Nitrided Ferrochromium 68% Cr from Canada
Nitrogen-bearing ferrochromium with 68% Cr, up to 0.2% N, and moderate carbon, used for nitrogen-alloyed stainless steels. Falls under HTS 7202.49.50 as other ferrochromium; nitrogen content doesn't alter base ferroalloy classification. Improves steel strength and corrosion resistance.

Import Tips
• Document nitrogen analysis method (e.g
• inert gas fusion) as CBP may verify special alloy claims
• Check for country-specific quotas; nitrided grades often from India or Zimbabwe
• Avoid bulk bagging without liners—moisture absorption affects nitrogen stability
