What it changes for you

Level and inspection points must be agreed before production; after shipment a defect is a negotiation.

In practice

AQL is the Acceptable Quality Limit, the sampling standard (ISO 2859-1) that defines how many defects are permitted in an inspected lot. It applies when a defect would cost you more than the inspection. The level and the inspection points must be agreed before production, because a defect found after shipment is a negotiation rather than a remedy.

Questions about AQL

Do I need an AQL inspection for a tackle order?

It depends on what a defect costs you. If a returned batch costs more than an inspection man-day, it is cheap insurance. The level and the inspection points have to be agreed before production to be enforceable.

When should the inspection happen?

During production, not only before shipment. Pre-shipment inspection catches problems after the money is spent; a during-production check is where you can still change the outcome.
