Import Tips

Verify bamboo species origin and provide CITES documentation if applicable to ensure compliance with endangered species regulations

Include engineering certifications confirming pre-drilled/notched features for studs to avoid reclassification as basic sawn lumber

Check for moisture content labeling (typically under 19%) to meet building code standards and prevent mold issues during import
