All electrical and electronic products in the DENAN catalog sold in the Japanese market must pass PSE certification.
        Japan’s DENTORL Law (Electrical Device and Material Control Law) stipulates that 498 products must pass safety certification to enter the Japanese market. Among them, 112 types of A products should obtain diamond (compulsory) certification, and 340 types of B products should obtain round (voluntary) certification.
        The diamond-shaped PSE Mark: belongs to the products in the "Specified Electrical Products" catalog. The diamond-shaped PSE mark can be affixed only after the manufacturer has obtained the certificate of conformity. The first application is subject to factory inspection, and an updated list of calibrated test equipment is submitted annually. According to different products, the certificate is valid for 3-7 years.
        Round PSE Mark: Japanese round PSE mark certified products, which are products in the "non-specific electrical products" catalog, enter the Japanese market and need to prove the conformity of the product through self-inspection and declaration before it can be posted on the product PSE round logo.
       Optional S logo certification
       The optional S mark certification is suitable for all electrical products-even products outside of the DENAN law. The S mark is an accredited designated safety certification for the Japanese market. It is a voluntary product safety mark, mainly based on the IEC standard that harmonizes the Japanese differential test. Owning S-Mark products will increase the confidence of retailers and consumers in the products and achieve trial production competitiveness. The factory inspection is required for the first time, and it is necessary to go through the factory inspection once a year. Validity: Permanently valid.
