Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If parts of liquid analysis instruments
HPLC column tubes as integral parts under Chapter 90 for lab apparatus.
If with Swagelok-style fittings
Tube assemblies with connectors become fittings under 7307.
If drawn and polished like grill/woven products, but rare
Highly finished small tubes might be seen as cloth pins/safety pins, unlikely.

Import Tips & Compliance
• Include surface finish specs (e.g
• electropolished); certify for cleanroom use
• Common error: classifying coiled as 'hose' instead of tube
