China's Ministry of Commerce announced Friday that starting from Jan. 14, 2025, it will launch an expiry review of anti-dumping measures aimed at solar-grade polysilicon originating in the United States and the Republic of Korea (ROK).
The expiry review, requested by the domestic solar-grade polysilicon industry, will determine if terminating anti-dumping measures will lead to continued dumping and harm, the ministry said in a statement.
The Customs Tariff Commission of the State Council will maintain the anti-dumping duties during the review, with scope and rates remaining unchanged, according to the ministry.
Solar-grade polysilicon is the main raw material for the production of crystalline silicon photovoltaic cells.
On Jan. 20, 2014, China imposed anti-dumping duties on the United States and ROK-originated solar-grade polysilicon, with rates ranging from 53.3 to 57 percent for U.S. companies, and 2.4 to 48.7 percent for ROK companies.
In November 2017, China adjusted the rate range of anti-dumping duties on ROK-originated solar-grade polysilicon to 4.4 to 113.8 percent. In January 2020, China extended the anti-dumping duties for another five years, according to the ministry.

The two-day 2025 Brain-Computer Interface (BCI) Conference concluded on Friday in Shanghai, where multiple globally leading "China solutions" took center stage.
Under the theme "Brain connects the world, wisdom gathers in Shanghai," the event gathered research teams from major universities, leading industry developers, and experts across the BCI sector to strengthen the connection between research, application, and policy.
As part of the event, the first BCI competition featured four categories—fatigue detection, emotion recognition, brain-controlled robotic cars, and brain-controlled robotic arms - with 40 out of nearly 100 teams from across China received prizes.
In the BCI Industry Innovation Exhibition Zone, more than a dozen frontier-tech companies presented cutting-edge technologies ranging from key components to comprehensive system-level solutions.
Exhibits spanned the entire technology chain, from underlying hardware to clinical applications, covering fields such as sleep intervention, mental illness treatment, and rehabilitation for degenerative diseases—highlighting the latest trends in BCI development.
"We completed the first domestic clinical trial this March, and next year we will launch large-scale clinical trials," said an exhibitor named Chen Yaoxu.
Shanghai has established China's first future industry cluster dedicated to BCI technologies. During the conference, several new innovation platforms—including a BCI service platform and a joint laboratory for digital neuromedicine - were inaugurated.
"We are guided by clinical needs and clinical scenarios. At the same time, we are opening high-quality EEG datasets for enterprises to support their algorithm research and guide them in developing concrete products that truly address real-world needs," said Wang Zhuoyao, BCI Project manager of Shanghai Municipal Science and Technology Commission.
