A Buyer-Ready Checklist Before Sending Drawings
Structure your RFQ so engineering can review manufacturability, material, finish, quantity and inspection needs with fewer clarification cycles.
Must-have RFQ inputs
2D / 3D drawings
PDF with revision control plus STEP/STP/IGES/DWG when available. ZIP is fine for multi-file sets.
Material & finish
Grade, temper/condition, plating/passivation/anodizing/heat treatment callouts and masking notes.
Quantity plan
Prototype / pilot quantity, first release and estimated annual volume for process planning.
Critical tolerances
Datums, threads, bores, concentricity, cosmetic faces and assembly-critical features.
Application context
Industry, mating parts, environment and packaging needs — optional but accelerates route selection.
Inspection needs
FAI, dimensional reports, material certs or other release documents required by your quality system.
Best RFQ package
- PDF drawing + STEP/DWG if available
- Material, finish, hardness and special treatment requirements
- Prototype quantity, batch quantity and estimated annual volume
- Critical dimensions, threads, bores and assembly surfaces
- NDA, certificate and inspection report needs
