Baddeleyite Ore Concentrate from China
Baddeleyite is a rare zirconium dioxide (ZrO2) mineral ore, concentrated from Brazilian deposits through gravity separation. Classified under HTS 2615.10.00.00 as zirconium ore, it serves as a key feedstock for zirconia production in refractories and advanced ceramics. The concentrate typically assays over 60% ZrO2.

Import Tips
• Require independent lab assays for ZrO2 content to avoid reclassification as metal oxide; ensure proper hazardous material declarations if silica dust present
• Pitfall: confusing with synthetic zirconia under Chapter 28
