HMRC System Scheduled Unavailability – The Introduction of NCTS5 Final State Rules
Historic - 22:00, January 20th - 00:15, January 21st
Sequoia will automatically switch from Transitional State to Final State rules at midnight between 20th and 21st January.
However, as the HMRC system is unavailable between 22:00 on 20th and 00:15 on 21st January, you should not submit declarations or arrivals between these times.
HMRC will issue communications and update the service availability page to confirm when each service has successfully gone live. You are advised to check before resuming transit operations.
