Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If kaolin-rich variety
Bauxite-kaolin blends used as clays fall under Chapter 25, based on mineral dominance.
If in concentrate form
Washed/screened to higher concentration shifts to the calcine or concentrate subheading.
If from municipal waste incineration
Chapter 2620 note excludes such ash; goes to 2621 regardless of aluminum content.

Import Tips & Compliance
• Brazilian ore often requires phytosanitary certificates due to organic traces; common pitfall for US ports
• Report gross weight and moisture-adjusted assay per statistical notes to prevent valuation disputes
• Comply with Lacey Act declarations for tropical ore imports to avoid seizures
