After the implementation of the newly revised Measures for the Administration of the Import of Mechanical and Electrical Products by the General Administration of Customs in 2025, a precision instrument import enterprise was fined 30% of the cargo value due to incorrect HS code classification. This warns us that the import of mechanical equipment is by no means a simple matter of document submission. The value of a professional customs broker is reflected in its ability to control details.
Analysis of key control points in the import process
The basic import process for mechanical equipment in 2025 shows three major changes:
The pre - declaration time limit is shortened: Complete manifest transmission 24 hours before arrival at the port (originally 48 hours)
Upgrading of environmental protection inspection: New energy efficiency level verification requirements added (CE certification shall include energy consumption parameters)
Increase in the electronicization rate of documents: The commercial invoice must be attached with a 3D equipment structure diagram (in PDF format)
Core service modules of professional agents
Classification dispute resolution
Case: Coordination of classification disputes for a certain semiconductor equipment under Chapter 87/Chapter 84 (saving 12% in tariffs)
Skills for modular splitting declaration of newly added equipment functions in 2025
Design of special transportation plans
Comparison of filing time limits for over - limit equipment transportation by road/waterway (data in 2025)
Update of international certification requirements for shock - proof packaging (ISTA 7E standard)
Tax optimization system
Application of new regulations on value - added tax carry - over refund in the import link
Dynamic comparison model of free trade agreement rates and MFN rates
New changes in customs clearance practices in 2025
According to the latest announcement of the General Administration of Customs, the following three points need special attention:
For the import of used equipment, a service life verification report (signed and sealed by a third - party institution) must be provided
Update of the detection standard for lubricant residue (ISO 4406:2025)
For the batch - by - batch import of complete sets of equipment, associated declaration must be handled (EPC system connection)
Evaluation dimensions for choosing a customs declaration agent
Verification of professional qualifications
Priority for AEO advanced certified enterprises (inspection rate reduced by 50%)
Records of transportation filing for special equipment (no less than 20 cases in the past three years)
Risk control ability
Classification error rate ≤ 0.3% (industry average 1.2%)
Emergency handling time limit for port - detention accidents < 4 hours
Configuration of value - added services
Comparison of bonded warehousing and general trade import plans
Early warning system for technical trade measures (dynamic tracking of TBT/SPS)
Enlightenment from typical dispute cases
In the import case of a certain German precision machine tool, the agency service provider completed in advance:
Application for Pre - classification Opinion (Saving 5 working days for customs clearance time)
Vibration Coefficient Test of Transportation Route (Reducing the risk of equipment damage)
Qualification Recognition of Local Taxpayers (Shortening the tax refund cycle to 15 days)
Ultimately, the equipment installation and commissioning time was advanced by 22 days compared with the original plan, highlighting the value of professional services.
