On 2 December 2025, Viet Nam received information from the Viet Nam Trade Office in Canada that the Canadian International Trade Tribunal (CITT) had issued a notice initiating a sunset review (expiry review) of the anti-dumping duty order applied to imports of Oil Country Tubular Goods (OCTG) from several countries, including Viet Nam.

The purpose of the review is to assess whether the dumping of the subject goods is likely to continue or recur if the existing order expires, and to determine the potential risk of injury to Canada’s OCTG industry. The level of anti-dumping duties is not under consideration during this review process.

The products under review include a range of OCTG items such as casing, tubing, and green tubes made of carbon steel or alloy steel; welded or seamless; heat-treated or non-heat-treated; with all end finishes; meeting API 5CT standards or equivalent; and with an outside diameter of 2 3/8″ to 13 3/8″ (60.3–339.7 mm). Exclusions include drill pipe, pup joints, couplings/coupling stock, and stainless steel pipes with a chromium content of 10.5% or higher.

Below are the key procedural milestones of the review.
