A complete RFQ reduces assumptions, shortens quotation time, and gives suppliers a clearer basis for process and quality planning.

Start with usable geometry

Send a 3D model for geometry and a 2D drawing for dimensions, tolerances, threads, notes, and inspection requirements. STEP or STP files are a practical default for many machined and molded parts.

Describe the commercial scope

Include quantity, expected repeat volume, target delivery date, shipping country, and whether the request is for prototype, pilot, or production.

Separate critical from standard requirements

Highlight the dimensions, surfaces, fits, and cosmetic areas that control function. Avoid applying the tightest tolerance to every feature unless the design truly requires it.

State documentation needs early

Material certificates, inspection reports, first-article records, packaging rules, and third-party inspection should be included before quotation.
