In economics, a commodity is a non-monetary good, normally a physical commodity , which has a complete or substantial fungability: that is, that the marketplace treats cases of this good as basically equivalent or near so to no difference whatever to that which was produced by another producer. Commodities are goods produced from raw materials in such quantities and at such trade prices that their sale is the most direct method of receiving money from their producers. More precisely, goods which can be directly traded between producers are called commodities, while goods that can only be transferred by traders are called raw materials.
