HS Code 4403.91 – Wood; oak, in the rough, whether or not stripped of bark or sapwood, or roughly squared, untreated
HS code 4403.91 is the 6-digit subheading for wood, oak, in the rough, whether or not stripped of bark or sapwood, or roughly squared, untreated. It is used for white oak logs, red oak timber, untreated oak billets, rough-sawn oak lumber and oak for barrel staves.
What HS 4403.91 covers
This category encompasses oak wood in its most basic form: logs or roughly squared timber, before significant processing, whether or not stripped of bark or sapwood, and untreated. Oak is highly prized globally for its exceptional strength, durability, and aesthetic appeal, making it a staple in high-quality furniture, flooring, cabinetry, and heavy construction. International trade involves the movement of these raw logs from temperate forested regions to sawmills and processing plants worldwide. Major importers are often countries with advanced woodworking industries but limited domestic oak resources, such as China, Vietnam, and various European nations. Exporters include countries with extensive oak forests like the USA, France, Germany, and Ukraine. Key aspects of trade include ensuring sustainable forestry practices, verifying the legality of harvesting, and adhering to timber legality regulations like the EU Deforestation Regulation (EUDR) and the EU Timber Regulation (EUTR), especially for European markets, to prevent illegal timber from entering the supply chain.

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).
