Raw Witherite Ore from China
Natural barium carbonate ore extracted from mineral deposits, typically in lump or crushed form, used as a raw material for barium compound production. Classified under HTS 2511.20.00.00 as unprocessed natural witherite, whether or not calcined but excluding barium oxide. It serves as the primary source for industrial barium chemicals.

Import Tips
• Verify purity through assay certificates to confirm natural barium carbonate content and avoid reclassification as synthetic under Chapter 28
• Provide geological origin documentation as proof of natural extraction to distinguish from precipitated barium carbonate
• Ensure proper labeling as 'natural witherite' to prevent customs disputes over calcination status
