Steam Generator Certifications Explained: CE, cTUVus, ETL and PSE — and the Markets Each One Unlocks
For importers, certification determines legal market access, sales channels and customs clearance. Mains-powered heating equipment like steam generators is strictly regulated worldwide.
North America accepts cTUVus or ETL; EU & UK require CE plus RoHS. Japan mandates diamond PSE (round PSE is invalid for steam generators and sauna heaters). Other regions have independent certifications such as KC, EAC, SABER, RCM, INMETRO and NRCS, which cannot be substituted by CE or cTUVus.
When selecting suppliers, verify model-specific certificates, issuing labs, report numbers and certificate holders. Our steam and sauna products hold CE, cTUVus, Diamond PSE, RoHS and over fifty certifications. Always check relevant approvals before shipment.
