April has brought a wave of trade remedy activity affecting Canadian importers across several sectors. The Canada Border Services Agency (CBSA) and Canadian International Trade Tribunal (CITT) have initiated new investigations, finalized one major determination, and launched an expiry review — all with direct implications for tariff exposure and landed cost.
Decorative and Other Non-Structural Plywood from China (DONP2 2026)
On April 10, 2026, CBSA initiated dumping and subsidy investigations under the Special Import Measures Act (SIMA) into decorative and other non-structural plywood from China. The complaint was filed by Columbia Forest Products of Hearst, Ontario, and the Canadian Hardwood Plywood and Veneer Association of Saint-Sauveur, Quebec.
The investigation covers multilayered plywood panels — surface coated or uncovered — meeting ANSI/HPVA HP-1-2024 standards, classified under 15 tariff codes ranging from 4412.10.00.00 to 4412.99.00.00. Structural plywood meeting CSA or U.S. standards, finished flooring, non-flat panels, phenolic film-faced plyform, and specialized door components are excluded from the scope.
On April 13, 2026, the Canadian International Trade Tribunal initiated a parallel preliminary injury inquiry (PI-2026-001). A preliminary determination from CBSA is expected by approximately July 9, 2026, with provisional duties possible at that stage. The investigation is scheduled to conclude by October 7, 2026.

Oil Country Tubular Goods 5 (OCTG5 2025) — Final Determination
On April 7, 2026, CBSA issued its Statement of Reasons for the final determination in the OCTG5 dumping investigation covering certain oil country tubular goods originating in or exported from Mexico, the Philippines, Türkiye, the Republic of Korea, and the United States. The final determination was rendered on March 23, 2026.
The investigation was dumping-only — no subsidy finding was pursued. Provisional duties that accrued earlier in the investigation will be formalized pending the CITT’s final injury determination. Importers of OCTG from the named countries should review duty assessments on shipments imported during the investigation period and be prepared for finalized anti-dumping duty rates once the CITT concludes its inquiry.

Whole Potatoes (POT 2026 ER) — Expiry Review
On April 1, 2026, the Canadian International Trade Tribunal initiated an expiry review (RR-2026-001) under subsection 76.03(1) of SIMA into the existing anti-dumping measures on certain whole potatoes exported from the United States for use or consumption in British Columbia, originally ordered on June 2, 2021. CBSA has until August 28, 2026 to determine whether expiry of the order would likely lead to continued or resumed dumping; if so, the CITT has until February 4, 2027 to rule on likelihood of injury to the domestic industry. Importers, producers, and exporters wishing to participate should monitor CBSA and CITT notices for scheduling and submission deadlines.

What This Means for Importers
With plywood, OCTG, and potatoes all in active trade remedy proceedings, importers should confirm country-of-origin documentation, review tariff classifications carefully, and assess potential provisional-duty exposure on in-transit and future shipments.
