Amazon will end all practices for commingled inventory as of March 31, 2026. Brand owners with registered brand representation can continue to use products with the existing manufacturer barcode without additional labels. Resellers, on the other hand, must use an Amazon label for all products with a manufacturer barcode. This enables Amazon to create more clarity in the supply chain and reduce the risk of counterfeiting.
What do sellers need to be aware of?
Brand representatives receive additional benefits: Brand representatives benefit from the fact that their products will no longer be mixed with goods from other sellers. At the same time, maintaining sufficient stock becomes more important. Lower inventory levels starting April 2026 can reduce delivery speed and impact conversion. Data-driven demand planning will be crucial for stable performance.
Resellers incur higher process costs: In the future, resellers must apply an Amazon barcode to every product or use Amazon’s paid labeling service. This increases unit costs and operational effort. Sellers should analyze how these costs impact their margin and integrate labeling firmly into their processes to remain efficient in the long term.
Brand representatives should check the Brand Registry: Brand representatives should ensure that the Brand Registry is properly maintained and all entries are correct before March 2026. A clear allocation of roles between brand representatives and resellers prevents labeling errors and strengthens supply chain integrity. This allows brands to maintain full control over product standards and assignments.
