Compare Factories Against the Same Written Brief

Factory comparisons become unreliable when each supplier quotes a different construction, plating, stone grade, packaging, inspection scope, or delivery term. Send the same RFQ package to every candidate and record assumptions separately. Include drawings or reference views, dimensions, base metal, plating, stones, logo, packaging, destination, estimated quantity, target date, testing needs, and intellectual-property restrictions.

  • Use one version number and issue date for every supplier brief
  • Separate confirmed requirements from options and open questions
  • Require each quotation to list exclusions, substitutions, and unresolved assumptions

Score Sample Control and Production Readiness

Ask who reviews feasibility, creates or checks CAD, controls master samples, approves material and plating, and records revisions. A strong sample is useful only when the supplier can reproduce it. Confirm how the approved sample is identified, which measurements and visual standards are controlled, what changes require buyer approval, and how a later reorder refers back to the same specification.

  • Feasibility review identifies missing or conflicting requirements
  • Sample approval records the exact revision and acceptable variation
  • Bulk production starts only after written approval and commercial confirmation

Evaluate Quality Control with a Defined Sampling Plan

Request defect definitions for critical, major, and minor issues, plus the inspection stage and record for each. Where acceptance sampling is used, define the applicable standard and plan instead of relying on a vague AQL claim. Sampling reduces inspection effort but does not guarantee that every unit is defect-free; buyers should set product-specific checkpoints and decide when 100% checks are necessary for safety or function.

Check Capacity, Documentation, and Commercial Terms

Capacity should be tested against the actual style mix, process route, plating batch, packaging work, and requested ship date. Verify whether key processes are in-house or subcontracted and who remains responsible. Compare sample fees, tooling ownership, MOQ, payment milestones, inspection rights, defect handling, delivery terms, confidentiality, change control, and reorder consistency before choosing a supplier.
