Wood, coniferous species, in the rough, whether or not stripped of bark or sapwood, or roughly squared, treated with paint, stains, creosote or other preservatives.

Classification of treated coniferous logs under HS 4403.11

Treated coniferous logs are classified under HS code 4403.11. This classification falls under Chapter 44, which covers wood and articles of wood. Heading 4403 is specifically for wood in the rough, whether or not stripped of bark or sapwood, or roughly squared. The subheading 4403.11 is designated for coniferous wood that has been treated with paint, stains, creosote, or other preservatives to prevent decay or insect infestation. The term "in the rough" is vital; it means the wood has not yet been sawn into planks or further manufactured. The treatment process, such as pressure-treating with chemicals like Chromated Copper Arsenate (CCA) or creosote, is the defining characteristic that separates this code from untreated logs. This classification ensures that the raw material is tracked based on its biological origin (coniferous) and its chemical treatment status.

Codes often confused with 4403.11

Common mistake. Treated coniferous logs are often misclassified under 4403.21, which is the code for untreated coniferous logs. The presence of any preservative treatment, even if not visible to the naked eye, necessitates the use of 4403.11. Another common error is classifying these logs under 4407 if they have been sawn lengthwise or sliced. Heading 4407 is for wood that has been further processed into lumber. Additionally, if the logs are specifically shaped for use as railway sleepers, they should be moved to heading 4406. Importers must distinguish between "roughly squared" (4403) and "sawn" (4407) to avoid customs delays.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. 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).
