The Schedule B, Harmonized Tariff Schedule (HTS), and HTS Codes That Are Not Valid for AES tables have been updated in the Automated Export System (AES) and the system will now accept the codes.
AES will continue to accept shipments with outdated codes for a grace period of 30 days beyond the expiration date of December 31, 2019. If you use an outdated code past the 30 days period you will receive a fatal error.
The ACE AESDirect program has also been updated with the 2020 codes and continue to accept shipments with outdated codes during the grace period.
Note: Effective January 1st, 2020, “X – No Unit Required” is no longer an acceptable Unit of Measure in AES for most commodity classification codes. There will be no grace period for this change.
