Last updated: August 2026 dataOriented strand board — a structural panel engineered from compressed wood strands bonded with resin — is a primary sheathing material for residential and commercial construction in the US. Canada is by far the dominant supplier, with Latvia, Romania, Poland, and the Czech Republic representing a growing European source base. The two US tariff lines cover unworked or minimally processed OSB and waferboard (4410120010) and further-worked or surfaced panels (4410120020). OSB imports from Canada may be subject to softwood lumber trade remedy considerations depending on scope determinations, and importers should monitor any applicable antidumping or countervailing duty orders.

Potentially. The scope of softwood lumber trade remedy orders has historically been subject to scope rulings, and certain engineered wood panels may be examined for inclusion depending on their wood species composition and manufacturing process. Importers of Canadian OSB should seek a scope ruling from the Department of Commerce or consult a licensed customs broker if there is any uncertainty about whether a specific product is covered.
Both OSB and waferboard are classified under heading 441012, but they differ structurally: OSB uses oriented, layered strands for directional strength, while waferboard uses randomly arranged flat wood wafers. For US tariff purposes, both fall within the same two 10-digit lines (4410120010 and 4410120020), with the distinction between lines based on the degree of further working or surface treatment rather than the OSB-versus-waferboard distinction.
