The thirty-sixth Revised Kyoto Convention Management Committee (RKC/MC) meeting, held at the World Customs Organization (WCO) in April 2026 marked a watershed by officially adopting the proposed comprehensive amendments to Specific Annex K on Rules of Origin.

This proposal was the result of a process started in 2018 by a sizeable group of sponsoring countries, an international organization, and private sector representatives (The Sponsoring Group of the proposal for Annex K on rules of origin during the ongoing comprehensive review of the Revised Kyoto Convention includes Australia, China, European Union, Japan, New Zealand, Norway, Switzerland, the United Nations Conference on Trade and Development, Eurasian Economic Community, Renault Nissan, Fonterra as of December 2025.) (hereinafter the Sponsoring group) for an updated Annex K on rules of origin of the RKC. While final implementation is still pending in accordance with RKC procedures, the Sponsoring group has nonetheless been able to agree on a plurilateral text on rules of origin – a remarkable achievement.

The absence of multilateral disciplines on rules of origin – the plumbing of international trade in goods – exacerbates compliance costs in trade transactions that are not only continuing but are increasing exponentially in a fractured world trade.

The updated Annex K text provides leverage to resume plurilateral cooperation to enhance transparency and predictability in an area where consensus has proven impossible for decades within both the WCO and the World Trade Organization (WTO).

WCO and WTO secretariats, as well as their respective Members, should reflect on the model, dialogue, and mechanisms adopted by the Sponsoring group to reach consensus on the updated text of Annex K on rules of origin. This experience may offer valuable lessons on how to improve their intergovernmental decision-making machinery.

This article outlines the content of, and the process leading to consensus on the updated Annex K on rules of origin. It further recommends ways and means to leverage this advance in international cooperation as a building block towards the establishment of a plurilateral agreement governing rules of origin and pursue further cooperation in developing guidelines in implementing the updated Annex K.
