HS Code for Western hemlock lumber

Western hemlock lumber is classified under HS code 4407.14. Chapter 44 covers wood and articles of wood, with heading 4407 specifically addressing wood sawn or chipped lengthwise, sliced or peeled, whether or not planed, sanded, or end-jointed, of a thickness exceeding 6 mm. Within this heading, the Harmonized System differentiates between coniferous and non-coniferous species. Subheading 4407.14 is a specific category for coniferous wood of the "Hem-fir" group, which includes Western hemlock (Tsuga heterophylla) and various species of fir (Abies spp.). This classification is used because these species are often harvested, processed, and marketed together in the timber industry due to their similar structural properties. To qualify for this code, the lumber must be processed beyond simple logs but must not be worked into specific shapes like moldings or beadings. The thickness requirement of over 6 mm is a critical threshold for classification under 4407. If the wood is thinner than 6 mm, it would likely fall under heading 4408 for sheets for veneering.

Common Misclassification

This product is frequently confused with HS code 4403, which covers wood in the rough. If the Western hemlock has not been sawn or chipped lengthwise into boards or planks, it remains in 4403. Additionally, if the lumber has been further processed into continuously shaped wood—such as tongue-and-groove flooring or decorative molding—it must be classified under 4409. Confusion also arises with 4407.11 (Pine) or 4407.12 (Fir and Spruce) if the specific species is not clearly identified on the commercial invoice. Since 4407.14 specifically groups Hemlock and Fir, accurate botanical identification is necessary for correct entry.
