The Ministry of Industry and Information Technology (MIIT) has recently released the Interim Provisions on Radio Management of Wireless Charging (Power Transmission) Equipment (the “Provisions) dated May 22, 2023.

This regulation applies to the following equipment:

1. Mobile and portable wireless charging devices operated in frequency bands: 100-148.5kHz、6765-6795kHz、13553-13567kHz / Rated transmission power: not exceeding 80W.

2. Wireless charging equipment for electric vehicles (including motorcycles) operated in frequency bands: 19 -21kHz/ Rated transmission power: 22kW~ 120kW; frequency: 79 -90kHz/ Rated transmission power: not exceed 22kW.

For the production or importation of the above wireless charging equipment that is sold and used in China, SRRC approval is not necessary, but the equipment must comply with the technical requirements in current Provisions and other relevant laws and regulations.

According to the Provisions, showing certain product information in the operational instructions, including electronic instructions is mandatory.

The wireless charging equipment should be affixed with a specific mark (or shown on an electronic display).

If it’s impossible to show this mark in the above-described ways, it can be shown in the individual package or in the equipment’s operating instructions.

The regulation for the marking will be published later.

The Provisions will be enforced on September 1, 2024. Wireless equipment produced or imported before this date can still be used until it is scrapped.
