Article 33 Communication

Article 33 of REACH requires suppliers of articles containing Candidate List SVHCs above 0.1% weight by weight (w/w) to provide sufficient information to allow the safe use of the article to professional recipients automatically, and to consumers within 45 days of request, free of charge. At minimum, the SVHC name must be communicated. This obligation arises immediately upon a substance’s inclusion in the Candidate List, regardless of tonnage. As of February 4, 2026, the Candidate List contains 253 entries.

REACH Regulation (EC) No 1907/2006, Article 33; ECHA Guidance on Substances in Articles.

Article 33 requires an active, documented communication system. Every time ECHA updates the Candidate List (typically biannually in January and June, plus occasional interim updates), companies must screen their entire article portfolio against the new entries and notify customers within 45 days for consumer-facing articles. Non-compliance with Article 33 is directly enforceable by Member State authorities and is a common source of supply chain disruption.
