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
