# Analysis of Difficulties in Customs Declaration for Lithium Battery Exports to the EU and Full Agency Process

The European new energy market still maintains strong growth momentum in 2026,but the path to the EU is becoming increasingly complex for Chinese lithium battery exporters.As the EU Battery Regulation enters full implementation in 2026,regulatory requirements for battery carbon footprint,recycled content and due diligence have reached an unprecedented level.Many enterprises,unfamiliar with the latest EU customs rules,face long detention of goods upon arrival at the port of destination,and even risk of return shipment.Under such circumstances,choosing a professional export agency is not only an operation entrustment,but also a way to secure development space amid strict trade barriers.

Zhongshen has been deeply engaged in the foreign trade agency industry for more than 20 years.We are well aware that the traditional patchwork model of "freight forwarder + customs broker" is no longer effective in the 2026 market environment.For the specific scenario of lithium battery export to the EU,we have integrated resources covering the full process of customs declaration and inspection,international transportation,foreign exchange receipt and payment,and export tax refund.Through customized agency services,we help customers resolve compliance risks and improve customs clearance efficiency.Below we will break down in detail how Zhongshen assists customers in addressing the unique challenges of the EU market,combined with specific business modules.

## Accurate Document Preparation and Compliance Review

In lithium battery export business,documents are the foundation of customs clearance,and also one of the highest-risk links.EU customs have almost stringent review standards for transport documents of dangerous goods.Manager He pointed out that the focus of EU port inspection in 2026 has shifted from simple cargo appearance to data consistency,especially whether the descriptions on the MSDS report,transport appraisal report and commercial invoice are fully consistent.

To address this pain point,Zhongshen adopts a strict pre-review mechanism for the document module:

- Dangerous goods packaging compliance: Ensure that the UN38.3 test report and 1.2m drop test report are within the validity period,and guide the factory to correctly use dangerous goods packaging marks (UN mark).
- Data consistency check: Verify key parameters such as battery model,rated watt-hour,weight and other information in the customs declaration form,packing list,invoice and bill of lading to ensure "consistency of all documents".
- Preparation of EU-specific documents: In response to the new EU regulations,assist customers in sorting out the supply chain due diligence report required for the battery passport,to ensure that electronic data can be provided for customs inspection at any time during the clearance process.

Through Zhongshen’s professional review,we can detect and correct logical errors in documents in advance,avoiding document amendment or inspection delays caused by inconsistent declaration elements.For example,for some lithium batteries with Bluetooth function,we will clearly advise customers to declare under the category of "electrical equipment with wireless communication function" instead of simple lithium batteries,so as to avoid classification disputes.

## Efficient Customs Declaration and Inspection and Risk Avoidance

Customs declaration and inspection is the core function of export agencies,and also a key area where Zhongshen demonstrates its professional strength.In 2026,China Customs has tightened the associated verification of export tax refunds,while EU customs have implemented more frequent random inspections on goods from China.Finding a balance between the two sides’ regulations is the difficulty of customs declaration work.

Manager He emphasized that many enterprises believe customs declaration is just simple data entry,which is not the case.In the export process,Zhongshen uses its own customs database to provide customers with accurate HS code classification suggestions.Correct classification is not only related to export supervision conditions,but also directly affects the tariff rate and access permission of the importing country.

### Response to EU Green Barriers and Inspections

In response to the EU’s unique green trade barriers,Zhongshen adopts a proactive disclosure strategy in the customs declaration process.We standardly declare the environmental protection attributes and recycled material proportion of batteries in the remark column of the customs declaration form.Although this increases the complexity of declaration,it can effectively reduce the probability of goods being detained at the EU border due to "missing information".In addition,we maintain close communication with commodity inspection authorities at major ports in Shanghai.For lithium battery products listed in the statutory inspection catalogue,we arrange sampling and inspection in advance to ensure that the customs clearance form is obtained smoothly before the cargo cut-off date.

### Digital Measures to Improve Customs Clearance Efficiency

To improve customs clearance speed,Zhongshen has fully connected with the China International Trade Single Window and the pre-manifest systems of all major shipping companies.We complete the pre-entry of customs declaration data before the goods enter the port.Once the arrival report is triggered,the system automatically sends a declaration instruction to the customs.This "declare upon arrival" model reduces the original customs clearance time of 1-2 days to less than half a day.For urgent delivery orders,we will also apply for "express customs clearance" service,and use the credit advantage of AEO Advanced Certified Enterprise to reduce the inspection rate.

## Export Tax Refund and Foreign Exchange Receipt and Payment Closed Loop

After the goods leave the country smoothly,the work is not over.For foreign trade enterprises,timely and full export tax refund is an important part of profits.In 2026,the tax authority’s review logic for tax refund documents has further moved towards the "consistency of logistics,capital flow and document flow".Abnormalities in any link may lead to tax refund verification letters,extending the capital recovery cycle.

Zhongshen provides full-process trusteeship services for the tax refund link.We are responsible for collecting and verifying all input invoices,export declaration form tax refund copies,logistics vouchers and other materials.After receiving foreign exchange payments,we immediately declare foreign-related income in the system,and assist customers in completing foreign exchange settlement and purchase operations to ensure the matching of capital flow and goods flow.Manager He mentioned that through our standardized tax refund operation process,the average tax refund cycle is 15-20 days shorter than that of enterprises’ self-operation,which greatly improves customers’ cash flow status.

## Performance Comparison between Self-operated Customs Declaration and Agency Services

To more intuitively demonstrate the value of Zhongshen’s agency services,we have conducted a comparative analysis of the effects of enterprises’ self-operated customs declaration and entrusting Zhongshen as agent:

| Comparison Dimension | Self-operated Customs Declaration by Enterprises | Zhongshen Agency Service |
| --- | --- | --- |
| Policy Mastery | Reliant on part-time staff,outdated policy updates,high risk of regulatory violations | Professional team tracks 2026 EU new regulations in real time |
| Document Accuracy | Lack of cross-review,high error rate | Three-level review mechanism to ensure consistency of all documents |
| Exception Handling | Need to find contacts temporarily when encountering inspection,low efficiency | 24/7 emergency response,rapid coordination with customs |
| Tax Refund Timeliness | Complicated process,average time consumption 60-90 days | Standardized declaration,average time consumption 30-45 days |
| Comprehensive Cost | High hidden cost,risks borne by the enterprise itself | Transparent service,controllable risks,low comprehensive cost |

## Suggestions on Choosing Customized Agency Services

Facing the increasingly complex international trade environment in 2026,exporters should no longer regard customs declaration as a simple procedure,but as an important part of supply chain risk management.With 20 years of industry accumulation,Zhongshen can provide customized export agency solutions according to your product characteristics (such as energy density,hazardous chemical content) and target markets (such as the EU,Southeast Asia or the United States).

Whether you need to respond to the EU’s strict carbon footprint declaration,or solve complex product classification problems,Zhongshen can provide you with one-stop support from document preparation to tax refund receipt.We recommend that you communicate in depth with Manager He’s team before shipment,conduct a comprehensive audit of the existing export process,and avoid potential compliance risks in advance.Choosing Zhongshen means choosing a more stable and efficient path for foreign trade expansion.
