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 standard transistor without photosensitive properties
No light-to-current conversion capability; operates solely on electrical input/output.
If imported as part of computer motherboard assembly
Classified as parts of computers when imported assembled into finished motherboard rather than discrete component.
If packaged as complete optical sensor module with optics
Functions as measuring/testing optical sensor rather than discrete semiconductor device.

Import Tips & Compliance
• Provide spectral response documentation proving IR sensitivity to avoid misclassification as visible light phototransistor
• Check for radiation-hardened versions which may require 8525.82 certification if used in high-radiation environments
• Ensure RoHS compliance certification; many electronics importers face delays without material content declarations
