Products classified under HTS 7224.90.00.45
AISI 4140 Alloy Steel Rectangular Bloom
A rectangular cross-section semi-finished product made from AISI 4140 chromium-molybdenum alloy steel, with width less than four times the thickness, used for forging into shafts and gears. Classified under HTS 7224.90.0045 as other alloy steel semi-finished products of rectangular shape not meeting rectangular bar criteria. Meets alloy steel definition with added chromium and molybdenum beyond carbon steel limits.
17-4 PH Stainless Steel Square Billet
Precipitation hardening 17-4 PH stainless steel in square cross-section with side length <4x thickness (square), primary form for aerospace components. HTS 7224.90.0045 covers alloy steel semi-finished products where width doesn't reach 4x thickness threshold. Stainless steel qualifies as alloy steel under Chapter 72 definitions.
AISI 8620 Carburizing Steel Rectangular Slab
Low-alloy 8620 steel rectangular semi-finished product for case hardening applications, width controlled <4x thickness. Falls under 7224.90.0045 as other alloy steel primary forms not qualifying as bars. Nickel-chromium-molybdenum content defines alloy steel status.
Maraging Steel C250 Square Ingot
High-strength maraging C250 steel square section primary form for missile/rocket components, dimensions ensuring width <4x thickness. HTS 7224.90.0045 applies to such alloy steel semi-finished products. Ultra-high nickel content (18%) clearly alloy steel.
