Thousands Amazon Sellers Face Listing Deactivations Due to Third-Party GMP Verification Requirements

SAN DIEGO - EntSun -- Amazon sellers across multiple high-risk categories are facing a growing and alarming threat: sudden product listing deactivations triggered by GMP (Good Manufacturing Practices) verification conducted by third-party auditors. As Amazon tightens compliance standards, thousands of businesses are seeing their revenue halted overnight — often without clear instructions or warning.

Amazon is Cracking Down all the Supplement Sellers in 2026

Amazon has significantly increased its reliance on independent third-party compliance providers to verify whether products meet GMP standards. This new policy will affect sellers in supplements, health products, cosmetics, personal care, food, and children toys categories. When verification fails — or documentation is deemed insufficient — Amazon immediately deactivates listings.

For many sellers, the impact is devastating.

A single deactivated ASIN can instantly stop sales, cancel advertising campaigns, destroy organic rankings, and damage account health metrics that take months or years to rebuild.

AMZing Marketing Agency warns that GMP deactivation is no longer a rare compliance issue — it is a business-ending event for unprepared sellers.

"Amazon is no longer asking sellers to simply upload documents," said a compliance specialist at AMZing Marketing. "They are evaluating credibility, traceability, and regulatory understanding. One wrong submission can cost a seller their listing forever."

Many sellers make critical mistakes during this process. Some rush to submit incomplete certificates. Others rely on generic appeal templates that fail to address third-party audit concerns. Emotional or defensive responses often worsen the situation, leading to repeated rejections and long-term account damage.

AMZing Marketing, a Canadian-based Amazon marketing and compliance agency founded over 10 years ago, is stepping in to help sellers navigate GMP-related deactivations with precision and strategy.

"Amazon doesn't give unlimited chances," AMZing Agency emphasized. "Every appeal matters. Our job is to make sure sellers get it right the first time."

AMZing Marketing urges affected sellers to seek professional guidance before submitting additional responses to Amazon.

For sellers facing GMP verification issues, the message is clear: act fast, act strategically, or risk losing your Amazon business entirely.
