Affirmative final scope ruling - antidumping duty order on xanthan gum from the People's Republic of China (A-570-985) (Third Country Case Number A-122-985).

Plain-English explanation

CSMS 5155406 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (trade policy), published on June 4, 2025. It carries the official CBP guidance brokers and importers must follow for the topic — "Affirmative final scope ruling - antidumping duty order on xanthan gum from the People's Republic of China (A-570-985) (Third Country Case Number A-122-985).". It links to 2 AD/CVD cases in Tandom's catalog. 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.

Message body

Full text as published by U.S. Customs and Border Protection

1. On 05/20/2025, Commerce issued a final scope ruling that GPI Purexan 80AN, GPI Purexan 200AN, and GPI Quickxan 70 are covered by the scope of the antidumping duty order on xanthan gum from the People's Republic of China (A-570-985). 2. Specifically, Commerce determined that GPI Purexan 80AN, GPI Purexan 200AN, and GPI Quickxan 70 are covered by the scope of the order because the xanthan gum inputs that are manufactured in China are not substantially transformed when used to produce GPI Purexan 80AN, GPI Purexan 200AN, and GPI Quickxan 70 and that GPI Purexan 80AN, GPI Purexan 200AN, and GPI Quickxan 70 are covered by the description in the plain language of the scope of the order within the meaning of 19 CFR 351.225(k)(1). 3. This final scope ruling is applicable only to merchandise produced and exported by Gum Products International, Inc. 4a. Continue to suspend liquidation of entries of GPI Purexan 80AN, GPI Purexan 200AN, and GPI Quickxan 70 already subject to the suspension of liquidation under the antidumping duty order on xanthan gum from the People's Republic of China at the cash deposit rate in effect on the date of entry in accordance with message 3304402, dated 10/31/2023 (initiation message), and messages 4261402 and 4262404, dated 09/17/2024 and 09/18/2024, respectively (affirmative preliminary scope ruling message). 4b. For all entries of GPI Purexan 80AN, GPI Purexan 200AN, and GPI Quickxan 70 not already subject to the suspension of liquidation, CBP should suspend liquidation of: (i) shipments entered, or withdrawn from warehouse, for consumption on or after 10/23/2023 (date of initiation of the scope inquiry), and (ii) shipments entered, or withdrawn from warehouse, for consumption on or after 11/04/2021. CBP shall require, for such entries, a cash deposit at the applicable rate(s) in effect on the date of entry. Commerce established a third-country case number to allow products completed in Canada to be properly reported as subject to the order on xanthan gum from the People's Republic of China (A-570-985) upon entry. Third Country: Canada Case Number: A-122-985 Exporter: Country-Wide Case Number: A-570-985-000 Cash Deposit Rate: 154.07% The third country AD/CVD case number(s) above have been assigned for CBP purposes. 5. Entries of products covered by paragraph 4 should not be liquidated until specific liquidation instructions are issued. 6. In accordance with 19 CFR 351.225(l)(5), this instruction does not affect or otherwise limit CBP's independent authority to take any additional action with respect to the suspension of liquidation or related measures. 7. If there are any questions by the importing public regarding this message, please contact the Call Center for the Office of AD/CVD Operations, Enforcement and Compliance, International Trade Administration, U.S. Department of Commerce, at (202) 482-0984. CBP ports should submit their inquiries through authorized CBP channels only. (This message was generated by OIV:RA.) 8. There are no restrictions on the release of this information. Alexander Amdur

Frequently asked questions

What is CSMS 5155406?

CSMS 5155406 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "Affirmative final scope ruling - antidumping duty order on xanthan gum from the People's Republic of China (A-570-985) (Third Country Case Number A-122-985).". 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 5155406 published?

CBP published CSMS 5155406 on June 4, 2025. The bulletin's instructions are typically operative as of the publication date unless the body specifies a different effective date.

Which AD/CVD cases does CSMS 5155406 affect?

CSMS 5155406 references 2 AD/CVD cases (A-122-985, A-570-985). The links on this page take you to each linked order with its current scope, rates, and history.

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.
