Import Tips & Compliance
• Provide MIL-SPEC documentation and gain certification to differentiate from consumer camera tubes
• Anti-dumping duties may apply to certain Chinese-origin Gen 3 tubes; verify country of origin carefully
• Declare photocathode spectral response (400-900nm) to confirm light-sensing classification vs thermal
