HS code for Oak logs: 4403.91
Wood, oak, in the rough, whether or not stripped of bark or sapwood, or roughly squared, untreated.
Classification of oak logs under HS 4403.91
Oak logs are classified under HS code 4403.91, which is situated within Chapter 44 of the Harmonized System. This chapter covers wood and articles of wood, while heading 4403 specifically addresses wood in the rough. To be accurately classified under this code, the wood must be of the Quercus species (oak) and remain in its natural, felled state. The classification includes logs that have had their bark or sapwood removed, as well as those that have been roughly squared. Roughly squared wood refers to logs that have had their rounded sides removed with an axe or saw to create a preliminary rectangular shape for easier transport, but which have not yet been sawn into lumber. A critical requirement for 4403.91 is that the wood must be untreated. If the logs have been painted, stained, or treated with creosote or other preservatives to prevent decay or insect infestation, they would typically be reclassified under subheading 4403.11. This code is essential for international trade monitoring, as oak is a high-value hardwood subject to various environmental and forestry regulations, including the Lacey Act in the United States and similar timber legality frameworks globally.

Codes often confused with 4403.91
Common mistake. The most frequent misclassification occurs with HS code 4407.91, which covers oak lumber that has been sawn or chipped lengthwise and is thicker than 6mm. Another common error involves HS code 4403.11, which is used if the oak logs have been treated with preservatives. Importers often confuse 'roughly squared' logs (4403) with 'sawn' timber (4407).

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).
