Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If stainless variant used
Some high-strength naval steels qualify as stainless under 7224.
If fabricated into tubes/pipes
Further manufacture into tubular products moves to Chapter 73.
If cold-drawn finish
Cold-forming processes reclassify from 7228.60 to 7228.30.

Import Tips & Compliance
• Military-spec products require ITAR/DFARS compliance beyond tariff classification
• Certify yield strength documentation, though not high-strength steel per note (a) thickness criteria
• Ensure no cladding/coatings, as further worked per chapter note shifts classification

AISI 4140 Alloy Steel Round Bar
A hot-rolled round bar made from AISI 4140 chromium-molybdenum alloy steel, commonly used for shafts, gears, and axles in machinery. It falls under HTS 7228.60.60.00 as a non-cold-formed bar of other alloy steel, not meeting specific alloy steel definitions in chapter notes like tool steel or ball-bearing steel. The product is supplied in straight lengths without cold-forming processes.
AISI 4340 Alloy Steel Flat Bar
Hot-rolled flat bar of AISI 4340 nickel-chromium-molybdenum alloy steel, ideal for structural components and aircraft parts. Classified under HTS 7228.60.60.00 as other bars of alloy steel that are not cold-formed and do not qualify as tool steel or other specified types. Delivered in rectangular cross-sections without further cold working.
17-4 PH Stainless Alloy Steel Round Bar
Precipitation-hardening 17-4 PH stainless alloy steel round bar, hot-rolled for aerospace fasteners and valves.
