On May 5, 2025, the European Commission approved an authorization regulation C(2025)2567, proposing to add control requirements for UV-328 in Part A of Annex I of the EU POPs Regulation. The European Commission published the amendment to the POPs Regulation — (EU) 2025/843 — in its Official Journal on July 15, 2025, officially listing UV328 in the EU POPs Regulation’s list of banned substances. With this, the list of banned substances in Annex I of the EU POPs Regulation has officially been expanded from 30 to 31 items. A new entry for UV-328 has been added to Part A of Annex I.
Substance | CAS No | EC No | Specific exemption on intermediate use or other specification |
‘2-(2H-benzotriazol-2-yl)-4,6-di-tert-pentylphenol (UV-328) | 25973-55-1 | 247-384-8 | 1. For the purposes of this entry, Article 4(1), point (b), shall apply to concentrations of UV-328 equal to or below: (a) 100 mg/kg (0,01 % by weight) from 4 August 2025; (b) 10 mg/kg (0,001 % by weight) from 4 August 2027; (c) 1 mg/kg (0,0001 % by weight) from 4 August 2029; where they are present in substances, mixtures or articles. 2. By way of derogation, the placing on the market of UV-328 present in articles and the use of such articles shall be allowed for the following purposes: (a) in land-based motor vehicles, until 4 August 2030; (b) in industrial coating for land-based motor vehicles, engineering machines, rail transportation vehicles, and in heavy-duty coatings for large steel structures, until 4 August 2030; (c) in mechanical separators in blood collection tubes, until 4 August 2030; (d) in triacetyl cellulose film in polarisers, until 4 August 2030; (e) in photographic paper, until 4 August 2030; (f) in civilian and military aircrafts, until 4 August 2030; (g) in spare parts for any of the following: (i) land-based motor vehicles; (ii) stationary industrial machines for use in agriculture, forestry and construction; (iii) liquid crystal displays in instruments for analysis, measurements, control, monitoring, testing, production and inspection, other than for medical applications; where UV-328 was initially used in their production, until the end of their service life or 31 December 2043, whichever comes earlier; (h) in spare parts for any of the following: (i) liquid crystal displays in devices within the scope of Regulation (EU) 2017/745, and within the scope of Regulation (EU) 2017/746 of the European Parliament and of the Council (*1);

CIRS Reminder
UV-328 is a widely used ultraviolet light absorber in plastics, coatings, and cosmetics, effectively preventing material degradation due to UV exposure. CIRS Testing advises companies exporting to Europe to verify the content of UV-328 in their products to avoid non-compliance and potential losses.
