India Cellular and Electronics Association (ICEA) on Sunday asked the government to increase anti-dumping duty on optical fibre to 25 percent, especially on cheap Chinese imports. ICEA sent a letter to Revenue Secretary and Commerce Secretary expressing concerns over the high anti-dumping duty of 30 percent levied by China on Indian optical fibre. Directorate General of Trade Remedies (DGTR) has also suggested a 10 percent anti-dumping duty on the same responding to the grievance of domestic manufacturers.
