Synthetic Brookite Titanium Concentrate from China
Brookite, a less common TiO2 polymorph, appears in some natural concentrates but often synthetic for research. However, natural concentrates fall under HTS 2614.00.60 as other titanium ores. Used in advanced photocatalysts and optics.

Import Tips
• Polymorph identification via XRD required to distinguish from anatase/rutile forms
• If lab-synthesized, reclassify under Chapter 28; natural origin certificates essential
• Small shipment exemptions may apply for research quantities under de minimis rules
