S. 1822 would require U.S. Customs and Border Protection (CBP) to increase its use of nonintrusive inspection (NII) systems at land ports of entry. By the end of fiscal year 2026, the bill would require CBP to use NII systems to inspect 40 percent of passenger vehicles and 90 percent of commercial vehicles entering the United States. NII systems, such as large-scale X-ray and Gamma-ray systems and handheld scanners, are used to quickly examine vehicles for weapons, narcotics, and other materials that pose nuclear and radiological threats.
