Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If heat-resisting steel composition
Low carbon <0.3% with 4-10.5% Cr per note (g) shifts to heat-resisting steel subheading.
If imported as complete chipper machine part
Finished chipper knives classify under machinery Chapter 84, not raw steel bars.
If high-strength steel per note (a)
Minimum yield specs qualify for high-strength alloy bars in 7225.
