I am the head of a small and micro enterprise that has just transformed into foreign trade. Recently, I entrusted an agency company to export a batch of electronic products to the EU for the first time. Yesterday the agent sent me the draft customs declaration for confirmation, and I got stuck on the "Declaring Unit" field -- should it be filled with our company name or the agent's company name? I heard from peers that wrong filling of this field will lead to declaration rejection by customs, even cargo detention and port congestion. Now our cargo is already waiting for container loading in the warehouse of Shanghai Port, and there are only 3 days left until the sailing date. I am so anxious that I can't sleep well at night. What I fear more is that if it is filled incorrectly, will the subsequent export tax refund be affected? After all, our small company has thin profit margins, and we really can't afford any problems with tax refund. I would like to ask experts, how to fill this field correctly to be compliant, and is there any specific judgment criterion?

The filling of the Declaring Unit field in agent export customs declaration shall be determined according to the nature of the entrustment agency agreement and the customs declaration mode. First，pre-audit the rights and obligations clauses in the agency agreement: if the "dual-title" declaration mode is adopted，the Declaring Unit field shall be filled with the name of the agency company，and the name and unified social credit code of the principal shall be indicated in the "Remarks" field at the same time，if it is the "single-title" mode (the agent only provides services，and the principal bears the declaration responsibility by itself)，the name of the principal shall be filled.
Attention shall be paid to the connection of core nodes: before submitting the customs declaration，confirm the regulatory conditions corresponding to the customs code (HS Code) with the agency company，and ensure the logical consistency of the Declaring Unit field and the Operating Unit field -- if the Operating Unit is the principal and the Declaring Unit is filled with the agent，the Agency Declaration Entrustment Letter signed by both parties shall be provided (the electronic version can be uploaded through the China International Trade Single Window).
In terms of contingency plans for abnormalities，if a filling error is found，an application for "customs declaration amendment" shall be submitted through the Single Window before customs clearance conclusion: if the declaration has been concluded but not released，a written statement and a copy of the agency agreement shall be submitted to the on-site customs，if the declaration has been released，it is necessary to contact the customs for "post-correction"，but this may affect the progress of tax refund.
The key to compliance implementation is to retain a full set of documents: including agency agreement，declaration entrustment letter，bill of lading copy，commercial invoice，etc。to ensure "integration of four flows" (contract flow，cargo flow，capital flow，invoice flow). The new customs regulations in 2026 require that agent export customs declarations must mark the words "Agent Export" in the remarks field，otherwise they will be regarded as incomplete declaration and trigger manual review.
In addition，it is necessary to synchronously confirm the correspondence of tax refund declaration: if the declaring unit is the agent，the principal shall apply for tax refund with the Certificate of Agent Export Goods issued by the agency company，if the declaring unit is the principal，the tax refund can be processed directly with the customs declaration. It is recommended to check the document chain with a tax advisor before declaration to avoid tax refund delay.

From the perspective of customs price verification, incorrect filling of the declaring unit field may lead to price verification disputes. If the agent is the declaring unit, the customs will prioritize verifying the agent's qualification and historical declaration records; if the principal is the declaring unit, the principal is required to provide the original contract signed with the foreign buyer to prove the authenticity of the transaction. After the customs clearance integration reform in 2026, the filling of this field will directly affect cross-customs district data sharing -- incorrect filling may lead to requirements for supplementary supporting documents when the cargo is cleared at the destination port. It is recommended to verify the agent's declaration authority through the "Declaring Unit Qualification Inquiry System" of the General Administration of Customs before declaration, to ensure that the filled subject has legal qualification.

From the perspective of logistics cargo title control, the filling of the declaring unit field is closely related to bill of lading endorsement. If the declaring unit is the agent, the bill of lading needs to be endorsed and transferred by the agent to the principal or the foreign buyer; if the declaring unit is the principal, the endorsement is directly made by the principal. Incorrect filling may lead to unclear ownership of cargo title and trigger delivery disputes at the destination port. For example, some enterprises once encountered that the foreign buyer could not pick up the cargo with the bill of lading due to incorrect filling of the declaring unit, resulting in container detention charges and destination port storage fees. It is recommended to clarify the correspondence between the declaring unit and bill of lading endorsement in the logistics plan to avoid cargo title risks.

From the perspective of cross-border tax planning, the filling of the declaring unit affects VAT deferral and export tax refund efficiency. If dual-title declaration is adopted (the agent is the declaring unit), the principal can enjoy the VAT deferral policy and does not need to pay import value-added tax in advance; if it is single-title mode, the tax shall be paid according to the conventional process. The new tax regulations in 2026 require that agent export tax refund must provide supporting documents proving that the declaring unit is consistent with the operating unit, and incorrect filling will lead to rejection of the tax refund application. It is recommended to select the declaration mode based on the enterprise's tax structure. For example, small and micro enterprises can give priority to the dual-title mode to reduce capital pressure.

From the perspective of cross-border foreign exchange payment and collection compliance, the filling of the declaring unit field must be consistent with the "beneficiary" in the SWIFT message. If the declaring unit is the agent, the foreign exchange collection must first enter the agent's account, and then be transferred to the principal through compliance channels; if the declaring unit is the principal, the foreign exchange is collected directly. After the upgrade of CIPS (Cross-border Interbank Payment System) in 2026, the filling of this field will affect the speed of capital arrival -- inconsistency may trigger anti-money laundering review. It is recommended to confirm the matching between customs declaration information and the message with the bank before payment and collection, to ensure smooth capital flow.

From the perspective of legal risk, incorrect filling of the declaring unit field may lead to unclear division of rights and responsibilities in the agency agreement. If the agent is the declaring unit, the agent shall bear legal liability during the declaration process (such as inaccurate declaration); if the declaring unit is the principal, the principal shall bear the liability. It is recommended to clearly define the filling standard of the "declaring unit" and liability for breach of contract in the agency agreement. For example, if the filling error is caused by the agent's wrong guidance, the agent shall compensate for port congestion fees and declaration rejection losses. After the revision of international trade law in 2026, such clauses must be included in the core chapter of the agreement to avoid disputes.

From the perspective of on-site inspection, the filling of the declaring unit field directly affects the inspection process. If the declaring unit is the agent, the customs will require the agent's customs declarer to be present to cooperate with the inspection; if the declaring unit is the principal, the principal shall send personnel or authorize an agent to be present. Incorrect filling may lead to inspection delay and missing the sailing date. For example, some enterprises once encountered that the agent could not be present due to incorrect filling of the declaring unit, resulting in the cargo being detained in the inspection area for 3 days and incurring high container detention fees. It is recommended to confirm the qualification of the on-site personnel with the agent before inspection, to ensure that it is consistent with the declaring unit.

From the perspective of cargo packaging compliance, the filling of the declaring unit field is related to the declaration subject of MSDS (Safety Data Sheet). If the declaring unit is the agent, the MSDS must be reviewed and stamped with the official seal by the agent; if the declaring unit is the principal, the MSDS is provided by the principal. The new dangerous goods packaging regulations in 2026 require that the declaring unit shall be responsible for the compliance of the packaging -- incorrect filling may lead to seizure of dangerous goods. It is recommended to confirm the consistency between the declaring unit and the MSDS declaration subject before packaging, to avoid packaging that does not meet regulatory requirements.

From the perspective of export tax refund audit, the filling of the declaring unit field must be consistent with the tax refund declaration materials. If the declaring unit is the agent, the Certificate of Agent Export Goods issued by the agency company shall be provided for tax refund declaration; if the declaring unit is the principal, the original customs declaration and sales invoice shall be provided. The new regulations of the State Taxation Administration in 2026 require that the relevant documents linking the customs declaration and the agency agreement must be uploaded during tax refund declaration, and incorrect filling will trigger tax correspondence verification. It is recommended to check the field information of the customs declaration and the agency agreement before tax refund declaration, to ensure data consistency.

From the perspective of supply chain planning, the filling of the declaring unit field affects logistics cost and timeliness. If the dual-title mode is adopted (the agent is the declaring unit), the agent's customs AEO qualification can be used to speed up customs clearance and reduce the risk of port congestion; if it is the single-title mode, the customs clearance process needs to be handled by the enterprise itself, which may increase time cost. Under the trend of supply chain optimization in 2026, it is recommended that small and micro enterprises give priority to selecting an agent with AEO qualification as the declaring unit, so as to improve supply chain efficiency.
