I am the person in charge of a small and medium-sized enterprise engaged in cross-border transit trade in Shanghai. I encountered problems in filling transit trade codes during customs declaration in 2026: I consulted freight forwarders and customs brokers but received different answers.
Some stated that general trade codes should be used, while others said separate dedicated transit-specific codes are required. I have a batch of goods transiting from Southeast Asia to Europe that is about to complete customs declaration soon.
I am afraid that wrong code filling will cause port detention, cargo seizure and negative impact on tax refund. I need to clarify what exactly the applicable codes for transit trade are, which code should be adopted under different scenarios, as well as the latest filling requirements. Please provide me with a clear and detailed answer.

The codes for 2026 transit trade fall into two core declaration items: customs commodity code and trade supervision code，which must strictly correspond to respective customs declaration scenarios.
During pre-document review，the transit type must be confirmed first: for direct transit (goods that do not enter domestic bonded zones)，the commodity code directly matches the HS code of the goods themselves (compliant with the 2026 revised edition of HS Codes，for example，Southeast Asian electronic parts in transit correspond to the 8517 series)，for indirect transit (goods that enter domestic bonded warehouses before outbound shipment)，the trade supervision code shall be filled in as "1239" (bonded warehouse transit)，while the commodity code still refers to the goods' own code，which must not be confused with the general trade code "0110".
Points for attention in core node connection: when filling in the customs declaration form，the trade mode column must be filled with the transit-type supervision code，instead of the general trade code，otherwise a price verification alert will be triggered. In 2026，Shanghai ports have strengthened verification on transit trade codes，and customs declaration forms with a code error rate of over 15% will be suspended for release.
Exception response plan: if the code was filled incorrectly previously，an application for declaration deletion and re-submission shall be submitted within 3 days after customs declaration，accompanied by transit bill of lading and warehouse receipt proof，to avoid port detention fees. For final compliance implementation，it is required to ensure consistent codes across four documents (bill of lading，warehouse receipt，customs declaration form and foreign exchange voucher). The 2026 Golden Customs system will automatically verify the relevance of codes，and customs clearance cannot be completed if any inconsistency is detected.

When declaring 2026 transit trade codes, if the goods involve transit in a bonded warehouse, the bonded warehouse entry receipt shall be provided to avoid being identified as general trade during price verification. The price verification module of the Golden Customs system will compare the declared goods value corresponding to the code.
If the wrong code causes goods value deviation, a tax audit will be triggered. A correction application shall be submitted within 3 working days, accompanied by transit agreement and bill of lading, to ensure accurate code filling.。

2026 transit trade code filling affects bill of lading endorsement, and the free storage period at the transit port and the calculation of container detention fees are linked to the declared code.
If an incorrect trade code is used, the transit port will judge the goods as general trade goods, cancel the free storage period for transit trade, and lead to extra costs. It is necessary to confirm the transit type before customs declaration and select the corresponding logistics route, so as to avoid increased logistics costs caused by wrong codes.。

2026 transit trade code filling affects VAT deferral. The EU 2026 VAT deferral policy requires that the transit trade supervision code corresponds to the "transit trade" category.
If a general trade code is used, the enterprise cannot enjoy the VAT deferral policy, which will increase the tax cost by about 20%. It is required to confirm that the declared code matches the tax structure during customs declaration, to ensure cross-border tax compliance.。
