expected total volume per year, which lets the supplier plan material and capacity.

If you only have a rough forecast, say so and give a range. A supplier who knows you expect 50,000 units a year can price material and molding time differently from one who assumes a one-off 2,000-unit order.

5. Quality Requirements

Quality requirements tell the supplier what standard the goods will be judged against. Leaving this out means the supplier will assume a loose default — and the first disagreement about defects will be about what was agreed.

• Inspection standards. The sampling standard and acceptance criteria (for example AQL levels) to be applied.
• Approved samples. That the first article and production samples must be approved before mass production.
• Testing requirements. Which tests the supplier must run and which results must be documented.

Also state who inspects: the supplier's own QC, a third-party inspection company, or both. When third-party inspection is planned, name it in the RFQ so the supplier includes the cost and arranges access.

6. Commercial Requirements

Commercial terms determine how the quotation is structured and compared. Define them in the RFQ so every supplier answers on the same basis.

• Quotation format. Ask for a standard breakdown: tooling, unit price by quantity tier, lead time, packaging, payment terms.
• Incoterms. State the delivery terms you want quoted (for example FOB, EXW or CIF) so prices are comparable.
• Payment terms. State the payment basis you expect, such as a deposit plus balance against shipping documents.
• Tooling costs. Whether tooling is paid separately, its payment schedule, and who owns the mold.

Mold ownership deserves a written line: who owns the tool after it is paid for, and what happens at the end of the program. An ambiguous tooling clause is a common source of disputes when buyers later change suppliers.

RFQ Checklist: What to Include

Use the checklist below to review an RFQ before sending it — anything left out will come back as an assumption in the quotation.

A complete RFQ is also a negotiation asset: when all suppliers answer the same structured request, the quotations can be compared cell by cell, and the differences — material grade, inspection scope, packaging — become visible instead of hidden. We provide a ready-to-use RFQ preparation template (PDF) built on these sections.

Practical Takeaway

The RFQ is the single document that determines how accurate and comparable your quotations will be. Give every supplier the same complete package — product, technical, manufacturing, quantity, quality and commercial requirements — and ask for a structured response on the same Incoterm. The hour spent writing a proper RFQ saves weeks of clarifying quotes and prevents the assumption-based surprises that show up later as cost and quality issues.
