Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of heat-resisting steel per note (g)
Low-carbon, high-chromium alloys for heat resistance classify separately from high-speed tool steels.
If stainless with specific razor blade dimensions
Narrow stainless flats meeting note (d) for razor blade steel go to Chapter 72 stainless headings.
If sold as a set with drill components
Sets including bars and shaped sections may classify under composite goods rules.

Import Tips & Compliance
• Certify cobalt and molybdenum content explicitly, as M42 exceeds standard high-speed thresholds
• Document production method (hot-rolled) to differentiate from cold-drawn which may alter classification
• Beware of rust/discoloration claims; no duty allowance per chapter note
