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
