CMJ Registration Benefits
CMJ Registration is a voluntary approval system for components and materials used in electrical products and is intended to supplement the PSE Law and S-mark schemes.
CMJ Registration is accepted in place of individual component testing by all certification bodies that issue PSE certification and S-mark certification.
For component and material manufacturers, CMJ Registration can provide a competitive edge for obtaining supplier contracts with end product manufacturers in Japan. Further, obtaining CMJ Registration prior to providing components and materials is a useful tool to confirm whether your components are in compliance with Japanese requirements.
For end product manufacturers, using CMJ-registered components in products can greatly reduce end product certification costs and lead times.
If you intend to sell your product in Japan, it is highly recommended that you select component suppliers that have obtained CMJ Registration.

Components and materials can be registered under the following 15 categories.
