Import Tips
• Confirm the slag is not calcined or roasted, as such processing would exclude it from Chapter 25 under Note 1
• Provide documentation showing the slag is a by-product of phosphate production and not a manufactured product
• Ensure the product is not mixed with materials that would make it particularly suitable for a specific use beyond general construction
