Import Tips
• Ensure the product is not mixed with fertilizers or other additives, as that may shift classification to Chapter 31
• Declare the correct moisture content, as duty is based on dry weight per statistical note 1
• Keep records of the production process to show it is slaked lime, not quicklime
