Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If already incorporated into glass frit or powder
Glass in powder/flake form for pigments falls under Chapter 32, per exclusions in Chapter 28 notes.
If doped for electronic applications in rod form
Chapter notes allow doped nonmetals like selenium in unworked forms to stay in Chapter 28, but specifics shift.
If reduced to elemental selenium
Pure selenium metal classifies under 2804, not oxides; reduction process changes heading.

Import Tips & Compliance
• Obtain supplier's assay report confirming SeO2 content; industrial grades may face EPA import notifications under TSCA
• Use DOT-approved drums for transport; label as 'poison inhalation hazard' due to selenium toxicity
