On January 10, 2018, the United Kingdom (UK) issued guidance on Trade Tariff: Correlation Tables indicating changes to the combined nomenclature for 2018.
The guidance contains tables that show the proposed combined nomenclature for 2018 and the tariff classification codes for 2017 that the 2018 codes will replace.
The European Union seeks to minimize commodity code changes currently undergoing review for revision in 2018; therefor, the code changes for 2018 include a low number of changes. Additionally, the World Customs Organization have started planning and reviewing for the changes for 2018.
