Import Tips
• Ensure the product is not mixed with other chemicals, as that could reclassify it under Chapter 36 (pyrotechnic products)
• Provide a purity certificate to demonstrate it is natural witherite, not a prepared additive
• Verify particle size is achieved by grinding only, not chemical processing
