India’s Finance Ministry has granted full customs duty exemption on 40 critical petrochemical products effective from April 2 to June 30, 2026, in a direct policy response to the supply disruptions and input cost inflation triggered by the West Asia conflict and the Hormuz closure. The gazette notification, issued on April 1, covers a comprehensive range of feedstocks, intermediates, monomers, and polymers that collectively serve as the raw material backbone for much of India’s manufacturing sector.
The products covered span the full petrochemical value chain: basic feedstocks including anhydrous ammonia, methanol, acetic acid, toluene, and styrene; intermediates such as vinyl chloride monomer, monoethylene glycol, phenol, and purified terephthalic acid; and polymers including polyethylene, polypropylene, polystyrene, polyvinyl chloride, polycarbonates, PET chips, epoxy resins, and polyurethanes. The breadth of the list reflects a systemic concern: petrochemical input costs have been rising across the manufacturing economy since the Hormuz blockade began on February 28, and the government has moved decisively to prevent those cost increases from cascading into retail prices for end consumers.
Who Benefits: Plastics, Pharma, Textiles, Automotive
The Finance Ministry’s statement identifies the primary beneficiary sectors as plastics and packaging, textiles, pharmaceuticals, chemicals, and automotive components. India’s pharmaceutical industry — which is the world’s largest generic drug producer and has already been flagged as facing up to USD 750 million in export losses from Gulf market disruptions — depends heavily on petrochemical intermediates for both drug synthesis and packaging materials. A zero-duty environment for these inputs provides a meaningful cost buffer at a time when the sector is already absorbing elevated air freight costs for export shipments.
For the auto components sector, whose export performance has been one of the bright spots of India’s FY26 trade story, the duty waiver on polypropylene, polycarbonates, and polyurethanes — materials used extensively in interior components, bumpers, dashboards, and seating — reduces input cost pressure and supports the production economics of manufacturers targeting both domestic and international markets.
Domestic Production Constrained by LPG Diversion
The duty waiver is particularly important because domestic petrochemical production has itself been constrained since the crisis began. The government diverted butane and propane supplies — feedstocks normally used in petrochemical plants — toward cooking gas production to maintain household LPG availability, and restricted natural gas supplies to refineries and chemical plants. This created a domestic supply shortfall precisely when import disruptions were already tightening the market. The zero-duty window on imports directly compensates for the loss of domestic supply, ensuring that the manufacturing sector has access to petrochemical inputs from alternative global sources — including the US, Southeast Asia, and Europe — at lower landed costs.
The government has estimated the three-month exemption will result in an approximate revenue loss of ₹1,800 crore — a cost it has judged worth paying to contain industrial inflation and prevent downstream disruptions to supply chains that employ millions of workers. The time-bound nature of the measure to June 30 aligns with the government’s stated expectation that the West Asia situation will evolve within that timeframe, though the breadth of coverage signals that policymakers are preparing for a potentially extended disruption.
