Common L/C Discrepancies to Avoid
Build a supplier quality scorecard. My dimensions: product pass rate 40%, on-time delivery 25%, cooperation 15%, price 10%, response speed 10%. Any supplier below 80 for three months needs reassessment.
Photo and video documentation before shipment prevents disputes. Randomly photograph 10 cartons during packing. Focus on product details, packaging, and shipping marks. This evidence is your strongest defense against claims.
AQL sampling is the foundation. Determine sample size based on batch quantity, then use the acceptable quality level to decide pass or fail. If defective units exceed the limit, the batch needs 100% inspection or rework.
Different products need different inspection focuses. Metals: dimensional tolerance and finish. Electronics: functional testing and ESD. Textiles: color and defects. Ceramics: deformation and glaze. A one-size-fits-all checklist is unprofessional.
