Question to the HM Treasury:

To ask the Chancellor of the Exchequer, with reference to the answer of 29 April 2026 to question 129483, how many (a) individual consignments and parcels were covered by BIRDs declarations under CPC 0020 21V submitted via the Customs Declaration Service and (b) declarations were submitted via the legacy CHIEF system in each year between 2022 and 2025.

The information requested is not available. BIRDs declarations submitted under CPC 0020 21V and declarations submitted via the legacy CHIEF system are aggregated, with a single declaration covering multiple consignments or parcels using a reduced dataset. As a result, the number of individual consignments or parcels is not recorded directly.
