CertainTeed Gypsum Canada Welcomes CITT Western Drywall Determination

Anti-Dumping Measures For Western Provinces Maintained for Another 5 Years

CertainTeed Canada Inc. welcomes the Canadian International Trade Tribunal’s decision to maintain anti-dumping measures for drywall in British Columbia, Alberta, Saskatchewan, and Manitoba, as well as the Yukon and Northwest Territories for another five years.

In an expiry review issued yesterday, the CITT found that U.S. drywall dumping will cause material injury to the domestic western Canadian drywall industry if current anti-dumping measures are not maintained.  As a result, current anti-dumping measures will be maintained for another five years.

The ruling applies to gypsum board meeting or supplied to meet ASTM C 1396 or ASTM C 1396M or equivalent standards, excluding gypsum board made to a width of 54 inches.

As stated by Julie Bonamy, CEO Certain Canada Inc.: CertainTeed Canada is committed to free and fair trade; we have helped shape the Canadian building products industry for more than 80 years.  In Western Canada, we own and operate three drywall manufacturing plants and are committed to support our customers and employees through our facilities in Vancouver, Calgary, and Winnipeg.
