C-TPAT (Customs-Trade Partnership Against Terrorism)
This U.S. Customs Service (USCS) program works in conjunction with Mexico's PIP program to provide maximum border security while still permitting the free flow of low-risk, recognized trade. C-TPAT is a prerequisite for FAST (Free and Secure Trade) certification.

FAST (Free and Secure Trade) is a joint Mexico / U.S. program to ensure tightened border security along with the efficient movement of low-risk, known and legitimate commerce.

ACE (Automated Commercial Environment)
