Import Tips

• Verify purity and synthetic production documentation to confirm classification under 2811.22.10.00, distinguishing from natural diatomaceous earth

• Include Material Safety Data Sheets (MSDS) and certificates of analysis; check for cobalt chloride indicators which may trigger hazardous material rules

• Avoid misclassification as activated carbon (3802.10); test for silica content >99%
