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
