Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If worked into bars/rods
After hot working into bars, classifies as stainless bars/rods in Chapter 72.
If pig iron or spiegeleisen
Lower alloy content would classify as cast pig iron, not stainless.
If universal mill plate dimensions
If meeting universal mill plate specs (width 150-1250mm, thick ≥4mm), separate subheading.

Import Tips & Compliance
• Provide heat analysis confirming 17% Cr and copper/niobium for PH grade verification
• Document as 'primary form' to avoid confusion with forged bars under 7222.30
• Inspect for surface rust; no allowances per Chapter 72 note on discoloration
