Latest EU regulations: REACH Annex XVII adds perfluorohexanoic acid (PFHxA), its salts, and PFHxA-related substances to the list

  • 2025-07-07

Dear Customer, We would like to inform you of an important regulatory change that will have a significant impact on the chemicals and manufacturing industries.

親愛的客戶,我們要告知您一項重要的法規變更,將對化學品和製造業產生重大影響。

On September 19, 2024, the European Union published Regulation (EU) 2024/2462 via EUR-Lex, adding Entry 79 to REACH Annex XVII to regulate the content of PFHxA, its salts, and PFHxA-related substances in textiles, leather, mixtures, and other products.



Entry 79 content:

controlled substances
Perfluorohexanoic acid (PFHxA), its salts and PFHxA-related substances: (a) a linear or branched perfluoropentyl group with the chemical formula C5F11-, directly attached to another carbon atom as one of the structural components; or (b) a linear or branched perfluorohexyl group with the chemical formula C6F13-.

The following substances are not included in this definition: (a) C6F14; (b) C6F13-C(=O)OH, C6F13-C(=O)O-X′ or C6F13-CF2-X′ (where X′ can be any group, including a salt); (c) any substance having a perfluoroalkyl group C6F13- with an oxygen atom directly attached to a non-terminal carbon atom.
Restricted scope
From 10 October 2026, the following articles shall not be placed on the market or used in the market in concentrations equal to or greater than 25 ppb of the sum of PFHxA and its salts, or equal to or greater than 1,000 ppb of the sum of PFHxA-related substances, measured on a homogeneous basis: (a) textiles, leather, fur and hides in clothing and related accessories intended for use by the general public; (b) footwear intended for use by the general public; (c) paper and paperboard intended for food contact within the scope of Regulation (EC) 1935/2004; (d) mixtures intended for use by the general public; (e) cosmetics as defined in Article 2(1)(a) of Regulation (EC) 1223/2009. From October 10, 2027, with the exception of clothing and related accessories intended for general public use as mentioned in paragraph 1, the following articles shall not be placed on the market or used in articles containing PFHxA and its salts at a concentration equal to or greater than 25 ppb, or PFHxA-related substances at a concentration equal to or greater than 1,000 ppb, measured in a homogeneous material: textiles, leather, fur, and hides. For the purposes of this entry, PFHxA-related substances are substances that, based on their molecular structure, have the potential to degrade or transform into PFHxA.
