Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the tubing is made of fused quartz or other fused silica
Fused silica glass tubes are classified separately under this heading, not under 'other' tubes.
If the tubing is cut to length and polished for direct laboratory use
Laboratory glassware of fused quartz or other low-expansion glass falls under heading 70.17.
