Canada Initiates Administrative Review of its Antidumping Duty Measure on Copper Pipe Fittings from the United States, the People’s Republic of China, and the Republic of Korea
On June 1, 2026, the Canada Border Services Agency (CBSA) initiated an administrative review of its antidumping duty/measure on imports of copper pipe fittings from the United States. Canada’s AD measure on copper pipe fittings has been in place since February 2007.
What is an administrative review?
The purpose of the administrative review is to update normal values, export prices, or subsidy amounts, as well as to establish amounts for new exporters or new products. The updated values will apply to goods released from Customs on or after the date of the conclusion of the administrative review.
