New Spanish biocides decree: what changes for manufacturers, sellers and applicators

Royal Decree 952/2026, published on 6 November 2026, brings together the Spanish rules on registering, manufacturing, storing, selling and using biocides, complementing EU Regulation 528/2012. It applies generally from 1 July 2027.

Premises that make, pack, store or sell biocides and treatment services must be registered with their regional authority (ROESB). Professional applicators will need certified training for most product types; the legionella maintenance certificate covers product types 2, 4, 5 and 11, and current staff have six years to comply. Labels must be at least in Spanish, and claims such as “sanitising” are now treated as biocidal claims.
