Import Tips
• Confirm the hydration level and chemical formula, as the product may be considered a hydroxide; both are covered by heading 28.25
• Provide a certificate of analysis to show it is not a mixture with other metal oxides
• If the product is dried to an anhydrous form before import, the classification remains the same
