Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If after wafer processing into memory ICs
SiGe wafers become amplifiers in processors under IC headings.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Specify Ge content percentage (20-50%) critical for duty assessment
• Avoid valuation based on downstream IC price; use fab cost sheets
