International Trade

Why this chapter matters for UPSC: India's foreign trade is a GS3 staple (trade deficit, export composition, dependence on imported oil and gold, labour-intensive exports) and its ports are a GS1 map staple (each major port, its coast, its hinterland, and the new names). Mains has asked why India became a net food exporter, about gold imports and the balance of payments, and why manufacturing failed to produce labour-intensive exports; Prelims (2026) asked about Sagarmala and the Vizhinjam port. In the 2026-27 NCERT reprint this is Chapter 8, "International Trade", with its tables updated to 2021-22 and the renamed ports. (Until October 2026 this site covered trade inside the transport chapter; it now has this page of its own, and ch. 10 covers transport and communication.)

Contemporary hook: In 2025-26 India's merchandise exports were US$ 441.78 billion and imports US$ 774.98 billion, a goods deficit of US$ 333.19 billion, partly offset by a surplus in services (exports US$ 418.31 billion against imports of US$ 204.42 billion). The WTO puts India's 2025 goods exports at 1.7% of world exports, 19th in the world, against 2.8% of imports, 9th: NCERT's "as low as one per cent" has grown but still makes India a bigger buyer than seller. The USA is the largest destination for India's exports and China the largest source of its imports.

🧠 First Principles — Read This First

India imports more than it exports, and the gap is mostly energy, metals and machines. NCERT's tables show the value of imports "continued to be higher than that of exports" every year, and its account of the import basket explains why: food imports gave way after the Green Revolution, but the 1973 oil crisis raised the cost of petroleum, which is both fuel and industrial raw material, and the import of capital goods, non-ferrous metals, pearls and precious stones, gold and silver grew with industrialisation and rising living standards. On the export side, manufactured goods dominate (engineering goods most of all), traditional agricultural exports have declined against tough competition, and China and other East Asian countries are India's main competitors. Trade in goods is therefore in deficit; trade in services, which NCERT's chapter does not cover, is in surplus.

Ports are gateways, and each has a hinterland. Most of India's trade moves by sea, with a smaller share by air and a small portion by land to Nepal, Bhutan, Bangladesh and Pakistan. A port's hinterland is the area it serves, and hinterlands overlap and change: the Konkan railway widened Mormugao's, and the partition took away Karachi and Chittagong, so Kandla and the Haldia-Diamond Harbour area were built to replace them. The second half of the chapter is a tour of the major ports in that light: where each is, what it handles, and whom it serves.

PART 2 — Concepts & Narrative

The Changing Pattern of India's Trade

International trade is mutually beneficial, because no country is self-sufficient. NCERT says India's trade "has undergone a sea change" in volume, composition and direction, and that although its share of world trade is "as low as one per cent of the total volume", it plays a significant role in the world economy. In 1950-51 India's external trade was worth ₹1,214 crore (exports ₹606 crore and imports ₹608 crore); it rose to ₹44,29,762 crore in 2016-17 (2021-22 text) and ₹77,19,796 crore in 2020-21 (2026-27 text). NCERT gives three reasons: the momentum of manufacturing, the government's liberal policies and the diversification of markets. Imports have exceeded exports throughout.

Composition of Exports

Between 2015-16 and 2021-22 (NCERT's 2026-27 tables) the shares of agriculture and allied products and manufactured goods in exports fell, while crude and petroleum products and other commodities rose; ores and minerals stayed roughly constant. The decline of traditional items is due to "tough international competition": among farm products, traditional exports such as cashew declined, while floricultural products, fresh fruits, marine products and sugar grew. Manufactured goods were still 67.8% of export value in 2021-22, with engineering goods showing significant growth; China and other East Asian countries are the main competitors, and gems and jewellery contribute a large share. (The 2021-22 text gave manufactures 73.6% in 2016-17 and named coffee among the declining traditional items.)

The 2025-26 figures continue the pattern: engineering goods (US$ 122.4 billion) are by far the largest export group, followed by petroleum products, whose value fell, and electronic goods, the fastest-growing major group (up 24.4% to US$ 48.0 billion).

Composition of Imports

India faced serious food shortages in the 1950s and 1960s, when foodgrain, capital goods, machinery and equipment were the main imports and the balance of payments was adverse "in spite of all the efforts of import substitution". After the 1970s foodgrain imports stopped with the Green Revolution, but the energy crisis of 1973 pushed up petroleum prices and the import bill; fertilisers and petroleum replaced foodgrains. Machinery and equipment, special steel, edible oil and chemicals make up much of the basket.

NCERT's import table shows petroleum rising (fuel was 31.6% of imports in 2021-22): it is used as fuel and as an industrial raw material, so it reflects the tempo of industrialisation and better living standards, and sporadic price rises add to it. Other major imports are pearls and precious and semi-precious stones, gold and silver, metalliferous ores and metal scrap, non-ferrous metals and electronic goods. NCERT asks why India imports edible oil though it is an agriculturally rich country, and which imports could be substituted at home.

Direction of Trade

India trades with most countries and blocs. NCERT's Table 8.6 shows imports by region, led by Asia and ASEAN (₹29,18,577 crore in 2021-22), followed by Europe, North America, Africa and Latin America. Most trade moves by sea and air, a small portion by land to Nepal, Bhutan, Bangladesh and Pakistan. NCERT also notes India's aim to double its share of world trade within five years, through import liberalisation, lower import duties, delicensing and the change from process to product patents. In 2025-26 the USA took the most of India's exports and China supplied the most imports; the UAE was second on both sides, and Russia, chiefly through crude oil, was the third-largest source of imports.

Sea Ports as Gateways of International Trade

India is surrounded by sea on three sides, and water gives a smooth, very cheap surface for transport when it is calm. India has a long seafaring tradition, with many ports whose names end in -pattan ("port"), and its west coast has more ports than its east coast. Ports became gateways of international trade after the Europeans arrived and the British colonised India, which created great variation in their size and the reach of their hinterlands. The British used ports as "suction points" for resources from their hinterlands, and railways linked local markets to regional, national and international ones until 1947. Independence was expected to reverse this, but partition took away two important ports, Karachi (to Pakistan) and Chittagong (to East Pakistan, now Bangladesh); to compensate, Kandla in the west and Diamond Harbour near Kolkata on the Hugli in the east were developed. Ports continued to grow, modernisation was opened to private entrepreneurs, and capacity rose from 20 million tonnes in 1951 to more than 837 million tonnes in 2016 (NCERT).

NCERT says India has 12 major ports and 200 minor or intermediate ports: the central government decides policy and regulates the major ports, and the State governments the minor ones; major ports handle the larger share of traffic. The Ministry of Ports, Shipping and Waterways now counts 14 major ports, 12 of them in operation (Vadhavan in Maharashtra and Galathea Bay in the Andaman and Nicobar Islands have been notified), and 200 non-major ports under State maritime boards. The Major Port Authorities Act, 2021, in force from 3 November 2021, turned the old port trusts into port authorities. The twelve operating major ports handled 914.73 million tonnes of cargo in 2025-26, up 7% on the year.

The Major Ports (NCERT)

West coast

• Deendayal (Kandla), at the head of the Gulf of Kachchh, was developed to serve western and north-western India and to relieve Mumbai. It is designed to receive large quantities of petroleum, petroleum products and fertiliser; an offshore terminal at Vadinar relieves pressure on it. (Renamed Deendayal Port with effect from 25 September 2017.) It handled the most cargo of any major port in 2025-26: 160.11 million tonnes.
• Mumbai is a natural harbour that NCERT calls "the biggest port of the country", close to the routes to the Middle East, the Mediterranean, North Africa, North America and Europe. NCERT describes it as 20 km long and 6-10 km wide, with 54 berths and the country's largest oil terminal, serving Madhya Pradesh, Maharashtra, Gujarat, Uttar Pradesh and parts of Rajasthan. By cargo, it was fifth among the major ports in 2025-26 (75.15 million tonnes).
• Jawaharlal Nehru Port at Nhava Sheva was developed as a satellite port to relieve Mumbai; NCERT calls it the largest container port in India. The port authority itself says it handles about 50% of the containerised cargo of the major ports.
• Mormugao, at the entrance of the Zuari estuary in Goa, is a natural harbour that gained importance after its remodelling in 1961 to export iron ore to Japan; the Konkan railway extended its hinterland (Karnataka, Goa, southern Maharashtra).
• New Mangalore, in Karnataka, exports iron ore and iron concentrates and handles fertilisers, petroleum products, edible oils, coffee, tea, wood pulp, yarn, granite and molasses; Karnataka is its main hinterland.
• Kochi (Cochin), at the head of Vembanad Kayal, the "Queen of the Arabian Sea", is a natural harbour close to the Suez-Colombo route, serving Kerala, southern Karnataka and south-western Tamil Nadu.

East coast

• Syama Prasad Mookerjee Port, Kolkata, on the Hugli, 128 km inland from the Bay of Bengal, was developed by the British and had the advantage of being the capital of British India. It has lost much significance to Visakhapatnam, Paradip and its own satellite, Haldia, and suffers from silt in the Hugli; its hinterland covers Uttar Pradesh, Bihar, Jharkhand, West Bengal, Sikkim and the north-east, and it serves the land-locked neighbours Nepal and Bhutan. (The Cabinet approved the new name on 3 June 2020.)
• Haldia, 105 km downstream of Kolkata, relieves congestion there and handles bulk cargo: iron ore, coal, petroleum, fertilisers, jute and cotton.
• Paradip, in the Mahanadi delta about 100 km from Cuttack, has, in NCERT's words, "the deepest harbour specially suited to handle very large vessels"; it was developed mainly to export iron ore and serves Odisha, Chhattisgarh and Jharkhand. It handled 156.45 million tonnes in 2025-26, second only to Deendayal.
• Visakhapatnam, in Andhra Pradesh, is a land-locked harbour connected to the sea by a channel cut through solid rock and sand; an outer harbour handles iron ore, petroleum and general cargo. Andhra Pradesh and Telangana are its hinterland.
• Chennai is one of the oldest ports on the east coast, an artificial harbour that NCERT dates to 1859; shallow water near the coast makes it unsuitable for large ships. Tamil Nadu and Puducherry are its hinterland.
• Kamarajar (Ennore), 25 km north of Chennai, was built to relieve Chennai; it is the only major port run as a company.
• V.O. Chidambaranar (Tuticorin) was also built to relieve Chennai and handles coal, salt, foodgrains, edible oils, sugar, chemicals and petroleum products. (Renamed in 2011.)

Airports

Air transport plays an important role in trade: it is fastest and suits high-value or perishable goods over long distances, but it is very costly and unsuited to heavy, bulky goods, which limits its share against ocean routes. NCERT lists 25 major airports (Annual Report 2016-17): Ahmedabad, Bengaluru, Chennai, Delhi, Goa, Guwahati, Hyderabad, Kolkata, Mumbai, Thiruvananthapuram, Srinagar, Jaipur, Calicut, Nagpur, Coimbatore, Cochin, Lucknow, Pune, Chandigarh, Mangaluru, Visakhapatnam, Indore, Patna, Bhubaneswar and Kannur. Its 2026-27 text adds that 73 unserved and underserved airports, including 9 heliports and 2 water aerodromes, had been operationalised under the UDAN scheme since 2017 (PIB, 2023). The Airports Authority of India now manages 137 airports: 24 international (including 3 civil enclaves), 10 customs airports, 80 domestic airports and 23 domestic civil enclaves.

PART 3 — UPSC Integration

Frames that score. For the trade deficit, use NCERT's import story (oil after 1973, capital goods, gold and stones) and quote the 2025-26 goods deficit with the services surplus. For export structure, NCERT's tables show manufactures dominant and traditional farm exports declining; add the 2025-26 rise of electronics. For ports, give each port's coast, its geographic setting (estuary, delta, gulf, backwater) and its hinterland, with the new name.

Exam Strategy

For Prelims: the renamed ports (Deendayal, Syama Prasad Mookerjee, V.O. Chidambaranar, Kamarajar); Visakhapatnam as the land-locked harbour; Vadinar (offshore terminal of Kandla); Mormugao on the Zuari; Kochi on Vembanad Kayal; Paradip in the Mahanadi delta; Haldia 105 km downstream of Kolkata; Ennore 25 km north of Chennai; the 1950-51 trade figure (₹1,214 crore); India's top partners in 2025-26.

For Mains: answer composition questions with NCERT's tables and the 2025-26 figures, and port questions with hinterlands.

Avoid: quoting NCERT's "Mumbai, the biggest port" as a current cargo ranking (Deendayal and Paradip handle more); mixing WTO's export and import ranks; and treating the 2025-26 Quick Estimates as final.
