Introduction
In the European Union, according to Regulation (EU) 2019/1021 on persistent organic pollutants (POP),
Article 3, Clause 1, in connection with Annex I, amended by Commission Delegated Regulation
(EU) 2020/784, the manufacturing, placing on the market and use of perfluorooctanoic acid (PFOA), its
salts and PFOA-related compounds, whether on their own, in mixtures or in articles, is prohibited. This
is in addition to the existing prohibition of perfluorooctane sulfonic acid and its derivatives (PFOS).
According to Article 4 Clause 1. (b) this does not apply in the case of a substance present as an
unintentional trace contaminant, as specified in the relevant entries of Annex I in substances, mixtures
or articles.
Annex I Part A, describing perfluorooctane sulfonic acid and its derivatives (PFOS), contains the specific
exemption (Point 2) to concentrations of PFOS in semi-finished products or articles, or parts thereof, if
the concentration of PFOS is lower than 0,1 % mass fraction calculated with reference to the mass of
structurally or micro-structurally distinct parts that contain PFOS or, for textiles or other coated
materials, if the amount of PFOS is lower than 1 μg/m of the coated material. PFOS compounds have the
+
formula C F SO X where X = OH, Metal salt (O-M ), halide, amide and other derivatives, including
8 17 2
polymers.
In Annex I Part A, describing perfluorooctanoic acid (PFOA), its salts and PFOA-related compounds,
contains the specific exemption (Point 1) to concentrations of PFOA or any of its salts equal to or below
0,025 mg/kg (0,000 002 5 % mass fraction), where they are present in substances, mixtures or articles.
In addition, (Point 2) Article 4(1) applies to concentrations of any individual PFOA-related compound or
a combination of PFOA-related compounds equal to or below 1 mg/kg (0,000 1 % mass fraction) where
they are present in substances, mixtures or articles.
PFOA, its salts and PFOA-related compounds means the following:
i) perfluorooctanoic acid, including any of its branched isomers;
ii) its salts;
iii) PFOA-related compounds which, for the purposes of the Convention, are any substances that degrade
to PFOA, including any substances (including salts and polymers) having a linear or branched
perfluoroheptyl group with the moiety (C F )C as one of the structural elements.
7 15
The following compounds are not included as PFOA-related compounds:
iv) C F -X, where X = F, Cl, Br;
8 17
v) fluoropolymers that are covered by CF [CF ] -R’, where R’ = any group, n > 16;
3 2 n
vi) perfluoroalkyl carboxylic acids (including their salts, esters, halides and anhydrides) with ≥ 8
perfluorinated carbons;
vii) perfluoroalkane sulfonic acids and perfluoro phosphonic acids (including their salts, esters, halides
and anhydrides) with ≥ 9 perfluorinated carbons;
viii) perfluorooctane sulfonic acid and its derivatives (PFOS), as listed in Annex I.
As a further exemption in Annex I Part A (Point 5 c) the manufacturing, placing on the market and use of
PFOA, its salts and PFOA-related compounds is allowed in textiles for oil and water repellency for the
protection of workers from dangerous liquids that comprise risks to their health and safety, until 4 July
2023.
Commission Regulation (EU) 2021/1297 amending Regulation (EC) No 1907/2006 (REACH), Annex
XVII [7] restricts perfluorocarboxylic acids containing 9 to 14 carbon atoms in the chain (C9-C14 PFCAs),
their salts and C9-C14 PFCA-related substances from 25 February 2023.
This restriction concerns the following substances:
Linear and branched perfluorocarboxylic acids of the formula C F -C(= O)OH where n = 8, 9, 10, 11,
n 2n+1
12, or 13 (C9-C14 PFCAs), including their salts, and any combinations thereof;
Any C9-C14 PFCA-related substance having a perfluoro group with the formula C F - directly attached
n 2n+1
to another carbon atom, where n = 8, 9, 10, 11, 12, or 13, including their salts and any combinations
thereof;
Any C9-C14 PFCA-related substance having a perfluoro group with the formula C F - that it is not
n 2n+1
directly attached to another carbon atom, where n = 9, 10, 11, 12, 13 or 14 as one of the structural
elements, including their salts and any combinations thereof.
The following substances are excluded from this designation:
C F -X, where X = F, Cl, or Br
n 2n+1
where n = 9, 10, 11, 12, 13 or 14, including any combinations thereof,
C F -C(= O)OX' where n > 13 and X' = any group, including salts.
n 2n+1
Several per- and poly-fluorinated alkylated substances (PFAS), which are not restricted under the POP
Regulation have been added as Substances of Very High Concern (SVHC) to the Candidate List according
to Regulation (E
