Missing 2024 HTS Updates in Harmonized System Update 2315

Plain-English explanation

CSMS 58918402 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on January 3, 2024. It carries the official CBP guidance brokers and importers must follow for the topic — "Missing 2024 HTS Updates in Harmonized System Update 2315". 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.

CBP is aware that there are several 2024 Harmonized Tariff Schedule (HTS) updates missing in Harmonized System Update (HSU) 2315. We are actively working to get those updates added. Once completed, a new HSU will be published, and a new file generated and sent out. A CSMS will follow immediately after. We apologize for any inconvenience and appreciate your patience as we get the missing updates implemented as quickly as possible. HTS Questions or concerns with the Harmonized System Update should be directed to the HTS admin @ HTSadmin@cbp.dhs.gov

Frequently asked questions

What is CSMS 58918402?

CSMS 58918402 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "Missing 2024 HTS Updates in Harmonized System Update 2315". 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 58918402 published?

CBP published CSMS 58918402 on January 3, 2024. 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.
