Import Tips
• Confirm the sulfur has not been sublimed, precipitated, or made colloidal, as these forms are excluded from Chapter 25
• If the sulfur contains added anti-dusting agents, ensure they do not render it suitable for a specific use
• Keep records of the Frasch process to demonstrate the crude nature of the product
