HS code selection for laser confocal microscopes directly affects a 6.5% tariff difference. Its recommended to adopta dual verification method of four-digit code verification + functional parameter comparison:

• Distinguish between ordinary microscopes (9011.80) and digital imaging systems (9018.90)
