Why is it necessary to complete the pre - inspection before the clearance of imported equipment? Professional interpretation and guide to avoid pitfalls

The Core Role of Pre - Shipment Inspection (PSI) in Machineryequipment. For example, Indonesia has the SNI certification, Thailand has the TISI certification, and the Philippines has the BPS certification. It is necessary to confirm in advance the equipment voltage (such as 380V/50Hz in Thailand), the compatibility of the CE certification, and the proof of environmentally friendly materials.According to the Measures for the Inspection and Supervision of Imported Mechanical and Electrical Products newly issued by the General Administration of Customs in 2025, mechanical equipment with a value exceeding $20,000 is mandatorily required to undergo pre - shipment inspection (abbreviated as PSI). The fundamental purpose of this system is

To prevent second - hand equipment from being declared as new productsand ensure that imported equipment complies with Chinas mandatory technical specifications. Professional agency companies can effectively avoid the risk of tariff losses of over 20% caused by misreporting of HS codes through the pre - inspection process.Four Key Steps of the PSI Process in 2025

Technical Document Pre - review Stage (3 - 5 working days)

• Check the consistency between the equipment nameplate and the contract parameters
  • Confirm the validity period of CE/UL and other certification certificates
  • On - site Inspection Implementation Stage (Key Monitoring Items)
• Detection of actual use traces of the equipment (Infrared Spectral Analysis)
  • Verification of the integrity of safety protection devices
  • Verification of the integrity of safety protection devices
• Formulation of Rectification Plan (Handling of Common Issues)
  • Conversion Plan for Incompatible Voltage Systems
  • Remedial Measures for Missing Chinese Warning Labels
• Issuance of Inspection Report (Obtaining of Clearance Vouchers)
  • Pre - shipment Inspection Certificate Issued by CCIC
  • Report of Third - party Testing Institutions Recognized by the Customs

Analysis of Typical Customs Clearance Failure Cases in the Past Three Years

In 2024, when an auto parts enterprise imported German stamping equipment, due to neglectingthe detection of equipment foundation bolt hole positions, it was found that they did not match the factory building embedded parts after arrival at the port, resulting in a renovation cost as high as 15% of the equipment value. The new regulations in 2025 specifically emphasize that the importer needs to provideelectronic filing of the equipment installation foundation drawing, and this case verifies the importance of technical review in the pre - inspection process.

Triple Value Guarantee of Professional Agency Services

• Risk Early - Warning System: Identify special certification requirements for equipment origin in advance
• Emergency response mechanism: Complete the technical rectification plan within 72 hours
• Cost Control Model: Dynamic customs clearance strategy to avoid demurrage charges

Five evaluation dimensions for selecting service providers

It is recommended that enterprises focus on examining theLocalized service capabilityagent companies, especially their familiarity with policies at major import ports such as the Yangtze River Delta and the Pearl River Delta. Agent companies with AEO advanced certification can shorten the customs clearance time by 30%, and at the same time, it is necessary to confirm whether their technical teams include professional personnel such as mechanical engineers.

A precision instrument import enterprise completed the EMC electromagnetic compatibility rectification in advance through professional agency, saving 22 customs clearance working days compared with self - declaration. This case confirmsthe decisive role of technical prediction abilityin equipment import. With the implementation of the Intelligent Document Review system by the customs in 2025, standardized and complete pre - inspection documents will become the core competitiveness for rapid customs clearance.
