Import Tips
• Ensure the funnel is fired after shaping and not merely dried, as unfired articles are excluded from Chapter 69
• Keep documentation showing the ceramic composition and firing temperature to support classification
• Verify it is not an electrical insulator or fitting, which would fall under headings 85.46 or 85.47
