Nepal-India Treaty of Trade & Duty-Free Access Explained

India is by far Nepal's largest trading partner, absorbing roughly two-thirds of Nepal's exports and supplying the majority of its imports. Because Nepal is landlocked, almost all of its overseas trade also physically passes through India. This makes the bilateral trade framework the single most important economic agreement Nepal has, shaping what Nepali exporters can sell across the border and on what terms.

The relationship rests on two linked instruments: the Treaty of Trade, which governs tariffs and market access, and the Treaty of Transit, which guarantees Nepal's right to move goods to and from the sea through Indian territory and ports. The current Treaty of Trade was first signed in its modern form in 1996 (2053 Bikram Sambat) and comprehensively revised on 27 October 2009 (11 Kartik 2066 BS).

The treaty's defining feature is that market access is largely non-reciprocal, meaning India offers Nepal more generous terms than Nepal offers India. This reflects both India's much larger economy and Nepal's status as a least developed country (LDC). For students of trade policy and for exporters planning shipments, understanding which article applies to which product is essential, because the rules for a raw agricultural product differ sharply from those for a factory-made good.

The phrase 'unilateral' or 'non-reciprocal' duty-free access describes concessions one country gives without demanding equal concessions in return. Under Article V of the Treaty of Trade, India agrees to admit Nepalese manufactured articles free of basic customs duty and, in principle, without quantitative restrictions, on a non-reciprocal basis. In plain terms, qualifying Nepali factory goods can enter India duty-free, but Nepal is not obliged to open its market to Indian manufactures on identical terms.

This is a deliberate development concession. Nepal, as an LDC and a landlocked neighbour, is given preferential entry into the roughly 1.4-billion-person Indian market to help it industrialise and narrow a chronic trade deficit. The concession is powerful on paper, but it is conditional: goods must satisfy rules of origin, and a handful of 'sensitive' items are capped by quota.

It is important not to confuse duty-free with barrier-free. Even where basic customs duty is waived, Nepali exports still face Indian internal taxes on a non-discriminatory basis, quality and standards checks, laboratory testing requirements, and periodic non-tariff barriers at the border. Exporters and Nepali officials have repeatedly flagged these procedural hurdles as the practical limit on how much value the duty-free promise delivers.

Primary products are handled separately from manufactures. Under Article IV of the treaty, the two governments agree, on a reciprocal basis, to exempt from basic customs duty and from quantitative restrictions the import of mutually agreed primary products. Unlike the manufactures regime, this concession runs both ways: agreed primary goods flow duty-free in each direction.

The Protocol to Article IV defines the covered list. It broadly includes agriculture, horticulture, floriculture and forest produce, along with minerals that have not undergone processing, and specified items such as rice, pulses and flour, timber, jaggery (gur), animals, birds and fish, honey and beeswax, and raw wool and goat hair. Because it covers substantially all unprocessed goods, this article functions as a genuine free-trade arrangement for the primary sector.

The distinction between a 'primary product' and a 'manufactured article' therefore has real financial consequences. A product that has undergone processing crosses out of the Article IV list and must instead qualify under the stricter Article V rules of origin. Exporters of items like herbs, cardamom, ginger, tea or timber should confirm the correct classification before shipping, because it determines whether the simpler reciprocal regime or the value-addition test applies.

For manufactured articles, duty-free access is not automatic. Article V and its associated protocol impose rules of origin designed to ensure that only goods genuinely made in Nepal, rather than simply trans-shipped through it, receive the preference. A Nepali factory good must satisfy a twin test to qualify.

The first requirement is value addition: the manufacturing process in Nepal must add at least 30% of value measured at the ex-factory price. Put another way, the total value of materials, parts or produce sourced from non-contracting parties or of undetermined origin must not exceed 70% of the FOB (free-on-board) price of the finished article. The second requirement is a substantial transformation test: the manufacturing must result in a change of tariff classification at the four-digit level of the Harmonized System (HS) code, so the finished product falls under a different tariff heading than its imported inputs.

Both conditions must be met together, and the goods must be accompanied by a certificate of origin issued by an authorised Nepali agency. Nepali exporters and trade experts have long argued that the 30% threshold and the 4-digit change are onerous for a small economy that imports most of its raw materials, and Nepal has repeatedly sought to lower the value-addition bar (for example to 25%) in line with the more relaxed rules of origin that WTO members extend to least developed countries. As of 2026 the 30% requirement remained in force.

Although Article V promises access 'without quantity restriction', India carved out four sensitive products where domestic industry pressed for protection. These items receive duty-free treatment only up to an annual quota; volumes above the cap face India's normal, non-preferential tariffs. The restrictions were formalised during the treaty revisions of the early 2000s and carried into the 2009 text.

The four quota items are vegetable ghee (vanaspati), acrylic yarn, copper products and zinc oxide. The commonly cited annual ceilings are 100,000 metric tonnes for vegetable ghee, 10,000 metric tonnes each for acrylic yarn and copper products, and 2,500 metric tonnes for zinc oxide. Nepal has repeatedly asked India to scrap these quotas, and India has repeatedly declined, most notably rejecting such a request in 2019.

Separately, a short list of goods is excluded from preferential entry altogether, regardless of origin. Under the treaty's annexure, alcoholic liquors and beverages (other than industrial spirits), perfumes and cosmetics carrying non-Nepalese or non-Indian brand names, and cigarettes and tobacco do not receive duty-free access. The treaty also contains a safeguard mechanism: where a surge of imports causes or threatens serious injury to domestic producers, either side may consult through the Joint Committee and, after the prescribed consultation period, apply remedial measures.

Because Nepal has no coastline, market access alone is meaningless without a guaranteed route to the sea. The India-Nepal Treaty of Transit, first signed in 1978, secures Nepal's right to move its overseas trade through Indian territory and ports. It is a separate agreement from the Treaty of Trade and is renewed on a seven-year cycle. The concept of transit rights for Nepal dates back to the 1950 Treaty of Trade and Commerce, which recognised Nepal's right of commercial transit through Indian territory and ports.

The treaty and its protocol grant Nepal 'traffic in transit' facilities, including trans-shipment, warehousing, and the breaking of bulk, along with designated transit routes and port facilities. Nepal's primary gateway to the ocean is the Kolkata/Haldia port complex in West Bengal, which handles the bulk of its sea-borne freight. Since 2016, Visakhapatnam port on India's east coast has been available as an additional gateway, and Nepal has also negotiated access to Dhamra port.

Transit arrangements have steadily liberalised. A letter of exchange concluded on 13 November 2025 expanded rail-freight movement by extending corridors such as Kolkata-Jogbani, Kolkata-Nautanwa (Sunauli) and Visakhapatnam-Nautanwa, and by allowing a far wider range of third-country cargo to move by rail through checkpoints like Biratnagar. Previously, only a narrow set of commodities such as coal, clinker, cement and fertiliser could be railed in. Integrated Check Posts (ICPs) at points including Birgunj and Biratnagar serve as the main logistics hubs where transit and customs formalities are consolidated.

The Treaty of Trade remains in force for a period of seven years and is automatically extended for further seven-year periods unless either government gives written notice of termination. This auto-renewal clause has real consequences: the treaty most recently rolled over automatically in November 2023 without renegotiation, which Nepali commentators criticised as a missed chance to update outdated rules of origin and remove the quotas. Under the seven-year cycle, the next formal renewal window falls around 2030, though both sides can revisit the text at any time by mutual agreement.

For Nepal, the central grievances are well documented: the 30% value-addition requirement and the 4-digit tariff-change rule are hard for a small, import-dependent manufacturing base to meet; the four quota items limit some of Nepal's most competitive exports; and non-tariff barriers, quarantine and testing delays erode the duty-free advantage in practice. Nepal has also pressed for smoother transit and for the treaty to better reflect its LDC status.

For exporters and students, the practical takeaway is clear. Confirm whether a product is a primary product (Article IV, reciprocal duty-free) or a manufactured article (Article V, subject to rules of origin); check whether it is one of the four quota items or on the excluded list; secure a valid certificate of origin; and plan logistics around the transit corridors and ICPs. Because provisions, quotas and corridors are periodically amended, always verify current terms against the Nepal Trade Portal and the Ministry of Industry, Commerce and Supplies before shipping.
