Global trade, also known as international trade, involves the exchange of goods and services across international boundaries. It has existed for thousands of years, with early trade routes established by Assyrian merchants in the 19th century BC. Trade is important because it provides access to a variety of worldwide products, reduces risks from domestic economic and weather fluctuations, and increases quality through competition. Individuals and companies benefit from trade through market expansion, increased sales and profits, and reduced costs by importing cheaper raw materials. How trade works involves manufacturers producing goods that are exported, shipped internationally, and sold abroad to buyers in other countries. Jobs in international trade include roles in market research, regulations, consulting, shipping, customs, and international sales.
