Japan PSE Certification

 Japan PSE Certification



Certification Introduction


PSE certification (Product Safety of Electrical Appliance & Materials) is a market access system implemented by the Japanese government for electronic and electrical products. It is an important part of Japan's Electrical Product Safety Law (DENAN). On April 1, 2001, Japan revised the DENAN law, placing it under the management of METI (Ministry of Economy, Trade and Industry). METI does not directly issue certificates but authorizes third-party certification bodies to conduct conformity assessment tests and issue certificates.


METI authorizes the Japan Electrical Safety and Environmental Technology Research Laboratory (JET) and the Japan Quality Assessment Agency (JQA) as Qualified Certification Bodies (CABs) to conduct testing and certification of electronic and electrical products and to supervise the market, in accordance with regulations. In addition, TUV, UL, CQC, and other organizations are also Qualified Certification Bodies.


According to regulations, all controlled electronic and electrical products must submit a business declaration to the Minister of Economy, Trade and Industry before being manufactured or exported to Japan, and the PSE mark must be affixed to the product as required by regulations. The Electrical Safety Law stipulates that Class A and Class B products must bear the PSE diamond mark and PSE circular mark, respectively. Two standards apply:


Ministry Ordinance 1: Japanese domestic standard (including EMI standard)


Ministry Ordinance 2: J standard (excluding EMI standard) = IEC standard + Japanese differences


Product Scope


To date, a total of 457 products fall under the scope of the Electrical Products Safety Law. Of these, 116 products, which are considered highly dangerous and prone to electric shock, fire, etc., are classified as "Specified Electrical Products – Class A Electrical Products," such as chargers and adapters. The remaining 341 products, which pose less of a hazard, are classified as "Non-Specified Electrical Products – Class B Electrical Products," including most large and small household appliances, lighting products, and lithium batteries.

Power Bank Safety Upgrade: First Mandatory National Standard Issued

图片
 Power Bank Safety Upgrade: First Mandatory National Standard Issued my country's first mandatory national standard, the "Technical Specification for Safety of Power Banks," was published on March 31, 2026, and will officially take effect on April 1, 2027. This standard aims to end long-standing problems in the power bank industry, such as falsely advertised capacity, substandard battery cells, and frequent safety incidents. The new regulation introduces several stringent technical requirements, mandating that battery cells pass a needle penetration test (without catching fire or exploding), and strengthening thermal abuse testing; it also adds tests for whole-device drop and crushing, requires products to be labeled with a safe service life, and improves various protection mechanisms.

EN IEC 62680-1-3/62680-1-2 EU Electronics Standards

图片
To reduce e-waste, the EU is committed to promoting a unified charging technology and interface that supports a variety of electronic products. On November 23, 2022, the EU issued Directive EN IEC 62680-1-3/62680-1-2, requiring electronic product manufacturers to use USB-C charging interface technology in their products. It also requires small and medium-sized portable electronic devices such as mobile phones, tablets, and cameras, as well as laptops, to comply with the USB-C charging interface requirement by 2024 and 2026, respectively. The IEC 62680 testing equipment GRL-USB-PD-C2-EPR, formerly the USB-IF Association's USB PD certification testing instrument, performs PD protocol certification testing. IEC 62680-1-2 and IEC 62680-1-3 incorporate the USB-IF USB PD and Type-C specifications and are currently used for protocol testing and certification corresponding to IEC 62680. IEC 62680-1-2 primarily defines the USB PD power supply specification; IEC 62680-1-3 is a specification ...

 What is FDA Certification & What is FDA Registration? I. What is the FDA? The FDA, authorized by the U.S. Congress (the federal government), is the highest law enforcement agency specializing in food and drug regulation. Its full name is the Food and Drug Administration. Strictly speaking, there is no such thing as FDA certification; the FDA itself has stated this. Generally, when people talk about FDA certification, they are referring to the following three types: FDA registration, FDA testing, and FDA approval. ① FDA Registration: Companies exporting food, drugs, and medical devices to the United States must register with the FDA, listing their company and products. Otherwise, customs clearance will be denied; this is a mandatory requirement. ② FDA Testing: FDA testing primarily refers to safety testing of food contact materials, testing of product contact packaging, biocompatibility testing of medical products, and clinical safety testing. ③ FDA Approval: This usually appli...
