AISI 321 Stainless Steel Round Bar from Canada

A round bar made from AISI 321 austenitic stainless steel containing approximately 10-12% nickel by weight, with a diameter of 25 mm (under 152.4 mm cross-section). This falls under HTS 7222.30.00.24 as other bars and rods of stainless steel with 8-24% nickel content and max cross-sectional dimension less than 152.4 mm. Commonly used in high-temperature exhaust systems due to its stabilized composition.

Import Tips

Provide mill test certificates confirming nickel content between 8-24% by weight and exact cross-sectional dimensions under 152.4 mm

Ensure chemical composition documentation matches AISI 321 specs to avoid reclassification to other nickel ranges

Watch for 'further worked' treatments like polishing, which may shift to higher subheadings if beyond basic hot-rolled state
