Import Tips

• Verify cleanroom compatibility certification (ISO 14644) to meet semiconductor import standards and avoid reclassification

• Include detailed technical specs showing ultrasonic frequency (e.g

• 40-80 kHz) for wafer processing in customs documentation

• Beware of dual-use claims; pure lab cleaners may shift to 8479.89.65 if not proven for semiconductor production
