Import Tips
• Ensure the DDBSA is destined for the manufacture of slow dissolving inside toilet tank solids to qualify for this tariff item
• Keep documentation of the end-use, as CBSA may request proof
• Verify the product is not a separate chemically defined compound, which would be excluded from Chapter 34
