Import Tips

• Verify datasheet confirms adjustable performance features like programmable PLL or voltage scaling to justify 8542.39.00.70 classification

• Include RoHS compliance certificates and full technical specs in documentation to prevent customs reclassification to general ICs

• Watch for overvoltage protection requirements; test samples before bulk import to avoid rejection
