Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If powder metal bar is cold-drawn or extruded
Any cold-forming operation, even on PM material, shifts to cold-formed subheading.
If semi-finished alloy steel before hot-rolling
Unwrought or semi-finished forms prior to bar production classified in 7224.

Import Tips & Compliance
• PM process documentation required but classification follows chemical composition, not production method
• Distinguish from extruded (cold-formed) PM rods which go to 7228.30.0010
• Ensure no cladding or coating; such 'further worked' treatments per chapter note change heading
