Import Tips & Compliance
• Classify the electron gun assembly under 8540.99.10 only if it is presented as a separate part; if imported with the CRT, it may be classified differently
• Keep detailed product documentation to support the classification
• Verify whether the electron gun is for a cathode-ray tube, as other tube types may fall under different items
