Import Tips
• Keep the quicklime dry during transport, as exposure to moisture causes hydration and could alter classification
• Provide a technical data sheet showing calcium oxide purity and particle size to support the tariff classification
• If the quicklime is used in a controlled industrial process, no special permits are typically required, but verify with CBSA if the end-use involves regulated chemicals
