I.Hidden Cost Traps of Self-Declared Customs Clearance

After the implementation of the new version of the "Import Management Measures for Electromechanical Products" in 2025,a mechanical manufacturing enterprise was unable to clear customs for a batch of CNC equipment due to incorrect HS code classification,resulting in the equipment being detained at the port for 28 days.According to the data,among the equipment import cases declared by the enterprise itself:

• 72%havedocumentationcompletenessdeficiencies.
• 65%encounteredtariffclassificationdisputes
• 41%duetoTheissuetriggerscustomsinspection.

Firewall 2: Intelligent Classification System Accurately Identifies HS Codes

Through industry database comparison,the classification time for a certain laser cutting equipment was reduced from the conventional three days to two hours,with accuracy improved to 99.2%.Typical application scenarios:

• Multi-functionalcompositeequipmentcomponentdisassembly
• CalculationofResidualValueRateforImportedUsedEquipment
