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
