Act on Product Safety of Electrical Appliances and Materials

PSE stands for Product Safety Electrical Appliance & Material.

The PSE symbol can be found on appliances that are approved for use in Japan.

DENAN is a mandatory national law administered by Japan's Ministry of Economy, Trade and Industry (METI), which was formerly called the Electrical Appliance and Material Control Law (“DENTORI”).

These specified electrical appliances are either required to undergo third-party conformity assessment, and obtain their certificate, or obtain “the equivalent of a certificate” through the manufacturers of the specified electrical appliances concerned.

The Notifying Supplier (importer) is responsible for ensuring that the product is tested in accordance with the requirements by a RCAB (or “Registered Conformity Assessment Body”).
