Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If considered ceramic articles of fused quartz
Alternative chapter for high-temp ceramic-like fused quartz crucibles, but tubes stay glass.
If fabricated into lab articles for semiconductor testing
Finished lab glassware from tubes shifts heading.
If in continuous crude form before cutting to 120mm
Cullet or continuous rods/tubes classify in 7001 as unworked crude glass.

Import Tips & Compliance
• Require supplier certificates of analysis for <1ppm impurities to support high-tech valuation
• ITAR/EAR checks for semiconductor end-use; declare as unworked to avoid dual-use restrictions
