India Opens Dumping Probe on Chinese, Japanese Tyre Chemical

India's commerce ministry has started an anti-dumping investigation into imports of a chemical used in tyre and rubber manufacturing from China and Japan, according to a notification from the Directorate General of Trade Remedies.

The probe covers a rubber-processing chemical – p-phenylenediamine – that acts as an antioxidant and antiozonant in tyre compounds, conveyor belts, and industrial rubber goods. Domestic producers told the DGTR that imports from the two countries are undercutting local prices by a wide margin, threatening the viability of the Indian industry.

Anti-dumping duties, if imposed, would raise the landed cost of the Chinese and Japanese material, potentially pushing tyre makers to source from alternative suppliers or raise product prices. The Indian tyre industry imports roughly 30-40% of its p-phenylenediamine needs, with China accounting for a large share, trade data show.

The investigation covers shipments into India from January 2024 to December 2024. The DGTR will send questionnaires to known exporters in China and Japan, domestic producers, and importers. A preliminary finding is expected within 90 days, followed by hearings and a final ruling.

India has stepped up anti-dumping investigations in the chemicals sector over the past two years, particularly against Chinese imports. Domestic chemical makers have complained about excess capacity in China spilling into global markets and depressing prices. The move comes as India pushes for greater self-reliance in intermediate chemical production through production-linked incentive schemes.

For tyre makers such as Apollo Tyres, MRF, and CEAT, the probe introduces procurement cost uncertainty. If duties are levied, the added cost could squeeze margins in a sector already facing elevated natural rubber prices. Some tyre companies may accelerate plans to blend in alternative antioxidants or raise prices on replacement tyres, though the impact depends on the eventual duty rate.

The probe also follows a broader trend of India imposing trade barriers on Chinese goods in sectors where domestic capacity exists or is being built. In the past year, India has initiated anti-dumping probes into steel, aluminium, chemicals, and solar glass. The World Trade Organization allows such measures when a domestic industry can show injury from dumped imports.

commodities analysis traders and procurement desks will watch the DGTR's preliminary findings for early signals on duty levels. If the agency sets a preliminary duty before the final ruling, the chemical's landed cost could shift within weeks, altering input budgets for tyre and rubber fabricators.

The domestic producers who filed the petition – Nocil Ltd and a unit of the Aditya Birla Group – contend that the price gap is wide enough to justify a duty of 15-20% based on normal value calculations. Their petition cites declining capacity utilisation and falling domestic sales during the investigation period.

Japanese and Chinese exporters have 40 days to respond to the DGTR's questionnaire. The outcome will affect not just the two countries but also alternative suppliers in South Korea and Taiwan, who may adjust pricing to capture any market share that duties free up.

Shares of Nocil rose 3.2% on the day of the notification as the market interpreted the probe as a potential tailwind for the domestic producer. The broader specialty chemicals index was flat on the day.

The investigation will be one to track for anyone following India's chemical industry dynamics and its willingness to use trade remedies against key suppliers.
