A commodity is typically a tangible good that is bought and sold on the basis of price rather than unique qualities. In business and trade the term usually denotes products that are sufficiently uniform to be interchangeable: buyers accept any unit that meets an established grade or specification and compete mainly on price.

Marxian and political-economy perspective
In Marxian political economy the category of commodity carries theoretical weight beyond mere interchangeability. A commodity is any item or service produced for exchange that embodies both a use-value (its practical purpose) and an exchange-value (its value in markets). Discussions in this tradition treat commodities as social forms that reflect labor, property relations and the ways value is measured and distributed; see Marxian analysis and related commentary in political economy.
Key characteristics
- Fungibility: individual units are substitutable when they meet standards.
- Standardization: quality grades, weights and contracts make trading efficient.
- Price-driven markets: supply and demand determine prices; branding has limited influence.
- Classification: often divided into "hard" commodities (metals, energy) and "soft" commodities (agriculture).
Common examples include crude oil, wheat, copper and gold. Some items become commodities after processing when differences between producers are small; others remain differentiated through branding or specialized features.
Markets, uses and importance
Commodities are traded on spot markets and derivatives exchanges, where futures, options and swaps enable producers, consumers and investors to hedge price risk or speculate. Commodity markets perform price discovery for raw materials that feed manufacturing, food supply chains and energy systems. Because many national economies rely on commodity exports, prices influence trade balances, investment and development trajectories.
Distinguishing commodities from differentiated goods helps explain business strategies: firms try to avoid pure commoditization by adding services, quality labels or brand recognition, while traders and financial actors focus on liquidity and standard contracts. Understanding commodities is therefore important for commerce, policy and debates about labor, value and the environment.
