Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cold-rolled after hot-rolling
Cold-rolled tool steel (further worked) classified separately from hot-rolled.
If primarily carbon steel rather than alloy
Low alloy content may classify under flat-rolled carbon steel headings.
If for non-coil hot-rolled form
Tool steel hot-rolled plates/sheets not in coils go to thickness-based non-coil codes.

Import Tips & Compliance
• Declare exact chemical analysis matching US tool steel note; mismatches lead to 7225.99 reclassification
• Verify width exceeds 600 mm and coil packaging intact to qualify for this specific subheading
• Document hot-rolling only; any cold-rolling shifts to 7225.40 series
