I. Why Standardized Defect Terminology Matters?
In third-party inspection, inspectors are required to classify and mark defective products on-site and present the findings in the final official inspection report. A professional inspection report must include accurate defect descriptions that allow clients to quickly understand the issues and provide a reference for goods release decisions.
Inspector Online, a professional third-party inspection agency with 20 years of industry experience, has compiled this industry-wide universal glossary of common defects based on over 100,000 inspection services conducted annually. It covers major export product categories including textiles and apparel, electronics and electrical appliances, furniture and home goods, toys and gifts.
II. Defect Severity Classification Terminology
All product defects are first categorized into three levels based on their impact on user safety, product functionality and appearance. This is the foundation of the internationally accepted AQL (Acceptable Quality Limit) sampling inspection standard:
| English Term | Chinese Term | Abbreviation | Definition & Typical AQL Value |
|---|---|---|---|
| Critical Defect | 致命缺陷 / 严重缺陷 | CR | Defects that endanger consumer health or safety, or violate laws and regulations of the target market. Zero tolerance. AQL value is typically 0. |
| Major Defect | 主要缺陷 | MAJ | Defects that directly affect the core functionality or primary appearance requirements of the product, rendering it unfit for normal use. AQL value is typically 1.0 or 2.5. |
| Minor Defect | 轻微缺陷 / 次要缺陷 | MIN/MI | Defects that do not affect the normal use of the product and only present minor appearance imperfections. AQL value is typically 4.0. |
III. Universal Appearance Defects (Chinese-English)

V. How to Use These Terminologies Correctly
- Combine with Severity Levels: Always indicate the severity level (CR/MAJ/MIN) when describing defects, as this is the core basis for AQL inspection judgment.
- Quantitative Description: Quantify the size, quantity and location of defects whenever possible, e.g., “3 scratches over 5mm in length on the front surface”.
- Combine Text with Images: Professional inspection reports include clear photos for each defect. Text descriptions paired with images convey issues more accurately.
