China will slash test charges for its mobile phone makers by 25 percent on average starting June 1, the country's top economic planner said Friday.

The move aims to regulate charging activities imposed on Chinese businesses and relieve their financial burdens, the National Development and Reform Commission (NDRC) said in a notice concerning regulating and lowering fees charged on mobile phone tests.

Those tests include approvals of mobile phone models, Internet access and China Compulsory Certification (3C certification), according to the notice.

Also, testing organizations failing to submit test reports in five days will have to cut test fees by half. Tests will be free of charge if they submit reports in more than five days or reexamine defective phones, said the notice.

The move is expected to save 150 million yuan (about 23.08 million U.S. dollars) for the country's mobile phone makers annually, said the NDRC.
