India Recommends Five-Year Extension Of China Sodium Hydrosulphite Anti-Dumping Duty

India Sodium Hydrosulphite Anti-Dumping Duty Is Recommended

The India sodium hydrosulphite anti-dumping duty should continue for another five years at USD 440 per metric tonne, according to a final sunset-review recommendation from the Directorate General of Trade Remedies. The final finding in case AD (SSR)-06/2026 is dated 15 September 2026.

The DGTR finding does not itself extend the duty. This article does not establish a subsequent implementing notification. The Central Government, acting through the Ministry of Finance, must issue a notification before the proposed measure becomes operative. The existing duty under Notification No. 71/2021-Customs (ADD) is scheduled to expire on 16 December 2026 unless renewed.

The product scope covers sodium hydrosulphite produced through zinc or sodium formate processes, including hydrosulphite concentrate, sodium dithionite, sodium hydrosulfite and SHS. Its chemical formula is Na2S2O4. Imports are reported under tariff codes 2831 1010 and 2832 1020, but the written product description governs coverage.

Recommendation Is Restricted To China

The proposed USD 440 per metric tonne duty covers subject goods originating in China and exported from any country, as well as subject goods originating elsewhere but exported from China. The duty table is designed to address both direct shipments and relevant routed exports.

The applicant sought continuation only against China, and the review was restricted accordingly. This recommendation does not revoke the existing Korean measure.

The authority found that the domestic industry was not currently suffering material injury while the duty remained in place. It nevertheless concluded that dumped and injurious imports from China were likely to recur if the measure expired. The final finding states that 99% of Chinese exports to third countries were dumped, 98% were at injurious prices and 95% were below Indian prices.

Sodium hydrosulphite is used as a reducing and bleaching agent in textiles, pulp, paper, sugar, molasses, glue and kaolin, and in pharmaceuticals, polymers and oxygen-scavenging applications. Using its stated SION consumption and pricing assumptions, DGTR estimated that the recommended duty would add about 0.17% to cotton-fabric costs, 0.31% to denim and sugar, 1.11% to cefaclor, 0.13% to cotrimoxazole and similarly limited proportions for other sampled downstream products.

The recommended five-year period would begin from the Central Government’s implementing notification, not from the DGTR finding. The estimates describe modelled effects, not observed price increases.
