The supplementary declaration is the final step in the import process and one that you are legally required to complete.
If you moved goods between 1 January and 14 February, you will start receiving emails from TSS over the next month informing that you have supplementary declarations to complete.
If you moved goods between 1- 6 January you have been notified by email that you can now complete your supplementary declarations. The final completion date for these is 1 May as covered above.
If you require support with these supplementary declarations please contact us via the TSS portal here or call us on 0800 060 8888 from 7:30am to 10:30pm seven days a week.
