The Directorate General of Trade Remedies (DGTR), under the ministry of commerce & industry, Government of India, has recommended imposition of anti-dumping duty (ADD) on sodium hydrosulphite (SHS), whether produced using Zinc or Sodium Formate process. The duty would be applicable on SHS originating in or exported from China and South Korea.

SHS is also known as Hydrosulphite Concentrate or Sodium Dithionite or Sodium Hydrosulfite (Na₂S₂O₄). It is a white or grayish white powder, free from visible foreign particles with pungent odour. It is classifiable under the custom codes 28311010 and 28321020.

The products using the Zinc process and Sodium Formate process can be used interchangeably in a number of applications. While the users in the denim (textile) industry prefer the product produced using zinc route due to properties such as low dusting, better stability, etc, but such consumer are limited and the majority of consumers use the products interchangeably, the domestic industry said in its submission to the DGTR, according to an official notification.

In the textile industry, Sodium Hydrosulphite is used for dyeing of Vat and Indigo dyes and reduction clearing of synthetic fabric for stripping of dyes.

DGTR had initiated the anti-dumping investigation a year ago, and has now recommended imposition of ADD equal to the lesser of margin of dumping and the margin of injury, so as to remove the injury to the domestic industry.

The Authority has recommended imposition of ADD $440 per metric tonne (MT) on SHS originating in or exported from China. It has also recommended imposition of $300 per MT on SHS originating in or exported from South Korea.

The ADD will remain in force for a period of five years from the date of notification to be issued in this regard by the Indian government, the DGTR said.
