Refined Tellurium Metal Ingots from China
High-purity tellurium ingots, typically 99.99% pure, used in the production of semiconductors and alloys. This elemental form of tellurium, a nonmetal in Chapter 28, is classified under HTS 2804.50.0020 as uncompounded tellurium metal.

Import Tips
• 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
