Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in the form of rare-earth compounds containing tellurium
Compounds of rare-earth metals including tellurium derivatives fall under 2846, not pure element.
If converted to sodium tellurite
Sulfides and polysulfides of nonmetals like tellurium compounds shift to heading 2830.
If already alloyed into ferro-tellurium for steel
Alloyed forms like ferro-tellurium are classified as iron alloys in Chapter 72.

Import Tips & Compliance
• Use inert atmosphere packaging to prevent oxidation; oxidized powder may be questioned as oxide compound
• Comply with TSCA import requirements by pre-registering tellurium as a chemical substance
• Avoid declaring as 'metal powder' – specify 'nonmetal elemental tellurium' to match HTS description
