Definitions of critical/major/minor defects

During onsite visual inspections, we normally classify visual defects into 3 categories according the severities.

Each kinds of defects should be within a set limit according AQL, that is the essence of Final Random Inspection. It is too expensive for do full QC check of the whole shipment again, the factory should have done the inhouse quality QC before packing.

* The clients can define their own defects, and list their own definitions of critical/major/minor defects.

Below is an example of the definition of critical defects, major defects, and minor defects, often used during an quality inspection:

  • Critical – Any condition found which poses the possibility of causing injury or harm to, or otherwise endangering the life or safety of, the end user of the product or others in the immediate vicinity of its use, or in violations of governing government laws, regulations, policies. Or the product is not usable.

  • Major – Any condition found adversely affecting the product's marketability and salability or adversely affecting its required form, fit or function and which is likely to result in the end user returning it to the source from which is was purchased for replacement or refund.

  • Minor – Any condition found which while possibly less than desirable to the end user of the product, does not adversely affect its required marketability, sale-ability, form, fit or function and is unlikely to result in its return to the source from which it was purchased.

Sometimes there is another example, used by some inspectors/buyers for pre-shipment inspection:
