Import Tips
• Document bamboo lamination process and scale precision to distinguish from decorative wooden articles
• Collector's items require origin certificates; HTS classification unaffected by age but affects valuation
• Avoid classifying with protective cases; separate leather/metal cases go to Chapter 42
