Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If austenitic stainless steel per common definitions
Certain stainless alloys with stable austenitic structure at room temp classify under 7222, not generic other alloys.
If non-round cross-section (e.g., flat or shaped)
7229.90.10 covers other than round wire; round specifically directed to .50 subheading.
If imported as part of compressor assembly
End-use as machinery part may classify under Chapter 84 functional heading, principal use rule.

Import Tips & Compliance
• Submit chemical analysis certificate confirming 17% Cr, 7% Ni composition to avoid stainless steel misclassification
• Measure and document exact diameter; tolerances must confirm <1.0 mm for this subheading
• Label as 'drawn wire, not further worked' to prevent inspection disputes
