Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If qualifying as ball-bearing steel powder
Chapter 72 note (h) defines specific alloy composition for ball-bearing steel, shifting to Chapter 72 alloy powder heading
If stainless steel composition
Stainless powders containing 4%+ chromium fall under specific stainless steel powder subheading
If chemically treated for specific end-use or mixed with binders
Surface treatments beyond Chapter 72 'further worked' definition or chemical preparations move to chemical preparations heading

Import Tips & Compliance
• Provide mill test reports confirming non-alloy status per Chapter 72 note (e),Declare average particle size and production method (atomized vs. reduced) for CBP verification,Avoid classifying as 'further worked' if surface treated beyond basic passivation
