The trade balance (balance of trade) is the difference between the value of a country's merchandise (goods) exports and imports over a period; a trade deficit occurs when goods imports exceed goods exports, and a trade surplus when exports exceed imports.
The goods-only scope of the trade balance, India's structural goods deficit (oil and gold), and the services surplus offset are core external-sector facts.
The trade balance (goods only) is narrower than the current account (goods plus services, income, transfers); India runs a goods trade deficit but a services trade surplus.
Goods exports minus goods imports; India runs a merchandise trade deficit, partly offset by a services surplus.
