Import Tips
• Verify tube specifications match subheading notes for television camera tubes to avoid reclassification as general CRTs
• Include detailed technical datasheets and end-use certificates proving camera application, not display use
• Check for radiation emission compliance (FCC Part 15) as photocathode tubes may require safety testing
