Launch Announcement: Addition of non-conveyable surcharge in Amazon Shipping APIs

The purpose of this announcement is to notify shipping integrators of a change to the Amazon Shipping API, displaying the surcharge for UK shippers for non-conveyable shipments.

What's New?

We are improving pricing transparency by displaying non-conveyable surcharges upfront during label creation, rather than only on shippers’ invoice. The surcharge amount will remain as specified on each shipper’s Shipping rates page within their Amazon Shipping account.
For details about what qualifies as non-conveyable, please consult the Amazon Shipping Service Guide.

Note: This new display feature helps you better anticipate total shipping costs at the time of label purchase.

Key Features:

Naming Convention Update: Change ADDITIONAL_HANDLING_SURCHARGE to NON_CONVEYABLE_SURCHARGE
Expected Launch Date: August 11, 2025; Marketplace affected: UK.

How It Works:

The new AdditionalPackageInfo array has been added to the main package object in the API. This allows you to specify the PO number for each package:

SchemaExample

 "additionalPackageInfo": {  
      "type": "array",  
      "description": "Additional information about the package provided by Shipper",  
      "items": {  
        "type": "object",  
        "required": ["name", "value"],  
        "properties": {  
          "name": {  
            "type": "string",  
            "description": "The name of the information content being sent along with the package",  
            "enum": [  
              "PURCHASE_ORDER_NUMBER"  
            ],  
            "x-docgen-enum-table-extension": [  
              {  
                "value": "PURCHASE_ORDER_NUMBER",  
                "description": "Specifies the Purchase Order number."  
              }  
            ]  
          },  
          "value": {  
            "type": "string",  
            "description": "The value of the information content being sent along with the package"  
          }  
        }  
      }  
    }

How It Works:

A new value (NON_CONVEYABLE_SURCHARGE) has been added to the RateItemID Enum which is used in the rateItemList field of the Rate object. This will be used to describe new RateItem Charges.
