U.S. imports of Low-Density Fiberboard, Density Not Exceeding 0.5 g/cm³, NESOI (HS 441194) totaled $4.1M in September 2026, imported from 14 countries.
Importers of Low-Density Fiberboard, Density Not Exceeding 0.5 g/cm³, NESOI paid $210K in duties in September 2026, an average duty rate of 5.13% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Low-Density Fiberboard, Density Not Exceeding 0.5 g/cm³, NESOI imports of $4.1M in September 2026 ran 19% above the year-to-date monthly average of $3.4M.
Last updated: September 2026 dataLow-density fiberboard at or below 0.5 g/cm³—often called softboard or insulation board—serves primarily as thermal and acoustic insulation in construction, as well as in pin-board and display applications where lightweight and workability matter more than structural strength. The heading's eight 10-digit lines include bitumen-impregnated panels (4411940010, 4411940050), standard wood-fiber panels (4411940020), ligneous panels in the 0.35–0.5 g/cm³ sub-range (4411940040), non-surface-covered panels (4411940060, 4411941000), and surface-covered panels (4411940080, 4411948000). Canada, Poland, and Germany are the leading US suppliers, with European producers historically dominant in insulation-grade softboard. Importers should confirm density test documentation, as the 0.5 g/cm³ threshold is the classification boundary with the medium-density headings above.

CBP may request a manufacturer's technical data sheet or an independent laboratory test report confirming the panel's density in g/cm³. Because the 0.5 g/cm³ threshold separates this heading from the medium-density headings above, density certification from the foreign producer—ideally referencing the test method used (e.g., ISO 9427 or ASTM D1037)—is the most reliable supporting document. A binding ruling from CBP is advisable when density is close to the boundary.
The US schedule provides dedicated lines for bitumen-impregnated panels: 4411940010 covers panels that are not mechanically worked and are impregnated with bitumen, and 4411940050 covers non-surface-covered, bitumen-impregnated panels. These lines are distinct from the standard wood-fiber and ligneous-material lines, so importers of weather-resistant or damp-proof insulation board treated with bitumen should confirm the correct line based on whether the panel has also been mechanically worked or surface-covered.
