How Canada’s New OCTG Tariff Rate Quota System Affects Your 2026 Procurement Strategy And What to Do About It
If you’re sourcing Oil Country Tubular Goods (OCTG) for Canadian operations, the rules changed last summer and the full weight of those changes is being felt right now.
Canada’s Tariff Rate Quota (TRQ) system, which came into force in mid-2025, has fundamentally restructured how imported OCTG and linepipe moves through the supply chain. Modest quarterly quotas, steep overage surtaxes, an additional levy on Chinese-melted steel, and a new wave of anti-dumping investigations have made what was once a relatively straightforward procurement process significantly more complex.
At Imex Canada, we work through these regulations every day on behalf of our clients. This guide breaks down what the TRQ system actually means in practice and how to position your procurement strategy to avoid costly surprises in 2026.
What Is the OCTG Tariff Rate Quota (TRQ) System?
The TRQ system was introduced by the Canadian government to protect domestic OCTG and linepipe producers from diverted steel flows particularly material redirected toward Canada after the United States imposed its own steel tariffs. The policy prioritizes Canadian-made material for domestic projects and tightens the import channel for foreign-sourced tubulars.
The system took effect in two stages: June 27, 2025 for non-Free Trade Agreement (FTA) countries, and August 1, 2025 for FTA exporters (excluding the US and Mexico).
Here is what it means in practical terms:
Small quarterly quotas. Allowable import volumes are modest for example, roughly 7,800 tonnes per quarter for OCTG from non-FTA origins and approximately 5,000 tonnes per quarter for large-diameter linepipe. These quotas are administered on a first-come, first-served basis, with no breakdown by country, supplier, or product type.
A 50% surtax on overages. Once quarterly quotas are exhausted, all subsequent shipments arriving at Canadian ports are subject to a 50% surtax. There is no grace period and no advance warning the quota depletes as shipments arrive.
An additional 25% levy on Chinese-melted steel. Imports that include Chinese-melted steel face an extra 25% charge on top of existing duties, significantly restricting viable supply options for buyers who have historically relied on Chinese mills.
First-come, first-served with no transparency. Because there is no breakdown by country or product type, buyers and suppliers have no reliable way to know how much quota remains at any given time. This has led many suppliers to issue dual-price offers to Canadian buyers one price assuming the shipment clears within quota, and a second higher price that accounts for the surcharge if the quota has already been exhausted by the time the shipment arrives.
The Anti-Dumping Layer: New CBSA Investigations in 2025
The TRQ system isn’t the only regulatory development reshaping the Canadian OCTG market. In late 2025, the Canada Border Services Agency (CBSA) issued a preliminary ruling imposing provisional anti-dumping duties on certain OCTG imported from Mexico, the Philippines, Turkey, South Korea, and the United States. Estimated dumping margins in the preliminary ruling ranged from 5.3% to 148.4% depending on origin and supplier.
These duties are payable from December 22, 2025, and remain in effect while the investigation concludes. Combined with the TRQ surtaxes, they add a significant and unpredictable cost layer to OCTG procurement from a broad range of traditional supply origins.
For Canadian buyers, this means the question is no longer just what grade and weight do I need it’s which supply origin is compliant, available within quota, and cost-competitive right now?
What This Means for Your Procurement Strategy in 2026
The combined effect of the TRQ system and the new anti-dumping duties is tighter supply, higher baseline costs, and significantly reduced flexibility in sourcing decisions. Here is how that plays out:
Qualification requirements make substitution difficult. OCTG must meet specific API grade and connection specifications for each well program. You cannot simply swap to a different supplier or origin at the last minute because a quota has been exhausted your casing and tubing program is designed months in advance. Late-quarter cost surges are a real risk for buyers who haven’t locked in supply early.
Project-heavy quarters will be volatile. Quota exhaustion will be uneven and unpredictable. During high-demand quarters when multiple operators are simultaneously purchasing material for major projects quotas will deplete faster, surtaxes will kick in earlier, and domestic mill pricing power will increase. Buyers without advance supply commitments will pay more or wait longer.
Dual-price offers are becoming standard. If your supplier is now quoting you two prices one with and one without the surtax that is not a negotiating tactic. It reflects genuine uncertainty about whether your shipment will clear within quota. Understanding this dynamic is important when comparing bids from multiple suppliers.
Chinese-melted steel is effectively penalized. The additional 25% levy on Chinese-melted content materially changes the landed cost calculus for a significant portion of the global OCTG supply base. Suppliers with transparent, documented mill certifications and clear country-of-melt traceability are now at a meaningful advantage.

Key Takeaways for OCTG Buyers in 2026
To summarize what every procurement and supply chain professional working with Canadian OCTG needs to keep in mind right now:
- Quotas are small and deplete fast 7,800 tonnes/quarter for OCTG from non-FTA origins is not a large buffer for a market with active pipeline and upstream drilling programs.
- The 50% surtax is automatic once quota is gone there is no application process, no exemption, and no retroactive relief.
- Chinese-melted steel carries an additional 25% levy mill traceability documentation is now a procurement essential, not a nice-to-have.
- New anti-dumping duties from late 2025 affect imports from Mexico, the Philippines, Turkey, South Korea, and the US expanding the list of affected origins well beyond China.
- Qualification requirements mean you cannot switch origins at short notice lock in your supply early, especially for project-heavy quarters.
- A qualified, experienced supply partner is no longer optional the complexity of the current regulatory environment makes expert customs guidance a direct cost-saver.
