HS Code for Hardboard

Hardboard is classified under HS code 4411.92, which pertains to fiberboard of wood or other ligneous materials. Chapter 44 covers wood and wood articles. Heading 4411 is specifically for fiberboard, which is produced from wood fibers bonded with resin or other organic substances under heat and pressure. The subheading 4411.92 is reserved for fiberboard with a density exceeding 0.8 g/cm³ that does not qualify as Medium Density Fiberboard (MDF). Hardboard is typically produced using a "wet process," which leaves a characteristic mesh pattern on one side, although "dry process" high-density fiberboard (HDF) also falls under this category if the density threshold is met. The classification is determined by the density and the extent of mechanical working. To fall under 4411.92, the board must not have been mechanically worked beyond simple surfacing or edge-working. If the board is further processed (e.g., perforated, tongued, or grooved), it may still fall under 4411, but the specific subheading depends on the density. Hardboard is widely used in the construction and furniture industries for floor underlayment, wall paneling, and drawer bottoms due to its high strength and smooth surface.

Common Misclassification

Hardboard is frequently misclassified as MDF under subheadings 4411.12, 4411.13, or 4411.14. The primary difference is density; MDF typically has a density between 0.5 and 0.8 g/cm³, whereas hardboard must exceed 0.8 g/cm³. It is also sometimes confused with particle board (4410), which is made from wood chips rather than refined fibers. Another common error is classification under 4412 (plywood), but hardboard lacks the layered veneer construction of plywood. Importers must provide density specifications to ensure correct classification under the 4411.92 subheading.

FAQ

What is the HS code for Hardboard?

The HS code for hardboard with a density exceeding 0.8 g/cm³ is 4411.92.

Is pegboard classified as hardboard?

Yes, if the pegboard is made from high-density fiberboard, it is classified under heading 4411, though its specific subheading may change if it is considered "worked" beyond simple surfacing.
