Defect Classification

Defect Classification is a core term in foreign trade quality control. It refers to the categorization of nonconforming products into different levels based on the severity of the defect, its impact on product function or safety, and customer acceptance. It is typically divided into Critical, Major, and Minor defects. Usage scenarios include: inspection reports (such as AQL sampling), supplier corrective actions, contract quality clauses, claim negotiations, etc. Note: Different customers or industries may have different definitions of defect levels, so it must be clearly defined in the contract or inspection standards. Also note the difference from 'Defect Category' (which classifies by the nature of the defect, such as appearance or function); the former emphasizes severity, while the latter emphasizes type. In addition, defect classification directly affects the judgment of AQL sampling plans (e.g., critical defects usually require zero tolerance), so accurately understanding and unifying standards can help avoid trade disputes.
