BC Mill Cut 40%: Sinclar Reduction Tightens SPF Supply

Impact on Your Procurement Strategy

The announcement that Sinclar Group will cut production by 40% at its three British Columbia sawmills, effective October 27, represents a sudden and significant shock to the Western SPF supply chain. This is not merely a localized event; it removes a substantial volume of key construction lumber (2x4, 2x6, studs) from the market starting next week, equivalent to one mill’s annual output.

For procurement managers, the immediate impact will be felt in two areas: pricing and lead times. Despite the seasonal slowdown typically seen in Q4, this supply retraction guarantees upward pressure on Western SPF pricing. Buyers should anticipate prices to firm quickly, reversing any recent seasonal dips, particularly in the US West and Midwest regions which depend heavily on BC rail and truck logistics. While the exact price surge is hard to predict, market tightness suggests a potential 5-8% increase in spot prices over the next 30 days as distributors scramble to cover immediate needs.

Sinclar explicitly cited the compounding challenges of fiber supply uncertainty, provincial policy conditions, and US duties/tariffs. This confirms that the contraction in BC lumber capacity is structural and long-term, not temporary. Every major curtailment reinforces the strategic need to diversify sourcing away from Western Canada. The continued threat of US tariffs adds economic insulation for US South producers (SYP), making them a more stable long-term source. This event validates a higher baseline price expectation for SPF entering 2026, regardless of short-term demand fluctuations.

To manage risk, buyers must immediately review their existing Q4 allocations and secure coverage. Expect lead times for specific-length or specialty SPF items to stretch by 1 to 2 weeks. We recommend actively exploring substitution options. While SYP and Eastern SPF are not perfect replacements, increasing their share in your inventory mix can buffer your exposure to the increasing volatility and fragility of the BC supply system. Proactive communication with your primary suppliers starting this week is critical to confirm that your allocated volume remains secure post-curtailment.

Key Takeaways

• Prioritize securing Western SPF inventory for Q4 needs immediately, especially 2x4 and 2x6 construction grades, before the 40% supply cut impacts spot markets next week.

• Anticipate increased price disparity between Western SPF and SYP/Eastern SPF. Evaluate feasibility of substituting SYP for framing packages where building codes permit.

• Recognize this as a structural trend: chronic fiber issues and US tariffs are permanently reducing BC capacity. Budget for higher baseline SPF pricing starting in 2026.

Market Outlook

Pricing Trend: UP Confidence Level: MEDIUM Recommended Action: Immediately secure Western SPF inventory needed through early Q1 2026, focusing on studs and common dimensions. Expect price firming and lead times stretching 1-2 weeks starting Nov 1. Use SYP or Eastern SPF as substitutes to reduce reliance on BC supply.
