The House Small Business Subcommittee on Exports, Tax Policy and Special Problems and Small Business Subcommittee on Environment and Labor hold hearings examining federal efforts to promote the user of electronic data interchange (EDI). Members of Congress note that the proliferation of EDI is vital to US industrial competitiveness because it allows the exchange of routine business transactions without using paper. More than half of Fortune 1000 firms are currently installing or using EDI, and another 24 percent are considering it. EDI is a major part of the Customs Service's Automated Broker Interface system, which lets companies file customs entry declarations electronically. The Defense Department is also helping small businesses break into EDI because 70 percent of its 15 million contracts involve small firms. DOD is implementing an electronic commerce system under which all firms dealing with the department can exchange paperwork electronically.
