EU Announcement – ​​New RoHS Annex III Item 9(a)-III Exclusion Clause

  • 2025-07-14

The study evaluating the RoHS exemption application concluded that replacing hexavalent chromium in refrigerant solutions is currently not scientifically and technically feasible, while other heating technologies that eliminate hexavalent chromium in the form of sodium chromate do not provide equivalent functionality and performance. Gas absorption heat pumps do offer higher energy efficiency than condensing boiler technology and can reduce carbon emissions, meeting the exemption conditions under Article 5 of the EU RoHS Directive 2011/65/EU. Therefore, new exemption clauses 9(a)-III for hexavalent chromium have been added to Annex III of the directive.

針對RoHS 豁免申請評估的研究結論,製冷劑溶液中替代六價鉻目前在科學和技術上是不可行的,而其他消除了鉻酸鈉形式的六價鉻使用的加熱技術並不能提供同等的功能和性能,氣體吸收式熱泵確實可以提供比冷凝鍋爐技術更高的能源效率,並可以減少碳排,符合歐盟RoHS指令2011/65/EU Article 5 豁免條件,因此在指令的附錄 Ⅲ 中新增關於六價鉻的豁免條款9(a)-Ⅲ

On January 26, 2023, the Official Journal of the European Union officially published Commission Delegated Directive (EU) 2023/171, which added exclusion clauses 9(a)-III of Annex III to the RoHS Directive (2011/65/EU). This update will take effect on the 20th day after the announcement.

EU member states should adjust the relevant laws and regulations and announce them before August 31, 2023, and they should be officially implemented on September 1, 2023.

The new content is as follows:

ExemptionsApplication scope and date
9(a)-IIIHexavalent chromium as a corrosion inhibitor in the working fluid of carbon steel seal circuits of gas absorption heat pumps for space and water heating, up to 0.7% by weight of the cooling solutionApplicable to Category 1
Expires on December 31, 2026
