New substance restrictions under EU REACH Annex XVII took effect in May 2026, imposing tighter controls over phthalates and fluorinated surfactants widely used in PCB adhesives, coatings and substrate materials. The updated rules require full supply chain traceability and compliance documentation for circuit boards entering the EU market. Non-compliant shipments risk customs detention and fines. Electronics exporters must upgrade material testing, audit raw material suppliers and update BOM records to meet the new chemical reporting requirements.
