Import Tips
• Provide a detailed specification sheet showing the K2CO3 content and absence of additives, as any stabilizers must be for preservation only
• Confirm the product is not doped or modified for electronics use, which would fall under other headings
• Declare the end-use as glass manufacturing to facilitate customs clearance, but classification remains based on composition
