AES Trade Interface Requirements (AESTIR)
The CBP Automated Export System Trade Interface Requirements (AESTIR) provide the Customs Proprietary and ANSI X.12 record formats for transmitting commodity and transportation export data to CBP via AES. The Appendices to the AESTIR provide reference files used by AES to validate certain required data elements.
The General Information section of the AESTIR provides an introduction to the system as well as information on becoming a participant in AES.
Users should check here monthly for any changes to the documentation. For further information or questions, contact the U.S. Census Bureau's AES Branch. Telephone: (800) 549-0595, select option 1 for AES from 7:30 a.m. - 5:30 p.m. Eastern time. Email: email@example.com
