2026 DOC AR7 Review Signals 5.51% Duty for Canadian SPF

Impact on Your Procurement Strategy

The US Department of Commerce (DOC) preliminary determination for the seventh administrative review (AR7) targets Canadian softwood producers with varying antidumping duties, including a 11.23% rate for Tolko and 3.53% for West Fraser. While these preliminary findings do not immediately alter the cash deposit rates currently paid at the border, they establish a high-cost trajectory for Canadian SPF imports arriving in late 2026. This regulatory update coincides with a period where supply is already tightening, as evidenced by the continued upward pressure seen across framing lumber composites over the last three weeks.

Demand remains resilient despite the high-volatility regime currently characterizing the market, with prices trading 9.2% above their 12-week moving average. Distributor inventory levels are being tested by this accelerating rally, yet the current market appears to have reached a temporary ceiling following a rapid price ascent. The 5.51% "All Others" rate serves as a signal to the market that trade friction will persist, potentially discouraging aggressive inventory drawdowns at the mill level during the upcoming Q2 2026 building season.

Procurement managers should treat this DOC announcement as a long-term cost indicator rather than an immediate trigger for speculative purchasing. Given that the market has already moved up significantly and prices have recently plateaued, the most prudent strategy is to maintain coverage through May 2026 without chasing the peak of the current rally. Buyers should prioritize suppliers like West Fraser who received lower preliminary rates ( 3.53%) compared to outliers like Tolko, as these discrepancies will eventually dictate landed cost advantages once the final determination is published in the Federal Register.

Looking ahead to Q3 2026, the combination of persistent trade duties and seasonal demand patterns suggests a floor for pricing remains firmly in place. While our internal models predict a STABLE price direction with a modest 1.0% change over the next week, the underlying momentum remains bullish until supply-side constraints ease. We expect the final AR7 determination later this year to largely mirror these preliminary figures, cementing a higher cost-of-goods-sold environment for distributors relying on Canadian fiber.

Key Takeaways

• Preliminary AR7 antidumping rates for most Canadian mills are set at 5.51%, signaling higher landed costs for SPF in late 2026.

• Current market momentum has pushed prices into overbought territory; avoid chasing the peak as the DOC news has no immediate cash impact.

• Prioritize supply from lower-rate entities like West Fraser ( 3.53%) over high-rate producers like Tolko ( 11.23%) for long-term contract planning.

Market Outlook

Pricing Trend: UP

Confidence Level: MEDIUM

Recommended Action: Maintain hand-to-mouth buying for the next 14 days to avoid overpaying during the current rally, as the DOC AR7 news will not impact cash deposit rates until late 2026.
