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 meets high-speed camera specs (50ns resolution, >225k fps)
Qualifies as high-speed television/digital camera component per subheading note.
If semiconductor-based transducers (non-transistor)
Different semiconductor architecture like photodiode or photothyristor rather than transistor.
If for semiconductor manufacturing equipment
Classified as parts of machines for semiconductor manufacture rather than discrete device.

Our AI classifier can analyze your specific product and recommend the correct HTS code with confidence.
Import Tips & Compliance
• Document response time specs (<1μs) to distinguish from standard phototransistors under same heading
• Include application circuit diagrams showing light-to-current conversion to support classification
• Avoid classifying arrays as 'sets' under GRI 3(b); each transistor classified individually
