Project Description


The PSE mark is a mandatory certification mark required for many electrical appliances and materials entering the Japanese market. Products requiring the PSE mark fall under two categories regulated by the Japanese Electrical Appliance and Material Safety Law (DENAN).

The Electrical Appliance and Material Safety Law (DENAN) was established by Japan’s Ministry of Economy, Trade and Industry (METI) to regulate the safety of electronic and electrical products (Categories A and B).

Products classified under Category A need to pass conformance testing with a Registered Conformity Assessment Body before the manufacturer or importer can affix the Diamond PSE Mark on the product.

The Circle PSE Mark applies to the products classified under Category B. The manufacturer and importer of these products can self-declare conformity by testing to DENAN’s technical requirements at the manufacturing stage and keeping a copy of the test report.
