The United States imposes AD/CV duties to remedy unfair foreign trade practices, such as unfairly low prices or subsidies that cause injury to domestic industries. Importers that seek to avoid paying appropriate AD/CV duties may employ methods of evasion such as illegally transshipping an import through a third country to disguise its true country of origin or falsifying the value of an import to reduce the amount of duties owed, among others. AD/CV duty evasion can harm U.S. companies and reduces U.S. revenues. CBP, within the Department of Homeland Security, leads efforts to detect and deter AD/CV duty evasion.

The Senators aske the GAO to examine “(1) how CBP detects and deters AD/CV duty evasion, (2) factors that affect CBP’s efforts, and (3) the extent to which CBP tracks and reports on its efforts. To address these objectives, GAO reviewed CBP data and documents; met with government and private sector representatives in Washington, D.C.; and conducted fieldwork at three domestic ports.”
