7227.90.60Same rate: 35%

If ball-bearing steel per note (h)

Specific composition matching ball-bearing steel note (h) (0.95-1.13% C, 1.25-1.65% Cr) goes to 7227.90.6030.

7213.91Lower: 10% vs 35%

If for non-tool alloy steel

Fails tool steel definitions in note (e); treated as circular cross-section alloy steel bars/rods.

7228.30.80Same rate: 35%

If sold as straightened bars, not coils

Heading 7228 covers hot-rolled products not in coils, even if same tool steel composition.

Import Tips & Compliance

Submit detailed alloy analysis reports confirming note (e)(iii) criteria to CBP upon entry

Label coils clearly as 'tool steel' with grade; mislabeling can lead to 7213 reclassification

Check for any further working (e.g

polishing) which excludes from hot-rolled heading per chapter notes
