Regulation 2 amends the definition of “the authorised use document” in regulation 32(2) of the Customs (Special Procedures and Outward Processing) (EU Exit) Regulations 2018 (S.I. 2018/1249) to refer to a new version of that document. The new version of this document makes amendments to align with EU commodity code updates. It will also introduce authorised use measures to reduce import duty on goods that will be used to manufacture offshore wind turbines, including cables that link the wind farm to the mainland substations and auxiliary and low-voltage systems for incorporation in onshore substations and offshore substations used in offshore wind energy production.
