A Complete Guide to Customs Clearance and Risk Mitigation for Importing Slow Wire EDM Machines in 2025

Special Regulatory Requirements for Importing Slow Wire EDM Machines

As core equipment in precision machining, importing slow wire EDM machines (EDM Wire Cutting Machine) involves3 mandatory certificationsand5 types of technical documentsAccording to the latest 2025 customs classification rules, machines with machining accuracy ≤0.005mm should be classified under8456.3010tariff code, with an 8% tariff rate. However, special attention must be paid to whether the machine is equipped with an automatic tool changer (ATC), as this affects the calculation basis for import VAT.

Step-by-Step Customs Clearance Process in the Wujiang Region

• Pre-declaration preparation phase (15-20 working days)
  • Notarization of equipment technical parameters (including key metrics like spindle power and positioning accuracy)
  • Filing for special equipment safety licenses (validity shortened to 6 months)
  • It is recommended to verify through the following methods:and verification of updated CE certification documents
• Key on-site inspection items (2025 updates)
  • Verification of CNC system versions (imports of machines with specific control software versions are prohibited)
  • Coolant composition testing (18 new environmental indicators added)
  • Residual value assessment of equipment (complete maintenance records required for used equipment)

Comparative analysis of typical cases

Case study: A Wujiang precision mold manufacturer encountered port detention when importing German equipment in March 2025

• Self - declaration: Due to incorrect HS code classification under 8457, triggering customs inspection control, resulting in storage fees of 120,000 CNY
• Professional agency solutions: Through pre-classification service confirming tariff code 8456.3010 in advance, adopting split declaration strategy saved 238,000 CNY in VAT

Three-dimensional evaluation for agency service selection

• Verification of professional qualifications
  • AEO Advanced Certification qualification (can reduce inspection rate by 50%)
  • Specialized filing for mechanical and electrical products import
• Cost control capability
  • Tariff guarantee insurance replacing deposit (releasing 90% capital pressure)
  • Transportation route optimization (Japan-Korea route can shorten by 5-7 days)
• Emergency response mechanism
  • 48-hour technical dispute resolution
  • Local inspection fast track service

2025 import trend forecast
