Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If floor joist components predominate and marketed primarily as flooring
Assembled flooring panels take precedence over roof truss function per heading structure.
If for non-truss builders' joinery like roof purlins or beams
General 'other' carpentry excludes specific roof trusses; purlins classify elsewhere.
If dark red meranti wood species is primary material
Specific tropical wood species have separate statistical suffixes from general coniferous trusses.

Import Tips & Compliance
• Provide architectural drawings showing truss-floor integration to avoid reclassification as separate flooring panels under 4418.65
• Ensure metal gang plates are listed separately from wood value to comply with softwood lumber duties
• Label shipments clearly as 'roof trusses' with model specs to prevent CBP disassembly for measurement
