Industry, Commerce, Trade and Aids to Trade: ISC Class 11 Business Studies

Updated 17 October 2026 · Fact-checked

Business activities are classified as industry (primary, secondary and tertiary) and commerce (trade and aids to trade). Industry deals with the production of goods; commerce removes hindrances in the exchange of goods. Primary industry is extractive or genetic, secondary is manufacturing or construction, and tertiary is services. Trade is buying and selling; aids to trade are banking, insurance, transport, warehousing, communication and advertising.

Understand Classification of Business: Industry, Commerce, Trade and Aids to Trade

Industry. Activities connected with production or processing of goods.

*Primary industry:* extractive (mining, fishing, farming, forestry) and genetic (breeding plants and animals: nurseries, hatcheries, poultry).
*Secondary industry:* manufacturing (analytical, synthetic, processing, assembling) and construction (roads, dams, buildings).
*Tertiary industry:* services that support the others: banking, transport, insurance, telecommunication.

Commerce. All activities that remove hindrances of person (trade), place (transport), time (warehousing), knowledge (advertising, communication), finance (banking) and risk (insurance) in the movement of goods from producers to consumers. Commerce = Trade + Aids to trade.

Trade. Buying and selling of goods and services.

*Internal (home) trade:* within a country: wholesale and retail.
*External trade:* between countries: import, export and entrepot (re-export).

Aids to trade.

Aid	Hindrance removed
Transport	Place
Warehousing	Time
Banking	Finance
Insurance	Risk
Communication	Knowledge
Advertising	Knowledge of products

Business ethics and CSR (meaning). *Business ethics* are the moral principles guiding conduct (honesty, fair dealing, no adulteration). *Corporate social responsibility* means a business's obligation to act for the benefit of society and the environment as well as for profit.

Importance. Industries give goods and jobs; commerce delivers them to consumers; both depend on each other.
