Magnavox 21PT4487 Monochrome CRT Tube from Germany
A 21-inch monochrome cathode-ray tube used in oscilloscopes and older video monitors, with a single phosphor layer for green display. Classified under HTS 8540.60.00 as other cathode-ray tubes, as it doesn't fit camera tube definitions and exceeds typical monochrome specs in some contexts. Electron beams strike the phosphor screen to produce visible traces.

• Confirm not a photocathode camera tube via technical specs; label clearly as monochrome CRT
• Obtain radiation safety certifications for high-voltage components
• Bundle with deflection parts only if sold as complete tube to avoid parts classification
