Electronic Export Information (EEI) - AESTIR Appendix A “ Commodity Filing Response Messages Update for New Automated Export System (AES) Informational Message

Plain-English explanation

CSMS 54455271 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on December 22, 2022. It carries the official CBP guidance brokers and importers must follow for the topic — "Electronic Export Information (EEI) - AESTIR Appendix A “ Commodity Filing Response Messages Update for New Automated Export System (AES) Informational Message". 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 # 54455271 - Electronic Export Information (EEI) - AESTIR Appendix A – Commodity Filing Response Messages Update for New Automated Export System (AES) Informational Message U.S. Customs and Border Protection sent this bulletin at 12/22/2022 01:44 PM EST   Cargo Systems Messaging Service CSMS # 54455271 - Electronic Export Information (EEI) - AESTIR Appendix A – Commodity Filing Response Messages Update for New Automated Export System (AES) Informational Message The AESTIR Appendix A – Commodity Filing Response Messages has been posted on cbp.gov with an update of adding this Informational Response Message: https://www.cbp.gov/document/guidance/aestir-appendix-commodity-filing-response-messages?utm_campaign=&utm_content=&utm_medium=email&utm_source=govdelivery This message is a follow-up to a CENSUS broadcast that was released on June 30, 2022, titled Guidance on Filing the USPPI Address and State of Origin in the Automated Export System .  This is intended to provide clear guidance for U.S. Principal Parties in Interest (USPPI) when the USPPI Address State and State of Origin do not match on the Electronic Export Information (EEI) in the Automated Export System (AES).  If the U.S. State codes do not match, filers shall begin filing in compliance with the Foreign Trade Regulations (FTR) going forward. To ensure further compliance with the FTR, specifically ensuring the USPPI Address in section 30.6(a)(1)(ii) and the State of Origin in section 30.6(a)(4) match, the Census Bureau will be deploying a new Informational Message in the AES.  The message will be active in the Certification testing environment on January 10, 2023 and will go into the Production environment on February 7, 2023.  This Informational Message will allow the filer to take notice of the USPPI Address and State of Origin fields being reported on the EEI in the AES when the data elements do not match and make changes. Exporters and Software Developers that submit Electronic Export Information (EEI) via the Electronic Data Interface (EDI) will need to program and test their software so that their clients receive the new response code message outlined below. Response Code: 26C Narrative Text: STATE OF ORIGIN / USPPI STATE MISMATCH Severity: INFORMATIONAL Proprietary Record/Data Elements: Input SC1 Record/U.S. State of Origin; Input N03 Record/USPPI State Code X.12 Segment ID/Data Elements:  BA108, and the USPPI State Code is N402 Reason: The U.S. State of Origin Code and USPPI Address State Code do not match. Resolution:   The State of Origin and USPPI State must match and be reported as the location from which the goods actually begin the journey to the port of export as defined in section 30.6(a)(1)(ii) and 30.6(a)(4) of the Foreign Trade Regulations. Any reporting errors must be corrected and retransmitted.  For further assistance, contact the Census Bureau’s Trade Regulations Branch at 1-800-549-0595, (Option 3).  If additional clarification is needed on this topic or any other regulatory matters, please contact the Census Bureau’s Trade Regulations Branch at (800) 549-0595, Option 3, or by email at emd.askregs@census.gov For general questions regarding AES, contact the U.S. Census Bureau's Trade Data Collection Branch at 1-800-549-0595 (option 1) or askaes@census.gov .

Frequently asked questions

What is CSMS 54455271?

CSMS 54455271 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "Electronic Export Information (EEI) - AESTIR Appendix A “ Commodity Filing Response Messages Update for New Automated Export System (AES) Informational Message". 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 54455271 published?

CBP published CSMS 54455271 on December 22, 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.
