The Nomenclature for the External Trade of Macao/Harmonized System, 7th Revision (NCEM/HS, Rev.7), approved under the Executive Order No. 57/2021, will come into effect on 1 January 2022. This revision is conducted in accordance with the recommendations from the World Customs Organization, and in conformity to the relevant regulations of imports and exports of chemicals under the Chemical Weapons Convention, the Rotterdam Convention, the Stockholm Convention and the International Narcotics Control Board. Moreover, classification of commodities is optimized in line with the operations of the Montreal Protocol and the Basel Convention to strictly regulate greenhouse gases and electronic waste that pollutes the environment. In terms of local context, the revised content aims to meet the needs of social development, such as the implementation of the “Law on Traditional Chinese Pharmacies and Registration of Traditional Chinese Medicines” by the Health Bureau, the regulation of weapons by the Public Security Police Force and the recommendations from the Environmental Protection Bureau for the prevention and reduction of environmental pollution, etc.

With the implementation of NCEM/HS Rev.7, import and export declarations and licenses must be completed in accordance with the new commodity codes.
