The UK Government’s Border Operating Model gave economic operators the option to temporarily make simplified customs declarations via entry into the declarant’s records (EiDR) followed by a supplementary declaration, which would be due 175 days after the arrival of goods in the UK. While the use of this deferred declaration process was extended from July 1, 2021 to January 1, 2022 to give operators more time in light of COVID, the 175-day term remains unchanged. This means that companies that used the EiDR deferred declarations scheme beginning 1 January, 2021 had supplementary declarations due on 25 June.
