100% Inspection

100% Inspection refers to the quality inspection of every single product in a batch, rather than sampling inspection. In foreign trade, 100% inspection is typically used for high-value, high-precision, or safety-critical products (such as electronic components, medical devices, automotive parts), or when customers have strict quality requirements and the contract explicitly stipulates it. Use cases include: customer specifies 100% inspection, products have previously received quality complaints, or as the final quality checkpoint before shipment. Precautions: 100% inspection is costly and time-consuming, and may cause delivery delays. Therefore, the contract should clearly specify inspection standards, sampling plans (such as AQL), who bears the inspection costs, and how non-conforming products are handled. Difference from 'sampling inspection': sampling inspection only checks a portion of samples, which is higher risk but lower cost; 100% inspection ensures every product is qualified, but is less efficient. Opposite to 'inspection exemption', 100% inspection does not rely on the supplier's historical quality. Foreign trade practitioners should weigh quality against cost to avoid excessive 100% inspection reducing profits.
