Import Tips
• 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
