Water electretAnalysis of Specificity

As a core component of medical purification systems,the import of water electret devices faces significant technical barriers.According to the new version of the "Regulations on the Import Supervision of Medical Devices" issued in 2025,such devices must simultaneously meet the following requirements:As core components of medical purification systems,water electret devices (Water Electret Device) have significant technical barriers for import.According to the 2025 revised Medical Device Import Supervision Regulations,such equipment must meet dual standards ofQuality Management CertificationandCE IVD In Vitro Diagnostic Device DirectiveThe double standards.Special attention should be paid to HS code classification during import declaration.Under the current classification:

• Industrialelectretequipment:8543.70.9000(7%tariff)
• Medical-gradewaterelectretequipment:9018.90.6000(5%tariff+13%VAT)

The three major risks of independent imports.

According to the statistics of the General Administration of Customs for the first half of 2025,the abnormal declaration rate of self-customs clearance for waterproofing equipment reached 38%.The main problems are concentrated in the following aspects:

• Missingtechnicaldocuments
  • Theoriginalmanufacturer’sMaterialSafetyDataSheet(MSDS)wasnotprovided.
  • ElectromagneticCompatibilityReport(EMC)versionexpired
• Logistics configuration error
  • Failuretouseanti-staticpackagingresultedinequipmentdamage.

  • Theimportlicensedoesnotmatchtheequipmentspecifications.

Comprehensive Breakdown of the Entire Professional Agency Service Process

The standard operating procedure for premium proxy service providers consists of six key stages:

• PreliminaryTechnicalAssessment(3-5workingdays)
  • Pre-complianceReviewofEquipmentParameters
  • MatchingofApplicableTariffPreferencePolicies
• Document preparation phase (7-10 working days)
  • Prepareabilingual(Chinese-English)technicalspecificationdocument

Highlights of Policy Changes in 2025

The latest regulatory requirements for the import of water-electret equipment:

• NewlyaddedNanomaterialSafetyAssessmentReportSubmissionrequirements
• Thevalidityperiodofimportlicenseshasbeenshortenedfrom3yearsto2years.
• AdditionalcustomsinspectionElectretchargedensitydetectionProject

It is recommended that importers focus on the equipment.Charge decay rateAccording to the new regulations,the annual attenuation rate for medical-grade equipment must be ≤5% (previously ≤8%),while industrial-grade equipment must be ≤12% per year.Professional agencies can provide pre-testing services to avoid additional costs from technical adjustments after arrival at the port.
