Fused Quartz Semiconductor Processing Tubes from Germany
Fused quartz semiconductor processing tubes are long, unworked tubes used in diffusion furnaces and CVD reactors. Their extreme purity prevents contamination during high-temperature wafer processing. These tubes are classified under 7002.31.00 as unworked tubes of fused quartz.

Import Tips
• Verify that the tubes have not undergone any working processes such as grinding or polishing, as this would change classification
• Provide a certificate of analysis confirming fused quartz composition
• Check if the tubes are part of a larger semiconductor manufacturing system, which may affect classification
