Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what estimate he has made of the (a) number of customs declarations which will be made by the 240,000 UK businesses that trade only with the EU and will need to interact with customs processes for the first time in the event that they continue to trade with the EU and (b) average number of those declarations per business.

The customs declaration administrative burden is not available for the 240,000 businesses only. The burden is calculated using a segmentation analysis, to look at the new declarations and costs for five different groups of businesses, differentiated by their trade volumes and use of intermediaries.

This segmentation does not explicitly differentiate EU-only traders, and an estimate is not readily available.
