Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If produced by blowing or molding but retains character of unworked glass article under chapter note (a)
Blown or molded glass remains in 7003 if pre-annealing processes don't constitute 'worked' per chapter definitions.
If imported as part of complete oscilloscope liquid crystal display assembly instead of CRT glass
LCD parts for measuring instruments fall under 9013, not glass envelopes of Chapter 70.
If the cone is fused with the bulb/faceplate envelope before import
Complete open bulb envelopes for CRTs classify under 7011.10, separate from individual cone parts.

Import Tips & Compliance
• Document end-use in oscilloscopes/scientific instruments to distinguish from consumer TV/monitor cones if questioned
• Ensure no absorbent or reflecting coatings applied, as chapter notes exclude those from unworked glass but may affect part status
• Batch imports may trigger valuation scrutiny; maintain transfer pricing docs for related-party glass suppliers
