Customs-Trade Partnership Against Terrorism (C-TPAT) is a joint initiative between customs importers, terminal operators, carriers and others in the supply chain to make a self-assessment of their security.

This initiative adjusts security standards where necessary and communicates these new practices to ensure tighter security to our vendors and other entities in the supply chain.

Origin Container Security
CFS Operator will ensure that no unauthorized persons or materials are allowed near containers at the origin CFS.  This includes ensuring the containers are stored in a secure area to prevent unauthorized access and/or manipulation. CFS Operator will have in place procedures for reporting and neutralizing unauthorized entry into containers or container storage areas.
The physical integrity of container structures will be checked prior to stuffing.  This includes the reliability of the locking mechanisms of the doors, as well as inspecting for holes/damage the front wall, left side, right side, floor, ceiling/roof, inside/outside doors, and outside/ undercarriage.  All containers that are not physically sound should be rejected with a written message sent to the provider of the container requesting a replacement. 
Ocean shipping containers will be properly sealed immediately upon completion of loading in order to maintain the integrity of the cargo within the container.  A high security seal will be affixed to all loaded containers bound for the U.S.  All seals must meet or exceed the current PAS ISO 17712 standards for high security seals.
All container seal numbers should be noted on the Bill of Lading, as well as recorded in a log that links the seal number to the container number, the consignee, the shipping date, the vessel/voyage, the carrier, the staff member affixing the seal, and the date the container left the facility.  The log should also note any seal issues such as compromised seals or seals not affixed correctly.  The log should be kept in a secure location for at least five years. 
Only designated employees should distribute container seals for integrity purposes
The flexible enforcement period on 10+2 ISF filing has ended and CBP may begin issuing penalties at any time without further notice. The ISF needs to be filed no later than 24 hours prior vessel loading. CBP may issue liquidated damages of $5,000 per violation for the submission of an inaccurate, incomplete or untimely filing. If goods for which an ISF has not been filed arrive in the U.S., CBP may withhold the release or transfer of the cargo; CBP may refuse to grant a permit to unlade for the merchandise; and if such cargo is un-laden without permission, it may be subject to seizure. Additionally, noncompliant cargo could be subject to "do not load" orders at origin or further inspection on arrival.
