Import Tips

Verify photosensitive characteristics with spectral response data sheets to confirm classification as photosensitive transistor vs. standard transistor (8541.41)

Include detailed component datasheets and test reports proving light sensitivity for CBP review during entry

Avoid misclassification as LED (8541.41-8541.49.95) by documenting transistor functionality rather than emission
