TYN(SZ:000591) Shang Wu Bu Wang Zhan·2026-01-13 08:41Core Viewpoint - The Ministry of Commerce of China has decided to continue imposing anti-dumping duties on solar-grade polysilicon imported from the United States and South Korea, effective from January 14, 2026, for a period of five years [2][3]. Group 1: Anti-Dumping Measures - The anti-dumping duties for U.S. companies range from 53.3% to 57%, while for South Korean companies, the rates range from 2.4% to 113.8% [7][8]. - The Ministry of Commerce conducted an investigation and determined that if the anti-dumping measures are terminated, the dumping of solar-grade polysilicon from the U.S. and South Korea may continue or recur, potentially harming China's solar-grade polysilicon industry [2][3]. Group 2: Product Description - The investigated product is solar-grade polysilicon, produced using methods such as the Siemens process and silane process, primarily used for manufacturing crystalline silicon photovoltaic cells [5][6]. - The electrical parameters of the product include a base phosphorus resistivity of <300 ohm·cm and a base boron resistivity of <2600 ohm·cm [5]. Group 3: Implementation Details - The anti-dumping duties will be calculated based on the customs-determined taxable price of the imported goods, with the formula: anti-dumping tax amount = customs-determined taxable price × anti-dumping tax rate [8]. - The announcement regarding the continuation of these measures will take effect on January 14, 2026 [10].
