Antidumping Investigation of Dispersion Unshifted Single-mode Optical Fibre Originating in or Exported from China, Indonesia and South Korea
10 May 2022

On 6th May 2022, the Directorate General of Trade Remedies of India (DGTR) has initiated an anti-dumping investigation concerning imports of “Dispersion Unshifted Single-mode Optical Fibre (SMOF)" which facilitates transmission of a single spatial mode of light as a carrier and is used for signal transmissions within certain bands originating in or exported from China, Indonesia and South Korea which falls under the tariff code of 90011000 of the First Schedule to the Customs Tariff Act, 1975. However, this customs classification is indicative only and in no way binding on the scope of the present investigation.


The product scope covers Dispersion Unshifted Fibre (G.652) as well as bend insensitive single mode fibre (G.657) as defined by International Telecommunication Union (ITU-T), which is a global standardization body for telecommunication systems and vendors. Dispersion shifted fibre (G.653), cut-off shifted single mode optical fibre (G.654), and non zero dispersion shifted fibres (G.655 & G.656) are specifically excluded from the scope of Product


The product under consideration is used for manufacture of Optical Fibre Cables, including uni-tube and multi tube stranded cables, tight buffer cables, armoured and un-armoured cables, ADSS & fig-8 cables, ribbon cables, wet core and dry core cables and others. Single-mode Optical Fibre is mainly applied to high-data rate, long distance and access network transportation, therefore, is mainly used in long-haul, metro area network, CATV, optical access network (for example FTTH) and even over short distance networks as applicable. Major consumption is driven by 3G/4G/5G rollout by Telco’s, Connectivity of Gram Panchayat and Defence (NFS Project).


The producers/exporters have been provided 37 days from the date of receipt of the notice to file their questionnaire responses by e-mail (12 June 2022), moreover, other producers/exporters not initially known in this investigation can also register as interested parties within 40 days from the date of initiation (15 June 2022).
