HS Code 4403.12 – Wood; non-coniferous species, in the rough, whether or not stripped of bark or sapwood, or roughly squared; treated with paint, stains, creosote or other preservatives
HS code 4403.12 is the 6-digit subheading for wood, non-coniferous species, in the rough, whether or not stripped of bark or sapwood, or roughly squared, treated with paint, stains, creosote or other preservatives. It is used for treated hardwood railway sleepers, preservative-treated tropical logs, treated oak pilings, treated eucalyptus poles and treated teak logs.
What HS 4403.12 covers
This HS code covers non-coniferous wood in the rough (logs), whether or not stripped of bark or sapwood, or roughly squared, that has been treated with preservatives such as paint, stains, or creosote. The treatment process significantly extends the lifespan of the timber by protecting it from decay, insects, and moisture, making it ideal for demanding outdoor and structural applications. In international trade, these treated hardwood logs are utilized for heavy construction, specialized railway sleepers, marine structures, and durable outdoor furniture components. Exporters often come from regions rich in hardwood forests and advanced timber treatment capabilities, including parts of South America, Africa, and Southeast Asia. Importers are typically construction companies, infrastructure developers, and manufacturers of high-durability wood products. Adherence to stringent regulations like the EUDR and EUTR is critical, requiring comprehensive due diligence to ensure the timber's legal and sustainable provenance, thereby combating illegal logging and deforestation.

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).
