Import Tips

• Provide chemical purity certificates (typically ≥98%) and CAS number (485-47-2) documentation to verify classification under Chapter 29

• Ensure proper Hazard Communication labeling as it’s a skin and eye irritant; include Safety Data Sheets (SDS) for customs clearance

• Avoid misclassification as a finished test kit—pure chemical only qualifies under this specific HTS code
