The Chinese government is considering export restrictions on solar wafers, black silicon and silicon foundry equipment. It has launched a public consultation process on the proposed measures.

China's Ministry of Commerce (MOFCOM) and Ministry of Science and Technology (MOST) announced that they plan to revise the national catalog of export-prohibited and restricted technologies.

The two ministries said in a joint statement that three technologies related to the photovoltaic manufacturing industry could be included in the catalog - silicon wafers, black silicon and ingots. If these three types of products are added to the restricted list, manufacturers need to obtain technology export licenses from relevant provincial departments to export such products.

According to a report by the China Photovoltaic Industry Association (CPIA), China will account for more than 98% of the solar industry's silicon wafer production in 2021. Although the plan is still in the public consultation phase, the attempt demonstrates China's efforts to protect its most advanced solar technology and keep its solar industry competitive.
