From the Highlights: "CBP [U.S. Customs and Border Protection] monitors, regulates, and facilitates the movement of commodities through U.S. ports. The agency staffs 328 U.S. ports, where goods are imported and exported by truck, rail, plane, and ocean vessel. In fiscal year 2021, CBP processed 36.9 million import shipments and collected approximately $93.8 billion in duties, taxes, and other fees, including user fees for inspections at U.S. ports. The CARES [Coronavirus Aid, Relief, and Economic Security] Act includes a provision for GAO [Government Accountability Office] to conduct monitoring and oversight of the federal response to the pandemic. For this report, GAO (1) analyzed general trends in U.S. international trade since the pandemic's onset, (2) identified steps CBP took to respond to challenges stemming from the pandemic, and (3) determined the extent to which the pandemic has affected CBP's processing and release of import shipments and other operations at U.S. ports."
