As of 1 July 2026, the European Commission introduced two amendments via Commission Implementing Regulation 2026/1422 that modify the Union Customs Code Implementing Regulation (UCC‑IA). These changes aim to streamline the procedural rules for proving the origin of goods that do not qualify for preferential treatment. The amendments introduce clearer documentation requirements, enable electronic submission of origin proofs, and establish defined timelines for verification by customs authorities. By simplifying the verification process, the Commission seeks to reduce administrative burdens, lower compliance costs, and improve the overall efficiency of the EU customs union. The reforms also include transitional measures for businesses previously registered under the existing system, ensuring a smooth shift to the new procedures. This initiative is part of a broader effort to modernise customs processes, support small and medium‑sized enterprises, and enhance security while facilitating legitimate trade across all member states.
