New Aluminum Import Monitoring (AIM) Requirements

Plain-English explanation

CSMS 51720841 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on April 26, 2022. It carries the official CBP guidance brokers and importers must follow for the topic — "New Aluminum Import Monitoring (AIM) Requirements". 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 #51720841 - New Aluminum Import Monitoring (AIM) Requirements U.S. Customs and Border Protection sent this bulletin at 04/26/2022 03:39 PM EDT Cargo Systems Messaging Service CSMS #51720841 - New Aluminum Import Monitoring (AIM) Requirements Beginning June 29, 2022 , U.S. Commerce Department (Commerce) Aluminum Import licensing applications will require both fields of “country of largest smelt” and “country of second largest smelt.” Commerce defines the field for the country of smelt for the largest (and second largest) volume of primary aluminum as the country where the largest volume of new aluminum metal is produced from alumina (refined aluminum oxide) by the electrolytic Hall-Héroult process. Based on public comments in response to the preliminary rule, it was determined that importers/brokers would need time to gather required information for the countries of smelt and a grace period was granted for these fields; importers were permitted to indicate “unknown” for one year upon implementation of the regulations. Commerce extended the temporary period to allow for license applicants to state “unknown” in the fields for country(ies) of smelt for the largest and second largest volume of primary aluminum until June 28, 2022. Commerce will begin requiring the requested information for these fields for license applications on or after June 29, 2022, meaning that filers may no longer state “unknown” for these fields after that date.

Frequently asked questions

What is CSMS 51720841?

CSMS 51720841 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "New Aluminum Import Monitoring (AIM) Requirements". 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 51720841 published?

CBP published CSMS 51720841 on April 26, 2022. 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.
