Products classified under HTS 4406.91.00.00
Pressure-Treated Pine Railway Sleepers
These coniferous wood sleepers made from pine are pressure-treated with preservatives to resist rot and insects, used as cross-ties in railway tracks. They fall under HTS 4406.91.00.00 as 'other' coniferous railway sleepers, distinct from non-coniferous types. The treatment enhances durability for heavy-duty rail applications.
Creosoted Douglas Fir Railroad Cross-Ties
Heavy-duty cross-ties from Douglas fir, a coniferous species, treated with creosote for long-term protection against decay in railroad applications. Classified under HTS 4406.91.00.00 for coniferous railway sleepers not of tropical wood. Standard dimensions support track stability under train loads.
Untreated Hemlock Tramway Sleepers
Coniferous hemlock wood sleepers designed for light rail or tramway tracks, supplied untreated for on-site processing. HTS 4406.91.00.00 covers these as 'other' coniferous railway or tramway sleepers. Suitable for urban transit systems requiring precise track alignment.
SYP Southern Yellow Pine Railroad Ties
Southern yellow pine (SYP) coniferous sleepers, kiln-dried and ready for rail installation, providing structural support for standard gauge tracks. Falls under HTS 4406.91.00.00 as coniferous railway sleepers. High strength-to-weight ratio ideal for mainline railroads.
CCA-Treated Spruce Railway Cross-Ties
Chromated copper arsenate (CCA) treated spruce sleepers from coniferous wood, engineered for North American rail networks. HTS 4406.91.00.00 applies to these 'other' coniferous sleepers. Treatment ensures 25+ year service life in harsh environments.
Laminated Hem-Fir Railroad Sleepers
Engineered laminated sleepers from hem-fir (mixed hemlock and fir) coniferous veneers, offering superior stability over solid wood. Classified under HTS 4406.91.00.00 for coniferous railway sleepers despite lamination. Used in high-speed rail demanding precision.
New Zealand Radiata Pine Tram Ties
Radiata pine coniferous sleepers from New Zealand plantations, optimized for urban tram systems with lighter load requirements. HTS 4406.91.00.00 covers these coniferous 'other' railway sleepers. Fast-growing sustainable source reduces import carbon footprint.
ACQ-Treated Lodgepole Pine Cross-Ties
