Radio Law Scope

The Radio Law covers all products which utilize the radio spectrum and operate under 3 THz.

In some cases, this includes products that are not radio communications devices, such as discharge lamps and induction heating devices. Simply applying the PSE mark to such products may be insufficient for entry into the Japanese market.

Regarding most consumer-use equipment within its scope, the Radio Law divides products into three categories.

Specified Radio Equipment High-Frequency Devices Extremely Low-Power Devices
