HS code for Untreated oak logs: 4403.91
Wood, oak, in the rough, whether or not stripped of bark or sapwood, or roughly squared, untreated.
Classification of untreated oak logs under HS 4403.91
Untreated oak logs are classified under HS code 4403.91 because they fall under the category of wood in the rough. According to the Harmonized System's General Rules of Interpretation, heading 4403 is dedicated to timber in its natural, felled state. The subheading 4403.91 specifically identifies wood of the genus Quercus (oak). For a product to remain in this classification, it must not have undergone significant processing beyond the removal of bark or sapwood, or rough squaring to facilitate transport. The term "untreated" is critical here; the wood must not be impregnated with creosote, paint, stains, or other chemical preservatives. If the logs were treated for long-term preservation, they would be classified under 4403.11. Furthermore, the logs must not be sawn or sliced into planks, as that would shift the classification to heading 4407. This code ensures that raw oak timber is distinguished from processed lumber and treated wood products for international trade and environmental monitoring purposes.

Codes often confused with 4403.91
Common mistake. A frequent error is confusing 4403.91 with HS code 4407.91. While both refer to oak, 4407.91 is for oak wood that has been sawn or chipped lengthwise, sliced, or peeled, and exceeds 6mm in thickness. Another common misclassification is 4403.11, which is reserved for oak logs that have been treated with paint, stains, or preservatives like creosote. Importers must also distinguish these from 4401.12, which covers non-coniferous fuel wood in logs, though fuel wood is typically of lower quality and shorter length.

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).
