As a result of the amendment of the CLP Regulation (Regulation (EC) No 1272/2008 on the classification, labelling and packaging of substances and mixtures), new hazard classes have entered into force.
While the process has already started for substances, for manufacturers and importers of mixtures the relevant deadline was 1 May 2026.
The new regulatory approach is structured around three main groups, all of which assess long-term effects on both human health and the environment.
A] Endocrine disruptors (ED)
B] PBT and vPvB substances – Persistent,
Bioaccumulative and Toxic
C] PMT and vPvM substances – Persistent,
Mobile and Toxic
For the new hazard classes, hazard communication in many cases is provided via EUH statements (supplemental hazard statements) and—depending on the overall classification—possibly a signal word (“Danger” / “Warning”).
Updating the classification of mixtures modifies the content of safety data sheets (SDSs) at several points: Section 1, 2, 3, 11 & 12. Special attention should be paid to the consistency of Sections 11 and 12 with the classification (Section 2).
Application deadlines and transitional arrangements:
The most critical point of compliance checking is interpreting the deadlines correctly. The legislator introduced a staged system that distinguishes between substances and mixtures, and between new products and those already on the market.
Substances:
New substances: those first placed on the market after 1 May 2025 must apply the new rules immediately.
Substances already on the market: those already on the market before this date are granted a transitional period until 1 November 2026.
Mixtures:
For mixtures, the deadlines are later, reflecting that reclassification of the constituent substances is a time-consuming process.
New mixtures: those first placed on the market after 1 May 2026 must comply with the new classification rules.
Mixtures already on the market: “on-the-shelf” products may be relabelled and reclassified until 1 May 2028.

Tris(2,4-di-tert-butylphenyl) phosphite (TDPP) often recognized commercially as Irgafos 168 is a high-performance organophosphorus compound primarily utilized as secondary antioxidant and processing stabilizer. Its characteristic to undergo metallation reaction and provide a cost-effective synthetic processes allows it to be useful in biaryl coupling reactions.
Undecylenic acid is an unsaturated fatty acid naturally derived from castor oil. It is a colorless to pale yellow liquid with antifungal and antimicrobial properties. Chemically known as 10-undecenoic acid, it contains an 11-carbon chain with one double bond and is widely used in pharmaceuticals
