I had by mistake applied wrong Carton labels on some boxes

The shipment is already dispatched.

Will Amazon reject those boxes or they will check on their end and increase the processing time correcting the cartons?

Thank you

Amazon may reject the boxes if the labels don’t match the contents, as it could cause confusion during the fulfillment process. It’s best to contact Amazon Seller Support immediately to explain the situation and see if they can assist in resolving the issue. They may be able to update the information on their end or provide guidance on how to proceed.

Don’t worry, when your inventory will reach at wearhouse then Amazon will try to identify your cartons if they got a mistake from your end, then you can open a case and explain your mistake then amazon will charge some fee for set your labels!

Amazon will likely reject the boxes with incorrect carton labels as they need to ensure accurate tracking and inventory management. It’s best to contact Amazon Seller Support as soon as possible to discuss the issue and explore potential solutions.

Amazon will accept your product. They will identify the products by themselves and will charge a penalty fee so you don’t need to worry about it.
