The separate rating systems for framing lumber strength were established by the U.S. and Canada in the early 1990s. Despite the wood itself being nearly identical, the American SPFs classification received a lower design strength value. This discrepancy has, over time, provided a competitive edge to Canadian lumber, placing New Hampshire lumber at a market disadvantage.
Proponents of the bill argue that the measure is a step toward having designers, architects, and engineers acknowledge the specific specification required for American wood in state projects. The intent is to promote domestically harvested products and to address cost considerations, as one industry representative noted a price difference for a specific lumber dimension between Canadian and New Hampshire sources.
While legislative action cannot alter international industry standards, it can direct how the state procures materials for its own construction needs. The bill received approval from New Hampshire lawmakers.
