Import Tips
• Ensure the substrate is free of soil, fertilizers, or pesticides, as those would change classification
• Confirm the granules are not expanded beyond natural pumice, as expanded perlite or vermiculite would be classified elsewhere
• Provide a product data sheet to CBSA showing it is unprocessed pumice
