Investigation into dumping of 54-inch gypsum board from the U.S.

The Canada Border Services Agency (CBSA) launched an investigation on June 21, 2018 respecting the alleged dumping of certain 54-inch gypsum board from the U.S. imported into Canada for use or consumption in the provinces of British Columbia, Alberta, Saskatchewan, and Manitoba, as well as the Yukon and Northwest Territories.

The investigation is the result of a complaint filed by a manufacturer in Ontario. The complainant alleges that the dumped goods have caused material retardation to the domestic industry in Western Canada.

In the next step of the investigations the Canadian International Trade Tribunal will first determine whether the imports are harming Canadian producers, and will issue a decision by August 20, 2018.

Concurrently, the CBSA will investigate whether the imports are being sold in Canada at unfair prices, and will make a preliminary decision by September 19, 2018.

Anti-dumping duties could eventually be applied to the goods under investigation.
