AES Update for New BIS License Types

C65 – Temporary General License and C66 – Supply Chain Authorization Letter


The Automated Export System has been modified to report shipments governed by last Fall's Certain Advanced Computing and Semiconductor Manufacturing Items; Supercomputer and Semiconductor End Use Rules.

Following October’s Authorized Cybersecurity Exports action the Department of Commerce has established a Temporary General License to avoid disruption of supply chains for certain items that are ultimately destined to customers outside of People’s Republic of China (China) or Macau. 

In a separate series of actions, the BIS Deputy Assistant Secretary for Export Administration issued a number of Supply Chain Authorization Letters which describe specific authorizations granted pursuant to requests based on exigent circumstances of actual or potential supply chain disruptions. 

As a result of these actions, changes will be made to the Automated Export System (AES) in order for exporters and authorized agents to successfully report electronic export information in the AES.

A complete list of all of the AES License Codes and reporting instructions for these types can be found at:  AESTIR Appendix F - License and License Exemption Type Codes | U.S. Customs and Border Protection (
