U.S. International Trade Commission Schedules Expedited Reviews for Calcium Hypochlorite from China
Estimated reading time: 1–7 minutes
On December 9, 2025, the United States International Trade Commission (ITC) announced the scheduling of expedited five-year reviews. These reviews are for antidumping and countervailing duty orders on calcium hypochlorite from China. The aim is to decide if ending these orders would likely lead to continued or future harm to the U.S. industry.
The Commission noted its decision was based on responses received by September 5, 2025. The domestic interested party group gave an adequate response. However, the respondent group’s response was inadequate. There were no other reasons to conduct a full review. As a result, the Commission will move forward with expedited reviews following section 751(c)(3) of the Tariff Act of 1930 (19 U.S.C. 1675(c)(3)).
There was also a mention of time delays. These were due to a lack of funding and a temporary stop in Commission operations. This caused deadlines in the case to be tolled, or paused.
For additional procedures and rules, the notice refers to the Commission’s Rules of Practice and Procedure. These are listed under 19 CFR part 201 and 19 CFR part 207, which cover different parts of the process.
A staff report about these reviews is on the Commission’s nonpublic record. It will be shared with people under the Administrative Protective Order on January 9, 2026. A public version will be made available later, under the Commission’s rules.
Written comments can be filed by January 15, 2026. Only interested parties that provided adequate responses may submit these comments. Comments cannot contain new factual information. Other parties not involved in the reviews may submit brief written statements by the same date, also without new facts. If comments have sensitive business information, they must meet the rules in 19 CFR 201.6, 207.3, and 207.7. The Commission has found that only responses from Innovative Water Care LLC were individually adequate, so comments from other interested parties will not be accepted.
Every document filed by a party must be sent to all other parties. A certificate of service must also be filed. The Secretary will not accept any document without it.
The Commission has found these reviews are extraordinarily complicated. Therefore, they are extending the review period by up to 90 days, using their authority under 19 U.S.C. 1675(c)(5)(B).
This process is part of the ITC’s work under the Tariff Act of 1930, as noted by the official order. The notice was issued by Lisa Barton, Secretary to the Commission, on December 5, 2025.
