U.S. imports of Reconstituted Wood Products (NAICS 321219) totaled $254.2M in August 2026, imported from 63 countries.
Importers of Reconstituted Wood Products paid $14.1M in duties in August 2026, an average duty rate of 5.56% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataReconstituted wood products — including particleboard, medium-density fiberboard (MDF), oriented strand board (OSB), and hardboard — are manufactured by breaking down wood into fibers, particles, or strands and rebonding them with adhesives under heat and pressure, producing panels with consistent properties not achievable with solid wood. MDF and particleboard are widely used as substrate materials in furniture, cabinetry, and flooring, while OSB dominates structural sheathing applications in US homebuilding. Formaldehyde emissions from the adhesive resins used in these products are regulated under EPA TSCA Title VI, and all imported reconstituted wood panels must meet applicable emission standards before entering US commerce.

OSB is currently exempt from TSCA Title VI formaldehyde emission limits because its manufacturing process uses phenol-formaldehyde resins that emit at very low levels. MDF, particleboard, and hardwood plywood are the primary regulated panel types. Importers of OSB should still verify current EPA guidance, as regulatory scope can be updated.
MDF is produced from finer wood fibers, yielding a smoother, denser surface that accepts paint and veneer well and machines cleanly for routed profiles — making it preferred for painted cabinet doors and molded components. Particleboard uses coarser wood particles, is less dense, and is typically used as a lower-cost substrate for flat surfaces laminated with foil or melamine. Density, screw-holding strength, and surface smoothness are the key specification differences buyers evaluate.
