I am the person in charge of a small and medium-sized enterprise engaged in precision instrument export. I have just received an order for goods to be shipped to Germany, and this is my first time entrusting an agent to handle export customs declaration. I heard from peers before that unclear process formulation led to a one-week port detention of goods and extra costs, which makes me very worried. I currently have the contract, invoice and packing list on hand, but I do not know how to sort out the specific process of proxy customs declaration.

For example, what materials should I provide to the agent first? How should I mark the time nodes of each link? If there is a problem with customs document review, what response measures should be added to the process? I hope to get detailed guidance to avoid pitfalls.

First of all，pre-document review is the foundation of the process. It is necessary to ensure that the core information on the customs declaration form provided by the agent is completely consistent with that on the commercial invoice and packing list，especially HS Code，quantity，weight and cargo value. Special attention shall be paid to the newly issued "Precision Instrument Classification Guidelines" by the customs in 2026，to avoid document review delay caused by coding errors.

Second，a clear timeline shall be specified for the connection of core nodes. The first step is to entrust the agent and submit a full set of documents (T+0)，the second step is for the agent to pre-enter the customs declaration form and give feedback for confirmation (T+1)，the third step is customs document review (T+1 to T+2)，the fourth step is to arrange shipment after release (T+2 to T+3). It is required to track customs receipts in real time to ensure seamless connection of each node.

Third，exception response plans are indispensable. In case of customs document review suspension，you shall immediately ask the agent to provide the reason for the suspension，if materials are incomplete，supplementary materials shall be submitted within 24 hours，if there is a coding dispute，you need to prepare product specifications and technical parameter certificates，and submit them to the customs for price consultation within 48 hours.

Finally，compliance implementation requires archiving for future reference. After customs clearance，customs declaration forms，release notices and logistics documents shall be kept for at least 5 years，complying with the latest customs requirements on document retention in 2026. Meanwhile，check the expense details provided by the agent to ensure no hidden charges.

In the proxy export customs declaration process, the price review link is a key risk point. The customs adopts the "big data comparison" mechanism for price review in 2026. If the declared unit price deviates from the recent declared price of commodities of the same category by more than 15%, manual document review will be triggered.

Therefore, the "pre-price review check" step shall be added to the process: ask the agent to provide the recent price review range for commodities under the same HS Code in advance, to ensure the declared price is within a reasonable range. In case of price review disputes, prepare the procurement contract, payment vouchers and cost accounting sheets, and submit them to the customs for price consultation within 48 hours.。

The connection between logistics nodes and customs declaration shall be clarified in the process. For example, when booking space, inform the freight forwarder of the information of the customs declaration agent, to ensure the manifest data is consistent with the customs declaration form.

In case of container rolling, immediately notify the agent to modify the vessel name and voyage number on the customs declaration form, to avoid cargo seizure caused by manifest inconsistency. In addition, mark the free storage period and the starting point of demurrage calculation in the process, and it is recommended to reserve a 3-day buffer period to reduce the risk of extra expenses.。

The application of VAT deferral shall be considered in the proxy export customs declaration process. Some EU countries still support import VAT deferral in 2026.

If the goods are shipped to Germany, the "VAT deferral application" step can be added to the process: entrust the agent to submit the deferral application to the customs, and the EORI number and German tax registration certificate shall be provided. This measure can reduce capital occupation, and the application time node (1 day before customs declaration) and required materials shall be clarified in the process.。

The "packaging inspection" step shall be clarified in the process: entrust a third-party institution to test the packaging to ensure it meets ISTA standards.
