In a move to support the domestic optical fibre industry, the Finance Ministry has implemented a definitive anti-dumping duty on specific optical fibre imports from China, South Korea, and Indonesia. This decision comes as a response to the negative impact caused by low-priced and low-quality imports on the industry. The imposition of this anti-dumping duty, based on recommendations from the Directorate General of Trade Remedies (DGTR), applies to dispersion unshifted Single-Mode Optical Fiber (SMOF) imports from the aforementioned countries. The duty ranges from$122 to$857.23 per kfkm (fibre kilometres), with the duration set for five years.

Birla Furukawa Fiber Optics Pvt Ltd filed a petition for an anti-dumping probe on SMOF imports from China, South Korea, and Indonesia. Sterlite India Technologies and Corning India Technologies supported the petition. These three producers make up 90% of India's SMOF production. The revenue department's decision to impose anti-dumping duty on optical fiber comes at a time when India is focusing on digitization and expanding network services.
