Key Sentence: The EU’s strictest silicone regulation took effect on June 6, 2026, capping D4/D5/D6 at 0.1% and reshaping global silicone supply chains.

The European Union’s REACH Regulation (EU) 2024/1328 officially entered into force on June 6, 2026, imposing a 0.1% limit on cyclic siloxanes D4, D5, and D6 in all silicone products sold in the EU. Affected categories include electronic potting, textile coatings, mold release agents, and cosmetics. As D4 is classified as a PBT substance, non-compliant goods face customs detention. Chinese exporters are accelerating reformulation, switching to low-volatility raw materials, and updating safety data sheets to maintain EU market access.
