Customs rules can be complex in the U.S. and the regulatory environment is continually evolving. This is especially true in the area of security compliance where both importers and exporters can face significant penalties for non-compliance with the latest requirements. In addition to the CBP, several other U.S. federal government agencies are involved in regulating, or have oversight over aspects of, U.S. imports and exports. These include the Bureau of Industry and Security, the Food and Drug Administration, the Department of the Interior and the Department of Agriculture. Various duty savings opportunities may be leveraged in the U.S. from an in-depth understanding of local customs rules and practices.
