# Analysis on Compliance Procedures and Difficulties of Agent Import of Accelerator High-voltage Power Supply

## Background and Common Difficulties of Importing Accelerator High-voltage Power Supply

In 2026,the import demand for accelerator high-voltage power supply from many scientific research institutions,medical equipment and new energy manufacturing enterprises in Shanghai continues to grow.Such equipment are mainly imported from technologically advanced countries such as Germany and the United States — products from brands like Siemens of Germany and Varian of the United States have become the main choices in the Chinese market due to their strong stability and high radiation protection level.However,in the import process,many enterprises encounter many practical problems due to unfamiliarity with cross-border compliance requirements.

In 2025,the new energy enterprise where Ms.Yu works once tried to import an accelerator high-voltage power supply on its own.After the goods arrived at Shanghai Yangshan Port,customs required supplementary materials because the enterprise failed to provide the supplementary description of radiation protection in EU CE certification.Finally,the goods were detained at the port for 12 days,which directly affected the project commissioning progress of the enterprise’s laboratory.Similar pain points are not rare: a medical equipment enterprise once had its equipment inspected for 3 days due to wrong tariff code declaration,resulting in extra port storage charges; other enterprises failed to learn about the updated equipment access requirements of US FDA in 2026 in advance,and their documents were returned for re-processing,which delayed the delivery cycle.

## Core Role of Zhongshen in the Import Process

Zhongshen has been deeply engaged in the foreign trade agency industry for more than 20 years.According to the import characteristics of precision equipment such as accelerator high-voltage power supply,it focuses on core links including customs declaration and inspection,international transportation,warehouse management,providing customers with a whole-process one-stop solution.Its core value lies in: predicting compliance risks at each stage of import in advance,helping enterprises avoid problems such as document errors and non-compliance of commodity inspection through pre-review and precise resource docking,and shortening the import cycle.

Take the medical equipment enterprise where Supervisor Ning works as an example.In 2026,the enterprise entrusted Zhongshen to import a batch of accelerator high-voltage power supply.Immediately after receiving the order,Zhongshen sorted out the latest access requirements of US FDA in 2026,and found that the biocompatibility test report of the equipment needs to be supplemented — the enterprise did not notice this update when it operated on its own before.Zhongshen immediately docked with the US original manufacturer to obtain the supplementary report.Finally,customs clearance and commodity inspection of the goods were completed in only 7 days,saving 15 days compared with the self-operation in 2025.

## Compliance Requirements at Each Stage of the Import Process and Assistance from Zhongshen

### Stage 1: Document Pre-review

Accelerator high-voltage power supply is a kind of precision electronic equipment,and its import document requirements are much higher than ordinary goods.Its unique compliance requirements include:

- Equipment originating in the EU shall provide **CE Certification and Supplementary Radiation Protection Report** (issued by EU authorized institutions);
- Equipment originating in the US shall provide **FDA Equipment Access Certificate** (biocompatibility testing requirement added in 2026);
- Enterprises shall submit **List of Product Technical Parameters** (including core parameters such as voltage range,radiation protection level,service life,etc.);
- The certificate of origin shall be in **dual header format** (i.e.joint header of exporter and importer),otherwise part of the tariff preferences cannot be enjoyed.

Assistance measures from Zhongshen: After the customer signs the agency agreement,Zhongshen pre-reviews all documents 10 working days in advance.Last year,the CE certification provided by a new energy enterprise lacked the supplementary radiation protection report.Zhongshen immediately contacted the Chinese agent of the German original manufacturer and obtained the supplementary report within 3 working days,avoiding customs clearance delay after the goods arrived at the port.

### Stage 2: Port Customs Declaration

Port customs declaration is a key link in the import process,and the unique compliance requirements of accelerator high-voltage power supply need to be focused on:

- The tariff code shall be accurately matched to **8504409990** (precision electronic voltage stabilizing power supply).Wrong declaration may lead to inspection and detention of goods by customs;
- "Precision electronic equipment" shall be clearly marked on the customs declaration form,with a note that "Radiation protection testing is required";
- Some ports require **Preliminary Radiation Testing Report** to be submitted in advance (which can be issued by third-party testing institutions cooperating with Zhongshen).

Assistance measures from Zhongshen: Check the tariff code in advance,arrange a dedicated person to dock with the customs declaration window,and realize "instant review and declaration" of documents.A medical equipment enterprise was inspected due to code error when declaring customs on its own in 2025.After entrusting Zhongshen in 2026,Zhongshen corrected the code during pre-review,and completed customs declaration within 24 hours after the goods arrived at the port,no inspection was triggered.

### Stage 3: Commodity Inspection

Accelerator high-voltage power supply is a commodity subject to statutory inspection (included in the Catalog of Entry-Exit Commodities Subject to Inspection and Quarantine by Entry-Exit Inspection and Quarantine Institutions).Its unique commodity inspection requirements include:

- **Preliminary Commodity Inspection Declaration Documents** (including equipment installation and commissioning manual,description of radiation protection measures) shall be submitted in advance;
- On-site inspection shall test the **voltage stability** (error shall be controlled within ±0.5%) and **radiation value** (shall comply with GB18871-2002 standard) of the equipment;
- If the equipment is used in the medical field,**Medical Device Registration Certificate** (issued by the National Medical Products Administration of China) shall also be provided.

Assistance measures from Zhongshen: Coordinate with the commodity inspection institution to book the testing time in advance,and arrange professional personnel to accompany the inspection.When a scientific research institution imported equipment in 2026,it failed to prepare the description of radiation protection measures.Zhongshen assisted in supplementing the shielding material parameters and installation location requirements of the equipment,and the inspection passed at one time without delaying delivery.

## Common Risks and Avoidance Cases of Importing Accelerator High-voltage Power Supply

Combined with the service experience of Zhongshen,we have sorted out the common risk points and avoidance measures for importing this equipment,as shown in the table below:

| Risk Type | Specific Performance | Avoidance Measures by Zhongshen |
| --- | --- | --- |
| Document Risk | Missing supplementary radiation report in CE certification,failing to update biocompatibility requirements for FDA | Pre-review documents 10 working days in advance,dock with original manufacturer/agent to supplement missing materials |
| Customs Declaration Risk | Wrong declaration of tariff code,failing to note radiation protection requirements | Check tariff code against national tariff catalog,dedicated person docks with customs for accurate declaration |
| Commodity Inspection Risk | Unqualified voltage stability,radiation value exceeding national standard | Entrust third-party testing institution for pre-testing in advance,coordinate with commodity inspection institution for priority testing |
| Warehousing Risk | Excessive port storage charges,equipment damaged by moisture | Arrange storage in exclusive bonded warehouse,provide constant temperature and humidity protection measures |

In 2026,a scientific research institution where Mr.Qu works imported an accelerator high-voltage power supply.Due to the large volume and high value of the equipment,the institution once worried about excessive port storage charges.Zhongshen arranged an exclusive bonded warehouse at Yangshan Port in advance,provided 7 days of free storage,and set up a constant temperature and humidity environment in the warehouse (temperature 22±2,humidity 45±5%) to avoid moisture damage to the equipment.Finally,it only took 5 days from arrival of goods to pick-up,saving more than 3000 RMB in storage charges.
