Reliable sourcing and import agency services.
I am a domestic trading company specializing in outdoor energy storage products. We recently received an order for ternary energy storage lithium batteries imported from South Korea.
We have never imported battery products before, so we contacted two small agents who claimed they could handle it, but last week the goods were rejected after arriving at the port, citing non-compliance with Dangerous Goods Packaging Certificate requirements. Now the goods are stuck at the port, generating detention charges of thousands of yuan every day.
My boss is urging me to resolve this quickly, otherwise we will default on the contract and have to compensate the customer. I now want to find a reliable agent, and want to clarify the exact process of acting as an agent for importing batteries, what qualifications and documents need to be prepared in advance, how to avoid detention again, and how to clear the goods as soon as possible?

The full-chain operation of acting as an agent for importing batteries starts with pre-review of documents. The first step is to confirm the product name，HS Code，and type of the battery，and verify the three core documents in advance: UN38.3 Test Report，MSDS，and Dangerous Goods Packaging Certificate. The Dangerous Goods Packaging Certificate must be consistent with the actual packaging specifications，which is the most problematic link. Many small agents ignore the specification comparison and declare directly，which eventually leads to return or cargo detention.
The connection of core nodes is divided into three key parts: First，in the overseas space booking link，inform the shipping company of the hazardous goods classification of the battery in advance，confirm the reserved space for the corresponding level of hazardous goods，and avoid space booking failure leading to cargo rejection after arrival. Second，complete the pre-review of customs declaration documents 3 days before arrival，compare the consistency between document information and declaration data，and correct errors in advance. Finally，connect with the terminal in advance to reserve the corresponding storage space for hazardous goods，so as to avoid high detention charges caused by no available space after arrival.
For abnormal response plans，if there is a discrepancy in document information，prioritize arranging to delete the original declaration and re-declare while correcting the Dangerous Goods Packaging Certificate information. Completing the abnormal handling within 72 hours after arrival at the port can apply for a 50% reduction in detention charges. If there is a customs inspection，prepare the full set of test reports in advance for submission，which can shorten the inspection cycle by at least 3 working days.
For final compliance implementation，after customs clearance is completed，promptly verify the batch information of the goods，retain the full set of declaration documents for three years for future inspection，in line with the latest document retention regulatory requirements of customs in 2026. Operate according to this process can reduce the risk of cargo detention or return to less than 1%，and also help you take away the detained goods as soon as possible to reduce additional losses.

Imported batteries are Class 9 hazardous goods, so their packaging must comply with UN hazardous goods packaging regulations. Attention should be paid to clear printing of marks on the packaging, and the UN number, hazardous goods marks, and consignor and consignee information must be complete and accurate, with no ambiguity or damage. MSDS must comply with the latest GHS standards. Most domestic ports require formal translations issued by domestically recognized institutions, and uncertified English versions issued by overseas original factories cannot be used directly.
If bare batteries (without packaging) are imported, it is necessary to customize compliant outer packaging for hazardous goods in advance and complete packaging performance inspection before declaration. Many customers ignore the packaging requirements for bare batteries and ship them directly, leading to failure to clear customs after arrival. If the original Dangerous Goods Packaging Certificate does not meet domestic requirements, an off-site Dangerous Goods Packaging modification can be applied for, and after completing performance inspection again, it can be declared compliantly, which can avoid return of the entire batch of goods and recover most of the losses.

When declaring imported batteries, HS Code classification is a core risk point. The HS Codes for power energy storage batteries, consumer batteries, and power batteries are different, and the corresponding regulatory document requirements also vary. Incorrect classification will lead to deletion of the original declaration and re-declaration, or even be identified as false declaration affecting the enterprise's credit.
In 2026, the customs' focus on price verification for battery products is on the implicit pricing of original factory supporting accessories. It is necessary to prepare original factory invoices, foreign exchange payment vouchers, and transaction contracts in advance to prove the authenticity of the declaration price.
If there is a price verification dispute, a third-party price appraisal report can be provided to speed up dispute handling. For integrated customs clearance declaration, it is necessary to confirm in advance that the regulatory requirements of the place of origin and the port are consistent, so as to avoid the order being pending due to system verification failure.

Foreign exchange payment for imported batteries must comply with the latest compliance requirements for current account foreign exchange receipts and payments, and purchase and payment of foreign exchange must be completed through compliant channels. The corresponding transaction documents, invoices, and customs declaration forms must be retained to ensure the consistency of cargo rights, funds, and documents, and avoid being monitored and controlled by banks.
If paying in RMB, settlement can be done through CIPS Cross-Border Interbank Payment System. Compared with SWIFT settlement, it has faster arrival, lower rates, and can also avoid exchange rate fluctuation risks. If paying through an offshore account, it is necessary to report the transaction background to the bank in advance and provide a full set of import documents, so as to avoid the situation where funds are detained and pending, which affects the pickup progress.

Inspection of imported batteries mainly focuses on the authenticity of the Dangerous Goods Packaging Certificate, battery classification, and UN mark verification. During machine inspection, it is necessary to adjust the cargo stacking method in advance, turning the mark side of the battery packaging towards the outside of the container, to facilitate machine inspection scanning and identification, and reduce the probability of unpacking inspection. If unpacking inspection is required, arrange an unpacking team familiar with hazardous goods operations to arrive in advance to avoid safety issues caused by irregular operations.
If testing and appraisal are required, prioritize choosing testing institutions designated by customs, which can shorten the inspection cycle, and reports are usually issued within 5 working days. Reports from non-designated institutions may not be recognized, extending the customs clearance time. After inspection is completed, check the seal information in a timely manner, and arrange pickup after confirming the seal is intact, to avoid situations where cargo damage or shortage cannot be held accountable.

As hazardous goods, for sea freight space booking for imported batteries, space needs to be confirmed 10 days in advance. Most shipping companies have fixed space quota restrictions for hazardous goods batteries, and temporary space booking is prone to cargo rejection, leading to schedule delays. If importing from East Asia, direct shipping can be chosen, which has at least 7 days less voyage than transshipment, and can also avoid additional costs from secondary security checks at transshipment ports.
For container detention charges, a 14-day free detention period can be applied to the shipping company in advance, which is 7 days more than ordinary goods, effectively reducing logistics costs. If changing ports, it is necessary to inform the shipping company of the hazardous attributes of the battery in advance and complete the transshipment port hazardous goods transit procedures in advance to avoid port detention.

For large batches of imported batteries, VAT Deferral can be applied for, which does not require advance payment of value-added tax during customs clearance, and can alleviate the capital pressure of enterprises, especially for high-value energy storage battery orders, reducing large amounts of capital occupation. VAT Deferral needs to meet the access requirements of customs, and enterprises with good tax credit records and no illegal declaration records can apply.
If importing batteries through cross-border related transactions, it is necessary to complete pricing compliance filing in advance to avoid being identified as profit shifting by tax authorities, resulting in anti-avoidance investigation risks. Pricing can be reasonably planned according to actual transaction situations to optimize tax costs while maintaining compliance.
