Import Tips & Compliance
• Include material safety data sheets (MSDS) for chemical resistance verification, crucial for lab import compliance
• Document as 'glass closures for vials' separately from vials to stay in 7010.20, avoiding 7017 lab glassware
• Avoid mislabeling as 'lab equipment' which could trigger 9027 classification for scientific instruments
