HS Code 4406.92 – Wood; railway or tramway sleepers (cross-ties), impregnated, non-coniferous
HS code 4406.92 is the 6-digit subheading for wood, railway or tramway sleepers (cross-ties), impregnated, non-coniferous. It is used for impregnated hardwood railway sleepers, treated non-coniferous cross-ties, preserved timber track supports, tropical hardwood railway ties and oak railway sleepers.
What HS 4406.92 covers
This code encompasses non-coniferous wooden railway sleepers, also known as cross-ties, that have undergone impregnation treatment. These heavy-duty timber products are crucial components in railway infrastructure globally, providing support for rails and maintaining track gauge. Impregnation, typically with creosote or other preservatives, significantly extends their lifespan by protecting against rot, insects, and weathering, making them suitable for demanding outdoor environments. Major importers include countries with extensive rail networks undergoing maintenance or expansion, such as those in Europe, North America, and parts of Asia. Exporters often come from regions with abundant hardwood resources and established timber processing industries, like certain South American or Southeast Asian nations, as well as Eastern Europe. Key considerations in this trade involve the durability and treatment standards of the wood, environmental regulations regarding preservative chemicals, and the logistical challenges of transporting heavy timber. The demand is closely tied to government infrastructure spending and railway modernization projects.

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).
