Import Tips
• Include GC-MS analysis certificate verifying isoprene ≥98% and impurity profile for customs chemical verification
• Small package exemption may apply for lab quantities <1L but still requires UN2357 proper shipping name
• Avoid misclassification as Chapter 38 reagent preparation; remains Chapter 29 due to chemical purity dominance
