Zinc Sulfide Phosphor Powder
Fine powder of zinc sulfide doped with activators like copper or manganese, used as a green or blue-emitting luminophore in glow-in-the-dark paints and coatings. Classified under HTS 3206.50.00.00 as an inorganic product specifically designed for luminescence applications, fitting the chapter's scope for luminophores whether chemically defined or not.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If undoped and sold as general sulfide without luminophore activation
Plain zinc sulfide without luminescent activators is classified as sulfides in Chapter 28, not as specialized luminophores.
If used primarily as a coloring pigment rather than for luminescence
Chapter notes exclude pigments not emphasizing luminophore properties; shifts to other inorganic coloring matter.
If dispersed in a binder or medium for direct paint application
Preparations based on luminophores but formulated as finished paint ingredients fall under Chapter 38 mixtures.

Import Tips & Compliance
• Verify chemical purity and activator content via lab analysis to confirm luminophore function and avoid reclassification as general inorganic chemicals under Chapter 28
• Provide Safety Data Sheets (SDS) and emission spectra documentation to customs for proof of use as luminophores
• Avoid common pitfalls like mislabeling as 'pigment' without specifying phosphor properties, which could shift to heading 3206 other subheadings
