U.S. imports of densified wood in blocks, plates, strips, or profile shapes (SITC 63421) totaled $2.4M in April 2026, traded with 16 countries.
Importers of Densified Wood in Blocks, Plates, Strips, or Profile Shapes paid $283K in duties in April 2026 — an effective duty rate of 14% on $2.1M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataDensified wood — produced by compressing wood under heat and pressure, sometimes with resin impregnation — achieves hardness and wear resistance approaching that of metals, making it a specialized engineering material for bearings, gears, electrical insulation, and tooling applications. The compression process fundamentally alters the wood's cellular structure, and the resulting product is classified by its physical form: blocks, plates, strips, or profile shapes. This is a niche industrial material with a distinct supply chain separate from conventional lumber or panel products.

Densified wood is used in applications requiring high compressive strength and low friction, including underwater bearings for propeller shafts, electrical transformer insulation boards, die-cutting blocks, and precision tooling jigs. Its combination of machinability and mechanical performance makes it a cost-effective alternative to engineering plastics or non-ferrous metals in certain applications.
Densified wood is characterized by compression of the wood's own cellular structure — often with resin impregnation — resulting in a homogeneous, extremely dense material. Laminated wood or plywood consists of distinct layers bonded together. A density measurement and cross-section examination can confirm the distinction; densified wood typically exceeds 1,000 kg/m³, well above normal wood density.
