The World Customs Organization (WCO) Council has formally endorsed the proposal enhanced Harmonized System Framework project.
The WCO Council is the governing body of the WTO, comprised of the heads of 186 Customs administrations.
Over the years, the Harmonized System (HS) has become a universal language for identifying and coding merchandise being traded worldwide. Almost all the world’s economies use it as a basis for their Customs tariffs and for the collection of trade statistics.
While it is updated regularly, WCO members have been discussing the relevance and feasibility of a deeper revision. The project will transform the discussions into a series of practical proposals to improve the clarity and user friendliness of the System for both Customs and the business community.
The major outcomes of the project are expected to be the development of new tools and procedures for use in the HS review cycles and the submission of proposals for changes to its existing provisions.
The HS Contracting Parties, through the Harmonized System Committee, will consider all proposals, and decide on whether the proposals and changes will be adopted.
The project stems from the final report of the “Exploratory Study on a Possible Strategic Review of the Harmonized System” which was submitted to the Council in June, last year.
The WCO Secretariat established a project team tasked with collecting views and suggestions from stakeholders, studying the health of the system, and reporting to the WCO’s members on the possibilities for potential improvements to the HS.
The project is set to start in the fourth quarter of this year and continue over 30 months, finishing in 2028, to ensure that its work can be considered as part of the HS 2033 review cycle.
The Harmonized System came into force in 1988 with the intent to provide greater uniformity for the classification of globally traded commodity groups.
Since its introduction, use has spread globally. As of June 2025, the Convention now has 162 members following the recent addition of El Salvador.
The HS is currently incorporated in the tariff classification schedules of 212 economies. It determines the classification of goods and applicable Customs duties, and is also used to identify goods for a variety of trade facilitation measures, statistical information, and Customs controls.
Since its inception, the HS has been amended seven times to reflect changes in technology and the patterns of global trade.
These amendments have generally focused on the classification of specific classes of goods, while the system as a whole is largely unchanged since 1988.
The core elements of the HS, namely the General Interpretative Rules and the four-digit heading structure, are older as they were taken over, with a few changes, from the predecessor of the HS – the Brussels Nomenclature which came into force in 1959.
Given the changes which have taken place since, it is important to look closely at the underlying aspects of the HS and its tools and how to keep them future-fit.
