Japan PSE Certification

Adding value with our service portfolio

In Japan, the Ministry of Economy, Trade and Industry (METI) is the regulatory agency responsible for the Electrical Appliance and Material Safety Law which regulates the manufacture and sale of electrical and electronic products to prevent potential hazards. Electrical and electronic products regulated by the Law are classified as Specified Electrical Appliances and Materials (Category A) and Non-Specified Electrical Appliances and Materials (Category B).

Importers of electrical appliances and materials (hereinafter refers to “electrical appliances“, be it Category A or Category B have the obligation to ensure that the appliances conform to the mandatory technical requirements, and to affix the applicable PSE mark on the appliance before placing the appliance on the market.

Particularly, any Specified Electrical Appliance or Material (Category A) shall undergo third-party conformity assessment and be marked with the PSE diamond mark after successful certification by the third-party conformity assessment body. TÜV SÜD, authorised by METI to perform certification for Specified Electrical Appliances (Category A) is the gateway for manufacturers exporting electrical appliances to the Japan Market. Our extensive experience in the Japanese market allows us to deliver the complete suite of services covering testing, factory inspections and certification.

What is PSE Mark Certification Scheme?

Manufacturers of Specified Electrical Appliances and Materials (Category A) and Non-Specified Electrical Appliances and Materials (Category B) may have their products certified by TUV SUD under the PSE Mark Certification Scheme.

Safety and EMC characteristics of products are evaluated to ascertain compliance to technical requirements under the Scheme. An evaluation of a manufacturer’s factory facility is also performed if the product is a Category A electrical appliance.

A Category A electrical appliance can only be affixed with the TÜV SÜD’s PSE Diamond Mark after successful certification. The manufacturer is expected to ensure that its factory can manufacture the certified electrical appliance to continuously conform to the mandatory technical requirements after initial certification and for the full period where the electrical appliance is certified under the PSE Mark Certification Scheme.


Type approval is granted to a Category B electrical equipment that complies with the technical requirements. The PSE Mark Certification Scheme is a useful means for manufacturers of Category B electrical appliances to support their attestation of conformity to the Electrical Appliance and Material Safety Law by having their product type approved.
