China has announced anti-dumping measures targeting specific optical fiber products imported from the United States, marking its first anti-circumvention investigation in this sector. The measures take effect September 4, 2024, following a six-month probe initiated at the request of a domestic company.
The Ministry of Commerce stated that U.S. exporters circumvented existing trade restrictions by modifying product specifications of dispersion unshifted single-mode optical fiber. Investigators found cut-off shifted single-mode optical fiber shipments effectively bypassed China's anti-dumping duties originally imposed in 2021.
"The investigation adhered to legal standards and ensured transparency for all stakeholders," a ministry spokesperson said, emphasizing China's commitment to fair trade practices. The ruling extends existing anti-dumping tariffs to cover the modified fiber products, though specific duty rates remain unchanged.
This decision comes amid growing global demand for optical fiber infrastructure, particularly in 5G networks and data centers. Analysts suggest the move could reshape supply chain strategies for telecom equipment manufacturers while reinforcing China's efforts to protect its domestic photonics industry.
