U.S. Decides on Antidumping Duties for Difluoromethane from China

Estimated reading time: 4–6 minutes

The U.S. Department of Commerce has made a decision about the duties on a chemical called Difluoromethane (R-32) from China. This chemical is used in air conditioners and refrigeration. The decision is part of a process called a sunset review.

What is a Sunset Review?

A sunset review is a check to see if stopping a duty would cause the problem to start again. Duties are extra costs added to products from other countries. These are added to protect U.S. businesses from unfair pricing.

Background of the Order

In 2021, the U.S. put an antidumping duty on Difluoromethane from China. The duty was due to reports that China was selling the chemical at a very low price, hurting U.S. businesses.

Recent Developments

In February 2026, Commerce started its first sunset review of this order. A group of U.S. producers showed that they wanted the duty to continue. They believe ending it would let China sell Difluoromethane cheaply again.

Commerce did not get responses from other interested parties. Because of this, Commerce decided to do an expedited review, which is faster than the regular one.

Conclusion of the Review

Commerce decided that if the duty were removed, dumping would likely begin again. It decided the dumping margin, or amount by which the product is sold below market value, could be as high as 221.06%.

Next Steps and Notifications

The Commerce Department will notify relevant parties of this decision. This includes those involved with trade and duties. This reminder is important for parties who had access to special or private information during the review. They must follow rules on handling this information after the review ends.

This decision shows how the U.S. tries to ensure fair play in trade and protect its industries from unfair practices by other countries.
