UPDATE Harmonized System Updates (HSU) 2103, 2104 and 2105

Plain-English explanation

CSMS 47863183 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on May 20, 2021. It carries the official CBP guidance brokers and importers must follow for the topic — "*UPDATE* Harmonized System Updates (HSU) 2103, 2104 and 2105". 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 #47863183 - *UPDATE* Harmonized System Updates (HSU) 2103, 2104 and 2105 U.S. Customs and Border Protection sent this bulletin at 05/20/2021 04:47 PM EDT Cargo Systems Messaging Service CSMS #47863183 - *UPDATE* Harmonized System Updates (HSU) 2103, 2104 and 2105 The purpose of this message is to clarify the HSU 2103 and 2104 updates and notify of the latest HSU 2105 update. Background : On Monday, March 29, 2021 HSU 2013 was created and included the Aluminum Import License (AIM) updates. Later that same day at the request of the Department of Commerce the AIM license updates were delayed until June 28, 2021 resulting in a new HSU update 2104. Due to HSU 2103 and 2104 being performed on the same day the changes were only captured in HSU 2103. There were no records updated in HSU 2104 so it will show all zeros and HSU 2103 was updated to exclude the AIM updates. The latest Harmonized System Update (HSU) 2105 was created on May 19, 2021 and contains 414 ABI records and 83 harmonized tariff records.

Frequently asked questions

What is CSMS 47863183?

CSMS 47863183 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "*UPDATE* Harmonized System Updates (HSU) 2103, 2104 and 2105". 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 47863183 published?

CBP published CSMS 47863183 on May 20, 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.
