Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If doped for electronics and cut into discs or wafers
Doped chemical elements cut into wafers fall under 3818 per Chapter 28 note, not pure elemental tellurium.
If in the form of inorganic tellurium salts
Inorganic salts of nonmetals like tellurium salts are classified in 2842, excluding pure elemental form.
If processed into semiconductor devices
Finished electrical articles containing tellurium, like diodes, move to Chapter 85 electrical machinery.

Import Tips & Compliance
• Provide mill test certificates confirming 99.99% purity to verify elemental tellurium classification and avoid reclassification as alloys
• Declare exact purity levels and intended use (e.g
• semiconductor doping) on commercial invoice to comply with Chapter 28 notes
• Ensure packaging prevents oxidation; common pitfall is misdeclaring as compound, leading to higher duties under 2842
