The Customs (Tariff and Miscellaneous Amendments) (No. 3) Regulations 2025, effective October 29, 2025, update several UK Customs regulations.
These amendments revise version numbers in documents pertaining to import duty rates, authorized use procedures, and the Tariff of the United Kingdom.
The changes aim to improve accuracy, streamline processes, and maintain alignment with international agreements.
The regulations were developed with consideration of recommendations from the Secretary of State and relevant international arrangements.
Arguments For
Improved accuracy and consistency: The amendments update referenced documents, correcting errors and aligning them with current practices, ensuring the consistent and accurate application of import duty rates and authorised use procedures.
Streamlined processes: Updated document versions aim to simplify customs procedures by clarifying definitions and removing outdated or erroneous information, making compliance easier for businesses.
Alignment with international agreements: The regulations consider international agreements relevant to customs procedures, demonstrating commitment to global trade standards and harmonization of practices.
Legal basis: The regulations are enacted under the powers conferred by the Taxation (Cross-border Trade) Act 2018, providing a solid legal foundation for the changes.
Transparency and Public Notification: The changes and their rationale are clearly explained in the Explanatory Note and are publicly available online. This ensures transparency and allows stakeholders to understand the implications of the updates.
Arguments Against
Administrative burden: Frequent updates to reference documents may create an administrative burden on businesses that need to keep abreast of changes and update their systems accordingly.
Potential for unintended consequences: While aiming to improve accuracy, any changes could potentially introduce unforeseen issues in the application of import duty rates or the management of authorized use procedures.
Resource allocation: Implementing and communicating these updates requires resources from government agencies and businesses involved in import/export operations.
Lack of impact assessment for this specific instrument: While an overarching assessment existed for previous legislation, a specific impact assessment was not provided for these amendments. This could limit understanding of their specific effects.

Explanatory Note
(This note is not part of the Regulations)
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 removes one commodity code to align with changes made to the “Tariff of the United Kingdom” reference document.
Regulation 3 amends the definition of the “Tariff of the United Kingdom” document in regulation 1(2) of the Customs Tariff (Establishment) (EU Exit) Regulations 2020 (S.I. 2020/1430) to refer to a new version of that document. The new version of that document includes an additional Chapter note and decreases the import duty rate on the commodity code related to “beans, other” from 18% to 16%. It also rectifies errors by removing incorrect reference to authorised use measures from 79 commodity codes and replacing them with a standard rate of 0%.
Regulation 4 amends the definition of “authorised use rates document” in regulation 20(4) of the Customs (Reliefs from a Liability to Import Duty and Miscellaneous Amendments) (EU Exit) Regulations 2020 (S.I. 2020/1431) to refer to a new version of that document. The new version of this document will include an additional subheading for the authorised use procedure relating to “Parts, Components and Subassemblies of Weapons and Military Equipment”.
Regulation 5 amends the definition of “Suspensions of Import Duty Rates Document” in regulation 2 of the Customs Tariff (Suspension of Import Duty Rates) (EU Exit) Regulations 2020 (S.I. 2020/1435) to refer to a new version of that document. The new version of that document makes technical changes to the commodity codes listed.
By virtue of section 32A of the Taxation (Cross-border Trade) Act 2018 (“the Act”) (as inserted by section 75 of the Finance Act 2022 (c. 3)), where regulations made under any of sections 8 to 19 of the Act make provision by reference to a document, this is a reference to the document as modified from time to time, or as replaced, by notice by the appropriate authority: https://www.gov.uk/government/publications/notices-made-under-s32a-of-the-taxation-cross-border-trade-act-2018. As updates have been made to the documents referred to in the provisions of this instrument by notice under section 32A of the Act, the version number updates appear as non-sequential in this instrument.
An Impact Assessment has not been prepared for this instrument as it largely maintains the position of existing legislation, which were covered by an overarching Tax Information and Impact Note published in 2021: https://www.gov.uk/government/collections/tax-information-and-impact-notes-tiins.
This explanatory note summarizes the changes made by each regulation.
Regulation 2 updates an authorized use document, Regulation 3 updates the UK Tariff document (including a duty rate change for beans), Regulation 4 updates an authorized use rates document to include military equipment, and Regulation 5 updates a document on import duty rate suspensions.
Section 32A of the Taxation (Cross-border Trade) Act 2018 allows for document updates via notice. No new impact assessment was conducted, as existing legislation covered this.
