Who Handles Customs Declaration for Agent Export? Full Process Analysis of Lithium Battery Export to the EU

2026 EU Market: Opportunities and Compliance Challenges for Lithium Battery Exports

In 2026,the European energy transition process further accelerates,and market demand for energy storage systems and power lithium batteries continues to grow at a high level.For many domestic battery manufacturers,the EU market remains a highly attractive strategic high ground.However,high profits are often accompanied by high thresholds.In 2026,the new version of the EU Battery Regulation has fully entered the in-depth implementation phase,putting forward more specific quantitative indicators for battery carbon footprint disclosure,recycled material ratio and supply chain due diligence.

As a professional foreign trade agency based in Shanghai with over 20 years of industry experience,we have contacted a large number of factory managers who are trying to develop the European market.For example,Mr.Meng,head of a lithium iron phosphate battery manufacturer in Jiangsu Province,recently encountered a tricky problem.Despite the excellent product quality,Mr.Meng’s production team found it difficult to cope with the EU’s complex customs declaration document requirements and strict logistics restrictions.One of his most frequently asked questions is: Under the agent export model,who is actually responsible for customs declaration?What does the factory need to cooperate with?

In the agent export structure,the legal entity of customs declaration is usually the foreign trade agency,that is,the agency declares the export to the customs.But this does not mean that the factory can stay out of it completely.In fact,agent customs declaration is a highly collaborative process,especially for Class 9 dangerous goods such as lithium batteries,the agency requires the factory to provide accurate technical parameters and compliance documents.In this process,Zhongshen acts not only as a declarant,but also as a translator and implementer of compliance rules,translating the complex EU regulatory requirements into actionable implementation lists for factories.

Core Value of Zhongshen: Reconstructing the Export Agency Service Chain

In view of the particularity of lithium battery exports to the EU,the agency services provided by Zhongshen are not simply "handling procedures on behalf of clients",but one-stop solutions based on the latest 2026 trade policies.Our core value is to help manufacturing enterprises like Mr.Meng’s minimize logistics costs,avoid inspection risks and accelerate capital return on the premise of ensuring compliance.

Under the traditional self-operated export model,factories need to train professional customs brokers and document clerks on their own,and it is difficult to cope with the changing policies of various countries.Under Zhongshen’s agency model,we integrate core links such as customs declaration and inspection,international transportation,foreign exchange receipt and payment,and export tax refund.For lithium battery products,we have specially strengthened the coordinated service of dangerous goods compliance declaration and EU Battery Passport data pre-audit,to ensure that when the goods leave Chinese ports,their documents fully meet the access standards of the destination port.

Document Module: Precisely Respond to EU Battery Passport and Data Compliance

In 2026,the EU mandates that industrial batteries and electric vehicle batteries be accompanied by a "Battery Passport".This requires exporters to provide detailed technical data,including the carbon footprint of the battery throughout its life cycle,the proportion of recycled key materials such as cobalt,nickel and lithium,and electrochemical performance.This is not only a technical issue,but also a huge challenge at the document level.

• Policy Barriers: EU customs and market regulatory authorities adopt a zero-tolerance attitude towards the accuracy of declared data.Any deviation in the carbon footprint calculation method or opaque data source may lead to cargo detention or huge fines.
• Zhongshen’s Response Strategy: We assist Mr.Meng’s enterprise in sorting out supply chain data to ensure that the data in commercial invoices,packing lists and declaration elements are completely consistent with the Battery Passport database.Our document team will review the test reports and supply chain statements provided by the factory in advance to ensure the accurate classification of HS code (usually 8507.60.00),and avoid customs clearance delays caused by classification disputes.

Customs Clearance Module: Efficient Passage of Dangerous Goods Transportation and Port Inspection

Lithium batteries are classified as Class 9 dangerous goods (UN3480 or UN3536),and are subject to strict supervision in international transportation and export customs declaration links.In 2026,the inspection intensity for false reporting and concealment of dangerous goods in Shanghai and other major ports has reached an all-time high.

• Risk Points: The biggest risk lies in packaging compliance.If the packaging of lithium batteries does not comply with the International Maritime Dangerous Goods Code (IMDG Code) or the UN38.3 test report expires,it will be directly judged as unqualified during customs inspection,resulting in the failure of goods to be loaded on board,and even the risk of return.
• Zhongshen’s Response Strategy: Zhongshen has a professional dangerous goods operation team.Before customs declaration,we will strictly check the dangerous goods packaging certificate,Material Safety Data Sheet (MSDS) and UN38.3 summary report provided by the factory.We have established in-depth cooperation with shipping companies with dangerous goods transportation qualifications to ensure that every link of booking,customs declaration and shipment meets the physical safety requirements such as the "1.2-meter drop test".Through our professional declaration,the unpacking rate of customs inspection is significantly reduced,and the customs clearance speed is improved.

Tax Refund and Foreign Exchange: Safety and Efficiency of Capital Flow

For the battery manufacturing industry with relatively thin profits,export tax refund is an important profit source for enterprise survival.In 2026,the tax department’s review of tax refund documents will focus more on the matching of logistics and capital flow.

• Operation Difficulties: Many factories worry that the delayed receipt of foreign exchange will hinder the tax refund process when exporting through agents.In addition,EU buyers usually pay by telegraphic transfer or letter of credit with a long cycle,and how to ensure the completion of declaration before receiving foreign exchange is also a major difficulty.
• Zhongshen’s Response Strategy: We provide a safe foreign exchange receipt and payment channel.Once the goods are declared and released by customs,Zhongshen can assist enterprises in foreign exchange settlement and purchase operations.In the tax refund link,we have established a complete "document filing database" to ensure that the purchase invoice,export customs declaration form and logistics document are strictly consistent.With the A-level tax credit accumulated over many years,our tax refund declaration channel is unobstructed,which usually helps enterprises get the tax refund as soon as possible and eases the capital pressure of Mr.Meng’s enterprise.

How Agency Services Improve Customs Clearance Efficiency and Tax Refund Speed

In actual operation,choosing Zhongshen for agent export can significantly improve the overall operation efficiency.Taking a batch of lithium batteries exported to Hamburg Port,Germany by Mr.Meng as an example,through our digital customs declaration system,the accuracy of data entry has increased to more than 99%,basically realizing "one declaration,one release".

We adopt the pre-declaration mode,and complete pre-classification and document review work before the goods arrive at the port area.For lithium battery products requiring commodity inspection,we use our communication mechanism with the customs to arrange priority inspection.Compared with self-declaration by factories,this pre-operation mode shortens the average customs clearance time by 1 to 2 days.In terms of tax refund,thanks to our pre-audit of documents,we avoid re-declaration caused by document inconsistency,and the tax refund arrival cycle is about 15 working days faster than the industry average.

To more intuitively show the operational differences between agent export and self-operated export,we have compiled the following comparison table:
