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
