Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If true heat-resisting steel per note (g)
Specific low-carbon/high-Cr alloys meeting note (g) get dedicated 7220.20 subheading.
If clad with other metal
Cladding counts as further working per chapter note, reclassifying to 7222.50.
If imported as heat exchanger parts
End-use as specific machinery parts may shift to chapter 84 under end-use rules.

Import Tips & Compliance
• Test certs must show titanium stabilization; distinguish from standard austenitics
• High-temp end-use doesn't change classification—based purely on composition/processing
• Prevent pre-entry rust; chapter note denies duty allowance for discoloration
