Antidumping duty order on calcium hypochlorite from the People's Republic of China (A-570-008)

Plain-English explanation

CSMS 5043301 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (trade policy), published on February 12, 2015. It carries the official CBP guidance brokers and importers must follow for the topic — "Antidumping duty order on calcium hypochlorite from the People's Republic of China (A-570-008)". 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 1/30/2015, Commerce published in the Federal Register its antidumping duty order on calcium hypochlorite from the People's Republic of China (80 FR 5085). 2. The merchandise covered by this order is calcium hypochlorite, regardless of form (e.g., powder, tablet (compressed), crystalline (granular), or in liquid solution), whether or not blended with other materials, containing at least 10 percent available chlorine measured by actual weight. The scope also includes bleaching powder and hemibasic calcium hypochlorite. Calcium hypochlorite has the general chemical formulation Ca(OCl)2, but may also be sold in a more dilute form as bleaching powder with the chemical formulation, Ca(OCl)2.CaCl2.Ca(OH)2.2H2O or hemibasic calcium hypochlorite with the chemical formula of 2Ca(OCl)2.Ca(OH)2 or Ca(OCl)2.0.5Ca(OH)2. Calcium hypochlorite has a Chemical Abstract Service (“CAS”) registry number of 7778-54-3, and a U.S. Environmental Protection Agency (“EPA) Pesticide Code (“PC”) Number of 014701. The subject calcium hypochlorite has an International Maritime Dangerous Goods (“IMDG”) code of Class 5.1 UN 1748, 2880, or 2208 or Class 5.1/8 UN 3485, 3486, or 3487. Calcium hypochlorite is currently classifiable under the subheading 2828.10.0000 of the Harmonized Tariff Schedule of the United States (“HTSUS”). The subheading covers commercial calcium hypochlorite and other calcium hypochlorite. When tableted or blended with other materials, calcium hypochlorite may be entered under other tariff classifications, such as 3808.94.5000 and 3808.99.9500, which cover disinfectants and similar products. While the HTSUS subheadings, the CAS registry number, the U.S. EPA PC number, and the IMDG codes are provided for convenience and customs purposes, the written description of the scope of this order is dispositive. 3. For imports of calcium hypochlorite from the People's Republic of China, CBP shall suspend liquidation of entries of subject merchandise entered, or withdrawn from warehouse, for consumption on or after 1/27/2015 (date of publication of the International Trade Commission final determination in the Federal Register). Effective 1/27/2015, CBP shall require a cash deposit equal to the percentages for the exporter/producer combinations identified below. These cash deposit rates have been adjusted to reflect the appropriate subsidy offsets determined in the companion countervailing duty proceeding. Exporter: PRC-Wide Entity Case Number: A-570-008-000 Cash Deposit Rate: 200.9 percent 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, 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 OV:KM) 5. There are no restrictions on the release of this information. Michael B. Walsh

Frequently asked questions

What is CSMS 5043301?

CSMS 5043301 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "Antidumping duty order on calcium hypochlorite from the People's Republic of China (A-570-008)". 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 5043301 published?

CBP published CSMS 5043301 on February 12, 2015. 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 5043301 affect?

CSMS 5043301 references 1 AD/CVD case (A-570-008). 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.
