Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-assembled into complete chromatography fittings
Finished lab instruments or parts classify under Chapter 90, not raw material tubes.
If other stainless alloys not meeting Ni/Mo specs
Base stainless without elevated Ni/Mo falls into 7306.50 rathern than 7306.40.10.

Import Tips & Compliance
• Include cleanroom certification if for pharma; affects FDA but not HTS directly
• Measure OD/ID precisely—capillary sizes (<3mm) scrutinized for wire vs tube debate
