Industrial pure waterequipment. 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.New market trends

The rapid development of domestic semiconductor manufacturing and biopharmaceutical industries in 2025 has driven a 17.8% year-on-year increase in imports of industrial pure water equipment. However, the latest data from the General Administration of Customs shows that the error rate in import declarations for such equipment is as high as 32%, mainly concentrated in three areas: equipment parameter determination, health permit filing, and energy efficiency standard verification.

Key Node Analysis of the Entire Import Process

Professional agency services should cover the following core aspects:

• Technical document pre-review
  • Flow rate conversion (must specify the correspondence between GPM and m3/h)
  • Resistivity parameter verification (testing conditions for 18.2MΩ·cm)
• Customs declaration elements processing
  • HS code dual confirmation (cross-checking for 8421/9027 category)
  • Applicability determination of special origin clauses
• On-site inspection response strategies
  • Compliant reassembly plan for pretreatment system disassembly and transportation
  • Separate declaration techniques for EDI modules and RO membrane components

Three major changes in customs clearance supervision for 2025

According to the requirements of General Administration of Customs Announcement No. 83:

• Pre-approval of hygiene permits: Reverse osmosis devices must obtain water-related product approval certificates in advance
• Energy efficiency grading management: Equipment with water production rate below 65% will be subject to environmental tax
• Component traceability requirements: Pressure vessels must provide original ASME certification

Equipment selection guide to avoid pitfalls

Selection recommendations based on 300+ import cases:

• Water quality compatibility verification: Pay attention to TDS differences between North American standards and domestic water sources
• Flow rate redundancy design: Recommend configuring system capacity at 120% of nominal value
• Consumables compatibility testing: Verify whether filter specifications comply with domestic supply systems

Value embodiment of professional agency services

Special capabilities that quality agency companies should possess:

• Pre-classification database (covering 5000+ equipment model parameters)
• Localized emergency network (resolving on-site inspection disputes within 48 hours)
• Technical document reconstruction capability (compliant processing of non-standard equipment parameters)

Analysis of Typical Case Disposals

Key Points Revealed by a Biopharmaceutical Companys Import Case:

• Original manufacturers technical documents lacked Chinese version of health and safety declaration
• Expired material certification documents for pretreatment tank
• Control system software version inconsistent with declaration

Post-import market service connection

Complete service chain should include:

• Commodity inspection coordination during equipment commissioning
• Continuous supply guarantee for consumables import
• Filing change services during technical upgrades
