US International Trade Commission Starts Five-Year Review of Calcium Hypochlorite Orders on China

Estimated reading time: 4–6 minutes

The United States International Trade Commission (USITC) has started new five-year reviews of the antidumping and countervailing duty orders on calcium hypochlorite from China. These reviews are required by law and will decide if canceling the orders would cause injury to US industry.

The orders were first put in place on January 30, 2015. They were continued once before in 2020. Now, as of June 2, 2025, the second review is happening.

All interested parties must send information to the USITC by July 2, 2025, to be considered. Comments on how good the responses are can be sent by August 13, 2025.

Anyone wanting more information can contact Jesse Sanchez at the USITC’s Office of Investigations. General information about the USITC is available at https://www.usitc.gov and case records can be seen at https://edis.usitc.gov.

Details About the Review

The reviews are about calcium hypochlorite from China. The USITC wants to know if ending the orders would hurt the US industry soon. The rules for this review are in 19 CFR parts 201 and 207.

  • The “Subject Merchandise” is calcium hypochlorite from China.
  • The “Domestic Like Product” is US-made calcium hypochlorite.
  • The “Domestic Industry” is all US producers of that product.
  • Companies who only convert, not make, calcium hypochlorite are not counted as US producers for this review.

How to Participate

People or groups, such as industrial users or consumer groups, who want to be part of the review must file an entry of appearance within 21 days after June 2, 2025. The USITC keeps a public list of all parties.

Old Commission members can take part in these reviews even if they worked on past cases about the same matter, according to federal rules.

Some information must be protected as business proprietary. Those wanting access must apply for an administrative protective order within 21 days after June 2, 2025.

Any party giving the USITC information must certify it is correct to the best of their knowledge. Information may be shared within the government for official use and for cybersecurity.
