Customs Duty Exemption on Petrochemicals

The Government of India has announced a full customs duty exemption on 40 critical petrochemical products until 30th June 2026. This decision has been taken to address cost pressures and supply chain disruptions caused by ongoing geopolitical tensions in West Asia.

What are Petrochemical Products?

Petrochemical products are fundamental chemical building blocks derived from petroleum or natural gas. They act as raw materials for nearly 95% of manufactured goods, including plastics, pharmaceuticals, textiles, and even renewable energy components.

These products are broadly classified into three main groups based on chemical structure: Olefins, BTX Aromatics, and Syngas.

Major Categories of Petrochemicals

1. Olefins (Alkanes)

Olefins are the most widely produced petrochemicals and are primarily used in plastics and synthetic rubber production.

Ethylene is the key raw material for polyethylene (PE), which is used in packaging, bottles, and films. Propylene is used to produce polypropylene (PP), which is widely used in automotive parts, textiles, and heat-resistant containers. Butadiene is essential for manufacturing synthetic rubber, particularly for tyres and industrial components.

2. BTX Aromatics

BTX refers to benzene, toluene, and xylenes, which are ring-shaped hydrocarbons used in high-value industrial products. Benzene is used in textiles and industrial packaging. Toluene is commonly used as a high-octane fuel additive and solvent in paints. Xylenes are used in producing PET (polyethylene terephthalate), which is used for water bottles and polyester clothing.

3. Synthesis Gas (Syngas)

Syngas is a mixture of carbon monoxide and hydrogen used to produce fertilizers and chemical intermediates.

Ammonia, derived from syngas, is the foundation of nitrogen-based fertilizers like urea and plays a critical role in global food security. Methanol is a versatile chemical used as a solvent, fuel additive, and in the production of formaldehyde and plastics.

Economic and Strategic Importance

Petrochemicals account for approximately 12–14% of global oil demand, making them a rapidly growing segment of the energy sector. Production is concentrated in regions with access to low-cost feedstocks such as ethane from natural gas or naphtha from crude oil refining.

Objective and Coverage of the Customs Exemption

The exemption provides temporary and targeted relief to downstream industries by ensuring the availability of key inputs such as methanol, styrene, toluene, and anhydrous ammonia. These inputs have seen price increases due to geopolitical disruptions, including conflicts in West Asia.

This measure primarily benefits industries such as plastics, textiles, pharmaceuticals, automotive components, and chemicals, helping stabilize production costs and prevent inflation in consumer goods.

What is Customs Duty?

Customs duty is a tax imposed on goods imported into or exported from a country, governed in India by the Customs Act 1962 and the Customs Tariff Act 1975. It serves not only as a revenue source but also as a tool to protect domestic industries, regulate trade, and ensure compliance with safety and environmental standards.

Types of Customs Duties

Customs duties are broadly classified into ad valorem duties (based on percentage of value), specific duties (based on quantity), and compound duties (a combination of both). Additional duties include anti-dumping duties, countervailing duties, and protective duties.

The duty is calculated on the assessable value, which is typically based on the Cost, Insurance, and Freight (CIF) method. The formula used is:
Customs Duty = Assessable Value × Duty Rate.

Recent Reforms

Recent reforms under the Union Budget 2026–27 include a reduction in customs duty on goods imported for personal use from 20% to 10%. Additionally, customs duty has been fully exempted on 17 cancer drugs and medicines for 7 rare diseases, reflecting a focus on healthcare affordability.

Conclusion

In conclusion, the customs duty exemption on petrochemicals is a strategic response to global supply chain disruptions and rising input costs. Petrochemicals themselves are vital to modern industry, forming the base of plastics, fertilizers, textiles, and pharmaceuticals.
