On March 1, 2010, the Canadian International Trade Tribunal announced that it decided not to file the mid-term review of antidumping and antisubsidy on drywall screws originating in China mainland and Chinese Taipei.

On January 6, 2010, the Tribunal found that the resumed dumping of certain carbon steel fasteners from China and Chinese Taipei, and the resumed subsidizing of such products from China were likely to cause injury to the domestic industry. The Canada Border Services Agency (CBSA) will therefore continue to impose anti-dumping and countervailing duties on these products. The Tribunal also found that the dumping of certain stainless steel fasteners from Chinese Taipei was unlikely to result in injury. The CBSA will therefore not continue to impose anti-dumping duties on these products.

On January 22, 2010, a Canadian company called Leland Industries Inc. applied to the Canadian International Trade Tribunal, claiming that the drywall screws should not be excluded from the product concerned, thus requiring a mid-term review of antidumping and antisubsidy investigations on drywall screws originating in China mainland and Chinese Taipei. The Canadian International Trade Tribunal considered that if the drywall screws were included in the product concerned, they should modify the customs codes of the product concerned. While according to relevant laws and regulations in Canada, the Tribunal does not initiate reviews on products that are out of the product concerned. Therefore, the Tribunal found it not to file the mid-term review of antidumping and antisubsidy on drywall screws originating in China mainland and Chinese Taipei.
