Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If ball-bearing steel compositions per note (h)
Very specific C-Cr compositions for bearings have dedicated statistical breakout.
If supplied as ferro-alloy rather than finished steel
Ferroalloys remain in Chapter 72 heading 7206, not finished steel products.
If when processed into hollow drill pipe sections
End use and completion state shift to finished hollow products heading.

Import Tips & Compliance
• Certify Ni (3.5-4.5%), Cr (1.4-1.7%), Mo content via independent lab analysis
• Distinguish from castings by proving continuous casting process vs. sand molding
• Avoid duty increase by ensuring no 'further working' like artificial oxidation occurred
