Question to the HM Treasury:

To ask Her Majesty's Government what plans they have to help (1) reduce, or (2) remove, the costs of carnets for those working in the fashion industry who travel to Europe for work purposes.

This question was answered on 3rd December 2021
In the UK, ATA Carnets are administered by the London Chamber of Commerce and Industry. More information can be found on their website.

As an alternative to an ATA carnet, businesses and individuals may be able to use the EU’s Temporary Admission procedure, when moving goods temporarily into the EU. The EU’s Temporary Admission procedure allows goods to enter the EU on a temporary basis without payment of duties subject to relevant conditions being met. Temporary Admission rules allow a customs declaration to be made orally or by conduct, by speaking to a customs official or driving through the green channel at port, in certain circumstances. This may be a cost-effective option for eligible businesses and individuals. The management of EU import and export procedures is the responsibility of the customs authorities of the Member States, so it is important that businesses and individuals confirm any conditions or procedures that may apply, such as the time limit that goods may remain in the EU without the payment of duty. Further information can be found on the EU’s website.
