Import Tips
• Confirm the chamotte is not mixed with hydraulic binders or other additives, as such mixtures are excluded from Chapter 25
• Provide documentation of the calcination process and intended use as a raw material
• Verify the product is not considered a prepared refractory mix, which would fall under heading 38.16
