Critical Defect

Critical Defect is a core term in foreign trade quality inspection, referring to a defect that endangers personal safety, causes complete loss of function, or seriously violates laws and regulations. Usage scenarios include: factory inspection, pre-shipment inspection, customer complaint handling, and contract quality clauses. Notes: 1) Distinguish from Major Defect and Minor Defect: critical defects usually lead to rejection or recall of the entire batch, major defects affect use but can be repaired, and minor defects are only cosmetic flaws; 2) In AQL sampling standards, the acceptance quality limit for critical defects is usually 0 (i.e., not allowed); 3) Contracts should clearly define critical defects and their consequences, such as returns, claims, or penalties; 4) Different industry standards (such as electronics, toys, and textiles) have different definitions of critical defects. Foreign trade practitioners need to specify the inspection basis in the contract to avoid disputes caused by vague definitions.
