Difference between the circular and diamond-shaped PSE marks: A detailed explanation of Japan's Electrical Appliance and Material Safety Law and application fees

The circular PSE mark applies to all "non-specific electrical appliances" listed in Appendix 9 of the law, excluding the "specific electrical appliances." These products are numerous and relatively low-risk; therefore, the regulatory model relies primarily on self-verification by the companies. Manufacturers or importers must test their products according to Japanese technical standards (usually harmonized with JIS, JET, or IEC standards) and affix the circular PSE mark themselves after confirming product compliance. The mark consists of the letters "PSE" within a circular border, often accompanied by information about the declarant of conformity (such as the manufacturer). The entire process does not require mandatory third-party certification, but relevant test records and declarations of conformity must be properly preserved for verification. This model grants companies significant autonomy while emphasizing their primary responsibility.

The diamond-shaped PSE mark, on the other hand, is specifically for the 116 types of "specific electrical appliances" explicitly defined in Appendix 9 of the Electrical Appliance and Material Safety Law. These products typically pose higher safety risks, such as wires and cables, fuses, wiring equipment, transformers, electric heating appliances, and power tools. The control over such products is extremely strict. Type testing and factory inspections must be conducted by third-party certification bodies authorized by the Japanese Ministry of Economy, Trade and Industry (METI) (such as JET and JQA) to ensure continuous compliance with standards. Only after passing the evaluation and obtaining a certification certificate can the diamond-shaped PSE mark be affixed to the product. The design consists of the letters PSE within a diamond border. This process ensures that high-risk products undergo independent and authoritative verification, providing stronger protection for market safety.

In summary, the core differences are: the circular PSE mark corresponds to "non-specific electrical appliances" and uses a self-certification model; the diamond-shaped PSE mark corresponds to "specific electrical appliances" and uses a mandatory third-party certification model. Legal basis, applicable product catalogs, and conformity assessment procedures are the core dimensions distinguishing the two.

Regarding application fees, there is a significant difference. For the circular PSE mark, the main cost lies in the product testing stage. Companies can conduct tests themselves or entrust third-party laboratories to do so according to standards. The cost varies depending on the product complexity and the number of test items, typically ranging from several thousand to tens of thousands of RMB. If a company already has its own qualified laboratory, the cost can be absorbed internally. The cost of the diamond-shaped PSE mark is much more complex, mainly including: 1. Certification application fee; 2. Product type testing fee (this is the main part, depending on the complexity of the product); 3. Factory inspection fee (initial and subsequent annual surveillance inspections); 4. Certificate annuity, etc. The total cost is usually much higher than the round mark, potentially ranging from tens of thousands to hundreds of thousands of RMB, and annual maintenance fees are also required. The specific amount depends on factors such as the product model and the certification body's quote.

Whether applying for round or diamond-shaped PSE certification, companies need to prepare sufficient technical documentation, including but not limited to product manuals, circuit diagrams, parts lists, specifications, and test reports. It is recommended that companies consider the regulatory requirements of the Japanese market in the early stages of product design and choose appropriate standards for pre-testing to avoid time and cost losses due to later rectification. For diamond-shaped mark products, communicating with experienced certification consulting agencies or directly with accredited certification bodies in advance can more effectively plan the process and budget.

Successfully obtaining PSE certification and affixing the correct label is not only a legal requirement but also strong proof of product quality and safety. It significantly enhances the confidence of Japanese consumers and buyers, giving companies a competitive edge in the fiercely competitive Japanese market. It is essential to accurately classify your products and follow the corresponding compliance pathways.
