Affirmative final scope ruling - antidumping and countervailing duty orders on ammonium sulfate from the People's Republic of China (A-570-049)

Plain-English explanation

CSMS 3080403 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (trade policy), published on March 21, 2023. It carries the official CBP guidance brokers and importers must follow for the topic — "Affirmative final scope ruling - antidumping and countervailing duty orders on ammonium sulfate from the People's Republic of China (A-570-049)". It links to 1 AD/CVD case 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 03/16/2023, Commerce issued a final scope ruling that enriched 15N ammonium sulfate isotope imported by Cambridge Isotope Laboratories, Inc. is covered by the scope of the antidumping and countervailing duty orders on ammonium sulfate from the People's Republic of China (A-570-049). 2. Specifically, Commerce determined that enriched 15N ammonium sulfate isotope imported by Cambridge Isotope Laboratories, Inc. is covered by the scope of the orders because product is still ammonium sulfate based on the plan language in the scope of the orders. 3. This final scope ruling is applicable only to merchandise imported by Cambridge Isotope Laboratories, Inc. 4a. Continue to suspend liquidation of entries of enriched 15N ammonium sulfate isotope imported by Cambridge Isotope Laboratories, Inc. already subject to the suspension of liquidation under the antidumping and countervailing duty orders on ammonium sulfate from the People's Republic of China at the cash deposit rate(s) in effect on the date of entry in accordance with message 3011401, dated 01/11/2023. 4b. For all entries of enriched 15N ammonium sulfate isotope imported by Cambridge Isotope Laboratories, Inc. not already subject to the suspension of liquidation, CBP should suspend liquidation of: (i) shipments entered, or withdrawn from warehouse, for consumption on or after 12/14/2022, and (ii) shipments entered, or withdrawn from warehouse, for consumption prior to the date of initiation of the scope inquiry but no earlier than November 4, 2021. CBP shall require, for such entries, a cash deposit at the applicable rate(s) in effect on the date of entry. 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: EK.) 8. There are no restrictions on the release of this information.

Frequently asked questions

What is CSMS 3080403?

CSMS 3080403 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "Affirmative final scope ruling - antidumping and countervailing duty orders on ammonium sulfate from the People's Republic of China (A-570-049)". 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 3080403 published?

CBP published CSMS 3080403 on March 21, 2023. 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 3080403 affect?

CSMS 3080403 references 1 AD/CVD case (A-570-049). 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.
