What are the actions you need to take?
UKIMS Implementation: From March 24th, 2024, each declaration must feature the company's UKIMS authorization code, ensuring compliance with NI trade regulations.
Streamlining Declarations: If you are using it, update your TSS portal with company details and the UKIMS authorization reference to automate the addition of the reference number to each NIREM declaration, simplifying the process.
Avoiding Supplementary Declarations: By September, businesses using this method will eliminate supplementary declarations for goods declared as NIREMS through UKIMS, streamlining operations and minimizing administrative burdens.
EORI Number Alignment: Verify that the EORI number used for UKIMS matches the one in your TSS portal to prevent declaration rejections and ensure seamless transactions.
Conclusions
Navigating the complexities of NI trade regulations demands vigilance and proactive measures to maintain compliance. Adhering to UKIMS requirements and aligning EORI numbers are critical steps in ensuring smooth operations and avoiding potential penalties.
