International Trade Commission Begins Expedited Review of Difluoromethane (R-32) from China

Estimated reading time: 3–5 minutes

The United States International Trade Commission (USITC) has announced the start of an expedited review for difluoromethane (R-32) from China. This review will examine if ending the antidumping duty on this product would lead to injury to domestic industries.

The review is conducted under the Tariff Act of 1930. The USITC is looking to see if removing the duties will harm American businesses that make similar products. The decision to expedite the review means it will be faster than a normal review.

On May 8, 2026, the Commission looked at responses from interested parties. While the domestic parties gave strong responses, the response from the other side was found weak. This led the USITC to decide on an expedited review process.

A staff report with more details will be ready by June 24, 2026. After this, interested parties can send in their written comments. The deadline for these comments is July 1, 2026. These comments will help the Commission make its final decision.

If the Department of Commerce takes more time for its final results, the comment deadline will be three days after Commerce’s report. Any comments with confidential business information have to follow specific rules when submitted.

USITC’s authority allows it to extend the review period by up to 90 days if necessary. This review is part of an important process to ensure fair trade practices.

The review by the USITC will help decide if the duties on difluoromethane from China should stay in place. Keeping these duties could protect American industries from unfair competition. The outcome will impact both trading nations and is being carefully assessed to ensure fairness and fair competition.
