Initiation of countervailing duty investigation of certain frozen warmwater shrimp for Ecuador (C-331-803)

Plain-English explanation

CSMS 3028302 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (trade policy), published on January 28, 2013. It carries the official CBP guidance brokers and importers must follow for the topic — "Initiation of countervailing duty investigation of certain frozen warmwater shrimp for Ecuador (C-331-803)". 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.

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

1. On 01/25/2013, Commerce published in the Federal Register its initiation of the countervailing duty investigation of certain frozen warmwater shrimp from Ecuador (78 FR 5416). 2. The scope of this investigation is certain frozen warmwater shrimp and prawns, whether wild-caught (ocean harvested) or farm-raised (produced by aquaculture), head-on or head-off, shell-on or peeled, tail-on or tail-off (see footnote 1), deveined or not deveined, cooked or raw, or otherwise processed in frozen form, regardless of size. Footnote 1: “Tails” in this context means the tail fan, which includes the telson and the uropods. The frozen warmwater shrimp and prawn products included in the scope, regardless of definitions in the Harmonized Tariff Schedule of the United States (“HTSUS”), are products which are processed from warmwater shrimp and prawns through freezing and which are sold in any count size. The products described above may be processed from any species of warmwater shrimp and prawns. Warmwater shrimp and prawns are generally classified in, but are not limited to, the Penaeidae family. Some examples of the farmed and wild-caught warmwater species include, but are not limited to, whiteleg shrimp (Penaeus vannemei), banana prawn (Penaeus merguiensis), fleshy prawn (Penaeus chinensis), giant river prawn (Macrobrachium rosenbergii), giant tiger prawn (Penaeus monodon), redspotted shrimp (Penaeus brasiliensis), southern brown shrimp (Penaeus subtilis), southern pink shrimp (Penaeus notialis), southern rough shrimp (Trachypenaeus curvirostris), southern white shrimp (Penaeus schmitti), blue shrimp (Penaeus stylirostris), western white shrimp (Penaeus occidentalis), and Indian white prawn (Penaeus indicus). Frozen shrimp and prawns that are packed with marinade, spices or sauce are included in the scope. In addition, food preparations (including dusted shrimp), which are not “prepared meals,” that contain more than 20 percent by weight of shrimp or prawn are also included in the scope. Excluded from the scope are: (1) Breaded shrimp and prawns; (2) shrimp and prawns generally classified in the Pandalidae family and commonly referred to as coldwater shrimp, in any state of processing; (3) fresh shrimp and prawns whether shell-on or peeled; (4) shrimp and prawns in prepared meals; (5) dried shrimp and prawns; (6) canned warmwater shrimp and prawns; and (7) certain “battered shrimp” (see below). “Battered shrimp” is a shrimp-based product: (1) That is produced from fresh (or thawed-from-frozen) and peeled shrimp; (2) to which a “dusting” layer of rice or wheat flour of at least 95 percent purity has been applied; (3) with the entire surface of the shrimp flesh thoroughly and evenly coated with the flour; (4) with the non-shrimp content of the end product constituting between four and 10 percent of the product's total weight after being dusted, but prior to being frozen; and (5) that is subjected to individually quick frozen (“IQF”) freezing immediately after application of the dusting layer. When dusted in accordance with the definition of dusting above, the battered shrimp product is also coated with a wet viscous layer containing egg and/or milk, and par-fried. The products included in the scope of this investigation are currently classified under the following HTSUS subheadings: 0306.17.00.03, 0306.17.00.06, 0306.17.00.09, 0306.17.00.12, 0306.17.00.15, 0306.17.00.18, 0306.17.00.21, 0306.17.00.24, 0306.17.00.27, 0306.17.00.40, 1605.21.10.30 and 1605.29.10.10. These HTSUS subheadings are provided for convenience and for customs purposes only and are not dispositive, but rather the written description of the scope is dispositive. 3. This investigation has been assigned investigation number C-331-803. 4. If there are any questions by the importing public regarding this message, please contact the Call Center for the Office of AD/CVD Operations, Import Administration, 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 O1:AR.) 5. There are no restrictions on the release of this information. Michael B. Walsh

Frequently asked questions

What is CSMS 3028302?

CSMS 3028302 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "Initiation of countervailing duty investigation of certain frozen warmwater shrimp for Ecuador (C-331-803)". 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 3028302 published?

CBP published CSMS 3028302 on January 28, 2013. 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 3028302 affect?

CSMS 3028302 references 1 AD/CVD case (C-331-803). 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.
