New EU Battery Regulation Takes Effect, How Can Export Agents Solve Customs Clearance and Tax Refund Problems

2026 New Energy Battery Export to EU: Practical Response Under CBAM and New Battery Regulation

In the second quarter of 2026,the EU Carbon Border Adjustment Mechanism (CBAM) officially enters the full collection period,and the carbon footprint declaration requirement of the new Battery Regulation (EU 2023/1542) will cover all industrial batteries with a capacity exceeding 2kWh.In the office of Zhongshen in Hongqiao Business District,Manager Song has just processed a batch of lithium battery cargo detained by Hamburg Port Customs due to non-compliant carbon emission data format.The value of this batch of products is about 800,000 euros,and the container detention fees and penalties incurred after 12 days of滞留 are close to 4% of the cargo value.This is not an isolated case.In the first half of 2026,the average cargo detention rate of Chinese new energy products exported to the EU increased by 210% year-on-year,and the core problems are concentrated in three aspects: incomplete carbon data chain,disconnection between CE certification and CBAM declaration,and mismatch between tax refund documents and customs codes.

The export agency system accumulated by Zhongshen over 20 years is designed specifically for such systemic risks.Different from the single transportation service of traditional freight forwarders,Zhongshen decomposes the export process into 12 controllable nodes,and embeds compliance checks for EU-specific regulations at each node.This modular operation mode keeps the export customs clearance lead time of battery products stable at 4.2 working days,and the tax refund arrival cycle is 35% shorter than that of independent declaration by enterprises.

Document Preparation Module: Pre-audit Avoids Carbon Data Traps

The core review item newly added by EU customs in 2026 is the CBAM Carbon Emission Data Sheet (CBAM Communication Template).This form requires tracing the full life cycle carbon value of the product from raw material mining to factory delivery,and synchronizing it in real time with the database version number filed by the exporter in the EU CBAM registration system.Most enterprises often make three mistakes when declaring on their own: directly converting domestic environmental assessment data,ignoring the power structure difference coefficient,and failing to update the database version number.

The operation process of Manager Song’s team is: 3 working days before the production enterprise completes packaging,Zhongshen’s carbon data review specialist will intervene,retrieve the latest power emission factor officially released by the EU (the 2026 EU average factor is 0.276kg CO2/kWh),and recalculate the product carbon value.At the same time,the system will automatically compare the data consistency between the carbon verification report issued by TUV or SGS and the CBAM template.This pre-action reduces the document non-compliance rate from the industry average of 23% to below 1.7%.

EU Customs Clearance Document List and Risk Points

• CBAM Communication Template: Must include version number V2.1 (updated in April 2026),carbon value accurate to three decimal places,unit must use tCO2e
• Battery Passport: Comply with the QR code format in Appendix II of the new Battery Regulation,needs to be linked to the EU compliance database,invalid links will lead to return of the entire batch
• CE-RED Certification Certificate: From 2026,BMS systems with wireless communication functions need to additionally provide a network security assessment report (EN18031)
• Ocean Bill of Lading Remarks Column: Must mark the CBAM registration number (format: EU-CBAM-2026-country code-enterprise code),missing marking will trigger manual inspection,increasing lead time by 3-5 days

Customs Clearance Execution Module: Digital Channel Bypasses Manual Inspection Bottleneck

The ICS2 (Import Control System 2) system launched by the customs of 27 EU countries in 2026 implements 100% electronic pre-audit for battery cargo.Zhongshen has established an API direct connection channel with customs brokers in the three hub ports of Rotterdam,Hamburg and Antwerp.After the cargo is loaded on board,Zhongshen’s system automatically captures the AMS data from the shipping company,and completes the ICS2 declaration 72 hours before the cargo arrives at the destination port.This pre-clearance mode allows the cargo to be released directly after arrival at the port,skipping the traditional manual document review process.

Manager Song mentioned a key detail: In 2026,EU customs set the sampling inspection rate for battery products from China at 8.3%,but for first-time declaring enterprises or enterprises with abnormal data,the sampling inspection rate automatically increases to 100%.The risk model trained by Zhongshen based on historical declaration data can identify 87% of high-risk declaration records before submission,and start preparation of supplementary documents in advance.For example,when the system detects that the lithium content of a batch of batteries exceeds 2g/100Wh,it will automatically trigger a secondary verification of the UN38.3 test report,and synchronize it to the EU dangerous goods declaration system (eDGD).

Tax Refund Service Module: Classified Declaration and Accelerated Channel

The export tax refund rate for new energy batteries remains at 13% in 2026,but the speed of tax refund directly affects enterprise cash flow.Zhongshen’s tax refund module adopts a classified declaration strategy: split one shipment into multiple sub-items according to customs code,trade method,and destination country,and match the optimal tax refund path respectively.Manager Song explained that this split is not a simple technical operation,but based on the in-depth application of the Measures for Classification Administration of Export Tax Refund (Exemption) issued by the State Administration of Taxation in 2026.

Specifically,Zhongshen declares battery components and BMS control systems separately.The former applies for general trade tax refund,while the latter applies for processing trade tax refund.This classification allows the BMS part to enjoy the "tax refund upon entry" policy of special customs supervision areas,and the tax refund arrives within 3 working days after the cargo enters the bonded area.For the general trade part,Zhongshen uses the accelerated channel of the "single window" of Shanghai Electronic Port,simplifying tax refund documents from the original 9 copies to 4 core documents,eliminating redundant repeated certifications.

In 2026,the State Administration of Taxation launched the paperless tax refund 3.0 system,requiring enterprises to maintain the "export tax refund filing document database" by themselves.Most enterprises have a 14% probability of triggering tax inspection due to non-standard document archiving.Zhongshen’s digital filing system automatically converts heterogeneous files such as CBAM carbon data,battery passports,and CE certificates into XML format recognized by the State Administration of Taxation according to the particularity of EU export business,with an archiving accuracy of 100%.Data from Manager Song’s team in the first half of 2026 shows that the tax inspection rate of agency clients is only 0.3%,far lower than the industry average.

Core of Efficiency Improvement: Node Parallelization and Risk Reserve Mechanism

Zhongshen transformed the traditional serial export process into parallel nodes.When the production enterprise is in the material preparation stage,carbon data review and CE certification update are launched simultaneously; when the cargo enters the port area,ICS2 pre-declaration and tax refund document pre-audit are carried out simultaneously.This parallel mode reduces the overall cycle by 60%.More importantly,Zhongshen has set up a special risk reserve to advance additional expenses caused by sudden changes in EU policies.In April 2026,the EU temporarily raised the anti-dumping deposit ratio for battery products from 5.8% to 11.2%.Zhongshen used the reserve to advance a total of €470,000 in deposits for three clients,ensuring timely release of cargo and no delay in clients’ delivery commitments.

Manager Song emphasized that the value of export agency does not lie in the speed of single-point operation,but in the ability to absorb systemic risks.When EU policies are adjusted frequently in 2026,Zhongshen’s compliance database is updated weekly,ensuring that clients always use the valid version.This real-time response mechanism is the competitive moat formed by 20 years of industry accumulation.

For new energy enterprises planning to export to the EU,choosing Zhongshen means converting complex compliance work into standardized service modules.Enterprises only need to focus on product R&D and production,and hand over professional links such as carbon data,certification,customs clearance,and tax refund to Zhongshen.This division of labor mode not only reduces compliance risk,but also improves capital turnover efficiency by more than 40%.The threshold of the EU market in 2026 is indeed raised,but professional export agency services can turn compliance costs from an uncontrollable "black swan" into a budgetable "white box".
