Import Tips
• 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
