REACH restriction C9-C14PFCAs will be officially implemented on February 25, 2023!


Time:

2023-02-25

The control of C9-C14 PFCAs and their salts and related substances under REACH regulations will be formally implemented on February 25, 2023.

The control of C9-C14 PFCAs and their salts and related substances under REACH regulations will be formally implemented on February 25, 2023. On August 5, 2021, the European Union published (EU) 2021/1297 in its official gazette, revised Annex XVII (Restriction) of REACH, and included C9-C14PFCAs and their salts and related substances in the restriction of REACH regulations as item 68. The main control requirements for C9-C14 PFCAs and their salts and related substances are: from February 25, 2023, the total of C9-C14 PFCAs and their salts in substances, mixtures or articles is less than 25 ppb, The sum of C9-C14 PFCAs related substances is less than 260 ppb.

 

Material information

Straight and branched perfluorocarbonic acids (C9-C14 PFCAs) with molecular formula CnF2n+1 - COOH (n=8,9,10,11,12 or 13), including their salts and any combination thereof;

Any C9-C14PFCA-related substance with a perfluoro group of the formula CnF2n+1 - (n=8,9,10,11,12 or 13) directly connected to another carbon atom, including its salts and any combination thereof;

Any C9-C14PFCA-related substance that has a perfluoro group with the formula CnF2n+1 - (n=9,10,11,12,13 or 14) that is not directly connected to another carbon atom, including its salts and any combination thereof.

 

The following substances do not belong to this category:

- CnF2n+1-X, where X=F, Cl, or Br, n=9,10,11,12,13 or 14, including any combination thereof.

- CnF2n+1-COOX 'where n>13 and X'=any group, including salts.

 

Common uses of substances

Electronic and electrical products and parts, semiconductors, medical devices, textiles, leather, paper products, food packaging, additives, fire foam, cosmetics, sanitary products, coatings, printing ink, paints, adhesives, cleaning agents, polishing agents, snow wax, building materials, etc.

 

Main control requirements

Since February 25, 2023, the total of C9-C14 PFCAs and their salts in substances, mixtures or articles is less than 25 ppb, and the total of C9-C14 PFCAs related substances is less than 260 ppb, otherwise they cannot be manufactured or put on the market.

 

The above requirements are implemented in stages for the following products:

1. From July 4, 2023, it is applicable to: (i) oil-resistant and waterproof textiles, which are used to protect workers from dangerous liquids that endanger their health and safety; (ii) The manufacture of polytetrafluoroethylene (PTFE) and polyvinylidene fluoride (PVDF) for the production of high-performance, corrosion-resistant gas filtration membranes, water filtration membranes and membranes for medical textiles; Industrial waste heat exchanger equipment; Industrial sealant that can prevent the leakage of volatile organic compounds and PM 2.5 particles.

2. From December 31, 2023, it applies to: (a) semiconductor itself; (b) Semiconductors included in semi-finished and finished electronic equipment.

3. From August 25, 2024, the sum of fluoroplastics containing perfluoroalkoxy and fluoroelastomer C9-C14 PFCAs is 2000 ppb. From August 26, 2024, the total concentration limit of C9-C14PFCAs in fluoroplastics containing perfluoroalkoxy and fluoroelastomers should be 100 ppb.

4. From July 4, 2025, it is applicable to: (i) photolithography or etching process in semiconductor manufacturing; (ii) photographic paint applied to film; (iii) Invasive and implantable medical devices; (iv) Liquid fuel vapor suppression and extinguishing foam for liquid fuel fires (Class B fires) that have been installed in the system (including flow and fixed systems), but must meet specific conditions, see the original regulations for details.

5. Applicable to: tank coating of pressurized metered-dose inhalers from August 25, 2028.

6. From December 31, 2030, it is applicable to semiconductors used in spare parts or replacement parts of finished electronic equipment put on the market before December 31, 2023.

 

The following product exemptions

Not applicable to articles put on the market before February 25, 2023.

The limit value of the sum of C9-C14PFCAs and their salts and C9-C14PFCAs related substances in separable intermediates in transportation shall be 10 ppm, and the conditions for manufacturing fluorinated compounds with perfluorocarbon chain length equal to or shorter than 6 atoms in points (a) to (f) of Article 18 (4) of this Regulation shall be met.
The total concentration limit of C9-C14PFCAs in polytetrafluoroethylene powder produced by ionizing radiation or thermal degradation and in industrial and professional mixtures and products containing polytetrafluoroethylene powder shall be 1000 ppb. In addition, C9-C14PFCAs emission should be avoided and reduced during the manufacturing and use of polytetrafluoroethylene powder.
