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
