Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If fabricated into hollow drill rods
Hollow drill bars/rod have separate provisions earlier in 7228 heading
If high-speed tool steel instead
High-speed steel excluded from this subheading per hierarchy
If further worked with polishing
Any polishing or coating constitutes 'further worked' per Chapter note, moving to 7228.60

Import Tips & Compliance
• Declare exact processing method (hot-extruded vs hot-drawn) accurately; include chemical analysis report matching ball-bearing steel definition; segregate from universal mill plate dimensions to avoid 7211 classification
