HS Code for Oriented strand board

Oriented Strand Board (OSB) is classified under HS code 4410.12. This classification is based on the manufacturing process where wood strands are arranged in specific orientations and bonded together with resins under heat and pressure. Chapter 44 of the Harmonized System covers wood and articles of wood, and heading 4410 specifically addresses particle board and similar board of wood or other ligneous materials. OSB is distinguished from standard particle board by the size and orientation of the wood flakes, which provide enhanced structural integrity suitable for load-bearing applications in construction. The classification 4410.12 is specific to OSB, ensuring that it is not confused with other engineered wood products like fiberboard or plywood. The resins used are typically organic binding substances, and the presence of these additives does not exclude the product from this heading, provided the product retains the essential character of wood board. The strands are usually layered cross-wise to improve mechanical properties, a feature that defines the product under the 4410.12 subheading.

Products Included

• Structural OSB panels
• OSB sheathing for roofing and walls
• Resin-bonded wood strand boards
• OSB subflooring
• Oriented strand lumber (OSL) in board form

Common Misclassification

OSB is often confused with fiberboard, which is classified under heading 4411. Fiberboard is made from wood fibers rather than distinct strands or flakes. It is also frequently misclassified as plywood under heading 4412; however, plywood consists of thin sheets of veneer glued together, whereas OSB is composed of compressed strands. Misclassification also occurs with standard particle board (4410.11), which lacks the oriented strand structure.

FAQ

What is the HS code for oriented strand board?

The specific HS code for oriented strand board (OSB) made of wood is 4410.12.

How does OSB differ from particle board in classification?

While both are under heading 4410, OSB (4410.12) is made of large, oriented strands, whereas particle board (4410.11) is made of smaller, randomly distributed wood particles or chips.
