Chromite Ore Lumps from Mexico
Chromite ore in lump form, primarily consisting of iron chromium oxide (FeCr2O4), used as the main source for chromium extraction in ferrochrome production. Classified under HTS 2610.00.00 as chromium ores and concentrates due to its high chromite content and direct use in metallurgical processes. Typical lump sizes exceed 6.35 mm after crushing from mined rock.

Import Tips
• Obtain assay certificates verifying chromium content (typically 40-50% Cr2O3) from accredited labs to confirm classification and avoid reclassification as lower-grade minerals
• Ensure proper declaration of moisture content and particle size distribution to comply with statistical reporting requirements and prevent customs valuation disputes
• Verify origin certificates as many chromite ores originate from South Africa or India; be aware of potential anti-dumping duties on specific sources
