Customs Duty in India

Customs duty is a tax the government charges on goods moving across India's borders, mostly on imports (goods coming in) but sometimes on exports (goods going out) too. It is collected at ports, airports and land check-posts by the Customs department, which works under the Central Board of Indirect Taxes and Customs (CBIC). When you read that "the government cut the import duty on edible oil", it means this tax was reduced.

Why does it exist?

Customs duty does three jobs at once. First, it is a source of revenue for the government. Second, it protects Indian producers: if a foreign good is far cheaper than what Indian farmers or factories can make, a duty raises its price so Indian producers can still compete. Third, it is a quick tool to manage prices at home.

If the price of something is rising too fast because supply is short, the government can cut the duty on its import so more of it can come in cheaply, and prices cool down. Think of the duty as a gate: raising it slows down imports, lowering it lets more in.

Where does the power come from?

Under the Constitution, only Parliament (the Union) can make laws on duties of customs; this is in the Union List (List I) of the Seventh Schedule. The main law is the Customs Act, 1962, and rates are fixed under the Customs Tariff Act, 1975. The Finance Ministry issues a notification each time a rate is changed, so a rate cut like this one takes effect the moment the notification is published, without needing a new law each time.

How is the "effective" rate built up?

The rate you see quoted in the news, such as "16.5% effective duty", is usually more than just the Basic Customs Duty (BCD). On top of BCD, the government can add:

• The Agriculture Infrastructure and Development Cess (AIDC), introduced in the 2021 Budget to fund farm infrastructure. It is charged as a percentage on top of the value of the goods, but it is designed so that when combined with the cut in BCD, the total tax the importer pays does not rise; it is meant to relabel part of the duty as a cess earmarked for agriculture spending, not to add a new burden.
• A social welfare surcharge, a small additional charge (10% of the BCD amount, unless exempted) used to fund social welfare schemes.

So the "effective duty" an importer actually pays is BCD plus these add-ons, and that is the number that changes when the government wants a bigger or smaller effect on the market. On edible oils, all three layers were cut together, but the gap between crude oil duty and refined oil duty was kept nearly the same, so refiners are not hurt while consumers still see lower prices.

Crude vs refined: why the gap matters

India imports both crude edible oil (which Indian refineries then process, package and sell) and refined edible oil (ready to use). If the duty gap between the two is small, importers would rather bring in cheap ready-made refined oil, and Indian refining units would run without enough raw material, hurting jobs and capacity utilisation in the domestic refining industry.

Keeping a wide gap, usually around 19 percentage points in recent years, gives refiners a price cushion so they keep importing crude and refining it in India (this is sometimes called effective rate of protection for the refining industry).

Commonly confused concepts

• Customs duty vs GST: Customs duty is charged only when goods cross the border, based on the Customs Tariff Act. GST (Goods and Services Tax) is charged on the sale of goods and services within India, including on imported goods once they clear customs. Both can apply to the same imported item, one after the other.
• BCD vs AIDC vs surcharge: BCD is the basic tax rate under the tariff schedule. AIDC and the social welfare surcharge are additional layers calculated on top, usually adjusted together with BCD so that the total effective duty moves in one clear direction (up or down), even though three different components are involved.

Issues, criticism and the way forward

Cutting import duty helps consumers by lowering retail prices, but it can hurt domestic oilseed farmers by pulling down the price they get when cheaper imported oil enters the market, especially if the cut coincides with the farmers' own harvest season. Because India imports well over half of the edible oil it consumes (mostly palm oil from Indonesia and Malaysia, and soybean and sunflower oil from South America, Ukraine and Russia), the government constantly balances consumer relief against the need to make oilseed farming profitable enough that farmers don't shift away from oilseeds towards other crops.

Experts and government reports (including the Economic Survey) have repeatedly flagged India's high dependence on edible oil imports as a food-security risk, and recommend raising India's own oilseed output as the more durable fix, rather than relying only on duty changes.

Concepts to Know

• Basic Customs Duty (BCD): The main tax rate charged on an imported good, fixed under the Customs Tariff Act, 1975.
• Cess: A tax collected for a specific, named purpose (here, agriculture infrastructure), kept separate from the government's general funds.
• Effective duty: The real, total tax an importer pays after adding all cesses and surcharges to the basic duty.
• Mandi: A wholesale market, usually regulated by a state Agricultural Produce Market Committee (APMC), where farmers sell their harvest.
