Govt. exempts Customs Duty for 40 petrochemical products

What Happened

  • The Central Government on April 2, 2026, issued a notification exempting customs duty on 40 petrochemical products to protect domestic supply chains disrupted by the ongoing West Asia crisis.
  • The disruption stems from the effective closure of the Strait of Hormuz since late February 2026, following US-Israel military strikes on Iran. The Strait carries approximately 20% of world oil trade and a significant share of petrochemical feedstocks sourced by Indian industries.
  • The zero-duty window runs from April 2 to June 30, 2026 — a three-month emergency measure to stabilise input costs across manufacturing sectors that rely on petrochemical feedstocks.
  • The 40 exempt products span the full value chain: basic feedstocks (ammonia, methanol, ethylene, propylene derivatives), intermediates (PTA, vinyl chloride, acetic acid, phenol), and finished polymers (polyethylene, polypropylene, PVC, PET, polycarbonate, ABS, SAN, polyurethanes).
  • The exemption is expected to reduce input costs for industries including plastics, packaging, textiles (synthetic fibres), pharmaceuticals (API synthesis), and automotive components.
  • The notification was issued under Section 25 of the Customs Act, 1962, which permits the Central Government to waive customs duties in the public interest without requiring parliamentary approval.

Petrochemical Value Chain: From Crude Oil to Consumer Products

Petrochemicals form a long value chain originating in crude oil and natural gas refining. At the top are primary feedstocks (ethylene, propylene, methanol, benzene, toluene, xylene), which are processed into intermediates (PTA, vinyl acetate, acetic acid, phenol) and then into final polymers (PE, PP, PVC, PET, PS, ABS) and downstream products. These polymers are the raw materials for plastics, synthetic textiles (polyester, nylon), packaging films, pharmaceutical bottles and blister packs, auto parts (bumpers, dashboards), and construction materials (PVC pipes). The global petrochemical market is valued at over USD 600 billion; India's domestic market is approximately USD 230 billion.

  • Ethylene: most important primary petrochemical; derived from steam cracking of naphtha or ethane
  • Polypropylene (PP): used in packaging, automotive parts, textiles
  • PTA (Purified Terephthalic Acid): feedstock for polyester fibre and PET (used in bottles)
  • PVC (Polyvinyl Chloride): used in pipes, window frames, cables, flooring
  • ABS (Acrylonitrile Butadiene Styrene): used in LEGO bricks, automotive dashboards, electronics casings
  • India imports ~7–8 million tonnes of polymers annually; domestic production covers ~60% of demand

Connection to this news: India's import dependence for specific polymers (notably polycarbonates, ABS, specialty resins) makes these 40 products particularly vulnerable to Hormuz disruptions — the duty exemption directly targets this import-dependent segment.

Strait of Hormuz: Strategic Importance and the 2026 Crisis

The Strait of Hormuz is a 33-km-wide waterway between Iran and Oman at the entry to the Persian Gulf. It is the world's most strategically critical maritime chokepoint: ~20% of global crude oil and petroleum products and ~30% of global LNG pass through it. The 2026 crisis began when Iran's Islamic Revolutionary Guard Corps (IRGC) prohibited vessel passage through the strait following US-Israel military action. India's crude oil imports from the Gulf (Saudi Arabia, UAE, Kuwait, Iraq, Iran) represent 40–50% of its total oil import basket. For certain chemicals, India's Hormuz-linked import share exceeds 80%.

  • Strait of Hormuz narrowest point: ~33 km; shipping lanes: 2 km wide each direction
  • Major Hormuz exporters: Saudi Arabia, Iran, UAE, Kuwait, Iraq, Qatar
  • LNG: Qatar is the world's second-largest LNG exporter; almost all its shipments pass through Hormuz
  • Alternative routing: Suez Canal, Cape of Good Hope — adds 7–15 days and significant fuel costs
  • India's strategic petroleum reserve (SPR): ~5.3 million metric tonnes (capacity covers ~9 days of imports)
  • The 2026 crisis is described as the largest energy supply disruption since the 1970s oil embargo

Connection to this news: Hormuz closure drives up landed cost of petrochemical feedstocks in India; the duty exemption partially offsets the freight and price premium caused by route disruptions and global supply tightness.

Role of Customs Duty in Industrial Policy

Customs duty serves dual purposes: revenue generation and industrial protection. When domestic industry needs protection from cheaper imports, the government raises BCD. When domestic industry needs affordable inputs and domestic production is insufficient, the government reduces BCD. India has deployed this lever across multiple sectors: edible oils (duty cuts during 2021-23 inflation), pulses (duty cuts 2016–18), steel (duty hikes 2022 to protect domestic steelmakers), and now petrochemicals (zero duty 2026). This flexible use of customs duty reflects India's calibrated industrial policy approach — protecting mature industries while supporting input-dependent downstream sectors.

  • Section 25, Customs Act 1962: Central Government may exempt any article from customs duty via Official Gazette notification
  • Customs Tariff Act 1975: provides the schedule of BCD rates (amended by Finance Act annually)
  • Custom duty notifications: "Category 1" (permanent, unlimited) vs "Category 2" (temporary, time-bound)
  • The April 2 notification is a Category 2 time-bound exemption with a sunset of June 30, 2026
  • WTO commitments: India's bound rates on most chemicals are 40%; the applied BCD was 2.5–5%; the current zero-duty is well within India's WTO commitments

Connection to this news: The 40-product exemption demonstrates the government's use of the Customs Act's executive notification power as a fast-response industrial policy tool — no parliamentary vote needed, effective immediately.
