Get to Know Certificate of Analysis

Certificate of Analysis (COA) is a document issued by Quality Assurance to confirm that a regulated item meets its quality specifications. With countless items being produced by manufacturers, it is often difficult for a company to seamlessly track materials quality used in the production. This means that companies rely more and more on their suppliers to provide quality materials for finished products.

A COA goes beyond a mere identity for product inspection as well. With materials rapidly moving to and from different locations, it is necessary to have the products to be correctly identified and clarified. In addition to material and container labels, the COA serves as an identification document for the status of each product. A COA includes the inspection results from the quality control tests for an individual item batch or lot.


In NetSuite, COA is available only for quality inspections with a Sampling Requirement set to Simple Sampling. NetSuite COA is included as a support for lot controlled items only.
