From the U. S. Census Bureau:
Effective immediately, the Harmonized Tariff Schedule (HTS), and HTS Codes That Are Not Valid for AES tables have been updated to accept the changes to the July 1, 2018 codes.
AES will accept shipments with outdated codes during a grace period for 30 days beyond the expiration date of June 30th, 2018. Reporting an outdated code after the 30-day grace period will result in a fatal error.
The ACE AESDirect program has been updated with the 2018 codes and will accept shipments with outdated codes during the grace period as well.
The 2018 Schedule B and HTS tables are available for downloading at:
