District Export Councils (DEC) District Export Councils are organizations of business leaders from local communities, appointed by various U.S. Secretaries of Commerce, whose expertise in international business provides a source of professional advice for their region’s local firms. DECs are closely affiliated with the U.S. Commerce Department’s Export Assistance Centers and the U.S. and Foreign Commercial Service. There are over 60 DECs throughout the US supporting the U.S. Government’s export promotion efforts. DECs play a major role in the planning and coordination of export activities for their communities.
