1N4148 Signal Switching Diode
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If maximum current exceeds 0.5A
Diodes with higher current ratings >0.5A fall into the next statistical suffix within the same heading.
If imported as diode parts or unmounted assemblies
Parts of diodes or incomplete assemblies are classified separately under the 'parts thereof' provision.
If mounted on circuit boards as electrical apparatus
When diodes are mounted/packaged with other components for electrical apparatus function, they shift to Chapter 85 heading 8536.

Import Tips & Compliance
• 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
