Softwood plywood and softwood lumber are classified under different tariff headings, and trade-remedy orders are product-specific. While Canada faces countervailing and antidumping duties on softwood lumber, plywood from Canada is assessed separately. Importers should check current CBP and Commerce Department scope determinations to confirm whether specific plywood products are covered by any active orders.

US buyers typically specify panels meeting APA (Engineered Wood Association) performance standards or equivalent national standards, covering veneer grade, bond type (interior vs. exterior/exposure), and span rating. Imported panels not certified to recognized standards may face rejection by contractors or building inspectors, so mill certification documentation is a practical procurement requirement.
