HS Code for OSB board

Oriented Strand Board (OSB) is classified under HS code 4410.12. This classification falls within Chapter 44, which covers wood and articles of wood. Heading 4410 specifically addresses particle board and similar boards of wood or other ligneous materials, whether or not agglomerated with resins or other organic binding substances. OSB is a structural engineered wood product made by layering strands (flakes) of wood in specific orientations, which are then bonded with waterproof adhesives under heat and pressure. The HS code 4410.12 was created to distinguish OSB from standard particle board (4410.11) due to its unique manufacturing process and superior structural properties. The classification applies to the board regardless of whether it has been sanded or further worked, such as being tongued and grooved for flooring applications. As long as the product retains the essential character of a board of wood strands, it remains under 4410.12, following General Interpretative Rule 1 and the specific subheadings of the 4410 group.

Common Misclassification

OSB is frequently misclassified under 4410.11, which is for standard particle board (chipboard). While both are made of wood particles, OSB uses larger strands oriented in layers. It is also sometimes confused with 4412 (Plywood), but plywood is made of thin veneers of wood, not strands. Another error is 4411, which covers fiberboard (like MDF or HDF), where the wood has been reduced to individual fibers rather than strands or chips.

FAQ

What is the HS code for OSB board?

The HS code for Oriented Strand Board (OSB) is 4410.12.

Is OSB classified differently if it is waterproof?

No, the use of waterproof resins or binders does not change the HS code; OSB remains 4410.12 regardless of the specific type of adhesive used in the bonding process.
