Export of New Energy Storage Batteries to the EU: Practical Responses Under 2026 Regulatory Pressure

In 2026,the EU’s new Battery Regulation will enter full implementation phase,and the coverage of the Carbon Border Adjustment Mechanism (CBAM) will be extended to the battery industry chain.Chinese new energy storage battery export enterprises face three compliance thresholds: upgraded CE certification,launch of the Battery Passport system,and mandatory disclosure of carbon footprint data.The Port of Rotterdam (Netherlands) and Port of Hamburg (Germany) have implemented differentiated inspection standards for battery cargo,with inspection rates rising by 8-12 percentage points compared to the same period in 2025.Some enterprises have experienced tax refund cycles extending to over 90 days due to incorrect classification code declarations,leading to a sharp increase in capital occupation pressure.At the beginning of the year,Mr.Yang’s team took on commissions from three Yangtze River Delta battery manufacturers,whose products cover household energy storage systems and industrial and commercial energy storage cabinets,with target markets covering Germany,France,and Italy.During the initial self-inspection stage,it was found that customers generally had problems such as expired UN38.3 test report versions,missing data fields in the Battery Passport,and vague definition of carbon accounting boundaries.The modular service system formed by Zhongshen’s 20 years of industry accumulation has shown differentiated value in the export scenario of highly regulated products.

Document Preparation Module: Pre-positioned Layout of Compliance Documents

In 2026,the EU will implement an enhanced version of the Market Supervision Regulation for battery products,shifting the technical document review from sampling system to declaration system.Zhongshen’s document team has sorted out seven types of core documents: CE-RED certification certificate,Battery Passport XML data package,carbon footprint verification statement,UN38.3 test summary,transport condition appraisal letter,dangerous goods packaging performance inspection report,and origin certificate documents.The document team led by Ms.He found that the fields of "recycled material proportion" and "recycled metal source" in the Battery Passport need to sign a data sharing agreement with upstream suppliers,otherwise they cannot pass the verification of the EU entry system.Zhongshen assisted customers in reconstructing their supplier management system six months in advance,moving the data collection node forward to the cell procurement stage.For carbon footprint calculation,the team introduced ISO 14067 standard modeling tools to distinguish two accounting boundaries: cradle-to-gate and cradle-to-grave,to avoid customers from repeatedly calculating transportation emissions.In March 2026,a customer’s cargo was detained by Dutch customs for using the 2025 version of the CE certificate.Zhongshen urgently coordinated with the designated Dutch certification body to conduct a remote audit,completed the certificate update and customs filing within 72 hours,and the cargo was exempt from being returned.

Dynamic Classification Code Matching Mechanism

There are ongoing disputes over HS code classification for energy storage batteries.The tariff difference between the two subheadings 8507.60 and 8507.80 reaches 4 percentage points,and the tax refund rate differs by 6%.Zhongshen has established an intelligent matching database for product parameters and tariff notes,which automatically classifies products based on 12 technical indicators such as battery chemical composition,energy density,and cycle life.In 2026,customs have tightened the definition standards for "lithium-ion" and "lithium-polymer".The team updated the declaration element template in time,incorporating details such as electrolyte state and separator material into the declaration specifications.Mr.Yang reported that this mechanism increased the one-time pass rate of his company’s tax refund declarations in the first quarter from 73% to 98%,and shortened the average tax refund arrival time to 18 working days.

Customs Clearance Execution Module: Differentiated Port Strategy and Pre-control of Inspection Risks

Customs authorities of EU member states have significantly different regulatory standards for battery products.The Port of Hamburg (Germany) focuses on the integrity of Battery Passport data and the authenticity of carbon footprint verification,with an inspection cycle usually of 5-7 working days; the Port of Rotterdam (Netherlands) focuses on transport safety labels and packaging compliance,with an on-site unpacking rate of over 30%.Zhongshen has established a dual-port parallel strategy,flexibly selecting entry channels based on the customer’s cargo value,delivery time sensitivity,and product technology maturity.High-value,technically complex energy storage cabinets are prioritized for the Port of Hamburg,using Zhongshen’s AEO mutual recognition qualification with Hamburg Customs to implement the pre-ruling procedure; battery modules with a high degree of standardization are chosen for the Port of Rotterdam,and the team’s on-site personnel pre-check packaging labels in advance,controlling the inspection pass rate to over 95%.

Dynamic Update of Transport Condition Appraisal

In 2026,the International Maritime Organization (IMO) will implement annual revisions to the maritime classification of lithium batteries.Some energy storage systems will be reclassified from UN3480 to UN3481,and the packaging instruction will be changed from PI965 to PI966.Zhongshen’s logistics team has established a quarterly update mechanism,obtaining the latest revised text of the International Maritime Dangerous Goods Code in the first month of each quarter,and synchronously updating the transport condition appraisal letters for customer products.A batch of 5MWh containerized energy storage stations led by Ms.Gong had thermal runaway test data changes due to the firmware upgrade of the Battery Management System (BMS).The team promptly initiated the re-appraisal procedure,obtained the new appraisal report 72 hours before shipment,and avoided the risk of carrier rejection.

Tax Refund and Verification Module: Dual Control of Classification Accuracy and Declaration Timeliness

In 2026,the State Taxation Administration will fully implement the "paperless" export tax refund policy,but the requirements for the accuracy of classification codes have been simultaneously increased.Zhongshen’s tax refund team has established a three-level review mechanism: the primary review compares product technical specifications with tariff notes,the intermediate review verifies the consistency between purchase invoices and customs declaration forms,and the senior review evaluates the matching degree between business models and customs classification guidelines.A photovoltaic-storage hybrid project led by Mr.Ke exceeded the threshold defined by the tariff for the integration of inverters and battery packs.The team successfully declared the entire system as battery products by submitting product disassembly videos and functional module descriptions,increasing the tax refund rate from 9% to 13%,with a single batch of additional tax refunds reaching 470,000 yuan.

Foreign Exchange Receipt and Payment and Exchange Rate Locking Coordination

In 2026,the fluctuation range of the RMB exchange rate has expanded,and the payment terms for energy storage battery export orders have generally been extended to 90-120 days.Zhongshen’s foreign exchange team provides forward exchange rate locking and option combination schemes,embedding exchange rate risk clauses in the contract signing process.The "batch exchange rate locking + dynamic adjustment" model designed by Director Jin allows customers to initiate the first exchange rate locking when the order execution rate exceeds 30%,and then complete the full locking in three installments according to the production progress.This scheme helped Mr.Yang’s company avoid exchange rate losses of about 1.2 million yuan in the second quarter,while maintaining capital scheduling flexibility.

Empirical Evidence of Efficiency Improvement: Service Value from Data

Mr.Yang’s company accumulated a total export value of 8.6 million USD for energy storage batteries to the EU in the first half of 2026.The comparison before and after Zhongshen’s agency service shows that: customs clearance time has been reduced from an average of 14 days to 9 days,the inspection rate has dropped from 18% to 6%,the tax refund cycle has been shortened from 45 days to 16 days,and capital turnover efficiency has increased by 42%.Ms.He’s review pointed out that the core optimization points lie in the pre-positioned document preparation and dynamic adjustment of port strategies.In the traditional model,enterprises usually start organizing documents only after the cargo is collected at the port.Zhongshen advances the document work to the production scheduling stage,ensuring that all compliance documents are in a "ready to use" state when declaring customs.For the EU Battery Passport system,the team has developed a data interface conversion tool that can directly read the cell batch information from the customer’s ERP system,automatically generate XML format documents that meet EU standards,and reduce manual intervention time by 80%.

Risk Early Warning Mechanism

In 2026,the European Commission launched market supervision random inspections of battery products,focusing on verifying the authenticity of carbon footprint data.Zhongshen has established a customer risk classification model,which divides customers into three levels A,B,and C based on product technical complexity,supply chain transparency,and historical compliance records.Level A customers enjoy fast-track services,while Level C customers trigger enhanced review procedures and need to submit additional supply chain traceability certificates.A new customer led by Ms.Gong exported for the first time and was rated as Level C due to imperfect supplier management system.The team spent two weeks assisting them in establishing a secondary supplier data collection mechanism,and finally passed the French customs inspection smoothly.

Customized Service Decision-making Path

Different technical routes and target market combinations correspond to differentiated agency service plans.For lithium iron phosphate energy storage systems exported to Germany,it is necessary to focus on strengthening the recycled material proportion data in the Battery Passport; for ternary lithium household energy storage products entering the Italian market,priority should be given to solving the matching problem between transport condition appraisal and packaging instructions.Zhongshen provides modular combined services,and customers can choose three cooperation models: full outsourcing,single-link enhancement,or consulting services based on their own product characteristics,supply chain maturity,and internal team capabilities.Director Jin suggested that enterprises exporting to the EU for the first time should adopt the full outsourcing model,and after completing 2-3 order cycles,gradually transition to single-link enhancement,and finally achieve independent operation by the internal team.For enterprises that have basic customs declaration capabilities but lack experience in interpreting EU regulations,the consulting service model is more cost-effective.Zhongshen provides quarterly regulatory update interpretations and remote support for emergency issues.

In the third quarter of 2026,the EU will launch the carbon footprint grade labeling system for battery products,and products that have not completed carbon accounting will face market access bans.Zhongshen has laid out the carbon service product line in advance,and jointly with third-party verification institutions provides customers with full-process services from carbon data modeling to obtaining verification statements.Mr.Yang decided to include his company’s entire range of energy storage products in Zhongshen’s carbon service plan,and is expected to complete the carbon footprint verification of the first five models by the end of September,ensuring that they obtain market access qualifications before the new EU regulations take effect.Choosing an agency partner with in-depth industry knowledge and forward-looking policy research capabilities has become a key decision for export enterprises to maintain competitiveness in a complex trade environment.
