Purificationequipment. 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.Industry-specific analysis

The global purification equipment market size is expected to exceed $48 billion in 2025, with an annual growth rate of 17.3% in imports of laboratory-grade HEPA filtration systems. These types of equipment differ from ordinary mechanical product imports and havethree characteristics: sensitive technical parameters, complex regulatory classification, and stringent logistics conditions. In March 2025, a biopharmaceutical company incurred direct losses amounting to 15% of the cargo value ($280,000) due to missing temperature control records, resulting in the detention of a cell culture purification chamber at the port.Selection dimensions for professional agency companies

When selecting purification equipment

the following capabilities should be prioritized:Import RepresentationFiltration efficiency test reports (EN1822/ISO29463)

• Technical document processing capability
  • Explosion-proof certification (ATEX/IECEx)
  • Filing (CFDA/FDA)
  • Medical EquipmentCustoms classification experience
• An 8% tariff difference between 8421.39 and 8421.49
  • Modular equipment complete/separate declaration options
  • Vibration-proof packaging for precision sensors (amplitude ≤0.3g)
• Special logistics solutions
  • Dual temperature-controlled transportation for cleanroom equipment
  • Typical case comparison in 2025

A semiconductor company importing a lithography workshop purification system

Case A:The professional agency company completed in advance:
– Pre-classification confirmation (8479.89→5% tariff)
– Preparation of UL900 certification documents
– Design of split transportation solution
Customs clearance time: 3 working days
Same equipment handled by non-professional agencies

Case B:Resulted in:
– Incorrect classification under 8421.39 (13% tariff)
– Missing NFPA flame retardant certification
– Damage due to whole machine transportation
Additional costs incurred: $72,000
Four firewalls for risk prevention and control

Establish a customs commodity classification database

• Pre - classification dispute resolution mechanism
  • Establish a customs commodity classification database
  • Archive similar case judgments within 3 years
• Dual verification of technical parameters

2025 agency service fee analysis

Professional purification equipment agency service fees typically include:
Basic service fee: 1.2-1.8% of cargo value (including document processing)
Technical Value - added Fee: $800-1500/order (parameter verification, etc.)
Risk management fee: Minimum 0.3% of cargo value (guarantee service)

It is recommended to adoptPhased payment model: 30% advance payment + 40% after customs clearance + 30% upon acceptance, effectively controlling capital risk. A German-funded purification equipment supplier reduced import costs by 9.7% in 2025 through this model.
