The U.S. Department of Commerce has begun an investigation to check if certain imports are breaking trade laws. This inquiry is focused on spray-foam systems from Canada that use special esters made in China.

The inquiry was requested by ICL-IP America, Inc. They believe that some imports are avoiding rules that were put in place on products from China.

The antidumping and countervailing duty rules are meant to stop unfair trade practices. These rules make sure that products are not sold at unfairly low prices in the U.S. The rules also stop countries from giving extra help to their industries unfairly.

The review will decide if spray-foam systems from Canada are being made with parts from China in a way that breaks these rules. If the products are found to be breaking the rules, new charges could be placed on them.

This process started after ICL-IP America, Inc. filed requests. They asked for an inquiry back in March 2026. They said the imports might not be following existing orders that started in June 2025.

The Department of Commerce sent questions to get more information from ICL-IP America in March and May 2026. They answered these questions in April and May 2026.

The Department of Commerce has set up rules to guide this inquiry. They include checking if the making of the spray-foam systems is a minor part that helps avoid the rules.

Once the inquiry is finished, the Department of Commerce will decide if changes are needed. If products are found to be breaking the rules, suspension of trade and extra charges might happen.

The inquiry will keep going throughout the year. The aim is to protect fair trading practices between countries. The findings might lead to changes for businesses that import these goods. They will need to watch for updates from the Department of Commerce. This will help them comply with any new rules that are made.
