About heading 4411
Fiberboard of wood or other ligneous materials, whether or not bonded with resins or other organic substances
Heading 4411 covers fiberboard made of wood or other ligneous materials, whether or not bonded with resins or other organic substances. The heading is split first by product type: medium density fiberboard (MDF) lines 4411.12 through 4411.14 are grouped by thickness, and the remaining lines 4411.92 through 4411.94 are grouped by density. Within each group, classification then turns on whether the board is mechanically worked or surface covered, and whether it is tongued, grooved or rabbetted for building use.
Full guide to heading 4411Products in this heading

Frequently asked questions
What is the HTS code for MDF panels over 9 mm thick that are not surface covered?
Unworked, uncovered medium density fiberboard over 9 mm thick is classified under 4411.14.10.00, with a general (MFN) rate of Free.
What is the duty on MDF standard wood molding?
Standard wood molding of MDF falls under 4411.14.90.10 when over 9 mm thick and under 4411.13.90.10 when over 5 mm but not over 9 mm. Both carry a general (MFN) rate of 3.9%.
How do I classify fiberboard tileboard for wall construction?
Fiberboard of a density exceeding 0.8 g/cm3 that is continuously worked along its edges and dedicated for walls, ceilings or other building parts is classified under 4411.92.30.00, with a general (MFN) rate of Free. Fiberboard over 0.5 but not over 0.8 g/cm3 that is tongued, grooved or rabbetted for building use and not laminated with synthetic resins goes under 4411.93.30.00, also Free.
