Import Tips
• Verify dimensions do not exceed 3mm diameter or 25mm length to avoid reclassification under broader 6914.10 provisions
• Provide manufacturer certifications confirming porcelain composition and firing process per Chapter 69 notes
• Ensure fiber channel tolerances are documented to distinguish from general ceramic insulators excluded under heading 8546
