Risk 1: Classification disputes over multi-module integrated equipment
Typical case: An enterprise importing a rock drilling rig incurred an additional tax payment of 820,000 yuan due to separate declaration of the hydraulic control system
Countermeasures:
Prepare equipment disassembly diagrams and technical parameter comparison tables in advance
Apply for customs pre-classification ruling (2025 new regulation requires feedback within 15 working days)
Risk 2: Dynamically updated safety certification system
New certification requirements added in 2025:
Explosion-proof certification must include lithium battery pack safety test report
Fire resistance rating of operating cabin materials upgraded to UL94 V-0 standard
Solution: Establish dynamic tracking mechanism for certification documents with 3-month update cycle
Risk 3: Transportation plan design deviation
Common mistakes:
Ignoring equipment disassembly and reassembly costs caused by tunnel dimensions
Failure to consider special moisture-proof packaging requirements for underground environments
Optimization solution: Use 3D modeling to simulate loading/unloading processes and develop segmented transportation plan
Key nodes of full-process agency services
5 core stages professional agency services should cover:
Pre - preparation Stage: Standardization of equipment technical parameters
Cost control and efficiency improvement case studies
Comparative case of a mining groups 2025 import operations:
Self-operated group:
Customs clearance duration: 38 workdays
Additional expenses: 15% tariff deposit ratio
Professional agency group:
Customs clearance duration: 22 workdays
Tariff preference application rate: 92%
Data shows professional agencies can reduce overall costs by 19% and shorten equipment commissioning cycle by 41%. When selecting service providers, companies should focus on evaluating their case database completeness in special equipment field and emergency response mechanisms for customs inspections.
