The Canadian International Trade Tribunal (CITT) is continuing its inquiry into the question of injury to the Western Canadian industry and will make an order or a finding by January 4, 2017.

Provisional duties will continue to apply on imports of subject goods from US until the date of the CITT’s order or finding.

Margins of Dumping by Exporter
Exporter Margin of Dumping*

CertainTeed Gypsum and Ceiling Manufacturing Inc. 211.0%
Georgia-Pacific Gypsum LLC 94.6%
United States Gypsum Company 201.0%
All Other Exporters 324.1%

NOTE: The margins of dumping reported in the table above are the margins determined by the CBSA for purposes of the final determination of dumping. These margins do not reflect the amount of anti-dumping duty to be levied on future importations of dumped goods. In the event of an injury finding by the CITT, normal values have been provided to the exporters which provided sufficient information for future shipments to Canada and these normal values would come into effect the day after an injury finding. Imports from exporters/producers that did not provide sufficient information to the CBSA during the dumping investigation and who are not listed in the table above will be subject to the All Other Exporters anti-dumping duty rate of 324.1%, expressed as a percentage of the export price. Please consult the SIMA Self-Assessment Guide for more detailed information explaining how to determine the amount of SIMA duties owing.

Normally, normal values will not be applied retroactively. However, this measure may be applied retroactively in cases where the parties have not advised the CBSA in a timely manner of substantial changes that affect values for SIMA purposes. Therefore, where substantial changes occur in prices, market conditions, costs associated with production and sales of the goods, the onus is on the concerned parties to advise the CBSA.
