Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If smallest cross-sectional dimension is less than 15 cm
Subheading distinguishes by size; smaller dimensions fall into the prior statistical breakout within same heading.
If sawn or chipped lengthwise, thickness >6mm, Hem-fir mixed stands
Processed hemlock lumber moves to Chapter 44 sawn wood headings; Hem-fir note applies to mixed hemlock-fir sources.
If fuelwood in log form, not squared
Coniferous fuelwood logs classify under 4401 regardless of size if primary end-use is burning rather than lumber.

Import Tips & Compliance
• Obtain CITES certification if logs exceed regulated volumes; Western hemlock is not typically Appendix-listed but verify origin
• Provide phytosanitary certificate confirming no bark/stripwood pests; fumigation may be required for ISPM 15 compliance
• Measure cross-section accurately—logs under 15cm shift to 4403.25.0100; declare exact species to avoid reclassification
