AISI 439 Stainless Steel Sheet from Canada
Flat-rolled stainless steel sheet conforming to AISI 439 grade with approximately 17% chromium but certified as containing less than 15% by weight overall due to specific alloy composition, width over 600 mm, used in automotive exhaust systems. This falls under HTS 7219.90.00.60 as flat-rolled stainless steel products, not cold-rolled, of width 600 mm or more, other, containing less than 15% chromium. It meets Chapter 72 definitions for stainless steel despite chromium content nuance.

• Ensure width measurement exceeds 600 mm at entry; 3
• Avoid classifying as heat-resisting steel (note g) without exact composition match
