The value of professional customs brokers often lies in the following technical details:

Core service modules breakdown

• Pre - classification Service
  • Functional parameter translation and conversion
  • Key component material analysis
  • EU CE certification corresponding to GB standards
• Tariff Optimization Configuration
  • Verification of provisional tariff application conditions
  • Determination of origin under free trade agreements
  • Pre-review of tax-exempt equipment qualifications

Typical risk scenario responses

Case 1:An automaker imported welding robots, and due to translation errors in kinetic parameters leading to misclassification, the tariff was reduced by 9.7% after agency review and adjustment.

Case 2:Medicalequipment. 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.Due to the lack of pre-clearance certification from the drug regulatory department, the agency completed the filing 45 days in advance, avoiding 200,000 yuan in port detention fees.
