Import Tips
• Include ACS certificate of analysis; lab-grade status helps distinguish from industrial grades under same HTS
• For research imports <25kg, leverage HTS 9810.00.6000 duty-free but still requires 2926.90.50.10 declaration
• Avoid glass ampoules >100ml; may be viewed as retail packing shifting to Chapter 38
