CTPAT launches as a voluntary program (2001)
After the September 11 attacks, CBP created the Customs-Trade Partnership Against Terrorism, asking importers, carriers, and brokers to meet supply-chain security standards in exchange for faster clearance and fewer inspections. Participation was optional.
Thousands of companies joined to reduce border delays.
CTPAT became the main way CBP vets the companies it deals with, and validation turned into a marker of reliability.
The new rule converts a voluntary program into a requirement for any foreign company that wants to file its own entries.
