U.S. EPA Import Requirements for Hydrofluorocarbons (HFCs) under the AIM Act

Plain-English explanation

CSMS 50274160 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on December 3, 2021. It carries the official CBP guidance brokers and importers must follow for the topic — "U.S. EPA Import Requirements for Hydrofluorocarbons (HFCs) under the AIM Act". CSMS messages are the operational layer between Commerce determinations and at-the-border collections: when Commerce publishes a new rate, scope ruling, or instruction, CBP turns it into a CSMS that ACE/ACS systems and brokers act on.

CSMS #50274160 - U.S. EPA Import Requirements for Hydrofluorocarbons (HFCs) under the AIM Act U.S. Customs and Border Protection sent this bulletin at 12/03/2021 12:41 PM EST Cargo Systems Messaging Service CSMS #50274160 - U.S. EPA Import Requirements for Hydrofluorocarbons (HFCs) under the AIM Act The purpose of this message is to announce an upcoming webinar on December 9, 2021, to be held in conjunction with the Environmental Protection Agency (EPA). This webinar will provide information about importing hydrofluorocarbons (HFCs), including upcoming filing requirements in ACE. The American Innovation and Manufacturing (AIM) Act directs EPA to phase down production and consumption of HFCs in the United States by 85 percent by 2036. HFCs are potent greenhouse gases, many of which have global warming potentials hundreds to thousands of times that of carbon dioxide. HFCs are commonly used in many sectors of the economy, including in refrigeration and air conditioning, aerosols, solvents, fire suppression, and as foam blowing agents. Consistent with the phasedown, starting January 1, 2022, there are new requirements for imports of HFCs. More specifically, imports of bulk HFCs and HFC blends of any quantity require allowances, subject to limited exceptions. In addition, EPA is requiring information to be electronically filed through ACE 14 days prior to importation. More information about the AIM Act and EPA’s regulations can be found at: https://www.epa.gov/climate-hfcs-reduction . In addition, a fact sheet for importers can be found here: https://www.epa.gov/system/files/documents/2021-11/hfc-allocation-rule-importer-requirements-fact-sheet.pdf .

Frequently asked questions

What is CSMS 50274160?

CSMS 50274160 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "U.S. EPA Import Requirements for Hydrofluorocarbons (HFCs) under the AIM Act". CSMS bulletins are the operational instructions CBP issues to brokers, importers, and ACE filers covering rate changes, system updates, scope guidance, and other day-to-day customs-operations changes.

When was CSMS 50274160 published?

CBP published CSMS 50274160 on December 3, 2021. The bulletin's instructions are typically operative as of the publication date unless the body specifies a different effective date.

Is the CBP CSMS the legally binding instruction?

Yes — for at-the-border filing and entry collection. CSMS messages translate Commerce's Federal Register determinations into operational CBP instructions that ACE/ACS systems and brokers execute. The Federal Register notice is the underlying legal authority; the CSMS is the operational implementation. Both should be read together when reconciling a rate or scope change.
