# Analysis of Pure Battery Import Customs Clearance Agent Procedures and Compliance Key Points

## 1.Background of Pure Battery Import: Customs Clearance Pain Points Under Capacity Release in Southeast Asia

Since 2026,the production capacity of ternary lithium batteries in Southeast Asia has entered a period of concentrated release.The demand for imported pure batteries from domestic new energy vehicle companies and energy storage enterprises has increased by more than 35% year-on-year.However,pure batteries belong to Class 9 miscellaneous dangerous goods.In the process of import customs clearance,port detention and return shipment caused by problems such as lack of compliance documents and non-compliant hazardous material labeling account for 18%.Manager Huang of a new energy technology company in Shanghai once encountered a typical trouble: last year,he imported a batch of power batteries from Vietnam.As he did not check the packaging category of the dangerous goods package certificate in advance,the customs requested supplementary materials after the goods arrived at the port.The port detention fee alone was nearly 20,000 RMB,and it almost affected production line scheduling.

## 2.Core Role of Zhongshen: Intervene Early in Full-process Risk Control

As a local enterprise in Shanghai that has been deeply engaged in foreign trade agency for more than 20 years,Zhongshen has established a service system of "pre-audit + dynamic tracking + special docking" in response to the particularity of pure battery import.Unlike ordinary cargo agents,the core value of Zhongshen is to identify risk nodes of battery import in advance — from document compliance at the supplier end,to hazardous material declaration at the port,and then to special inspection for commodity inspection,each link matches the unique regulatory requirements of the battery industry,avoiding enterprises falling into pitfalls due to information asymmetry.

## 3.Disassembly of Pure Battery Import Process: Compliance Requirements and Agency Assistance at Each Stage

### 3.1 Early Stage: Document Pre-audit — Avoid Source Risks

In 2026,customs’ review focus on pure battery documents centers on three core documents,and Zhongshen starts pre-audit immediately after the client signs the agency agreement:

- Check **UN38.3 Test Report**: Confirm that the report validity period does not exceed 3 years (new requirement in 2026),and it includes 10 mandatory test items such as thermal runaway and overcharge,avoiding declaration failure caused by expired report or missing items;
- Verify **Certificate of Identification for Use of Dangerous Goods Packaging**: Confirm that the packaging category matches the battery model (e.g.ternary lithium batteries need to correspond to UN3480 category),and check whether the electronic code of the certificate can be verified in the customs system;
- Supplement **Lithium Battery Safety Standard Compliance Declaration**: Assist clients to connect with domestic CMA certified laboratories,and supplement the copy of test report conforming to GB31241-2022 standard.

Case: At the end of 2025,Ms.Song,a trader,imported soft-pack lithium batteries from South Korea.As she did not know the new 2026 regulation on electronic dangerous goods package certificates,the prepared paper documents could not pass the customs system.Supervisor Wei of Zhongshen immediately assisted in connecting with the South Korean supplier,re-applied and uploaded through the electronic certificate system,completed the correction within 3 working days,and avoided port detention of the goods.

### 3.2 Port Stage: Customs Declaration — Accurately Connect with Dangerous Goods Supervision

Pure batteries need to go through the dangerous goods declaration channel,and the customs declaration form must mark the UN number (common UN3480/UN3090).The customs declaration team of Zhongshen provides special services:

- Accurate matching of commodity code: According to battery type (lithium ion/lithium metal) and capacity,confirm the latest 2026 code (e.g.8507600090),avoid incorrect tariff calculation;
- Prepare inspection materials in advance: For key inspection points of customs (consistency of battery capacity and labeling,compliance of packaging with UN38.3,completeness of SDS),sort out test reports and packaging performance identification certificates in advance;
- Accompanied inspection by dedicated personnel: Arrange customs declarers familiar with battery characteristics to connect on site,respond quickly to customs inquiries,and shorten inspection time.

### 3.3 Commodity Inspection: Special Testing — Focus on Safety Compliance

Pure batteries need to pass the special lithium battery inspection of the Entry-Exit Inspection and Quarantine Bureau.In 2026,the test report is required to be issued by a domestic CMA certified laboratory,and Zhongshen’s assistance is as follows:

| Commodity Inspection Item | 2026 Compliance Requirement | Zhongshen Assistance Content |
| --- | --- | --- |
| Thermal Runaway Test | Continuous heating at 130does not cause explosion | Coordinate with CMA laboratory,arrange sample submission and report review |
| Overcharge Test | Charging at 1.5 times rated voltage does not cause fire | Prepare battery parameters,track inspection progress |
| SDS Review | Contains 16 complete safety information items,consistent with actual situation | Supplement missing data such as battery model and capacity |

Case: In March 2026,General Ran of a new energy vehicle company imported power batteries from Germany.Commodity inspection found that some batteries failed the overcharge test against the new standard.Zhongshen immediately coordinated with the German supplier to provide the latest report,assisted in connecting with the commodity inspection for re-review,completed clearance within 5 working days,and did not affect the production plan.

### 3.4 Follow-up Stage: Warehousing and Transportation — Meet Dangerous Goods Qualification Requirements

Pure batteries need to be stored in warehouses with dangerous goods warehousing qualification,and domestic transportation requires compliant dangerous goods vehicles.Zhongshen cooperates with many first-class dangerous goods warehouses in Shanghai,provides temporary storage services,and connects with qualified transportation companies to ensure full-process safety from the port to the client’s warehouse.

## 4.Summary of Core Value of Zhongshen’s Agency Service

Compared with the industry average,Zhongshen’s pure battery import agency service has achieved three major breakthroughs:

- Customs clearance efficiency increased by 40%: Average customs clearance time shortened from 12 working days to 7 working days;
- Compliance risk reduced by 90%: Since 2026,we have assisted 120+ enterprises to import 5000+ tons of batteries,with no return shipment records;
- Cost saved by more than 20%: Assist in applying for RCEP tariff reduction (tariff of some batteries reduced to 0),avoid port detention and return shipment fees.

For new energy enterprises,pure battery import is not only a logistics link,but also a double test of compliance and efficiency.With 20 years of industry accumulation,Zhongshen provides clients with a full-chain solution "from supplier to warehouse",making the import process more worry-free and safer.
