Products classified under HTS 7225.99.00
AISI 4140 Alloy Steel Plate
A flat-rolled plate of chromium-molybdenum alloy steel (AISI 4140) with a width exceeding 600 mm, used in machinery and structural applications. Classified under HTS 7225.99.00 as 'other alloy steel' flat-rolled products not meeting specific alloy definitions in chapter notes like high-strength, tool, or ball-bearing steel. It is not further worked beyond basic rolling.
AISI 4340 Chromium-Molybdenum Steel Sheet
Flat-rolled sheet of AISI 4340 nickel-chromium-molybdenum alloy steel, width over 600 mm, commonly used in aerospace and automotive components. Falls under HTS 7225.99.00 as other alloy steel not specified in chapter notes for tool steel, ball-bearing steel, or heat-resisting alloys. Supplied in annealed condition without further surface treatments.
SAE 8620 Case-Hardening Alloy Steel Plate
Flat-rolled plate of SAE 8620 low-alloy steel with nickel, chromium, and molybdenum additions, width 600 mm or more, for carburizing applications in gears and shafts. HTS 7225.99.00 covers this as 'other' alloy steel flat products not matching chapter note definitions for specialized steels. Thickness typically 4-50 mm, not further worked.
AISI 4130 Chromoly Steel Sheet
Chromium-molybdenum alloy steel (AISI 4130) flat-rolled sheet over 600 mm wide, popular in aircraft tubing and racing frames. Classified in HTS 7225.99.00 for other alloy steel flat products not fitting precise chapter note alloys like chipper knife or razor blade steel. Delivered mill finish, not in coils.
EN24 Alloy Steel Heavy Plate
EN24 (40NiCrMo8) medium carbon alloy steel plate, flat-rolled with width >600 mm, thickness 20-100 mm for heavy machinery bases. HTS 7225.99.00 applies to such 'other' alloy flat-rolled products excluding those defined as universal mill plates or concrete reinforcing per notes. Not clad or coated.
AISI 8630 Alloy Steel Mill Sheet
Carburizing-grade AISI 8630 alloy steel flat-rolled sheet, 600+ mm width, for automotive transmission gears. Under HTS 7225.99.00 as other non-specialty alloy steel flat products, distinct from razor blade or chipper knife steels in chapter notes. Basic hot-rolled finish.
HY-80 High-Yield Alloy Steel Plate
HY-80 nickel-alloy steel plate for naval applications, flat-rolled >600 mm wide, offering high strength. HTS 7225.99.00 for other alloy steel flats not defined as high-strength (yield criteria not met) or tool steel in notes. Thickness 10-50 mm, plain surface.
15CrMo Alloy Steel Pressure Vessel Sheet
15CrMo low-alloy steel sheet for boiler/pressure vessel use, width over 600 mm per ASTM specs. Classifies in HTS 7225.99.00 as other alloy flat-rolled steel not matching heat-resisting or electrical steel definitions. Normalized condition, no coatings.
