This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of stainless steel rather than other alloy
Stainless steel variants shift to 7304.39, while other alloys like Incoloy remain in 7304.59 based on composition.
If for use solely in nuclear reactors
Tubes designed exclusively for nuclear heat transfer classify under nuclear reactor parts, not general boiler tubes.
If hollow bars over 16mm dimension
If cross-sectional dimension exceeds 16mm and functions more as hollow bar than tube, it moves to Chapter 72.

Import Tips & Compliance
• Include hydrostatic test certificates proving pressure suitability for superheaters or condensers
• Label with exact alloy grade (e.g
• Incoloy 800H) to avoid reclassification to carbon steel tubes
