Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If surfaced or planed into dimensional lumber
Worked Hem-fir lumber moves to heading 4407 coniferous sawn wood.
If particleboard made from residues
Agglomerated wood from shavings/chips of such poles classifies under particleboard.
If used in complete wind turbine towers
Parts of hydraulic turbines or specific machinery take precedence over wood classification.

Import Tips & Compliance
• Comply with TSCA Title VI for formaldehyde if any binders used; pure preservative treatment exempt
• Declare exact species mix; 'Hem-fir' note applies but requires proof of mixed stand origin
• Inspect for sapwood removal; incomplete stripping risks downgrade to unworked wood
