Import Tips
• Distinguish from barium oxide by providing chemical analysis showing carbonate form (BaCO3 >95%) to avoid misclassification under 2816
• Label as 'ground' with particle size data to separate from crude witherite imports
• Check for calcination details in invoices, as excessive heat could risk reclassification if converted to oxide
