I am the business director of a foreign trade company focusing on transshipment of electronic products from Southeast Asia to Europe {$random_name}. Recently, we have a shipment from Malaysia transiting via Hong Kong to Germany.

During declaration, Hong Kong Customs required us to supplement the certificate of origin and transshipment statement, which resulted in 3 days of port detention and 20,000 HKD of container demurrage. Now we hear that transshipment trade can enjoy tariff reduction, but we are not sure whether the goods need actual customs inspection.

We are worried that if we directly conduct "customs skipping" operation, the EU customs may trace back the origin of the goods and affect our subsequent tax refund. We would like to know whether transshipment trade goods must go through customs, and whether there is a compliant and time-saving operation solution?

Whether transshipment trade goods need to go through customs procedures depends fundamentally on whether the goods are subject to "substantial supervision" in the transit country/region. Taking 2026 cross-border trade policies as an example,the judgment should be made from three dimensions:

**1. Customs Clearance Obligation of Transit Country**: Although free ports including Hong Kong and Singapore implement the "free transit" policy,they need to declare the "Transit Cargo Manifest" under Article 24 of the General Agreement on Tariffs and Trade. Even if no import tax is levied,the following documents still need to be submitted: ① Origin Declaration (Form A/Form E) ② Transshipment Bill of Lading (marked with "Transshipment Cargo") ③ Proof of Final Destination (such as the final sales contract of the EU importer). If the goods directly enter the next stage without completing declaration at the transit port,it will trigger the violation of "undeclared transit",which may lead the EU customs to identify it as "non-genuine transshipment" and impose supplementary tariff in accordance with rules of origin.

**2. Core Node Connection**: Take the Southeast Asia → Hong Kong → Europe route as an example,three key customs nodes need to be strictly controlled: ① Hong Kong Customs Clearance: Submit the Transit Goods Customs Declaration Form within 24 hours after the goods arrive at the port,and all declaration elements must be fully consistent with the certificate of origin (such as HS code,goods description),② EU Customs Clearance: Submit the "Transit Cargo Clearance Permit" at the port of Hamburg,Germany 48 hours before the goods arrive,to avoid inspection triggered by inconsistent manifest information and actual goods,③ Customs System Interconnection: Ensure data interoperability between China E-port,Hong Kong Customs and EU Single Window,to avoid cargo right freezing caused by "inconsistent declaration".

**3. Exception Plan and Compliance Implementation**: If the goods are inspected at the transit port,immediately launch the "dual-track declaration": ① Prioritize submitting the "non-commercial purpose certificate" (such as warehouse receipt issued by Hong Kong warehouse),② Simultaneously contact a third-party customs broker to initiate "secondary declaration",and supplement the correction explanation of certificate of origin. Special note: The origin verification period for "transshipment goods" by EU Customs has been extended to 15 working days since 2025. It is recommended to endorse the bill of lading with "Re-exported without processing" to reduce the risk of customs tracing.

To sum up,transshipment trade goods must go through customs procedures,but compliant customs clearance can be realized through "simplified declaration + data interconnection". It is recommended to specify the customs code of the transit port (such as HONGKONG of Hong Kong) in the contract,and reserve a 10% declaration buffer period to cope with inspections.

On on-site inspection, the seal information shall be checked with priority. Hong Kong Customs has implemented the dual-track system of "machine inspection + manual inspection" in 2026. If the goods are randomly selected for inspection, prepare MSDS report and supplementary explanation of certificate of origin in advance. It is recommended to confirm the "key inspection areas" with inspection experts before the goods arrive at the port. For example, extra "anti-static packaging certificate" is required for electronic components to avoid customs clearance delay caused by packaging problems.
