J-Moss (Japan RoHS)

J-Moss (Japanese Industrial Standard JIS C 0950:2008 — ‘Marking for the Presence of the Specific Chemical Substances for Electrical and Electronic Equipment’) is Japan’s RoHS-equivalent marking standard. It applies to seven categories of EEE and six restricted substances (the same six as EU RoHS 1: lead, mercury, cadmium, hexavalent chromium, PBBs, PBDEs). J-Moss requires a J-Moss mark to be displayed on products indicating whether restricted substances are present above a threshold. Unlike EU RoHS, J-Moss is a JIS standard (not a law), making it a market expectation rather than a legal mandate in most cases, though it aligns with the Law for the Promotion of Effective Utilization of Resources (LPEUR).

Japanese customers and retailers increasingly require J-Moss compliance for EEE. The J-Moss assessment methodology aligns closely with EU RoHS, making dual compliance relatively straightforward for EU-compliant products. The key difference is the labeling requirement: products with above-threshold restricted substances display a different mark than those below threshold. Manufacturers exporting to Japan should verify J-Moss marking requirements with Japanese importers or distributors.
