HS Code 4403.11 – 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
HS code 4403.11 is the 6-digit subheading for 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. It is used for treated utility poles, creosoted railway sleepers, preservative-treated fence posts, treated marine pilings and treated landscaping timbers.
What HS 4403.11 covers
This HS code covers coniferous wood in the rough (logs), whether or not stripped of bark or sapwood, or roughly squared, that has been treated with preservatives like paint, stains, or creosote. This treatment is crucial for enhancing durability and resistance to pests, fungi, and rot, making the timber suitable for outdoor applications and harsh environments. In international trade, these treated logs are primarily used for utility poles, railway sleepers, marine pilings, and heavy construction. Exporters are typically countries with extensive coniferous forests and timber treatment facilities, such as Canada, the USA, and Nordic countries. Importers include infrastructure development companies, railway operators, and construction firms in regions requiring durable timber. Compliance with regulations like the EUDR and EUTR is paramount, as these demand rigorous verification of the timber's legal and sustainable origin to combat illegal logging and deforestation, impacting global supply chains.

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).
