On November 14, 2023, U.S. Customs and Border Protection (CBP) published an updated tip sheet on new filing obligations for importing bulk hydrofluorocarbons (HFCs) under the American Innovation and Manufacturing (AIM) Act.

This tip sheet provides an overview of HFC regulatory requirements, a current list of Harmonized Tariff Schedule (HTS) codes for HFCs, instructions on how to file in Automated Commercial Environment (ACE) and examples of documents to upload in the Document Image System (DIS).

CBP confirmed in a companion Cargo Systems Messaging Service (CSMS) message that HFC ACE filing requirements are expected to be in production in early January 2024.
