This page hosts our two trader tools; these are tools to help you establish what declarations are required for your goods movement and how to complete these declarations.

Please select either of these assistant tools to open a new page with the tool, and follow the instructions.

Trader Journey Assistant

The Trader Journey Assistant will ask you a series of questions to determine which declarations are relevant on your journey, and indicate guidance which you may find helpful to complete these declarations. Once you have completed the questions, you will be brought to a personalised output page, which you can bookmark for future reference.

Supplementary Declaration Assistant

The Supplementary Declaration Assistant will help you complete your Supplementary Declaration, providing you with additional guidance on how to input the information required into the Trader Support Service (TSS) portal. Note: this tool can be used for goods movements from Great Britain to Northern Ireland created on the TSS Portal prior to 1 January 2022.

Assisted Completion guide

This guide describes the new Assisted Completion Service. This Service provides additional support for submitting Supplementary Declarations on TSS.
