Import Tips

Verify coniferous species origin with Certificates of Origin to confirm classification under 4409.10 and avoid reclassification to tropical hardwoods

Ensure shaping (tongue/groove) is along edges/faces and wood is unassembled; assembled panels shift to Chapter 44 headings like 4418

Provide detailed dimension specs and photos in entry docs to distinguish from simple planed lumber under 4407
