Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

7224.90.00Same rate: 35%

If non-alloy steel composition

Lacks alloying elements required for Chapter 72 alloy steel headings; reverts to non-alloy free-cutting or other bars.

8431.49Lower: 10% vs 35%

If imported as completed drill rods/parts

Assembled or further worked into drill rods moves to Chapter 84 machinery parts, not raw Chapter 72 bars.

7228.50Same rate: 35%

If cross-section 80-228 mm diameter

Smaller diameter cold-finished alloy bars fall under the preceding size subheading 7228.50.30.

Import Tips & Compliance

Include heat analysis certificate proving 4340 alloy specs; U.S

Note (e) defines qualifying alloy elements

Document cold-forming process to distinguish from hot-rolled; inspect for surface scale which indicates hot-rolling

Large diameter bars may require special handling declarations for transportation and storage compliance
