(a) One hundred percent screening of cargo containers and 100 percent scanning of high-risk containers

(1) Screening 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.

(2) Scanning of high-risk containers
The Secretary shall ensure that 100 percent of the containers that have been identified as high-risk under paragraph (1), or through other means, are scanned or searched before such containers leave a United States seaport facility.

(b) Full-scale implementation

(1) In general
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.

(2) Application
Paragraph (1) shall apply with respect to containers loaded on a vessel in a foreign country on or after the earlier of—

(A) July 1, 2012; or

(B) such other date as may be established by the Secretary under paragraph (3).

(3) Establishment of earlier deadline
The Secretary shall establish a date under (2)(B) ¹ pursuant to the lessons learned through the pilot integrated scanning systems established under section 981 of this title.

(4) Extensions
The Secretary may extend the date specified in paragraph (2)(A) or (2)(B) for 2 years, and may renew the extension in additional 2-year increments, for containers loaded in a port or ports, if the Secretary certifies to Congress that at least two of the following conditions exist:

(A) Systems to scan containers in accordance with paragraph (1) are not available for purchase and installation.

(B) Systems to scan containers in accordance with paragraph (1) do not have a sufficiently low false alarm rate for use in the supply chain.

(C) Systems to scan containers in accordance with paragraph (1) cannot be purchased, deployed, or operated at ports overseas, including, if applicable, because a port does not have the physical characteristics to install such a system.

(D) Systems to scan containers in accordance with paragraph (1) cannot be integrated, as necessary, with existing systems.

(E) Use of systems that are available to scan containers in accordance with paragraph (1) will significantly impact trade capacity and the flow of cargo.

(F) Systems to scan containers in accordance with paragraph (1) do not adequately provide an automated notification of questionable or high-risk cargo as a trigger for further inspection by appropriately trained personnel.

(5) Exemption for military cargo
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.

(6) Report on extensions
An extension under paragraph (4) for a port or ports shall take effect upon the expiration of the 60-day period beginning on the date the Secretary provides a report to Congress that—

(A) states what container traffic will be affected by the extension;

(B) provides supporting evidence to support the Secretary's certification of the basis for the extension; and

(C) explains what measures the Secretary is taking to ensure that scanning can be implemented as early as possible at the port or ports that are the subject of the report.

(7) Report on renewal of extension
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.

(8) Scanning technology standards
In implementing paragraph (1), the Secretary shall—

(A) establish technological and operational standards for systems to scan containers;

(B) ensure that the standards are consistent with the global nuclear detection architecture developed under the Homeland Security Act of 2002 [6 U.S.C. 101 et seq.]; and

(C) coordinate with other Federal agencies that administer scanning or detection programs at foreign ports.

(9) International trade and other obligations
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.

(c) Report
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.
