In the context of the supply chain, a commodity refers to a raw material, product, or goods that are traded in large quantities. It can be categorized as a basic, interchangeable, and widely available product that does not have significant differentiation between brands or sources. Common examples of commodities include agricultural products (such as wheat, corn, and coffee), metals (such as gold, silver, and copper), energy resources (such as oil and natural gas), and other goods that are traded on commodity exchanges.
