In response to the US-Iran conflict supply chain threat, India recently canceled custom duties on essential petrochemicals until June 2026. This action levels out local industries in the face of international shocks.
The rising US-Iran tensions have interfered with the petrochemical supply of West Asia, which is a threat to the manufacturing base of India.
To make sure that there is availability of the critical petrochemicals and to check their costs, the government declared on April 1, 2026 full customs duty exemptions on approximately 40 critical petrochemicals, effective April 2. The waiver is valid until June 30, 2026 with industrial continuity taking first priority.
What is the Reason Behind Custom Duty Waiver?
The US-Iran war has increased the ship security risks along major export routes of petrochemicals such as the Strait of Hormuz. India depends on the region to import more than 30 percent of its petrochemical requirements, which are in short supply and rising prices.
This caused a rapid response in policy to protect industries such as plastics and textiles against inflation.
What is the Government Announcement?
The exemption was issued by the Finance Ministry, through the Press Information Bureau on April 1, 2026. It focuses on downstream production feedstocks, polymers and specialty chemicals. Extensions will be evaluated before June end according to the stability of supplies.
Complete list of Exempted Petrochemicals
The waiver provides an approximate of 40 items in categories as provided in government aligned reports. Basic customs duty on imports is now zero.
| Category | Key Exempted Items |
| Basic Inputs | Anhydrous ammonia, Methanol, Toluene, Styrene, Vinyl chloride monomer, Monoethylene glycol (MEG), Phenol, Acetic acid, Purified terephthalic acid (PTA), Dichloromethane |
| Polymers | Polyethylene (all grades), Polypropylene, Polystyrene, Polyvinyl chloride (PVC), Polyethylene terephthalate (PET) chips, Poly butadiene rubber, Styrene butadiene rubber, Acrylonitrile-butadiene-styrene (ABS), Polycarbonates |
| Speciality Chemicals | Unsaturated polyester resins, Epoxy resins, Polyurethanes, Formaldehyde derivatives, Polyols, Alkyl phenols |
Impacted Sectors
The greatest benefactors are plastics processors, packaging companies, textile, pharmaceutical, automotive components and construction materials. The industries would save billions of dollars in lower input costs, which would stabilize the price of consumer goods.
Economic Implications
The waiver reduces importation costs by 7.5-10% duties, reducing inflation pressure on essentials such as packaging. It enhances competitiveness in manufacturing due to global volatility. In the long term, it promotes domestic capacity but exposes it to dependency on imports in case of a continued conflict.
The exemptions last between April 2 and June 30, 2026, and they are reviewed in relation to the geopolitical occurrences. CBIC will monitor the import data and supply flows to renew it. End-use verification should be conducted to avoid misuse in industries.
