What is PSE Japan Certification?

PSE (Product Safety of Electrical Appliance & Material)certification in Japan is officially referRED to as a "Conformity Inspection." It is a mandatory certification system for electrical products entering the Japanese market. The certification uses a unified pse markand enforces stricter penalties on importers.

Electrical products in the Japanese market are regULated under the Electrical Appliance and Material Safety Act, established by the Japanese government and the Ministry of Economy, Trade and Industry (METI). Products are classified into:

1.        Specified Electrical Appliances (Category A)

2.        Non-specified Electrical Appliances (Category B)

Products under Category Amust pass third-party certification by a METI-authorized certification body, obtain a conformity certificate, and display a diamond-shaped PSE markon the label before entering the Japanese market.

For Category B, which falls under the round PSE markrequirements, manufacturers may conduct their own testing and inspections. After self-declaration of conformity, the products can legally enter and be sold in the Japanese market.

Regulations

1. Specified Electrical Appliances (Category A)

Requirements:

emc testing + Safety testing + Factory inspection = Diamond-shaped PSE mark

Process:

Before entering the Japanese market, manufacturers must obtain a conformity certificate from a METI-authorized third-party certification body.

Only after obtaining this certificate can they label the product with the diamond-shaped PSE mark.

### 2. Non-specified Electrical Appliances (Category B)

Requirements:

EMC testing + Safety testing = Round PSE mark

Process:

As long as the product meets the relevant requirements of the Electrical Appliance and Material Safety Act, manufacturers may apply the round PSE mark by themselves.
