This research paper examines how the 2022 amendments to the World Customs Organization's (WCO) Harmonized Commodity Description and Coding System (HS) improve the identification and trade of environmental goods. By introducing more granular six-digit codes for specific technologies, such as solar PV cells and electric vehicles, the amendments reduce the 'specificity problem' in trade negotiations and facilitate the elimination of tariffs on goods essential for climate change mitigation.

• The Harmonized Commodity Description and Coding System (HS), managed by the World Customs Organization (WCO), uses approximately 5,400 six-digit numerical codes to standardize tariffs and trade statistics globally. The HS is reviewed every five years by the HS Review Sub-Committee (RSC) to maintain relevance to world merchandise trade.
• The HS 2022 amendments address the 'specificity problem' by assigning separate six-digit codes to environmental goods that were previously grouped together. For example, solar photovoltaic (PV) cells and modules, which were previously grouped with LEDs under subheading 8541.40, are now split into separate codes: 8541.43 for cells assembled in modules or panels, 8541.42 for those that are not, and 8541.41 for LEDs.
• HS 2022 introduces new classifications for various environmental and climate-related technologies, including fully or partially electrified road tractors for semi-trailers (heading 87.01), non-articulated trucks (heading 87.04), catalytic converters and particulate filters (subheading 8421.32), and mass spectrometers (9027.81).
• More precise HS coding simplifies the process for trade negotiators to nominate environmental goods for tariff elimination, specifically within the six-nation Agreement on Climate Change, Trade and Sustainability (ACCTS). Eliminating these tariffs is described as one of the most cost-effective ways for countries to address climate change.
