# Full Process Analysis and Key Node Control Points for Imported Portable Ultrasound Machine Agency

## Practical Difficulties of Importing Portable Ultrasound Machines from Europe,the US and Japan

In the first quarter of 2026,Ms.Zhang’s team from the equipment department of a domestic tertiary hospital planned to introduce a batch of portable ultrasound diagnostic instruments from Germany for rapid bedside assessment in emergency departments.The equipment is valued at around 450,000 euros,with a weight of only 3.5 kg per unit.This seemingly simple transaction encountered three types of problems in subsequent operations: first,the definition of the CCC certification catalog is vague,and the customs questioned whether the product falls into the scope of compulsory certification; second,the clinical verification data in technical materials did not meet domestic review standards; third,it was found during destination inspection that the label did not mark domestic agent information.This batch of equipment was detained at Shanghai Port for 23 full days,incurring total container detention and storage fees of more than 80,000 yuan.This situation is not an isolated case.As Class II or Class III medical devices,portable ultrasound machines involve multiple thresholds in the import process including registration certificates,CCC certification,commodity inspection and price review.Any omission at any node will lead to interruption of the entire chain.

After the intervention of Supervisor Lan’s team from Zhongshen,the product technical structure was reorganized,and it was confirmed that although this model is a portable device,its probe frequency range touches the boundary of compulsory certification.Supervisor Lan retrieved the revised description of the medical device CCC certification catalog issued by the Certification and Accreditation Administration of China at the end of 2025,submitted written classification opinions to the customs,and coordinated with the German original manufacturer to supplement technical documents complying with domestic clinical evaluation guidelines.The label problem was solved by affixing supplementary labels complying with Article 15 of the Regulations on the Supervision and Administration of Medical Devices.The entire remedial cycle was shortened to 6 working days,and the equipment was finally delivered to the hospital smoothly.

## Compliance Element Identification in the Document Pre-review Stage

The core of document pre-review for portable ultrasound machine import is to distinguish which subcategory the product belongs to in the Medical Device Classification Catalog.According to the latest classification standards implemented in 2026,portable ultrasound machines with spectral Doppler function and probe frequency exceeding 10MHz may be classified into Class III management.This distinction directly determines subsequent registration certificate requirements,CCC certification mode and commodity inspection sampling ratio.

After receiving an order,Zhongshen will first require the client to provide product technical white papers,the original manufacturer’s ISO13485 certificate,and overseas marketing certification documents.Supervisor Lan’s team will check technical parameters page by page,especially key indicators such as probe frequency,imaging mode and measurement function.There was once a case of a palm-sized ultrasound machine imported from the US,where materials provided by the client did not clearly mark the central frequency of the probe,only stating "broadband".Supervisor Lan required the original manufacturer to issue a specific frequency range certificate,and it was found that its upper limit reached 12MHz,which falls into the scope of Class III device management,requiring a Medical Device Registration Certificate instead of a simple filing certificate.This pre-identification avoided subsequent port return risks.

CCC certification is another key point.In 2026,the Certification and Accreditation Administration of China revised the implementation rules for CCC certification of medical devices,clarifying that "handheld" and "portable" ultrasound equipment can be included in the self-declaration evaluation method if they are only used for ordinary ultrasound examination.However,devices with advanced functions such as interventional guidance and contrast imaging still require type testing.Zhongshen will communicate with designated certification institutions in advance to confirm whether the product is eligible for self-declaration,and assist enterprises in completing certification system filing.The entire cycle has been shortened from the previous 90 days to less than 30 days.

## Key Points of Classification and Price Review in the Port Customs Declaration Link

There is great room for dispute over the HS code classification of portable ultrasound machines.Some enterprises classify them under 90181291 (ultrasonic scanning devices),while others classify them under 90181990 (other electrical diagnostic devices).The MFN tariff rate of both tax codes is 4%,but the latter does not involve automatic import license management,so some enterprises try to avoid supervision through this classification.In 2026,customs has intensified verification of the accuracy of medical device classification,and special inspections have been carried out in ports such as Shanghai and Guangzhou.

When handling such goods,Supervisor Lan’s team from Zhongshen will submit an application for pre-ruling on classification to the customs classification department in advance,attached with product structure drawings,working principle descriptions,and classification precedents of overseas customs.There was once a batch of portable ultrasound machines made in Japan,where customs initially determined they should be classified under 90181291.However,Supervisor Lan provided a technical explanation that the product does not have the complete imaging chain of traditional B-ultrasound machines,and customs finally approved classification under 90181990,saving enterprises the time required to apply for automatic import licenses.

Price review is another difficulty.Portable ultrasound machines have rapid technological updates,and transaction prices are greatly affected by configuration.Customs usually refers to the prices of similar equipment imported in the same period.If the declared price is lower than the price warning line mastered by customs,a questioning procedure will be launched.Zhongshen will assist enterprises in preparing price composition explanations,including original manufacturer price lists,discount policies,and transportation and insurance cost allocation details.In March 2026,a trading company imported 5 German ultrasound machines with a declared unit price of 28,000 euros,which customs considered too low.Supervisor Lan retrieved the global sales data of the original manufacturer in the fourth quarter of 2025,proving that the price was a normal discount price for bulk procurement,and customs finally accepted the declaration.

## Commodity Inspection and Release and Destination Supervision Handling

Portable ultrasound machines are legal inspection commodities,with a high port inspection rate.In 2026,customs and market supervision departments jointly launched the "Special Rectification of Medical Device Quality and Safety",and the sampling rate of imported ultrasound equipment has been increased to 20%.The inspection focuses include: validity of registration certificates,CCC certification marks,Chinese labels,and whether undeclared probe accessories are夹带.

Before goods arrive at the port,Zhongshen will pre-review the content of Chinese labels.According to the Regulations on the Administration of Medical Device Instructions and Labels,labels must include product name,model,specification,name,address and contact information of the registrant or filer,name,address and production address of the manufacturer,registration certificate number,production date,service life and other information.There was once a batch of equipment that was required to be rectified by the port because the label did not mark "domestic agent" information.Supervisor Lan’s team contacted the German original manufacturer overnight,generated supplementary labels through electronic signature,and completed affixing in the customs supervision warehouse,avoiding return.

Destination inspection is another key link.Portable ultrasound machines usually need to be unpacked and inspected at the final place of use to check equipment serial numbers,configuration lists,and whether they are old mechanical and electrical products.In 2026,some ports have stricter standards for the identification of old mechanical and electrical products,and used demonstration machines and prototypes may be identified as old mechanical and electrical products and prohibited from import.Zhongshen will guide the client to prepare a "new product statement" in advance,and provide an "unused certificate" issued by the original manufacturer.For demonstration machines that really need to be imported,it will assist in handling old mechanical and electrical product filing procedures.

## Foreign Exchange Receipt and Payment and Tax Treatment Practice

The import of portable ultrasound machines involves large amounts of foreign exchange payment.In 2026,the State Administration of Foreign Exchange implements post-verification for single foreign exchange payments exceeding 500,000 US dollars.When acting for foreign exchange payment,Zhongshen will keep a complete set of materials such as contracts,invoices,customs declarations,and transport documents to ensure the traceability of the authenticity of the payment background.Supervisor Lan’s team also assists enterprises in choosing the optimal payment time to avoid exchange rate fluctuation risks.There was once an order with a contract amount of 620,000 US dollars.Supervisor Lan suggested that the enterprise adopt the installment payment method,30% prepaid,70% paid against the copy of the bill of lading,which not only meets the requirements of the original manufacturer,but also reduces exchange rate exposure.

In terms of value-added tax treatment,the import of portable ultrasound machines is applicable to a 13% tax rate.Zhongshen will assist enterprises in accurately calculating the dutiable value,especially whether royalties,warranty fees,etc.should be included in the dutiable value.In 2026,customs has stricter supervision on the inclusion of technology license fees in the price review scope.Supervisor Lan’s team will evaluate the enterprise’s technology introduction agreement in advance to determine which fees need to be declared,so as to avoid the risk of subsequent tax supplementary payment.

## Practical Case: Full-process Agency Avoids Triple Risks

In April 2026,a regional medical device distributor planned to import 12 portable ultrasound machines from Japan for the configuration of primary medical institutions.The client,Ms.Zhang,was not familiar with the import process,and only provided Japanese quotations and color page materials.After taking over the case,Supervisor Lan from Zhongshen found three potential risks:

- First,the product technical parameter table indicates "support for contrast imaging",which belongs to Class III devices,but the client only handled the Class II filing certificate;
- Second,the CCC certificate provided by the Japanese side is an old version,and the self-declaration information has not been updated according to the 2026 new regulations;
- Third,the contract price term is CIF Shanghai,but the insurance rate is significantly lower than the market level,and customs may question the actual freight.

Supervisor Lan’s team intervened in three steps: first,assist the enterprise to apply for registration certificate change to the provincial drug administration,clarify the product management category as Class III,and submit clinical evaluation data for supplementary explanation; second,guide the Japanese certification responsible person to log in to the China Quality Certification Center system,update self-declaration information,and obtain the new version certification number; finally,recalculate freight and insurance premiums,adjust the contract amount according to the market fair price,and prepare price explanation materials.

After the goods arrived at the port,customs carried out sampling inspection,focusing on checking CCC certification marks and Chinese labels.Supervisor Lan conducted a pre-inspection in the warehouse in advance,found that the label did not mark "import agent" information,and immediately arranged to affix supplementary labels.The whole process from arrival to release took only 4 working days,which was 80% shorter than the historical cycle of the client’s self-operation.After accounting,Ms.Zhang found that the agency service fee was only one third of the detention cost.

## Service Value and Efficiency Conversion of Zhongshen

The professional agency for portable ultrasound machine import essentially integrates scattered regulatory requirements into an executable process plan.The value accumulated by Zhongshen over 20 years is reflected in three levels: first,pre-risk identification,through technical parameter pre-review and document cross-verification,to expose problems before goods are shipped; second,parallel process processing,registration certificate handling,CCC certification,and transportation arrangement are carried out simultaneously to shorten the overall cycle; third,emergency resource allocation,when disputes over inspection,price review,and classification occur,it can quickly mobilize multiple resources such as customs,market supervision,and certification institutions to respond.

The regulatory environment in 2026 pays more attention to the accuracy of compliance.As a technology-intensive product,the import agency of portable ultrasound machines is no longer a simple customs declaration operation,but a comprehensive service that integrates medical device regulations,customs classification,foreign exchange management,and tax planning.Among the cases currently handled by Supervisor Lan’s team of Zhongshen,the average customs clearance time is controlled within 5 working days,the one-time pass rate of documents exceeds 95%,and the incidence of price review disputes is less than 3%.Behind these data is the experience precipitation of hundreds of cases similar to Ms.Zhang’s.

For enterprises planning to import portable ultrasound machines,the core considerations for choosing a professional agency should include: whether they have special experience in medical device import,whether they are familiar with the latest CCC certification rules,whether they have successful cases of customs classification pre-ruling,and whether they can provide full-chain services from registration to release.The operation standards established by Zhongshen in these four dimensions can be directly converted into compliance guarantee and cost savings for the client.
