The quality control & inspection workflow.
AQL 2.5 is the accepted B2B standard for promotional merchandise. It means: in a representative sample drawn from your batch, no more than 2.5% of pieces can have major defects (functional failure, conspicuous visual flaw) and no more than 4.0% can have minor defects (small surface imperfection, slight color drift).
For higher-spec programs (jewelry-grade brooches, military-issue pins, prep-school crests) we run tighter AQL 1.5 inspection at no extra cost — sample sizes are larger and acceptance thresholds tighter.
Step by step.
01 / Incoming material QC
Brass blanks, enamel paste, plating chemicals, and packaging materials all tested upon delivery.
02 / In-process QC
Spot-checks after stamping, after coloring, and after plating. Defective pieces removed from the line.
03 / Pre-shipment AQL 2.5
ISO 2859-1 statistical sampling on the finished batch. Major defects ≤2.5%, Minor defects ≤4.0%.
04 / 3rd-party audit (optional)
SGS, BV, TUV, or Asia Inspection on-site inspection at buyer’s request and cost ($300-500/inspection).
05 / Defect report
Full inspection report with photos sent to buyer 1-2 days before shipment.
