U.S. Department of Commerce Releases Preliminary Results in Review of Chinese Chlorinated Isocyanurates
Estimated reading time: 3–5 minutes
The U.S. Department of Commerce, through its International Trade Administration, has released the preliminary results of its antidumping duty administrative review on chlorinated isocyanurates from the People’s Republic of China. This review covers shipments during the period June 1, 2023, through May 31, 2024.
Who Is Involved
The review covers two producers and exporters from China:
- Heze Huayi Chemical Co., Ltd.
- Juancheng Kangtai Chemical Co., Ltd.
These companies applied for “separate rate” status, which means they requested to be treated individually in the review instead of as part of the “China-wide entity.”
What Was Found
Commerce made preliminary findings that both Heze Huayi and Kangtai sold chlorinated isocyanurates in the U.S. for less than normal value, which is the basis for determining dumping. The following dumping margins were calculated:
- Heze Huayi Chemical Co., Ltd.: 18.39%
- Juancheng Kangtai Chemical Co., Ltd.: 4.77%
The China-wide rate remains 285.63% because no party requested a review of the China-wide entity.
How the Review Was Done
Commerce used data and methods based on U.S. law, using specific sections from the Tariff Act of 1930. China is considered a “non-market economy,” so special rules are used to calculate the normal value of products. The review looked at prices, sales, and other records provided by the companies.
Product Details
The products covered are called chlorinated isocyanurates. These chemicals are derivatives of cyanuric acid and are also known as chlorinated s-triazine triones. They are used for purposes like disinfectants and are identified under certain codes in the U.S. tariff schedule.
Next Steps and Public Comments
Interested parties can submit written comments or case briefs on these preliminary results. The deadlines are set at 21 days after the publication of the notice for main comments and 5 days later for rebuttal comments. Parties are asked to include a summary at the start of their briefs.
If anyone wants a public hearing about these results, a written request must be submitted within 30 days of the notice’s publication.
Assessment and Cash Deposit Requirements
After the final results, Commerce and U.S. Customs and Border Protection will assess duties on the entries reviewed. If the company-specific rates are not zero or very low (de minimis), duties will be collected at those rates. If margins are very low or zero, the entries will not have duties collected.
New cash deposit rates will be set for future imports as follows:
- For companies getting a separate rate, the new cash deposit rate will be based on the final review results.
- Companies not reviewed or without a separate rate will keep their current rates, including the higher China-wide rate of 285.63%.
Importer Responsibilities
Importers must file certificates stating whether they were reimbursed for antidumping or countervailing duties. Not doing so can lead to the assumption that reimbursement happened, resulting in doubled duties.
When Results Become Final
Final results are expected within 120 days after this notice. All procedures follow U.S. law as cited in the Federal Register notice.
