Product classification
HS code for Oriented strand board: 4410.12
Oriented strand board (OSB) of wood, whether or not agglomerated with resins or other organic binding substances.
Classification of oriented strand board under HS 4410.12
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.

Codes often confused with 4410.12
Common mistake. 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.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
