The Directorate General of Trade Remedies has initiated a countervailing duty probe into Chinese insoluble sulphur imports following a complaint by Oriental Carbon and Chemicals Ltd (OCCL). This investigation aims to address alleged unfair subsidies, adding to recent regulatory measures taken to protect domestic pricing. The outcome could significantly impact the tyre industry, which is the primary consumer of this chemical.
The Directorate General of Trade Remedies (DGTR) has formally started a countervailing duty (CVD) investigation into imports of insoluble sulphur originating from China. Registered as Case No. CVD/OI/008/2026, the inquiry follows a petition filed by Oriental Carbon and Chemicals Limited (OCCL), which is the country’s only producer of this specialized chemical.
OCCL has alleged that Chinese manufacturers are benefiting from 79 distinct state-backed subsidy programs. These subsidies reportedly include preferential land allocation, low-cost electricity, and various tax concessions, which the company claims have allowed Chinese exporters to suppress prices artificially. By investigating these alleged state advantages, the DGTR aims to determine whether such support has caused material injury to the domestic manufacturing sector.
Regulatory History and Recent Actions
This probe is the latest in a series of trade protection measures targeting Chinese imports. In September 2026, the government acted on an anti-absorption investigation, recommending an increase in anti-dumping duties on Chinese insoluble sulphur from $307 per tonne to $485 per tonne. This retrospective hike, effective from July 2026, was designed to counter the practice of Chinese firms slashing export prices to bypass earlier duty structures.
Investors should note that these regulatory steps are closely tied to the competitive landscape of the tyre industry. Since the rubber sector consumes over 90% of the domestic supply of insoluble sulphur, any major change in import duties or pricing directly affects the cost structures of major tyre manufacturers.
Business Context and Risks
OCCL, as the dominant domestic player with an estimated 55% to 60% market share, has maintained a relatively stable financial position, characterized by low long-term debt levels of approximately ₹19 crore as of the last fiscal year. Despite this stability, the company operates in a cyclical market. Its profitability remains sensitive to global sulphur price fluctuations, which are difficult to hedge against.
Furthermore, while these investigations are intended to curb unfair competition, the company faces inherent risks from ongoing trade tensions. Retaliatory pricing from international competitors or shifts in global trade policies could influence future demand. Additionally, the final impact of these trade remedies depends on the government's official notification and the actual implementation of these duties at the ports.
The investigation is currently underway under the World Trade Organization’s framework. The DGTR has set a timeline for stakeholders, including domestic importers and Chinese producers, to submit their responses. The next critical update for investors will be the DGTR’s preliminary findings, which will provide clarity on whether temporary duties might be imposed while the final inquiry continues.
