What quality standards do we use for product inspections?

Based on the acceptable quality limit sampling size chosen from the AQL tables we carefully ensure to select production samples randomly. We inspect the samples and classify the defects into critical, major and minor defects. We use detailed product checklists for these definitions - our clients are invited to make amendments.
According to the number of defects found for each type, we will advise you to accept or to reject your shipment.

Then you make your own decision based on the detailed report we have provided to you so you can discuss the findings with your vendor ask him to rework/re-produce/sort out the defective products.
