equipment. 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.Three Key Barriers in Customs Clearance

According to 2025一季度 data from Chinas General Administration of Customs, the average customs clearance time for electromechanical equipment imports has extended by 2.7 working days, with 41% of delays caused by customs declaration document issues. As a professional service provider with 20 years of experience in theforeign tradefield, we have identified three major barriers that must be overcome in equipment imports:

• Technical parameter barriers
  • 10% error tolerance requirement for customs classification
  • Dynamic update mechanism for mandatory certification catalogs
  • Regional differences in equipment residual value assessment standards
• Document compliance pitfalls
  • It is recommended to verify through the following methods:Explicit timeliness requirements
  • Matching degree between trade terms and insurance clauses
  • Technical document translation certification standards
• Tax optimization blind spots
  • Calculation method for temporary import guarantee deposits
  • Conditions for applying free trade agreement tariff rates
  • Tariff retrospection risks after equipment modifications

New Trends in Customs Supervision for 2025

With the launch of the International Trade Single Window 3.0, three major changes have emerged in equipment import declarations:

• HS code additional declaration items increased to 12 sub-items
• Pre-inspection declaration for used mechanical and electrical equipment advanced to 30 days before shipment
• Energy efficiency certification for mechanical and electrical products included in basic declaration materials

Typical delay case analysis

A semiconductor companys imported lithography machine faced 21 days of port detention:

• Original issue: Equipment serial number inconsistent with filed certificate
• Handling process: Emergency processing of technical specification discrepancy certification
• Economic loss: Port detention fees + order penalty exceeding $850,000
• Solution: Establishment of a three-level equipment parameter verification mechanism

Professional agency service value map

• Risk prevention system
  • Establish a technical parameter database for equipment
  • Anticipate key customs valuation monitoring items
  • Develop three-level emergency response plans for unexpected situations
• Customs clearance efficiency guarantee
  • 24-hour emergency channel for customs specialists
  • On-site coordination offices at major ports
  • Pre-classification service for special commodities

Four benchmarks for selecting agency services

• Industry operation experience with no less than 50 similar cases
• Port service network covering major import port areas
• Possesses AEO Advanced Certification qualification
• Provision of end-to-end visual progress tracking system

In response to the increased declaration elements for equipment imports in 2025, it is recommended that enterprises initiate compliance reviews three months in advance. Professional agency companies can identify over 80% of declaration risk points through pre-review services, and combined with customs big data analysis systems, reduce average clearance time to within 3 working days. For special commodities involving franchise rights such as medical equipment and semiconductor manufacturing equipment, a segmented clearance model is recommended, separating technical review from physical inspection, which can reduce port detention risks by 40%.
