Classification of oak lumber under HS 4407.91
Oak lumber is classified under HS code 4407.91. This code falls under Chapter 44, which encompasses wood and wood products. Heading 4407 is specifically reserved for wood that has been sawn or chipped lengthwise, sliced, or peeled, and it carries a mandatory technical requirement: the wood must be thicker than 6mm. The subheading 4407.91 is dedicated exclusively to the Quercus (oak) species. This classification allows for various levels of surface finishing; the lumber can be planed to create a smooth surface, sanded to a fine finish, or finger-jointed to create longer lengths from shorter pieces. Despite these processes, the material remains classified as lumber rather than a finished article of wood. This distinction is vital because once the wood is shaped into a specific profile, such as a decorative molding or a tongue-and-groove floorboard, it moves to heading 4409. The 4407.91 code is used by customs authorities to track the trade of hardwood timber and to apply relevant tariffs or anti-dumping duties that may exist for specific oak-producing regions. Accurate botanical identification is necessary to ensure the wood is not misclassified as another hardwood species like beech or maple.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
