Category of Items: June 2026 changes
Mailcoms Support · International Post
The customs declaration and Category of Items changes coming into effect from 1 June 2026, including B2B, B2C and the move to CN23.
Important updates to customs declarations and category of items from 1st June 2026
At present, all international postal items of commercial value require the completion of a CN22 or CN23 form, alongside the provision of electronic customs data. This information is used to generate the customs declaration for your shipment.
However from 1st June 2026, the following changes will be introduced:
- A legislative update will affect how the ‘Category of Items‘ is selected for international shipments. The existing ‘Sale of Goods‘ category will be divided into two distinct options:
- B2B (Commercial sale of goods): Transactions involving the sale of goods from your business to an overseas business.
- B2C (eCommerce goods): Transactions involving the sale of goods from your business directly to an overseas customer
- To simplify the selection process, the ‘Mixed‘ category will be removed.
- Additionally, we will standardise the use of the CN23 customs declaration form across all of our postal services and shipping solutions. The CN22 form will no longer be used or available for selection, except in cases where combined labels are selected, where CN22 will still apply.
