FControl of UV-328, a new 31st substance added to POPs in the European Union

Time：

2025-07-16

The EU POPs regulation has been officially revised to include UV-328 in Regulation (EU) 2025/843, bringing the total number of banned substances in the EU to 31.

On July 15, 2025, the Official Journal of the European Union released the officially revised Regulation (EU) 2025/843 on the addition of UV-328 to the EU POPs Regulation. It came into effect on August 4, 2025, the twentieth day after its publication in the Official Journal. As a result, the number of prohibited substances for POPs in the EU has been officially upgraded from 30 to 31.

The main control limit requirements for UV-328 are: the concentration of UV-328 in substances, mixtures, and articles should be ≤ 100mg/kg (August 4, 2025- August 3, 2027), ≤ 10mg/kg (August 4, 2027- August 3, 2029), and ≤ 1mg/kg (starting from August 4, 2029).

(i) If UV-328 was originally used to produce spare parts for civilian and military aircraft, it can continue to be used until December 31, 2030;

3. Articles containing UV-328 that have already been used in the European Union may continue to be used on or before the expiration of the relevant exemptions specified in paragraphs 2 (a) to (i).

Regarding UV-328

UV-328 is a type of ultraviolet absorber widely used in industries such as plastics, coatings, rubber, adhesives, electronic appliances, etc. to improve the UV resistance of materials. Due to its persistence, bioaccumulation, and toxicity (PBT), as well as high persistence and high bioaccumulation (vPvB), UV-328 was identified as a highly concerned substance (SVHC) by the European Chemicals Agency (ECHA) in December 2014.

POPs regulations

Persistent Organic Pollutants (POPs) are a class of natural or synthetic organic pollutants that have long-term residues, bioaccumulation, semi volatility, and high toxicity, and can migrate over long distances through various environmental media (atmosphere, water, organisms, etc.), posing serious hazards to human health and the environment.

The main purpose of POPs regulations is to protect human health and the environment from the hazards of POPs, by reducing their production, use, and emissions, lowering their concentrations in the environment, and thereby reducing potential threats to ecosystems and humans. The regulations also require proper management and disposal of waste containing POPs to prevent secondary pollution to the environment.

Compliance recommendations

In recent years, the EU's POPs regulations have been updated frequently and enforcement efforts have been continuously strengthened. There have also been more and more cases of Chinese products being reported for violating POPs regulations when exporting to the EU. Enterprises should pay timely attention to regulatory developments, respond to adjustment strategies, ensure that products comply with new regulatory requirements, and reduce the risk of violations.
