Core Assessment Criteria for Water Purifier Import Agencies
- Check operational experience in water purifier categories: In 2026,customs has upgraded 3C access and energy efficiency label verification for home appliances.Agents without category experience may miss 3C exemption applications or misclassify reverse osmosis purifiers,causing 2% overpaid tariffs or misdeclaration penalties.
- Check port coverage: Importers shipping to Shenzhen/Ningbo/Qingdao ports face 2,000-5,000 RMB transfer fees and 3-5 day delays with local-only agents.Choose nationwide cross-port declaration agencies.
- Check full-link risk control: Anticipate anti-dumping duties,RCEP tax reduction,and customs valuation risks.Avoid "pass-the-buck" agents who only handle customs declaration—any logistics/payment/commodity inspection issue halts the entire shipment.
