In December 2014, the finance ministry had imposed the anti-dumping duty of USD 135.83 per tonne on the import of "Sodium Nitrite" from China. This was to be in force till August 16 this year.
Amending the notification, the Department of Revenue said it "shall remain in force up to and inclusive of August 16, 2017".
Deepak Nitrite Ltd had filed an application for sunset review initiation of anti-dumping investigation on import of the chemical.
Countries initiate anti-dumping probes to determine if the domestic industry has been hurt by a surge in below-cost imports. As a counter-measure, they impose duties under the multi-lateral WTO regime.
Anti-dumping measures are taken to ensure fair trade and provide a level-playing field to the domestic industry. They are not a measure to restrict imports or cause an unjustified increase in cost of products.
