Amazon Compliant Certificates of Analysis (COA)

Many companies are interested in selling their products on online platforms including Amazon. Recently, Amazon has become more strict on verifying that the products sold in their online store comply with Federal and State regulations. With an increase in reviews of the products sold on their market place, many sellers have had their products pulled until they can provide the proper documentation that their products are safe.

Twin Arbor Labs has worked with many online sellers to help them stay compliant with Amazon's policies. Amazon requires that all Food, Dietary supplements, and cosmetics follow the FDA's FD&C act. This requires that products that fall within this act are tested by a third party lab and follow good manufacturing practices (GMPs).
