Import Tips

Verify structural engineering certifications and load-bearing specifications meet US building codes like IBC for smooth customs clearance

Include detailed assembly diagrams and metal connector invoices to prove classification as complete roof trusses rather than loose lumber

Watch for anti-dumping duties on softwood lumber components; maintain records separating truss value from raw wood
