2026 Complete Analysis of Agent-led Energy Storage Export Business Process and In-depth Sorting of Compliance Points

Particularity of Energy Storage Export Business Chain and Value of Process Sorting

In 2026,the global energy transition process is accelerating,and the export scale of energy storage products continues to rise.Lithium batteries,energy storage battery packs and related supporting equipment have become an important engine for foreign trade growth.These products are inherently hazardous,and their export process is far more complex than ordinary goods.Disputes over customs classification,hazardous goods packaging specifications,transportation safety requirements,and multi-country certification standards are intertwined,and any omission in any link may lead to cargo detention,fines or even return.At the beginning of this year,an enterprise of General Manager Chen had an entire batch of goods detained at Shanghai Port for two weeks due to inconsistent versions of the UN38.3 test report,resulting in direct losses of over 1 million RMB.Against this background,systematically sorting out the standardized process of agent-led energy storage export and identifying key control points is of practical urgency for export enterprises to avoid systemic risks.

Phase 1: Export Qualification Preparation and Product Compliance Certification

Qualification preparation before energy storage product export is the cornerstone of all subsequent work.The core goal of this phase is to ensure that both the enterprise entity and the product itself meet domestic and foreign regulatory thresholds.Key actions include: completing the record-filing of foreign trade operators,obtaining HS code,and completing enterprise record-filing for entry-exit inspection and quarantine.At the product level,the certification procedure must be launched 6-8 months in advance according to the requirements of the target market.In 2026,the EU New Battery Regulation enters the full implementation phase,and the requirements for carbon footprint declarations in CE certification are more detailed; in the North American market,the UL9540A test report has become a mandatory requirement for market access of large-scale energy storage systems.Common problems focus on insufficient estimation of certification cycle,inconsistency between test samples and mass-produced products,and delayed certificate update.Supervisor Wu once served a Jiangsu-based client,whose energy storage battery module could not clear customs after arriving at Rotterdam Port because the battery core supplier was changed and the product was not re-submitted for testing.

Zhongshen’s role in this link is reflected in advance consultation and full-process tracking.We assist clients to sort out the certification list of the target market,coordinate domestic qualified laboratory resources,pre-review technical documents,and ensure that the information in the test report fully matches the customs declaration documents.For enterprises exporting for the first time,we simulate customs inspection scenarios,identify detailed defects such as packaging marks and warning labels in advance,and avoid rework in subsequent links.

Phase 2: Accurate Preparation of Customs Declaration Documents and Declaration Execution

Customs declaration is the most technically demanding link in the energy storage export process.In 2026,customs supervision parameters for lithium battery products have been further refined,and HS code classification error is still the most frequent declaration error.According to factors such as capacity,application,and whether it contains mercury or cadmium,energy storage battery packs may be classified into different subheadings such as 8507.60 and 8507.80,with significant differences in tax rates and regulatory conditions.Key actions include: accurately confirming HS code,completely filling in declaration elements,standardizedly preparing the hazardous goods packaging use identification certificate,and submitting the entry-exit goods customs clearance form simultaneously.Common problems include: vague filling of "capacity range" in declaration elements,wrong hazardous goods category marking,and data contradiction among supporting documents.Data from Shanghai Port in the first quarter of 2026 shows that the inspection rate of lithium battery goods increased by 15% year-on-year,among which the proportion of document amendment caused by non-standard declaration exceeds 40%.

Zhongshen’s customs declaration team implements a double-person review mechanism.Supervisor Wu leads colleagues to conduct pre-classification ruling for each shipment of energy storage goods,and compares similar product classification cases with historical customs data.In the declaration link,we use an electronic document preparation system to automatically capture key parameters from certification reports,contracts and invoices,reducing manual input errors.When encountering customs inspection,our on-site staff will bring a full set of technical documents to communicate directly with inspection officers,explain product structure and certification details,and greatly shorten inspection time.Last year,we assisted a Shenzhen-based client to compress the inspection and release process that originally took 3 working days to be completed within 6 hours.

Phase 3: Hazardous Goods Logistics Transportation and Port Operation Coordination

As Class 9 hazardous goods,energy storage products have extremely strict safety and compliance requirements in the transportation link.In 2026,the International Maritime Organization (IMO) revised the International Maritime Dangerous Goods Code,further tightening the requirements for packaging marking and container stowage segregation of lithium batteries.The goal of this phase is to ensure that the goods safely arrive at the port of departure and successfully pass the dual review of the shipping company and the port.Key actions include: entrusting a qualified hazardous goods packaging manufacturer to produce UN-standard packaging,pasting correct hazardous goods signs and lithium battery marks,submitting a complete Dangerous Goods Declaration (DGD) to the shipping company,and coordinating the arrangement of port hazardous goods yards.Common problems include: packaging materials not meeting UN standards,wrong size and position of marks,and delayed space approval from shipping companies.Some shipping companies implement space restriction policies for lithium battery cargo,and space application needs to be made 3-4 weeks in advance during peak season.

Zhongshen has established a long-term cooperation mechanism with the hazardous goods transportation departments of mainstream shipping companies.Supervisor Wu declares the technical parameters of the cargo to the shipping company in advance to lock in space and freight rate.We supervise packaging manufacturers to strictly implement in accordance with the packing instructions (PI965-PI970) in the UN38.3 test report,and take photos for archiving and reference.At the port operation end,we arrange special personnel to track the whole process of cargo arrival,storage and loading,to ensure smooth connection of all links.In April 2026,we successfully controlled the total time of picking up a 20-ton energy storage container from the factory to loading at Shanghai Port within 72 hours,securing the valuable sailing schedule for the client.

Phase 4: Security Control of Foreign Exchange Receipt and Payment and Exchange Rate Risk Hedging

A single shipment of energy storage products has high value,so capital security and cost control in the foreign exchange settlement link directly affect enterprise profits.In 2026,the two-way fluctuation range of RMB exchange rate has increased,and the exchange risk faced by export enterprises has risen.The core goal of this phase is to ensure the safe arrival of foreign exchange and optimize settlement cost as much as possible.Key actions include: reviewing the payment capacity of foreign buyers,monitoring foreign exchange arrival,completing foreign exchange verification,and selecting appropriate settlement timing.Common problems include: delayed payment by foreign buyers,traps in letter of credit terms,profit eroded by exchange rate fluctuations,and inability to obtain tax refund due to non-standard foreign exchange declaration.Some emerging market clients prefer cross-border RMB settlement,but the exchange rate conversion method is opaque,which hides risks.

Zhongshen provides collection and payment agency services.The foreign payment for General Manager Chen’s order is directly transferred to our foreign exchange regulatory account.After confirming the arrival of funds,we notify the client immediately and handle settlement according to their instructions.Supervisor Wu tracks exchange rate trends daily,and within the client’s authorization,selects relatively high exchange rates for batch settlement to smooth the impact of exchange rate fluctuations.For large orders,we assist clients to lock in forward exchange rates and avoid depreciation risks.In the first half of 2026,by optimizing settlement timing,we helped a Zhejiang-based energy storage enterprise gain nearly 80,000 RMB in additional exchange income.All foreign exchange operations are completed within the regulatory system of the State Administration of Foreign Exchange,ensuring the consistency of document flow,capital flow and cargo flow in the tax refund link.

Phase 5: Accurate Export Tax Refund Declaration and Tax Compliance Management

Export tax refund is the last link of capital recovery for energy storage export enterprises,and also the link with the highest tax risk.In 2026,the State Taxation Administration has tightened the tax refund review for lithium battery products,especially emphasizing that the product name and specification on the input invoice must be fully consistent with those on the export customs declaration.The goal of this phase is to obtain the full tax refund quickly.Key actions include: VAT special invoice authentication,data entry into the export tax refund declaration system,sorting out document filing,and responding to tax authority verification.Common problems include: delayed issuance of input invoices,inconsistent product name with customs declaration,missing filed documents,and inconsistent tax refund declaration data with customs data.Some enterprises have their tax refund applications rejected because they mistakenly marked energy storage batteries as "battery accessories" on invoices.

Zhongshen’s tax refund team starts tax refund preparation immediately after the goods are declared and exported.We compare every data item on the customs declaration,invoice and contract,and require suppliers to re-issue invoices for inconsistent items.Supervisor Wu has established a tax refund declaration progress dashboard to ensure that the declaration is completed within 3 working days after all documents are complete.For the newly added "dynamic adjustment of export enterprise classification management" mechanism introduced by the State Taxation Administration in 2026,we assist clients to improve internal risk control processes,strive to maintain a classification rating of Class II or above,and ensure that tax refund arrives within 10 working days.We also regularly review tax refund data,analyze the change trend of tax refund rates,and provide a basis for clients to adjust procurement strategies.

Core Value and Efficiency Improvement of Full-process Agency Service

The five phases of energy storage export business are closely linked,and any broken link will trigger a chain reaction.Zhongshen has condensed over 20 years of foreign trade agency experience into a standardized operation process,and set up risk control gates at each key node.We do not simply handle procedures on behalf of clients,but act as clients’ foreign trade risk control officer and efficiency engine.From early intervention in the certification consultation phase,to accurate classification in the customs declaration link,from space guarantee for hazardous goods logistics,to exchange rate optimization in foreign exchange settlement,to zero-error execution of tax refund declaration,every link helps clients reduce time cost and avoid hidden losses.

In 2026,the foreign trade environment is becoming more complex,and the cost and risk of enterprises building their own foreign trade teams continue to rise.Choosing a professional agent like Zhongshen is essentially outsourcing non-core business to a more efficient execution entity,allowing enterprises to focus resources on product R&D and market development.After six months of cooperation with us,General Manager Chen’s company shortened the average export cycle of energy storage products from 45 days to 32 days,reduced the customs declaration error rate to zero,and advanced the arrival time of tax refund by nearly two weeks.This efficiency improvement is directly converted into tangible profits and market share in fierce market competition.
