6 U.S. Code § 982 - Screening and scanning of cargo containers
The Secretary shall ensure that 100 percent of the cargo containers originating outside the United States and unloaded at a United States seaport undergo a screening to identify high-risk containers.
A container that was loaded on a vessel in a foreign port shall not enter the United States (either directly or via a foreign port) unless the container was scanned by nonintrusive imaging equipment and radiation detection equipment at a foreign port before it was loaded on a vessel.
Notwithstanding any other provision in the section, supplies bought by the Secretary of Defense and transported in compliance section 2631 of title 10 and military cargo of foreign countries are exempt from the requirements of this section.
If an extension under paragraph (4) takes effect, the Secretary shall, after one year, submit a report to Congress on whether the Secretary expects to seek to renew the extension.
In carrying out this subsection, the Secretary shall consult with appropriate Federal departments and agencies and private sector stakeholders, and ensure that actions under this section do not violate international trade obligations, and are consistent with the World Customs Organization framework, or other international obligations of the United States.
Not later than 6 months after the submission of a report under section 981(d) of this title, and every 6 months thereafter, the Secretary shall submit a report to the appropriate congressional committees describing the status of full-scale deployment under subsection (b) and the cost of deploying the system at each foreign port at which the integrated scanning systems are deployed.
 So in original. Probably should be “paragraph (2)(B)”.
The Homeland Security Act of 2002, referred to in subsec. (b)(8)(B), is Pub. L. 107–296, Nov. 25, 2002, 116 Stat. 2135, which is classified principally to chapter 1 (§ 101 et seq.) of this title. For complete classification of this Act to the Code, see Short Title note set out under section 101 of this title and Tables.
2007—Subsec. (b). Pub. L. 110–53 reenacted heading without change and amended text of subsec. (b) generally. Prior to amendment, text related to full deployment of an integrated scanning system after the Secretary had determined that such system had met section 981(c) requirements, had a sufficiently low false alarm rate, was capable of being deployed overseas, was capable of integrating with existing systems, would not significantly impact trade flow, and had provided for automated notification of high-risk cargo.
