The new safety standards for dietary supplements sold on Amazon US require sellers to conduct more research and testing on their products. They must ensure that their products are verified through a Third-Party Testing, Inspection, and Certification (TIC) organization. This verification process is to confirm that the products meet Amazon's safety and labeling standards.

To initiate testing for dietary supplements on Amazon, sellers need to navigate to their Manage Your Compliance dashboard. From there, they can start the testing process for each affected product. Sellers will then work directly with the chosen TIC organization to complete the testing process. It's important to act promptly as listings may be removed if they are found to be non-compliant by the specified due date.

Once a product passes the third-party testing, Amazon will directly confirm with the TIC organization that the seller's compliance is in check. After this verification, the product will be eligible for sale on Amazon.

Failing to comply with Amazon's new dietary supplement regulations can result in the product being removed from the platform. Appealing the removal is a lengthy process; previously, it took around two and a half months to start selling again due to the tedious manual review process.

The new Amazon regulations will increase the cost of launching dietary supplements because sellers are now required to conduct thorough research and testing, and work with verified TIC organizations. These additional measures create a higher barrier to entry due to the increased costs associated with ensuring compliance.
