It is the exchange where commodities are traded. Several raw materials are traded on the commodity exchange through standardized contracts. These contracts are traded physically (direct exchange) or through the exchange on the derivatives market. Commodities are classified into three categories: softs (coffee, sugar, tea, cocoa, spices, gum, cotton, wool, rice, oats, timber, meat, livestock, corn), metals (gold, silver, platinum, rhodium, ruthenium, tin, pounce, zinc, aluminium, and nickel), energy sector (gas, oil, and their derivatives). Other commodities are precious metals, as old coins, construction materials, IPOs and software. 
These materials are exchanged over the commodity exchanged through standardized contracts. These exchanges take place physically (direct exchange) or through an exchange over the derivatives market.
