High-Carbon Ferrochrome
High-carbon ferrochrome is a ferroalloy containing 50-70% chromium and 4-8% carbon, used primarily in stainless steel production. It falls under HTS 7202.49.50.90 as 'other ferrochromium' that is not low-carbon, not silico-ferrochromium, and not containing over 30% chromium by weight. This classification applies to standard grades produced via electric arc furnace smelting.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing by weight less than 4% carbon
Low-carbon ferrochromium is separately classified to distinguish from high-carbon grades used in different steelmaking processes.
If primarily ferro-silicon chromium with silicon over 3%
Silico-ferrochromium with higher silicon content falls under ferro-silicon chromium heading based on composition.
If chemically processed into master alloy with additives beyond basic ferrochrome
Prepared binders or chemical preparations for foundry use may shift from Chapter 72 ferroalloys to Chapter 38.

Import Tips & Compliance
• Verify chromium and carbon content via mill certificates to confirm classification under 'other ferrochromium' and avoid misclassification as low-carbon (7202.49.10)
• Ensure proper documentation of alloy composition per USITC Chapter 72 notes; test for compliance with high-strength steel exclusions if blended
