How We Conduct Inspection Based on AQL Rules?
Our Core Inspection Standard: AQL
All our pre-shipment inspections for general merchandise and full-range export goods adopt the internationally recognized AQL (Acceptable Quality Level) sampling standard, which is widely used in global quality control industry to balance inspection efficiency and product quality stably.
Based on AQL rules, we provide two professional inspection solutions for clients: Partial Inspection (AQL Random Sampling) and Full Inspection (100% Full Checking).
What is AQL?
AQL refers to the maximum acceptable number of defective products permitted in a production batch during random sampling inspection. It is a scientific and objective quality judgment rule, avoiding subjective manual evaluation. We classify all product defects into three levels with fixed universal standards for all categories:
- Critical Defect (CR): AQL=0 Zero tolerance, any safety hazard or completely unusable product leads to direct batch failure
- Major Defect (MAJ): AQL=2.5 Defects affecting product function, assembly and sales appearance
- Minor Defect (MIN): AQL=4.0 Slight cosmetic flaws without any impact on usage, function and sales
Based on AQL rules, we provide two professional inspection solutions for clients: Partial Inspection (AQL Random Sampling) and Full Inspection (100% Full Checking).
Partial Inspection (Standard AQL Random Sampling Inspection)
This is our most commonly used inspection solution for mass production orders.
Inspectors conduct blind random sampling strictly following ANSI/ASQ Z1.4 AQL standard on site, without allowing factories to select qualified cartons in advance. We only inspect qualified sampled goods instead of checking every product to save inspection cost and shorten inspection cycle while controlling overall batch quality effectively.
Applicable Scenarios: Large-volume mass production, stable factory QC capability, long-term repeated orders, general daily necessities, household goods, common hardware and regular textile products.
Judgment Basis: Count defective goods after full-item inspection of samples; pass the whole batch if defect quantity is within AQL limit, otherwise reject the batch and require factory rework.
Full Inspection (100% Complete Full-Check Inspection)
Full inspection means inspecting every single product and all packaging one by one without any sampling omission. Our QC team will conduct full appearance, dimension, function and packaging tests for all finished goods, pick out all defective products including critical, major and minor defects, and separate non-conforming goods completely from qualified goods before shipment.
Applicable Scenarios: High-value goods, premium customized products, first cooperation with new manufacturers, orders with poor previous quality performance, small batch orders, and customers with extremely strict quality requirements.
Core Advantage: Zero defective goods shipped, maximum quality risk control, suitable for high-standard overseas markets.
