More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the phototransistor is part of an ambient light sensor module with additional components
When the phototransistor is integrated into a module with other elements, it may be classified as a photosensitive module rather than a standalone device.
If the phototransistor includes an integrated circuit for signal conditioning
Electronic integrated circuits with processing functions may fall under heading 85.42, which takes precedence over other headings per Chapter Note 12.
