Ineligible items for prepaid returns
Amazon does not always provide prepaid return shipping labels for auto-authorized returns. Exceptions include the following scenarios:
The customer's address is outside of the U.S.
The seller's return address is outside of the U.S.
For more details about Amazon's international returns policy, see Customer returns for international sales.
Items that weigh more than 150 lbs, have a length greater than 108 inches, or have a length + girth greater than 165 inches. See how to measure length + girth.
Some items classified as dangerous goods.
Note: Amazon will issue prepaid return shipping labels for items containing lithium ion (UN3481) or metal (UN3091) batteries if the customer and seller addresses are located in the contiguous 48 states (and not from Hawaii, Alaska, Puerto Rico, etc.)
When the return is auto-authorized in any of the above scenarios, we will provide the buyer your address, but without postage. We will then send a notification through Manage Returns, for you to complete a manual review at your discretion. Contact the buyer to coordinate the return and issue a refund if appropriate. You can also issue the buyer your own prepaid label at this time.
Important: You must file an exemption for products that should not be auto-authorized. For example, any heavy or bulky items or dangerous goods in your catalog that require special shipping or handling. For details, see Request exemption from automatic return approvals.
