Heading 4411

Fiberboard of wood or other ligneous materials, whether or not bonded with resins or other organic substances

36 declarable lines

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.

Products in this heading

Medium density fiberboard (MDF) panels for cabinet and furniture making
MDF boards laminated or impregnated with synthetic resins
MDF standard wood molding profiles
High density fiberboard (density over 0.8 g/cm3) sheets
Fiberboard tileboard worked along the edges for wall or ceiling installation
Bitumen-impregnated low density fiberboard panels
Uncoated fiberboard sheets with only an oil treatment

How to choose the right subheading

Whether the board is medium density fiberboard (MDF) or another fiberboard, which sends it to the 4411.12 to 4411.14 group or the 4411.92 to 4411.94 group
For MDF, the thickness of the board: not exceeding 5 mm, over 5 mm but not over 9 mm, or over 9 mm
For other fiberboard, the density: over 0.8 g/cm3, over 0.5 but not over 0.8 g/cm3, or not over 0.5 g/cm3
Whether the board is mechanically worked or surface covered, which moves it out of the duty-free unworked lines
Whether the board is tongued, grooved or rabbetted along its edges and dedicated for walls, ceilings or other building parts

Often confused with

Particle board and oriented strand board (OSB)
These are agglomerated with resins from wood particles or strands, not fiberboard.
Heading 4410
Plywood and veneered panels
Laminated wood products built from veneer layers are classified in 4412.
Heading 4412
Wood continuously shaped into moldings, tongued or grooved along edges
Solid wood moldings and shaped strips go to 4409, while worked fiberboard moldings stay in 4411.
Heading 4409
Assembled flooring panels and builders' joinery of wood
Panels assembled into joinery or flooring are classified in 4418.
Heading 4418
Veneer sheets under 6 mm thick
Sliced or peeled sheets for veneering are classified in 4408, not as fiberboard.
Heading 4408

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.
