FAQ

Questions Buyers Ask About Quality Control

AQL (Acceptable Quality Limit) is the maximum number of defective units you accept in a batch. For promotional products, AQL 2.5 for major defects and 4.0 for minor defects is the industry standard. During a pre-shipment inspection, an inspector randomly samples the batch using the AQL sampling table and rejects the shipment if defects exceed the limit. Specify the AQL level and inspection criteria in your purchase order so the factory knows your standards upfront.

At minimum, run a pre-shipment inspection on finished goods before they leave the factory. For higher-risk products, add an in-line inspection during production — typically when 20–30% of the order is complete — so defects are caught before the whole batch is made. For complex or high-value orders, inspect raw materials at the start too. Most defects are caught faster with an in-line check than by waiting until pre-shipment.

Document every defect with photos and the specific AQL criteria it violates, then issue a corrective action request to the factory before release. Sort-and-rework is common for minor defects; for major issues, withhold the remaining payment until the factory reworks and re-inspects the batch. Always confirm rework is re-inspected — never accept a verbal promise that defects were fixed.
