Customs duty historically emerged as a customary obligation where merchants entering a kingdom would present a gift to the sovereign. Over centuries, this informal practice evolved into a formal tax on goods entering or exiting a territory. The term ‘customary’ reflects this deep historical lineage, tracing back to ancient trade throughout the Vedic era, when charges were levied on goods moving between regions. In India, the modern construct of customs duty took shape under colonial rule.
During the British period, administrative and revenue functions were institutionalised. The first Board of Revenue in Calcutta was established in 1786, followed by the Board of Trade in 1808. A uniform tariff act, applied across British India, was introduced in 1859, imposing a general import duty rate of ten per cent. Pressure from British textile producers led to a reduction of the rate to seven and a half per cent in 1864. The Sea Customs Act of 1878 created a separate legal framework for maritime trade. Although import duties were briefly abolished in 1882, they were reinstated in 1894 at five per cent under the Indian Tariff Act. That same year, the colonial administration introduced an excise duty on indigenous cotton goods, which remained deeply unpopular until its repeal in 1925. Subsequently, import duty rates rose again to seven and a half per cent. The Land Customs Act followed in 1924, and air transport was later regulated through rules under the Indian Aircraft Act of 1911.
Following independence, India consolidated its customs legislation. The Customs Act of 1962 replaced earlier statutes governing land, sea, and air trade, creating a unified legal framework for modern customs administration. The act defines key provisions on duty levy, classification, offences, penalties, and procedural aspects, marking the foundation of the current customs law in India.
origins and evolution of customs duty
Customs duty as known today traces its origin to colonial administrative reforms and international trade pressures. British manufacturers, intent on distributing cotton textiles in Indian markets, successfully lobbied for tariff reductions on coarser cotton varieties, facilitating their imports. Trade policy became intertwined with imperial economics. The new uniform tariff regime imposed regulated duty across the subcontinent, but exemptions and preferential rates were granted strategically to benefit British trades. Legislative reforms such as the Sea Customs Act and Land Customs Act formalised jurisdictional definitions and territorial enforcement.
The era also witnessed the emergence of tariff classification systems and valuation standards. As early as the nineteenth century, the classification of goods and consistent duty rates became integral to customs law enforcement. British courts and Indian legislative authorities contributed to evolving legal interpretations concerning the charging section, taxable event, classification, valuation, and exemptions. This historical evolution laid the groundwork for statutory frameworks introduced post‑independence.
world trade organisation and india’s integration
The transition from the General Agreement on Tariffs and Trade to the World Trade Organisation took effect on January 1, 1995. The WTO emerged as the permanent institutional successor to GATT, headquartered in Geneva. As the third largest intergovernmental body in finance and trade (after the World Bank and IMF), the WTO became the legal and institutional cornerstone of the multilateral trading system. It provides a standing forum for trade negotiations, dispute resolution mechanisms, and rules governing international commerce.
India’s accession to the WTO required compliance with multilateral commitments across goods, services, and intellectual property. WTO’s guiding principles include trade without discrimination via Most Favoured Nation and national treatment rules, transparency in tariffs and services regimes, predictable and growing market access, promotion of fair competition, and special and differential treatment for developing countries. India adopted reforms aligning tariff rates with bound commitments, phased import liberalisation, and regulatory transparency.
Under trade‑related aspects of intellectual property rights (TRIPS), India agreed to transition from process patents to product patents for pharmaceuticals, chemicals, and food products, effective January 1, 2005. A standard patent and copyright were established. Agricultural hybrid seeds’ patent protection was not adopted. India retains rights for compulsory licensing to ensure access, supply adequacy, and prevention of excessive pricing.
World Customs Organisation and global coordination
The World Customs Organisation (WCO) plays a pivotal role in shaping and standardising international customs practices to promote smoother and more efficient global trade. As a unique intergovernmental organization, the WCO is committed to improving the effectiveness and efficiency of customs administrations worldwide. It achieves this through the development of international instruments, guidelines, and tools aimed at modernising customs procedures, promoting compliance, and strengthening cooperation among member states.
One of the WCO’s most notable contributions is the Harmonised Commodity Description and Coding System, commonly known as the Harmonised System (HS). This system serves as the foundation for the classification of traded products and is used by over 200 countries and economies. It ensures that goods are classified consistently and accurately, thus enabling fair taxation, correct tariff application, and accurate trade statistics. The regular revisions of the HS ensure that the classification remains up to date with the changing nature of international trade, including technological advancements and the emergence of new products.
Another significant framework developed by the WCO is the Revised Kyoto Convention (RKC), which provides a comprehensive set of guidelines for modern and efficient customs procedures. The RKC promotes simplified and harmonised customs processes through the use of risk management techniques, the adoption of automation, and cooperation between customs authorities and trade stakeholders. Its implementation allows customs administrations to process goods more quickly and efficiently while maintaining high levels of control and compliance.
Scope and coverage of customs law
The Customs Act of 1962 extends across the whole of India, and as amended effective 29 March 2018, includes extra‑territorial application for offences committed outside India by any person. That extension applies strictly to offences and contraventions under the act, not to ordinary levy provisions. The principle of extra‑territorial scope was affirmed by the Supreme Court in Union of India v. Mohit Minerals, where legislative power was held valid in extending jurisdiction for offences beyond national borders. The Act requires customs duties to be levied at rates specified under the Customs Tariff Act, 1975, or other applicable law. Import duty applies to almost all imported items, while export duty is imposed only on a few select goods where India holds a dominant global position. Imports carried out by the central or state government are generally subject to customs duty unless an explicit exemption is provided through notifications.
The Customs Act empowers the central government to formulate policies regarding imports and exports, impose restrictions or prohibitions, and regulate the movement of goods across borders in the interest of national security, public order, or economic stability. While the levy of customs duty is generally confined to goods crossing the territorial boundaries of India, its enforcement provisions may extend beyond the country’s borders in cases involving smuggling, evasion, or other customs-related offences. The Directorate of Revenue Intelligence (DRI) plays a significant role in such cross-border investigations and enforcement.
The term “India” under the Act includes the territorial waters, continental shelf, exclusive economic zone (EEZ), and seabed areas up to the extent recognized under the United Nations Convention on the Law of the Sea (UNCLOS). This interpretation ensures that offshore exploration and production activities involving import or export of goods, such as machinery or crude oil, are also brought within the ambit of customs legislation. However, it is important to differentiate between areas where duties are levied and areas where enforcement can occur. The power to enforce customs law outside Indian territory does not automatically imply the power to levy customs duty outside territorial jurisdiction.
Additionally, the customs framework provides for advance rulings, warehousing, drawback schemes, and bonded logistics, which facilitate international trade while ensuring compliance with revenue and security considerations. Importers and exporters must adhere to the classification of goods as per the Harmonised System (HS) adopted under the Customs Tariff Act, and must determine the applicable rate of duty, exemptions, valuation rules, and procedural formalities accordingly. The dynamic nature of customs regulations requires businesses to stay updated with frequent changes in law, notifications, circulars, and judicial pronouncements to mitigate compliance risks and avoid penalties.
Overview of the Customs Act and related legislation
The Customs Act, 1962, serves multiple purposes beyond revenue collection. It regulates imports and exports, protects domestic industry against unfair practices such as dumping, and supports foreign trade and foreign exchange laws. The act outlines levy and collection mechanisms, procedural requirements, prohibitions, offences, penalties, appeal processes, and powers of customs authorities. The Customs Tariff Act, 1975 complements it by providing schedules of classification and rates for imports (Schedule 1) and exports (Schedule 2), along with provisions for additional duties, protective duties, anti‑dumping duties, and preferential tariff treatment. Under section 156 of the Customs Act, the central government may frame rules to implement the act’s objectives, and these regulations have the force of law as affirmed in judicial precedents. Notifications issued under specific sections grant exemptions or prohibit specified goods. Additionally, the customs board issues circulars under section 151A to ensure uniformity in classification and duty levy across customs offices. The customs board’s official manual, updated as of 31 December 2023, consolidates procedures and circular instructions.
Functions of the customs department
Customs authorities in India perform critical tasks, including collecting duties on imports and exports, enforcing compliance with provisions governing cargo, baggage, postal items, and managing arrival and departure procedures. They act as an enforcement agency for prohibitions under customs, foreign trade, and foreign exchange laws, and work to prevent smuggling and narcotics trafficking. Customs officers manage international passenger clearance and coordinate regulatory oversight across importers, exporters, carriers, port and airport authorities, postal agencies, banks, and various government units. India is modernising customs through automation such as electronic data interchange, risk‑based assessment, and adoption of international conventions like HS classification, valuation methods, and simplified procedural standards under the Revised Kyoto Convention.
Common aspects of Customs and CGST
Customs law and central goods and services tax law are administered under the unified direction of the same authority, drawing its veryy power from the constitution. Both statutes share a hierarchical organisational structure, with similar roles and rank designations from the top to the assistant commissioner level. Tariff classification across both systems relies on Harmonised System codes and prioritises identical classification principles. Assessable value in both domains is principally based on transaction value, with related person determination, piercing of corporate veil concepts, refund and interest provisions, grounds for raising demand or recovery, and penalties. Both statutes allow partial or full duty or tax exemptions under specified conditions. Provisions for search and seizure, arrests,, and prosecution of offences exist under both laws. The mechanism for advance rulings, appellate structure, and procedural redressal bears a strong similarity. These parallel provisions facilitate consistency for businesses operating under both regimes and reduce complexity in compliance strategy.
Extension of time limits due to COVID-19
The Supreme Court took suo motu cognisance of difficulties faced by litigants during the Covid‑19 pandemic and passed several orders extending statutory limitation periods. The first order dated 23 March 2020 directed that, for all judicial or quasi‑judicial proceedings under general or special laws, the period from 15 March 2020 to 14 March 2021 stood excluded when computing limitation. The balance period remaining as of 15 March 2021 became available from that date. This order applies to all filings, including suits, appeals, applications, and tribunal matters.
Subsequent resurgence of infections prompted the revival of the extension. The Supreme Court, in its order of 23 September 2021, reinstated relief and extended the exemption until 2 October 2021. Ultimately, a later order in early 2022 restored the extended exemption period up to 28 February 2022. The balance period remaining as of 3 October 2021 became available from 1 March 2022. In cases where limitation had expired between 15 March 2020 and 28 February 2022, a grace period of 90 days from 1 March 2022 was granted even if the actual balance period was shorter; if longer, that longer period applied.
These directions are binding on courts and tribunals and by extension apply to tax proceedings, including customs show‑cause notices, adjudications, and appeals. As a result, timelines under the Customs Act and the Customs Tariff Act between 15 March 2020 and 28 February 2022 were treated as excluded for computation of limitation in enforcement and recovery matters.
Amendments made by Finance Act, 2023
Finance Act, 2023,, introduced two key changes to the Customs Act effective 1 April 2023. First, subsection (4A) of section 25 was amended to clarify that the two‑year sunset clause on conditional exemption notifications no longer applies to exemptions granted under multilateral or bilateral trade agreements, international obligations, constitutional authorities, foreign trade policy schemes, long‑term central government schemes, re‑imports, temporary imports, gifts, personal baggage, and IGST/compensation cess cases other than customs duty under section 12.
Second, section 65A was inserted to regulate manufacture or operations in bonded warehouses when goods on which IGST and compensation cess have been paid are used for in‑bond manufacture. Under section 65A,, importers must file a bill of entry for home consumption at the warehouse entry and pay IGST and cess upfront. The existing duty (basic customs duty) continues to be payable only when goods are cleared for home consumption. Regulations under new clause 157(2)(c) empower authorities to prescribe the manner and conditions for the payment and removal of goods under 65A.
In addition ,,schedules under the Customs Tariff Act were amended to revise duty rates for select goods, rationalise tariff structure, and redefine project imports coverage from 1 April or 1 May 2023 as notified. Settlement commission timelines were also tightened. Orders under section 127C(5) must now be passed within nine months (extendable by three months) from the end of the application month. Failing this, the settlement proceedings lapse and the pending application must be disposed of as if no settlement had been applied for.
Foreign Trade Policy 2023 effective from 1 April 2023
The Foreign Trade Policy 2023 came into force on 1 April 2023. It sets out export‑import regulations, incentive schemes, licensing procedures, and procedural norms under the Handbook of Procedures 2023. This policy integrates with customs regulations to provide export promotion schemes, duty exemptions, and facilitation services. While specific sections are extensive, key features include rationalised incentives under export promotion schemes, simplified licensing for imports and strategic sectors, attention to MSMEs and green exports, and alignment with WTO and WCO frameworks.
Nature of customs duty
Customs duty is levied under the union list of the constitution and derives constitutional authority from entry 83. Section 12 of the Customs Act, 1962, prescribes the levy of duties on goods imported into or exported from India, based on rates set in the Customs Tariff Act, 1975. The act applies uniformly to imports made for home consumption or temporarily imported goods subject to exemptions. Even government imports are taxable unless a specific exemption notification applies. Duty categories include basic customs duty, additional duties such as countervailing duty, protective duties, preferential rates, anti‑dumping duties, and social welfare surcharge. The customs tariff schedules classify goods and set differentiated rates, with procedures regulated through rules, notifications, and circulars issued by customs authorities.
Taxable event for import duty
The taxable event for import duty is triggered when goodcustoms barrierer and are cleared for home consumption. Supreme Court rulings have clarified that merely landing in Indian territorial waters does not trigger duty. In Kiran Spinning Mills v. Collector of Customs, the court held that the taxable event occurs only when goods cross the customs barrier and not upon entering territorial waters or physical landing in India. In Garden Silk Mills Ltd v. UnionIndiae court held that import commences at entry into territorial waters but is completed when goods become part of the mass of goods within India and the bill of entry for home consumption is filed. In cases where goods remain in a bonded warehouse, import is triggered only upon removal from the warehouse for home consumption, as affirmed by the SC in UOI v. Apar P Ltd and applied in the Kiran Spinning Mills ruling. Valuation and applicable duty rate are determined by the later of the vessel’s entry inward date or bill of entry presentation date, as upheld in landmark precedents like Bharat Surfactants and subsequent Supreme Court orders.
Taxable event for export duty
Export liability arises when goods cross Indian territorial waters bound for a place outside India. In Rajindra Dyeing and Printing Mills v. Union of India, the Supreme Court held that export completes when goods exit territorial waters; sinking within these waters nullifies export and duty drawback eligibility. Similarly, in Sun Exports and other judgments, the court affirmed that export completes upon crossing into international waters and transfer of property to the foreign buyer. Advance duty collection before physical crossing of waters does not establish the taxable event, though permitted by regulations.
Territorial waters and customs waters in customs law
Territorial waters extend up to twelve nautical miles from the baseline along the Indian coast and form an integral part of India’s sovereign territory under the Maritime Zones Act, 1976. Within this maritime belt, India exercises complete sovereignty, not only over the waters themselves but also over the airspace above and the seabed and subsoil beneath. These rights are similar to those exercised over the land territory of the country.
Beyond the territorial waters, and stretching up to 200 nautical miles from the baseline, lies the Exclusive Economic Zone (EEZ). In the EEZ, India does not possess full sovereignty but enjoys sovereign rights to explore, exploit, conserve, and manage natural resources—both living and non-living—of the waters superjacent to the seabed, the seabed itself, and its subsoil. These rights also include jurisdiction over the establishment and use of artificial islands, marine scientific research, and protection of the marine environment. However, the EEZ remains subject to certain internationally recognized freedoms, including the freedom of navigation and overflight, as codified under the United Nations Convention on the Law of the Sea (UNCLOS), to which India is a party.
Section 2(28) of the Customs Act, 1962, defines ‘Indian customs waters’ as the waters extending up to the limit of the Exclusive Economic Zone and includes any bay, harbour, creek, or tidal river. As a result, the jurisdiction of customs authorities is not confined merely to the twelve nautical miles of territorial waters but extends up to 200 nautical miles into the EEZ. Customs officers are empowered to exercise various powers, such as arrest, search, seizure, and investigation, within this extended maritime area. This broad jurisdiction ensures robust enforcement of customs and fiscal laws, particularly in matters involving smuggling, illegal trade, and unauthorized resource exploitation.
The distinction between territorial waters and customs waters is therefore crucial. While territorial waters fall under India’s absolute sovereignty, Indian customs waters represent a broader zone where the state exercises jurisdiction primarily for the enforcement of revenue and trade laws. This layered maritime regime reflects the balance between sovereign control and international legal obligations in India’s approach to maritime governance.
Conclusion
Customs law in India rests on centuries of tradition that evolved into a modern statutory regime under colonial administration. Early taxation on trade gradually gave way to formal enactments such as the Sea Customs Act, Land Customs Act, and ultimately the unified Customs Act of 1962, aligned with the Customs Tariff Act of 1975. Over time, this framework has been refined to address changing economic, trade, and security demands.
India’s adherence to global trade frameworks such as the World Trade Organisation (WTO) and World Customs Organisation (WCO) has infused international standards into domestic practice. Harmonised commodity classification, valuation norms, and simplified customs procedures now reflect multinational protocols. India’s Foreign Trade Policy, most recently refreshed in 2023, integrates customs mechanisms with trade‑promotion schemes and procedural incentives.
