AISI 9310 Gear Alloy Steel Sheet from Japan
AISI 9310 triple-alloy steel sheet, normalized, 500 mm wide and 1.8 mm thick, for precision gears. It is a flat-rolled product of other alloy steel (nickel-chromium-molybdenum) with a width under 600 mm. Normalizing is a heat treatment not considered further working, so it falls under tariff item 7226.99.00 as 'Other' flat-rolled products of other alloy steel.

Import Tips
• Ensure the sheet's width is under 600 mm and thickness is less than 4.75 mm, with width at least 10 times thickness
• Provide a mill certificate showing Ni, Cr, Mo content to classify as other alloy steel
• Note that normalizing is not considered further working for tariff purposes, but document the heat treatment process for CBSA
