PSE Certification Overview

In April 2001, Japan's "Electrical Safety Law" (referred to as the "EL Safety Law") came into effect, replacing the "Electrical Appliances Control Law" as the legal basis for market access of electrical products in Japan. Concurrently, the PSE mark replaced the original T mark. According to the EL Safety Law and technical standards issued by the Ministry of Economy, Trade, and Industry (METI), certified electrical products are categorized into Specific Electrical Products (SPs) and Non-Specific Products (NSPs).

Diamond PSE Certification

For SPs, products must undergo testing and certification by authorized third-party certification bodies under the "Electrical Appliance and Material Safety Law," and factory inspections are required before they can be marked with the diamond-shaped PSE label (as shown in Figure 1), including items like wires and cables, fuses, wiring devices, single-phase small-power transformers, and heating appliances. For NSPs, no third-party certification is needed; manufacturers can simply make a compliance declaration and affix the circular PSE label (as shown in Figure 2) to enter the Japanese market, such as IT products, electronic entertainment, and home appliances (washing machines, refrigerators, etc.). In short, products categorized as SPs are subject to mandatory certification, while NSPs are voluntary certification products. As of January 2010, there were 115 types of SP products and 338 types of NSP products.

PSE Certification for Lithium-ion Batteries

PSE certification is a mandatory requirement for entering the Japanese market. Batteries and any other products without PSE certification are not permitted for sale in Japan. Lithium-ion batteries within a specific range exported to Japan must comply with the legal requirements for supplier declarations and must display the relevant PSE label upon launch. Batteries are categorized as non-restricted products, belonging to Category B. This certification utilizes the JIS C 8712 standard for safety requirements of sealed secondary cells or batteries for portable devices and JIS C 8714 for safety testing standards of small lithium-ion batteries and battery packs for portable devices. Our company offers PSE certification services in circular format to help your products smoothly enter the Japanese market.

Battery PSE Certification Scope

As of November 20, 2008, lithium-ion batteries with energy densities exceeding 400 Wh/L, used in mobile devices, desktop notebooks, etc., have been included in the controlled scope of NSPs. The following lithium-ion batteries are excluded:

Lithium-ion batteries for medical equipment, industrial machinery, and automotive applications.

 Batteries that are securely fastened to the product using welding or other methods, not easily removable.

Battery with Special Structure.

The company boasts a full set of PSE battery testing equipment.

How Manufacturers Can Obtain PSE Certification

As more countries join the WTO, to align with international standards, many nations have established regulations that limit the safety, energy efficiency, and environmental protection technical specifications of various products. This not only ensures their domestic industry and market levels but also creates a certain level of technological barrier. It is well-known that Japan has a complex safety regulatory system. Foreign products seeking entry into the Japanese market will face higher entry barriers.

Manufacturers seeking PSE certification must first confirm that their product is within the scope of certifications authorized for handling by the Quality Certification Center (CQC). As the current authorization for CQC is based on Technical Standard 2, manufacturers must apply for PSE certification under this standard. Upon confirmation, they can submit a written application to the CQC and provide samples along with technical documents to the PSE certification laboratory for type testing. Since both China and Japan are members of the IECEE-CB system, the test report can also be directly converted from a CB report. After completing the test report, applicants must provide the Japanese user or assembly manual, product-related structural and component information, test equipment details, and factory quality inspection reports (including electrical intensity test reports on production lines and operational check records), and undergo a factory inspection arranged by the CQC. Upon passing the factory inspection, the PSE certification certificate can be obtained.

PSE Certification Documentation Preparation

1. Application Submission: Business License, Application Form

2. Test Preparation Materials:

1) CB Report (including Japan's differential testing)

2) Roadmap (Layout)

3) PCB design schematics related to safety regulations;

4) Specifications for transformers and coil components

5) List of key components and their certificates

6) Japanese user manual or assembly manual

7) Japanese label and warning signs (including PSE mark and supplier's name notification);

8) Structural Data Tables

9) A list of factory production materials and calibration certificates.

3. Sample Testing Provided: At least two units of the main inspection model, one unit of each derivative model.

Japan PSE Certification Requirements

Special Note: Although Japan is a member of the CB, the CB reports are generally to be used as a reference only. In cases where the CB conducts deviation tests for Japan, a direct certification by CB is applicable, with the certification cycle approximately around 3 weeks.
