Import Tips
• Ensure the powder is free of organic matter and declare it as 'powder of shells' to match the tariff description
• If the powder is intended for agricultural use, check with the Canadian Food Inspection Agency (CFIA) for any fertilizer regulations
• Keep the grinding process simple (no heat or chemical treatment) to avoid reclassification
