HMRC published\u00a0Statutory Instrument 2026\/253\u00a0on 3 March 2026, introducing five significant changes to the UK’s customs tariff regime. From Ukraine trade liberalisation to offshore wind duty relief, these updates affect importers, exporters, customs agents, and logistics operators across multiple sectors \u2014 and take effect immediately.<\/strong><\/p>\n

[\/vc_column_text][vc_column_text]<\/p>\n

What Has Changed and Why It Matters<\/strong><\/h3>\n

The March 2026 tariff update is one of the most substantively varied statutory instruments published this year. It spans five distinct changes \u2014 extending a trade liberalisation arrangement supporting Ukraine, updating annual tariff rates under the UK\u2013Japan CEPA, introducing new duty relief for the offshore wind energy sector, and correcting technical errors affecting Iceland\u2013Norway and North Macedonia trade references. Together, these changes affect a broad cross-section of UK trade activity.<\/p>\n

Understanding which changes apply to your business \u2014 and acting on them correctly \u2014 is essential to claiming the right preferential rates, avoiding unnecessary duty costs, and maintaining compliant customs declarations from 3 March 2026 onwards.<\/p>\n

UK\u2013Ukraine Trade Liberalisation Extended to 2028<\/strong><\/h3>\n

The preferential tariff reference document for Ukraine has been updated to give effect to the temporary liberalisation of tariffs on imports of Ukrainian egg and poultry products. This extension runs until\u00a031 March 2028<\/strong>, building on the agreement between the UK and Ukraine to support Ukrainian agricultural exports during the ongoing conflict.<\/p>\n

The measure provides zero or reduced tariffs on specified egg and poultry product lines, and represents a continuation of the UK’s post-Brexit trade support arrangements with Ukraine. The two-year extension \u2014 beyond the previous temporary measures \u2014 provides a meaningful forward planning horizon for importers operating in these categories.<\/p>\n

          Offshore Wind Energy: New Authorised Use Duty Relief<\/strong><\/h3>\n

          This is the most strategically significant of the five changes in SI 2026\/253. New\u00a0authorised use measures<\/strong>\u00a0have been introduced to reduce import duty on goods used in the manufacture of offshore wind turbines. The measure is implemented through amendments to the Customs (Special Procedures and Outward Processing) (EU Exit) Regulations 2018 and a new version of the “Authorised Use: Eligible Goods and Rates” document (version 1.23, dated 3 March 2026).<\/p>\n

          The policy reflects the UK’s broader commitment to offshore wind expansion and Net Zero objectives, reducing the import cost burden on businesses supplying components into the renewable energy supply chain.<\/p>\n

          \n

          To benefit from this relief, importers must use the Authorised Use special procedure<\/strong>. This requires prior authorisation from HMRC and the goods must be used for the specified eligible purpose. The updated Authorised Use document (v1.23) specifies the eligible goods and their reduced duty rates. The update also aligns commodity codes with recent EU code changes.<\/p>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

          Iceland\u2013Norway and North Macedonia: Technical Corrections<\/strong><\/h3>\n

          The preferential tariff reference document for Iceland and Norway has been updated to\u00a0correct technical errors<\/strong>\u00a0identified in the previous version. Operators importing from these countries should ensure they are working from the updated document to avoid applying incorrect rates or conditions.<\/p>\n

          Separately, the origin reference document for\u00a0North Macedonia<\/strong>\u00a0has been updated to give effect to the latest decisions under the UK\u2013North Macedonia Partnership, Trade and Cooperation Agreement. Importers and exporters trading under this agreement should verify their origin documentation and declaration data against the updated reference.<\/p>\n

          \u00a0<\/td>\n\n
          \ud83d\udccc Practical Note<\/div>\n
          \n

          Technical corrections of this kind are easy to overlook, but applying outdated or erroneous tariff data \u2014 even where the source of error is HMRC’s original document \u2014 can result in incorrect duty calculations and post-clearance queries. Always work from the current version of the relevant reference document<\/strong>, as published in the UK Integrated Tariff.<\/p>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
