AISI 4140 is a chromium-molybdenum alloy steel billet used for forging shafts and gears, supplied in semi-finished round form with diameters typically 100-300mm. It falls under HTS 7224.90.00 as a semi-finished product of other alloy steel (not stainless), distinct from stainless in chapter 7221 or high-strength/specialty steels defined in notes. These primary forms require further hot working like rolling or forging.

Import Tips
• Provide mill test certificates verifying alloy composition (e.g
• Cr 0.8-1.1%, Mo 0.15-0.25%) to confirm 'other alloy steel' status; ensure no further working like polishing per chapter note
• Common pitfall: incorrect declaration as stainless steel leading to chapter 7221 duties
