More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If concrete reinforcing bars/rods with ribs/grooves
Deformed hot-rolled products for concrete reinforcement classify under non-alloy 7214 per U.S. note (c), regardless of minor alloying.
If in straight lengths, not coils
Hot-rolled alloy steel bars/rods not in irregularly wound coils fall into the straight-length 'other' category.
If further worked with indentations/ribs for concrete use
Post-rolling deformations like ribs produced during rolling shift to reinforcing bars under Chapter 73 tubes/pipes.

Import Tips & Compliance
• Submit chemical analysis reports verifying elements like nickel (0.4-0.7%), chromium (0.4-0.7%) to confirm alloy status and avoid plain steel headings
• Check for minimum yield strength if claiming high-strength steel concessions; document hot-rolling process to prevent cold-rolled mix-up
