Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If selenium instead of tellurium
Other nonmetals like selenium have separate subheading 2804.90 within same heading.
If semiconductor components manufactured from the rods
Finished semiconductor devices shift to Chapter 85 photosensitive articles.
If used in semiconductor manufacturing equipment parts
Parts for semiconductor machines fall under 8486, not raw elemental materials.

Import Tips & Compliance
• Provide zone-refined purity documentation; standard refining insufficient for 6N claims
• For research quantities, use 'samples' valuation but still classify under 2804.50.0020
• Prevent misclassification as selenium (2804.90) by including atomic spectroscopy data
