name: Customs and Border Protection
kind: government
description: U.S. Customs and Border Protection (CBP) is the federal law enforcement agency within the Department of Homeland
  Security responsible for apprehending individuals attempting to enter the United States illegally, stemming the flow of
  illegal drugs and contraband, protecting agricultural and economic interests from harmful pests and diseases, protecting
  intellectual property, and regulating and facilitating international trade, collecting import duties, and enforcing U.S.
  trade laws. CBP's primary trade automation systems are the Automated Commercial Environment (ACE), the Automated Export
  System (AES), AESDirect, the Advance Passenger Information System (APIS / eAPIS), and the Air Cargo Advance Screening (ACAS)
  program. Trade integrations are predominantly delivered through Electronic Data Interchange (EDI) messaging via ACE, with
  a small set of CBP web services (e.g., the AESDirect WebLink Inquiry API) exposed for programmatic use.

  description: The Advance Passenger Information System (APIS) collects pre-arrival and pre-departure manifest data on all
    passengers and crew members flown or sailed into and out of the United States. The eAPIS web portal allows commercial
    operators and private aircraft and vessel operators to create, manage, and submit APIS manifests. Bulk and partner integrations
    use UN/EDIFACT PAXLST and CUSRES messages over CBP-approved transmission methods.

  description: ACE is the U.S. Single Window through which the trade community reports imports and exports and CBP and Partner
    Government Agencies determine admissibility. Trade users access ACE via the ACE Secure Data Portal (a free web-based interface)
    and via ACE Electronic Data Interchange (EDI), which uses CBP-approved CAMIR/AESTIR messaging standards. The ACE Portal
    modernization program completed user access management migration in February 2025.
