U.S. imports of High-Density Fiberboard (HDF), Density Exceeding 0.8 g/cm³, NESOI (HS 441192) totaled $7.3M in August 2026, imported from 21 countries.
Importers of High-Density Fiberboard (HDF), Density Exceeding 0.8 g/cm³, NESOI paid $1.1M in duties in August 2026, an average duty rate of 15.38% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. High-Density Fiberboard (HDF), Density Exceeding 0.8 g/cm³, NESOI imports of $7.3M in August 2026 ran 23% above the year-to-date monthly average of $5.9M.
Last updated: August 2026 dataFiberboard with a density above 0.8 g/cm³—commonly called hardboard or HDF—is a distinct product from MDF, manufactured under higher pressure to achieve a harder, denser surface used in flooring underlayment, pegboard, door facings, and tempered panel applications. Five 10-digit lines cover this heading, including unworked panels (4411921000), non-surface-covered panels excluding oil treatment (4411922000), tileboard with worked edges for construction (4411923000), mechanically worked or surface-covered panels (4411924000), and a residual NESOI line (4411925000). Canada leads US supply, with Brazil and Spain also significant sources. Importers should be aware that tileboard (4411923000) carries a specific construction-use definition tied to worked edges, making product specification documentation important for correct line-level classification.

The dividing line is density: fiberboard exceeding 0.8 g/cm³ falls under heading 441192 as hardboard or HDF, while medium-density fiberboard (MDF) covers the 0.35–0.8 g/cm³ range under headings 441112–441114. Hardboard is typically produced without added resin binders, relying on lignin activation under heat and pressure, whereas MDF uses urea-formaldehyde or similar resins. This distinction also affects TSCA Title VI applicability.
Tileboard under 4411923000 is specifically fiberboard of wood or other ligneous materials with a density exceeding 0.8 g/cm³ that has been worked on its edges for construction use—typically a surface-printed or embossed panel with profiled edges designed to simulate tile in bathroom or kitchen wall applications. The worked-edge construction requirement is the key distinguishing feature; flat hardboard panels without such edge treatment would classify under other lines in this heading.
