Quick answer: On 4 February 2026, ECHA added n-hexane and 4,4′-[2,2,2-trifluoro-1-(trifluoromethyl)ethylidene]diphenol and its salts to the REACH Candidate List of substances of very high concern. ECHA describes uses that can include coatings, cleaning agents, polymer processing and other industrial applications. This does not mean a particular metal buckle or coating contains either substance.
Why hardware buyers should review the update
Finished hardware may involve base metal, plating, coating, polymer inserts, adhesives or cleaning processes. Those inputs can involve different chemical obligations. The correct response is a targeted materials review rather than a blanket claim that all products have failed or passed REACH.
Supplier questions worth asking
- Which materials and purchased chemicals are used for the exact part and finish?
- Can the supplier identify the substance names and current safety data sheets for relevant mixtures?
- For an article supplied into the EU, has the supplier checked Candidate List content and any applicable information or notification duties?
- Is there a documented process to review changes when a new finish or sub-supplier is approved?
ECHA states that Candidate List inclusion can create immediate legal obligations, including communication duties for articles containing an SVHC above applicable thresholds. The applicable obligation depends on the product and role in the supply chain. A safety data sheet for a coating mixture is not automatically a declaration about the finished article.
Buyer takeaway
Request a current, part-specific materials declaration and test evidence where risk assessment calls for it. Record the revision and date. Do not treat “REACH compliant” as a substitute for identifying the substance, the article and the legal requirement being assessed.
