Changes to Stow Plan Processing

Plain-English explanation

CSMS 50379140 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on December 13, 2021. It carries the official CBP guidance brokers and importers must follow for the topic — "Changes to Stow Plan Processing". 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 #50379140 - Changes to Stow Plan Processing U.S. Customs and Border Protection sent this bulletin at 12/13/2021 03:57 PM EST Cargo Systems Messaging Service CSMS #50379140 - Changes to Stow Plan Processing CBP plans to deploy to the Production environment several changes to Stow Plan processing on 1/13/2022. Three changes in particular will have trade implications. First, users will no longer receive status notification (RC/350) messages when a Stow Plan is rejected by CBP. Stowplan filers need to ensure they receive and resolve all rejected Stow Plan messages, or they could be subject to penalty for failure to properly file a Stow Plan. The second trade facing impact will be to address vessels that do not have an IMO number. Stow Plan filers will now be able to transmit data to CBP where a vessel is transporting containers and the vessel does not have an IMO. The formatting for those vessels without a Stow Plan will be to enter "NOIMO" in the IMO field followed by the first 2-4 letters of the vessel type. These vessel types shown below are valid: Syntax - " NOIMO[first 4 letters of vessel type] " Example: Vessel Type Accepted Code Barge NOIMOBA, NOIMOBAR, NOIMOBARG Support Vessel NOIMOSU, NOIMOSUP, NOIMOSUPP Other vessel types without an IMO are supported using the same syntax The third trade facing impact will be to record updates and deletes to original Stow Plan submissions. In the BGM segment, if CBP receives duplicate Stow Plans with the same message ID (BGM 02 element) and the same action code, the second submission will be issued an accepted with warnings (S03) response message (CUSRES). Additionally, if a voyage is no longer destined for the United States, a Stow Plan message can be submitted with the same message ID (BGM 02 element) and an action code of ‘3’, indicating a delete transaction. An example: Initial submission: BGM++11838+9' Second submission: BGM++11838+9' <- this submission will be issued an S03 - accepted with warnings. If an update or change needs to be made, the filer should use action code 4 or 5 Deleted example: Initial submission: BGM++11838+9' Delete submission: BGM++11838+3' Update your subscriptions, modify your password or e-mail address, or stop subscriptions at any time on your Subscriber Preferences Page .

Frequently asked questions

What is CSMS 50379140?

CSMS 50379140 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "Changes to Stow Plan Processing". 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 50379140 published?

CBP published CSMS 50379140 on December 13, 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.
