Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing refractory materials like carbides for high-heat applications
Refractory ceramic goods (6901-6903) precede and take precedence over 6914 per Chapter notes.
If specialized for laser alignment ferrules
Auxiliary optics for lasers classify under Chapter 90 instruments.
If made primarily from carbon or graphite composites
Chapter 68 covers articles of stone, plaster, cement, asbestos, or carbon.

Import Tips & Compliance
• Declare exact material (alumina/zirconia) and provide XRF analysis to distinguish from porcelain subheading
• Package individually to prevent damage to precision channels, and note fragility on commercial invoice
• Confirm no metal plating; plated versions may classify as parts of connectors under 8536
