Import Tips
• For museum/retrofit imports, provide provenance documentation to avoid commercial use scrutiny
• Test for vacuum integrity pre-shipment; leaks cause customs rejection as 'spent' under 8549 notes
• Pair with compatible power supply certifications to demonstrate complete camera tube function
