Core Viewpoint - The Ministry of Commerce of China announced new anti-dumping measures on specific types of optical fibers imported from the United States, reflecting changes in the trade environment [1] Group 1: Policy Changes - Starting from September 4, 2025, anti-circumvention measures will be applied to imports of related cutoff wavelength single-mode optical fibers originating from the United States, using the existing anti-dumping tax rate for non-dispersion shifted single-mode optical fibers [1] - Following changes in the trade environment, the Ministry of Commerce recommended to the State Council Tariff Commission to stop the application of the current anti-dumping tax rate on imports of related cutoff wavelength single-mode optical fibers from the United States [1] - The State Council Tariff Commission accepted the Ministry's recommendation, deciding to cease the application of the anti-dumping tax rate on these imports starting November 10, 2025 [1]

Core Points - The Ministry of Commerce announced the implementation of anti-circumvention measures on imports of related cutoff wavelength single-mode fibers originating from the United States starting September 4, 2025 [1] - The current anti-dumping tax rate applicable to non-dispersion shifted single-mode fibers from the U.S. will also apply to the related cutoff wavelength single-mode fibers [1] - Due to changes in the trade environment, the Ministry of Commerce recommended the cessation of these anti-circumvention measures, which was accepted by the State Council Tariff Commission, effective November 10, 2025 [1] Summary by Sections - **Announcement Details** - The Ministry of Commerce issued Announcement No. 48 of 2025 on September 3, 2025 [1] - The measures will affect imports of specific single-mode fibers from the U.S. [1] - **Tax Rate Application** - The existing anti-dumping tax rate for non-dispersion shifted single-mode fibers will be applied to the related cutoff wavelength single-mode fibers [1] - **Cessation of Measures** - The Ministry of Commerce proposed to stop the anti-circumvention measures due to changes in the trade environment [1] - The cessation of these measures will take effect on November 10, 2025 [1]

Core Viewpoint - The Ministry of Commerce has decided to stop implementing anti-circumvention measures on single-mode optical fibers with specific cutoff wavelength originating from the United States, indicating a shift in trade policy that may impact the optical fiber industry and related sectors [1] Group 1 - The decision to halt the anti-circumvention measures suggests a potential easing of trade tensions between the countries involved, which could lead to increased imports of U.S. optical fiber products [1] - This policy change may benefit domestic companies that rely on U.S. optical fiber technology, potentially enhancing their competitive edge in the market [1] - The move could also signal a broader trend of regulatory adjustments in the optical fiber industry, reflecting changing market dynamics and international trade relations [1]

Core Viewpoint - China has implemented anti-circumvention measures on imported optical fiber products originating from the United States, effective from September 4, 2025, following an investigation initiated by domestic companies [1] Group 1: Investigation and Measures - The Ministry of Commerce of China announced the initiation of an anti-circumvention investigation into the import of specific single-mode optical fibers from the U.S. due to potential circumvention of existing anti-dumping measures [1] - This case marks the first anti-circumvention investigation conducted by China [1] - The investigation revealed that U.S. optical fiber manufacturers and exporters altered trade practices to export specific single-mode optical fibers to China, undermining the effectiveness of current anti-dumping measures [1] Group 2: Implementation and Transparency - The Ministry of Commerce stated that the investigation process was conducted in a transparent manner, ensuring the rights of all stakeholders were protected [1] - Based on the investigation results, anti-circumvention measures will be implemented starting September 4, 2025 [1]

Group 1 - The General Administration of Customs announced that the Ministry of Commerce has issued Announcement No. 48 of 2025, which will implement anti-circumvention measures on imports of certain single-mode optical fibers originating from the United States starting from September 4, 2025 [1] - The current anti-dumping tax rate applicable to non-dispersion shifted single-mode optical fibers from the United States will also apply to the relevant cutoff wavelength single-mode optical fibers [1] - Importers or their agents must declare the relevant cutoff wavelength single-mode optical fibers under the specified commodity code 90011000, with the specific code 90011000.01 for declaration purposes [1]

Trade Measures - China's Ministry of Commerce found US exporters circumvented anti-dumping measures on US non-dispersion-shifted single-mode optical fiber by exporting related cut-off wavelength shifted single-mode optical fiber to China [1] - Anti-circumvention measures will be implemented starting September 4, 2025 [1]
