Forged Alloy Steel Helical Gear Blank from China
Forged from high-strength alloy steel (e.g., 4340), this blank is pre-formed for helical gear production in heavy-duty speed changers and industrial transmissions. Classified under HTS 8483.90.50.10 due to its forged state and specific gearing application before hobbing or grinding. Ideal for angled tooth designs in high-speed machinery.

Import Tips
• Obtain alloy composition certificate; alloy steel content affects duty rates and requires precise HTS verification
• Label as 'gear blank for speed changer' with heat treatment details to prevent misclassification as plain shaft bearings
