AQL quality control in China: practical guide

Understand AQL sampling, its limits and how it fits into a pre-shipment inspection.

Good sourcing starts with comparable information. The clearer the product brief, the easier it becomes to compare suppliers on more than factory price alone.

What AQL measures

Good sourcing starts with comparable information. The clearer the product brief, the easier it becomes to compare suppliers on more than factory price alone.

The decision should include MOQ, lead time, capacity, available documents, target quality, packaging and logistics cost. A weakness in one area can cancel out an attractive factory quote.

Inspection levels

The decision should include MOQ, lead time, capacity, available documents, target quality, packaging and logistics cost. A weakness in one area can cancel out an attractive factory quote.

Samples and pre-production approvals then become operational references. Critical criteria should be written, measurable and reusable during quality control.

Critical, major and minor defects

Samples and pre-production approvals then become operational references. Critical criteria should be written, measurable and reusable during quality control.
