Many homeowners and contractors in Western Canada will soon be
asking "Why do I have to pay antidumping duties on imports of
gypsum board or drywall?" This is because there is an
antidumping case in Canada on gypsum board imported from the United
States into Western provinces.
Starting on September 6, 2016, imports of drywall/gypsum board
into Western Canada (British Columbia, Alberta, Saskatchewan and
Manitoba, and the Yukon and Northwest Territories) will be subject
to antidumping duties. This is because CertainTeed filed an
antidumping case on gypsum board originating in and/or exported
from the United States and the Canadian International Trade
Tribunal made preliminary determination of injury on August 5,
2016. No exclusion was granted for small volumes of drywall
imported by homeowners or contractors (sorry, we tried
The preliminary antidumping duty rates will be announced by the
Canada Border Services Agency ("CBSA") on September 6th
if there is a preliminary determination of dumping (which is
expected). All imports of subject drywall/gypsum board on September
6, 2016 and thereafter until the final determination of duties will
be subject to the preliminary duty rate.
The new added expense will come as a surprise to homeowners and
contractors who live near the U.S./Canada border. Just as people
are finishing summer renovation projects and summer construction of
new residential complexes, the price could double. The amount of
the duties can be at any level (even over 100%). Many individuals
are closer to a building supply store on the US side of the border.
Homeowners will have to change their buying habits and drive
further for CertainTeed drywall stocked at a Canadian retail store
or pay the premium duties at the border.
