Aging TestEquipment ImportsTypical customs clearance difficulties

Under the latest customs supervision system in 2025, the import of environmental simulation equipment presents three significant characteristics:The document review cycle is extended by 15%,The quarantine standards for wooden packaging are upgraded,Electromagnetic compatibility testing becomes a new thresholdData from the inspection and quarantine bureau of a certain province shows that among the return cases of aging test equipment in 2024, 32% are due to the lack of technical documents, and 28% are due to non - compliant packaging treatment.

Key nodes in the preparation of qualification certifications

Equipment for different application scenarios needs to be matched with the corresponding certification system:

• Industrial - grade equipment: CE certification + China Metrological Instrument Type Approval
• Equipment for scientific research: A final - user statement and research project filing are required
• Equipment in the medical field: Dual requirements of FDA registration certificate (for US - made equipment) and NMPA filing

Special reminder: The new energy efficiency label system (EU 2025/178) implemented by the EU starting from 2025 will affect the equipment customs clearance speed. It is recommended to prepare an energy efficiency test report in advance.

Cost control in the design of transportation solutions

Select the optimal transportation combination according to the equipment characteristics:

• Precision temperature - controlled equipment: Constant temperature throughout the journey + Special vehicle transportation from the port to the laboratoryMaritime TransportationLarge walk - in test chambers: Modular disassembly for transportation + Assembly service at the destination
• High - value detection systems:
• Combined transportation of main components + marine - supporting componentsAir TransportationA case of a multinational logistics enterprise shows that adopting a split - type transportation plan can reduce the overall logistics cost by 22% and shorten the customs clearance time by 14 days.

A case study from a multinational logistics company shows that adopting asplit shipment solutioncan reduce overall logistics costs by 22% and shorten customs clearance time by 14 days.

Tariff Optimization Strategy in 2025

Achieving Tax Optimization through Precise Classification by HS Codes:

• It is recommended that environmental test chambers be classified under item 9031.80
• Equipment with a data acquisition system needs to be declared separately
• Under the RCEP Agreement, a 3%-5% tariff reduction can be applied for

It is worth noting that in 2025, the General Administration of Customs newly addedVerification of equipment agea requirement that for the import of used equipment, an original factory depreciation certificate needs to be provided additionally.

Case Studies of Typical Customs Clearance Failures

A certain technology companys import of a UV aging chamber produced in Germany encountered a return of goods:

• Mistake 1: Failure to obtain a radiation safety permit (the equipment contains the UV-C band)
• Mistake 2: The wooden pallet was not fumigated in accordance with IPPC
• Mistake 3: The technical parameter table did not include a Chinese translation

After rectification, adopta combined solution of pre-classification service + certification agency + bilingual document packageThe second declaration saved 18 working days.

Import RepresentationSelection Criteria for Services
