These Regulations amend the Customs Transit Procedures (EU) Exit Regulations 2018 (S.I. 2018/1258) and related Regulations. In particular, they authorise HM Revenue and Customs to set out in a public notice the locations where pre-notification of customs transit documents will be required. They also allow for the use of guarantees authorised by overseas customs authorities in relation to customs transit procedures, and for customs fees to be charged and payable as set out in a notice
