BEIJING - China's Ministry of Commerce said Wednesday that on Aug 14, 2025, it will launch an expiry review of anti-dumping measures aimed at single-mode optical fibers originating in India.

The expiry review, requested by the domestic optical fibers industry, will determine if terminating the anti-dumping measures will lead to renewed dumping and harm, the ministry said in a statement.

The Customs Tariff Commission of the State Council will maintain the anti-dumping duties during the review -- with the scope and rates remaining unchanged, according to the ministry.

China started to impose anti-dumping duties on imported single-mode optical fibers from India in August 2014, featuring tariff rates ranging from 7.4 percent to 30.6 percent. Such duties were reviewed and extended for five years in 2020.
