The Chinese Ministry of Commerce will impose anti-dumping measures on optical fiber preforms after ruling that Japanese and U.S. companies are engaged in dumping.
A probe, launched on March 19 in 2014, found the two countries' dumping activities were damaging the interests of Chinese optical fiber producers, and that there was a causal link between the dumping and the damage caused.
The ministry told domestic importers of fiber optics from the two countries to pay anti-dumping tariffs ranging from 8 percent to 41.7 percent to customs.
The ruling will affect products with Harmonization System Code (HS-Code) 70022010, but exclude those with a diameter smaller than 60 millimeters.
Optical fiber preform is a piece of glass used to make optical fiber.
