Hi @Seller_JOmqU2JUa2orr,

Michelle from the Community Manager team here. You are correct, anytime that a product has been updated, it would need a new UPC. You can find the policy below and the full policy here.

Policies for editing detail pages

You may only update detail pages to better or more accurately describe the product as originally listed. For example, permissible updates include additional details, clarifications, grammatical fixes, or removal of content that violates Amazon policy.

You must not use an existing listing for a new version of a product. This includes changes in color, size, material, features, and product name. Instead, create a new product detail page for each new version. For example, a manufacturer updates its streaming media player by adding a new remote control with four buttons instead of two. This product is materially different from the older version and it must be listed as a new ASIN.

If you choose to re-brand a product you must create a new ASIN rather than update an existing ASIN. This is true even if the product is unbranded and does not change materially after the brand change. This includes adding a brand to a previously unbranded product.

I hope you find this information helpful. Feel free to reach out if you need further assistance.

Regards,

Michelle
