When coffee is traded between countries it is called a

Coffee is a popular beverage and an important commodity. Tens of millions of small producers in developing countries make their living growing coffee. Over 2.25 billion cups of coffee are consumed in the world daily. Over 90 percent of coffee production takes place in developing countries—mainly South America—while consumption happens primarily in industrialized economies. There are 25 million small producers who rely on coffee for a living worldwide. In Brazil, where almost a third of the world's coffee is produced, over five million people are employed in the cultivation and harvesting of over three billion coffee plants; it is a more labour-intensive culture than alternative cultures of the same regions, such as sugar cane or cattle, as its cultivation is not automated, requiring frequent human attention.

Coffee is a major export commodity and was the top agricultural export for 12 countries in 2004; the world's seventh-largest legal agricultural export, by value, in 2005; and "the second most valuable commodity exported by developing countries," from 1970 to circa 2000,[1][2] which is frequently misstated—see coffee commodity market.[3][4] Unroasted, or green, coffee beans comprise one of the most traded agricultural commodities in the world;[5] the commodity is traded in futures contracts on many exchanges, including the New York Board of Trade, New York Mercantile Exchange, New York Intercontinental Exchange, and the London International Financial Futures and Options Exchange. Important trading and processing centers for coffee in Europe are Hamburg and Trieste.
