Doped Luminescent ZnS Powder 99.99% Base Purity from China
Zinc sulfide luminescent grade powder (99.99% ZnS purity) lightly doped for specific emission wavelengths in displays. Still classifiable under HTS 2830.90.1000 if dopant levels keep it chemically defined as primary zinc sulfide. Minimal doping doesn't alter base classification.

Import Tips
• Disclose dopant percentage (<1%) to avoid Chapter 38 reclass; provide emission spectrum data
• Test for homogeneity in samples
