China’s Ministry of Commerce has launched an expiry review of anti-dumping measures on imported solar-grade polycrystalline silicon originating in the United States and South Korea.
The review was requested by China’s domestic polysilicon producers and will consider whether ending the decade-old tariff regime would lead to renewed dumping and harm China’s domestic producers.
