According to the final rule published in the Federal Register on December 23, 2020, The U.S. Department of Commerce put into effect a new system- Aluminum Import Monitoring and Analysis (AIM). Beginning on January 25, 2021, licenses will now be required in order to import all Aluminum covered products.
This new system will be similar to the Steel Import Monitoring and Analysis System (SIMA). Therefore, users who have an existing SIMA account can apply for their aluminum licenses there. If you already have a steel license, you may not add aluminum HTS codes. Instead, you must apply for a distinct aluminum license. The aluminum license form will become available on January 4, 2021.
