TSS Tip: Saving time when completing Supplementary Declarations

Import declarations are required in most cases when you are moving goods from Great Britain to Northern Ireland. It’s the Importer’s responsibility to complete Supplementary Declarations accurately in the timeframe allowed by HMRC (i.e., by the tenth calendar day of the month following the goods movement for TSS simplified movements).

The graphic below shows several ways you can save time when completing Supplementary Declarations:


  1. Refer to the Simplify your customs declarations: group goods under one commodity code guide on NICTA.
  2. Visit the ‘Step-by-step walkthrough of the TSS Supplementary Declaration process’ section of the Supplementary Declarations: Step-by-step guide on NICTA.
