Understand Introduction to the Customs Act, 1962
Customs duty is a tax on goods crossing India's border. It is levied when goods are imported into India or exported from India. Its aims are to raise revenue, regulate trade, protect domestic industry and check the entry of harmful goods.
The Customs Act, 1962 is the procedural and machinery law. It came into force on 1 February 1963, on the date the Central Government appointed by notification under section 1(3). It replaced older laws such as the Sea Customs Act, 1878 and the Land Customs Act, 1924, and the Indian Tariff Act, 1934 was amended. Section 160 deals with repeal and savings: actions taken under a repealed enactment are deemed to be taken under the corresponding provision of this Act, so long as they are not inconsistent with it.
Extent (section 1(2)): the Act extends to the whole of India. Since the 2018 amendment, it also applies, save as otherwise provided, to any offence or contravention under it committed outside India by any person.
The charging provision is section 12. Except as otherwise provided in the Act or any other law, duties of customs are levied at the rates specified under the Customs Tariff Act, 1975 or any other law, on goods imported into or exported from India. Section 12(2) says this applies equally to goods belonging to the Government.
The Customs Tariff Act, 1975 holds the rates. Its First Schedule covers import duties and its Second Schedule covers export duties. It also contains provisions on anti-dumping, countervailing and safeguard duties. The constitutional source of the power to levy customs duty is the Union List of the Constitution: Parliament has the power to legislate on duties of customs including export duties. Learn this as Entry 83 of the Union List.
The main types of duty you should know are: basic customs duty, integrated tax (IGST) on imports, social welfare surcharge, anti-dumping duty, countervailing duty, safeguard duty and export duty. Under section 28H, an applicant can seek an advance ruling on questions such as classification, applicability of notifications, valuation principles and origin of goods.

Common mistakes in Introduction to the Customs Act, 1962
Saying the Customs Act, 1962 contains the rates of duty.
Students merge the two Acts because both deal with customs.
Fix: Say the Customs Act is the machinery law and the rates are in the Customs Tariff Act, 1975, as section 12 itself points out.
Writing that the Act applies only within India's territory.
Students recall only the first half of section 1(2).
Fix: Add that it also applies, save as otherwise provided, to offences or contraventions committed outside India by any person.
Treating the Act as effective from the date it was passed.
Students assume all Acts start on assent.
Fix: State that section 1(3) lets the Central Government appoint the date by notification, and the date was 1 February 1963.
Claiming that Government-owned goods are exempt from duty.
Students assume the State does not tax itself.
Fix: Cite section 12(2): the levy applies to Government goods just as to other goods.
Listing only basic customs duty as the type of duty.
Students stop at the best-known duty.
Fix: List basic duty, IGST on imports, social welfare surcharge, anti-dumping, countervailing, safeguard and export duty.

Worked examples
Example 1
Explain the extent and commencement of the Customs Act, 1962. Does it apply to an offence committed abroad by a foreign national?
Show the solution
- Provision: section 1(2) says the Act extends to the whole of India.
- Section 1(2) also says that, save as otherwise provided, it applies to any offence or contravention under the Act committed outside India by any person.
- The words 'any person' are not limited to Indian citizens.
- Section 1(3): the Act comes into force on the date appointed by the Central Government by notification. The date appointed was 1 February 1963.
Answer: The Act extends to the whole of India and began on 1 February 1963. Because section 1(2) covers offences outside India by any person, it can apply to a foreign national's offence abroad, unless the Act provides otherwise.
Example 2
State the charging provision of customs duty. Is a Government department importing machinery liable to duty? Which Act contains the rates?
Show the solution
- Provision: section 12(1) levies customs duty on goods imported into, or exported from, India, at rates specified under the Customs Tariff Act, 1975 or any other law.
- Section 12(2) states that the levy applies to goods belonging to Government as it applies to other goods.
