U.S. imports of Medium-Density Fiberboard, Density Exceeding 0.5 g/cm³ but Not Exceeding 0.8 g/cm³, NESOI (HS 441193) totaled $162K in September 2026, imported from 17 countries.
Importers of Medium-Density Fiberboard, Density Exceeding 0.5 g/cm³ but Not Exceeding 0.8 g/cm³, NESOI paid $35K in duties in September 2026, an average duty rate of 21.54% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Medium-Density Fiberboard, Density Exceeding 0.5 g/cm³ but Not Exceeding 0.8 g/cm³, NESOI imports of $162K in September 2026 ran 24% below the year-to-date monthly average of $212K.
Last updated: September 2026 dataFiberboard in the 0.5–0.8 g/cm³ density band that falls outside the MDF thickness-specific headings (441112–441114) is captured here as a residual category, covering specialty ligneous-material panels—including non-wood fiber substrates—used in acoustic panels, furniture components, and specialty construction board. Seven 10-digit lines differentiate by surface treatment and edge profile, from unworked panels (4411931000) through laminated tongue-and-groove (4411932000), ligneous tongue-and-groove (4411933000), non-surface-covered (4411936000), ligneous mechanically worked (4411938000), standard wood molding (4411939010), and NESOI (4411939090). Canada is the dominant supplier, with China and Belgium also notable sources. Classification into this NESOI heading rather than the thickness-defined MDF headings requires confirming that the product does not fall within the 441112–441114 thickness parameters.

Headings 441112–441114 apply specifically to MDF as defined in the HTS chapter notes, organized by thickness tiers. Heading 441193 is a residual NESOI provision covering fiberboard of wood or other ligneous materials in the 0.5–0.8 g/cm³ density range that does not meet the MDF definition or falls outside those thickness parameters. Products made from non-wood ligneous fibers (such as bagasse or straw board) at this density may also land here. Importers should verify the product's fiber composition and whether it meets the MDF chapter-note definition.
Potentially yes. The heading covers fiberboard of wood or 'other ligneous materials,' which can include agricultural residue-based panels such as straw board or sugarcane bagasse board, provided the density falls in the 0.5–0.8 g/cm³ range and the product is not more specifically described elsewhere. Correct classification depends on the fiber composition and manufacturing process; a binding ruling from CBP is advisable for novel substrate products.
