What is the standard AQL?

Under normal inspection, AQL levels range from 0.065 to 6.5. The larger the AQL level, the more lenient the inspection. For general consumer products inspection, AQL level is usually set at 2.5, which implies a zero tolerance for critical defect, 2.5 for major defects, and 4 for minor defects.

What AQL level should I use?

The most common AQL chosen by importers is 2.5% for major defects, 4.0 for minor defects, and 0.1 for critical defects. It is considered the “standard” tolerance for most consumer products sold in supermarkets in North America and in Europe.

How do I select a level in AQL?

There are no guidelines for deciding what AQL limits to choose. You have to decide what your tolerance will be. If the whole batch should not contain more than 1.0% of a certain kind of defect (over the long run), then the AQL should be 1.0% for this kind of defect.
