The Customs Modernization Act (Mod Act) of 1993 amended many sections of the Tariff Act of 1930. Among those changes were the concepts of Shared Responsibility and Reasonable Care. Shared Responsibility puts the responsibility on U.S. Customs to provide the trade community with clear and complete information regarding its rights and legal obligations related to importing merchandise. This concept also puts the responsibility on the trade community to access and understand that information and to use Reasonable Care in all declarations to U.S. Customs.
