U.S. imports of medium density fiberboard (mdf), thickness not exceeding 5 mm (HS 441112) totaled $10.3M in April 2026, traded with 24 countries.
Last updated: April 2026 dataThin-panel MDF at or below 5 mm is a specialty substrate widely used in furniture backing, cabinet components, and decorative overlays where minimal thickness and smooth surface uniformity are critical. The US tariff schedule breaks this heading into seven 10-digit lines—including unworked panels (4411121000), laminated tongue-and-groove boards (4411122000), ligneous tongue-and-groove (4411123000), non-surface-covered panels (4411126000), mechanically worked ligneous board (4411128000), standard wood molding (4411129010), and surface-covered panels not elsewhere specified (4411129090)—distinguishing by surface treatment and edge profile. Canada leads US supply, followed by New Zealand and Brazil, reflecting proximity advantages and established softwood fiber industries. Importers should note that MDF produced with urea-formaldehyde resins is subject to EPA TSCA Title VI formaldehyde emission standards, enforced through CBP at entry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes. MDF panels containing urea-formaldehyde resins must comply with EPA TSCA Title VI emission standards. Importers are required to obtain a signed chain-of-custody statement from a TSCA Title VI-compliant panel producer or third-party certifier, and CBP may request this documentation at entry.
The seven 10-digit lines under this heading separate panels by processing state and surface condition: unworked/not surface-covered (4411121000), laminated tongue-and-groove (4411122000), ligneous tongue-and-groove (4411123000), non-surface-covered excluding oil treatment (4411126000), mechanically worked ligneous board (4411128000), standard wood molding (4411129010), and surface-covered panels NESOI (4411129090). Correct classification depends on whether edges have been profiled, whether a surface coating has been applied, and the fiber substrate type.
