Import Tips

• Verify isolation voltage rating (e.g

• 2.5kV) and CTR (current transfer ratio) specifications match datasheet to confirm classification as optical coupled isolator under 8541.49.80

• Include manufacturer datasheets showing LED-phototransistor optical coupling in commercial invoice; declare as 'photosensitive semiconductor device' not general diode

• Avoid misclassification as LED assemblies by confirming single-channel isolator function; check for RoHS compliance documentation required for electronics imports
