Import Tips

• Verify chemical purity via certificate of analysis (COA) to confirm classification as chemically defined zinc sulfide per Chapter 28/29 notes

• Include Safety Data Sheet (SDS) showing non-radioactive, non-toxic handling; avoid misclassification as pigments (3206)

• Declare exact CAS number (1314-98-3) on entry to prevent scrutiny as organo-inorganic compounds excluded by Chapter 28 Note 2
