Explanation
Why Correct: Customs duties are indirect taxes levied on goods imported into and exported out of a country. In India, the Customs Act, 1962 and the Customs Tariff Act, 1975 govern these levies, which include basic customs duty, countervailing duty, and anti-dumping duty.
Distractor Analysis: Excise duties are taxes on goods manufactured or produced within the country, not on cross-border trade. VAT (Value Added Tax) is a multi-stage consumption tax on the value added at each stage of production and distribution, levied on domestic sales. GST (Goods and Services Tax) is a comprehensive indirect tax on the supply of goods and services within India, subsuming many indirect taxes but not customs duties.
Takeaway: Customs duties are levied on both imports and exports, but in India export duties are rarely imposed; the primary revenue comes from import duties. The GST regime did not subsume customs duties, which remain a separate source of central government revenue.
