Import Tips
• Provide detailed technical specs confirming photocathode and cathode-ray functionality to justify 8540.20 classification over general picture tubes
• Include end-use documentation showing incorporation into professional TV cameras to prevent reclassification as consumer electronics parts
• Ensure radiation shielding certifications if applicable, as high-spec variants may qualify for 8525.82 alternatives
