When using traditional measurements, small business exports represent about one third of total U.S. export value. However, these measures fail to take into account the value small businesses add to exports sold by large businesses. Using a value-added measurement approach developed by the U.S. International Trade Commission (USITC), Contributions of Small Business Indirect Exports to U.S. International Trade estimates the contributions small businesses make through indirect exports. The report finds that, once intermediate inputs to finished goods are included in small businesses’ export numbers, their share of U.S. exports rises to about 40%.
