Import Tips
• Ensure the product is clearly labelled as magnesium aluminosilicate for pharmaceutical use; the CBSA may request a certificate of analysis
• If imported as a finished antacid preparation, it may fall under Chapter 30 instead—verify with a ruling
• Keep records of the chemical composition to support classification under 2842.90.00
