Why are imported equipment worth millions frequently detained at the port?

2025第一季度Data from the General Administration of Customs shows that the average customs clearance time for industrial equipment goods is 42% longer than that of ordinary goods. The person in charge of a manufacturing enterprise frankly said: Our CNC machining center was detained at the port for two weeks, and we lost 180,000 yuan just in container detention fees. This reveals that for large-scaleequipment. 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.The fundamental difference from traditional trade - the special commodity attributes require professional service support.

The three technical thresholds for the import of large - scale equipment

The first dimension: Management of transportation technical parameters

• Oversize equipment requires special declaration:
  • If the single weight exceeds 45 tons, a feasibility report for road transportation needs to be submitted
  • If the length exceeds 18 meters, a special vehicle passage permit needs to be applied for
• Transportation requirements for precision instruments:
  • Shockproof level must meet ISTA 3A standard
  • The temperature fluctuation of the constant - temperature container is controlled within ±2℃

The second dimension: Tariff compliance management

• Risks brought by HS code classification errors:
• An enterprise classified an industrial furnace into item 8514, but it should actually be classified into item 8417, resulting in overpayment of tariffs by 370,000 yuan
• It is recommended to verify through the following methods:Verification of the integrity of the documents:
• The ASEAN FORM E certificate requires verification of 15 anti-counterfeiting elements

The third dimension: Technical access review

• Matching of the mandatory certification catalog:
• Pressure vessels need to obtain TSG certification
• Electrical equipment must pass CCC certification
• Verification of environmental protection technical standards:
• Non - road mobile machinery must meet the National IV emission standards

The value realization path of professional agency services

A case of a provincial - level key project shows that through professional agency services:

• Transportation cost optimized by 23%: Adopting multimodal transport solutions
• Customs clearance efficiency increased by 60%: Pre-classification + Two-step declaration mode
• Compliance risk reduced by 100%: Completing compliance transformation of 17 technical documents

6 golden standards for choosing service providers:

• Customs AEO Advanced Certification qualification
• At least 5 successful cases of large - scale equipment imports
• Own customs declaration team covering major ports
• Have the operation qualification for project logistics
• Successful records of tariff dispute resolution
• Provide a full - process visual management system

Three early warning mechanisms for risk prevention and control

The prevention and control system established by professional agency companies includes:

• Technical parameter pre - review mechanism:
  • Initiate the filing of equipment parameters 120 days in advance
  • Complete 3D simulated loading test
• Tariff planning sand table deduction:
  • Establish more than 3 tax classification pre - plans
  • Prepare 5 sets of tax reduction and exemption application plans
• Emergency plan reserve:
  • Manual for Handling 20 Common Emergency Situations
  • 7×24-hour Emergency Response Team

When a mining group imported a ball mill with a diameter of 9 meters, the agency company completed 13 technical rectification suggestions in advance, avoiding a technical transformation loss of 5 million yuan after arrival at the port. This confirms the irreplaceability of professional services in complex trading scenarios.
