Japan RoHS, also known as J-MOSS, is a set of crucial environmental regulations introduced by the Japanese government to reduce the presence of hazardous substances in electrical and electronic equipment. Derived from the initials "J" representing Japan and an acronym of JIS C 0950 (The Marking for presence Of the Specific chemical Substances for electrical and electronic equipment), J-MOSS has evolved since its initial issuance in 2005, with revisions in 2008 and March 2021.

Understanding J-MOSS (JIS C 0950: 2021)

J-MOSS falls under the Japanese Industrial Standards Act, specifically JIS C 0950, which sets guidelines for marking the content of six specific chemical substances in seven designated electrical and electronic products. The substances regulated under J-MOSS include:

For compliance, the concentration of these substances must adhere to specific limits in the following product categories:

1. Personal computers
2. Unit-type air conditioners
3. Television sets
4. Refrigerators
5. Washing machines
6. Clothes dryers
7. Microwaves

Marking Requirement for J-MOSS

J-MOSS introduces the concept of "marking for presence" through two distinct symbols:

1. Content Mark (Orange Mark): When the concentration of a substance exceeds the reference value in electrical and electronic equipment, manufacturers are required to use the content mark. They must provide a description, in Japanese and according to JIS standards, on their website regarding the presence condition of the six substances. Additionally, the orange mark must be placed on the product, packaging, and catalogues.
2. J-Moss Green Mark: This mark comes into play when certain substances exceed the designated threshold but qualify for exemptions outlined in Annex B of JIS C 0950:2021. Manufacturers need to provide a description on their website about the presence condition of the six substances and include the corresponding URL in their catalogues. Depending on the circumstances, the J-Moss Green mark may or may not be placed on the products, packaging, and catalogues voluntarily.

Associations Behind J-MOSS Marking

The responsibility for implementing J-MOSS and releasing the J-Moss Green mark guidelines lies with three influential associations:

• JEITA (Japan Electronics and Information Technology Industries Association)
• JEMA (Japan Electrical Manufacturers Association)
• JRAIA (Japan Refrigeration and Air Conditioning Industry Association)

Scope of Japan RoHS (J-MOSS): Obligations for Manufacturers

Manufacturers of electronic equipment bear the responsibility of compliance with J-MOSS regulations. They are defined as entities that:

• Manufacture and distribute electronic equipment under their own brand
• Resell equipment produced by other suppliers under their own brand
• Are responsible for importing or exporting applicable equipment into a nation covered by the J-MOSS directive

To ensure compliance, manufacturers must adhere to strict guidelines on the use of hazardous materials and banned compounds. They are required to stay informed about updates or changes to Japan's ROHS laws and maintain proper documentation and records.

Conclusion

Japan RoHS (J-MOSS) stands as a vital step in Japan's commitment to environmental preservation and sustainable practices in the electronics industry. Manufacturers must embrace compliance with J-MOSS regulations, not only to gain market access but also to contribute to the protection of the environment and public welfare. By understanding and adhering to J-MOSS guidelines, businesses can pave the way for a greener and more sustainable future for Japan and the global electronics market.
