1N4148 Signal Switching Diode from China
The 1N4148 is a small signal fast-switching diode used in electronic circuits for signal demodulation, detection, and high-speed switching applications. It falls under HTS 8541.10.00.70 because it is a non-photosensitive, non-LED diode with a maximum continuous forward current rating of less than 0.5A (typically 200mA). Commonly found in consumer electronics like radios and computers.

Import Tips
• Verify diode specifications including maximum current rating <0.5A via datasheet to confirm HTS 8541.10.00.70 classification
• Include manufacturer datasheets and test reports in documentation to prove non-photosensitive and non-LED nature
• Avoid misclassification as LEDs (8541.41+) by ensuring no light-emitting properties; common pitfall in mixed shipments
