The Canada Border Services Agency (CBSA) started an anti-dumping (AD) investigation on February 2, 2026, targeting oil and gas well casing from Austria.

Following a complaint from Tenaris Canada, the inquiry examines whether these imports cause injury to the domestic market. Preliminary findings are due within 90 days, potentially resulting in provisional duties.

The scope includes welded or seamless carbon or alloy steel casing and green tube casing with outside diameters between 114.3 mm and 245.2 mm. These products must meet API 5CT or equivalent standards. The investigation specifically excludes drill pipe, pup joints, unattached couplings, coupling stock, insulated tubing and vacuum insulated tubing, and stainless steel casing containing 10.5% or more by weight of chromium.

These subject goods are under HS codes 7304.29.00.12, 7304.29.00.13, 7304.29.00.14, 7304.29.00.15, 7304.29.00.16, 7304.29.00.17, 7304.29.00.19, 7304.29.00.22, 7304.29.00.23, 7304.29.00.24, 7304.29.00.25, 7304.29.00.26, 7304.29.00.27, 7304.29.00.29, 7306.29.00.12, 7306.29.00.13, 7306.29.00.14, 7306.29.00.15, 7306.29.00.16, 7306.29.00.17, 7306.29.00.19, 7306.29.00.22, 7306.29.00.23, 7306.29.00.24, 7306.29.00.25, 7306.29.00.26, 7306.29.00.27, and 7306.29.00.29.
