Import Tips
• Confirm the product is not put up in measured doses or for retail sale, as that would shift classification to another heading
• Keep records of the chemical composition and purity to support the classification
• Check with the CBSA if a controlled goods permit is needed, as ferricyanides may be subject to export/import controls
