Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If stainless steel composition
Stainless bars/rods (>10.5% Cr with low C) go to Chapter 72 stainless headings 7222-7223.
If ground or machined surfaces
Grinding/centerless finishing constitutes 'further worked' per Chapter notes, separate from cold-finished.
If chipper knife steel per note (f)
Specific chipper knife alloy steels have dedicated codes before general tool steel categories.

Import Tips & Compliance
• D2 qualifies as tool steel (>10.5% Cr, >1.2% C); critical cert needed vs general stainless
• Surface must show cold-finished matte appearance, no bright polish or Chapter note 'further worked' treatments
• Declare intended use optional but helpful; tool steel often scrutinized for correct heading
