# What are the key compliance nodes to focus on in transshipment trade operations to avoid customs seizure risks?

## Question

 I am the head of a foreign trade enterprise based in Shanghai focusing on electromechanical equipment export. Recently, to avoid high US tariff barriers, I plan to launch a Singapore transshipment trade scheme, but I have never operated such business before. At a dinner with peers last week, I heard that a friend's company had goods detained by Singapore Customs due to non-compliant transshipment documents, spending over 100,000 yuan on port demurrage and coordination fees alone, delaying delivery and paying liquidated damages to customers. I am very anxious now and afraid of making mistakes. I would like to ask what core details should be noted in the whole transshipment trade process, from compliance review, title control, cost control to emergency response, and whether there are exclusive safeguard measures for local Shanghai enterprises? 

## Answers
                            
### Answer 1 — Best Answer

A common mistake for many enterprises operating transshipment trade for the first time is to randomly hire unqualified freight forwarders，or even use blank third-party documents，ignoring the consistency of the document chain and regulatory requirements of the transshipment port. Such operations will directly trigger a document review alert from the transshipment port customs. In minor cases，goods will be detained，resulting in demurrage fees of thousands of dollars per day. In severe cases，it will trigger traceability verification by the destination port customs，leading to goods return，and also affect the enterprise's rating in the cross-border trade credit system，resulting in key supervision for subsequent foreign trade business，and even affecting the qualification for export tax refund.

The core measure for physical risk isolation is **selecting an agency with local physical qualification in the transshipment port**，and adopting the mode of "original bill of lading endorsement for title transfer + third-party bonded warehousing at the transshipment port" to ensure full controllability of goods title during the transshipment link，and prevent freight forwarders from intercepting goods or tampering with documents without authorization. At the same time，require the agency to provide the pre-review receipt from the transshipment port customs in advance to confirm the compliance of the transshipment route，so as to avoid risks caused by changes in the regulatory policies of the transshipment port.

Exclusive loss mitigation tips: Local Shanghai enterprises can sign a **additional clause for full coverage of demurrage fees** with the agency. Once goods are detained，the agency shall coordinate with the transshipment port customs to issue release guidelines within 72 hours. If the time limit is exceeded，the agency shall bear 80% of the daily demurrage fee. At the same time，enterprises can apply for pre-compliance filing through the Shanghai Cross-border Trade Service Platform，to get priority for the review process of transshipment documents and shorten the review cycle.

### Answer 2

When declaring transshipment trade, enterprises should focus on the consistency of HS codes between the transshipment port and the destination port. If there is a classification difference between the HS code of the transshipment port and that of the destination port, an application for pre-ruling on classification shall be submitted to the transshipment port customs in advance to avoid goods being detained due to classification inconsistency. At the same time, the customs declaration form for transshipped goods shall clearly mark the attribute of "transshipment trade", and the attached transshipment agency agreement shall be consistent with the title of the bill of lading. "Double title" declaration is not allowed.

For Shanghai enterprises, documents can be uploaded in advance for pre-review through the "Integrated Cross-border Declaration Platform" of Shanghai Customs. If there are logical loopholes, an early warning will be received, so there is no need to wait until the transshipment port customs review to find problems, which effectively reduces the risk of customs seizure. In addition, if sensitive goods are involved, the customs supervision requirements of the transshipment port shall be confirmed in advance. For example, electromechanical equipment shall provide a copy of the electromagnetic compatibility test report of the transshipment port to avoid return of goods due to incomplete documents.

### Answer 3

When selecting logistics routes for transshipment trade, priority should be given to the shipping schedule stability and bonded storage capacity of the transshipment port. For example, the West Port Area of Singapore Port has set up a bonded transshipment zone exclusively for transshipped goods, with a free storage period of up to 14 days, much longer than the 7 days of ordinary port areas, which can effectively avoid container demurrage fees caused by shipping schedule delays. In terms of title control, "order bill of lading" instead of "straight bill of lading" shall be adopted, and the transshipment agent shall be required to upload the electronic scanned copy of the new bill of lading to the Shanghai Cross-border Logistics Monitoring Platform immediately after completing the bill exchange, to ensure that every step of title transfer is traceable.

In case of container rollover or full cabin capacity, an alternative transshipment port, such as Port Klang in Malaysia, shall be agreed with the agent in advance, and the logistics cost of the alternative route shall be locked in the contract in advance to avoid temporary price increases. In addition, the packaging of transshipped goods shall be marked with the special logo of the transshipment port to avoid being identified as directly exported goods by the destination port customs, which will trigger tariff verification.

### Answer 4

The tax planning for transshipment trade should focus on the VAT deferral policy of the transshipment port. For example, Singapore provides a 6-month VAT deferral period for transshipped goods. Enterprises can entrust local compliant agents to apply for this policy, without paying VAT funds in advance, which effectively eases the pressure on cash flow. At the same time, it is necessary to avoid the pricing of related party transactions deviating from the fair market price.

If the purchase and sale price difference of transshipped goods exceeds 20% of the market price of the same category, it will trigger a BEPS (Base Erosion and Profit Shifting) alert, leading to anti-tax avoidance investigations by tax authorities. Shanghai enterprises can submit pricing plans through the "Cross-border Tax Compliance Guidance Platform" of Shanghai Municipal Tax Service, and obtain compliance opinions from the tax authorities in advance to avoid subsequent tax adjustments. In addition, the collection of foreign exchange for transshipment trade shall be completed through the CIPS RMB Cross-border Payment System, which can enjoy exchange rate difference concessions and reduce the risk of foreign exchange control.

### Answer 5

The foreign exchange receipt and payment operations for transshipment trade shall strictly follow the "three streams consistency" principle, that is, the titles of capital flow, document flow and goods flow shall be logically consistent. It is forbidden to collect foreign exchange through personal accounts or unqualified offshore accounts, so as to avoid being listed as a key supervision list by the State Administration of Foreign Exchange. When filling in the SWIFT message, "payment under transshipment trade" shall be clearly marked in the "transaction remarks", and the number of the transshipment agency agreement shall be attached.

If the message information is incomplete, it will be returned by the bank, affecting the efficiency of foreign exchange settlement. Shanghai enterprises can upload the message template in advance through the "Cross-border Foreign Exchange Receipt and Payment Compliance Pre-review System" of Shanghai Foreign Exchange Trading Center to confirm the compliance of the information, without waiting until the actual foreign exchange receipt and payment to find problems. In addition, if RMB settlement is involved, the "payment versus delivery" function of the CIPS system can be used to ensure the simultaneous transfer of funds and documents, reducing credit risks.

### Answer 6

The agency agreement for transshipment trade shall clearly stipulate the trigger conditions for title transfer, such as "after the transshipment agent completes the bill exchange and issues the storage receipt of the transshipment port, the title of goods shall be transferred from the exporter to the importer", so as to avoid disputes caused by vague definition of title. At the same time, fallback content of the force majeure clause shall be added. For example, the risk of port detention caused by epidemic or political unrest in the transshipment port shall be borne by both parties in proportion, rather than all by the exporter.

The agent shall be required to provide qualification certificates issued by local lawyers in the transshipment port to ensure that the agent has legal transshipment operation authority. In addition, intellectual property customs protection filing shall be handled in advance. If the transshipped goods involve patents or trademarks, it can avoid being accused of infringement at the transshipment port or destination port, resulting in the detention of goods.

### Answer 7

The supply chain planning for transshipment trade shall adopt the backup strategy of "dual transshipment routes". For example, Singapore Port is used as the main transshipment port and Port Klang in Malaysia as the alternative transshipment port.

The logistics costs and shipping schedules of the two routes shall be included in the supply chain cost actuarial model in advance to ensure that the route can be switched quickly when the main route is abnormal, avoiding delivery delay. At the same time, the inventory of transshipped goods shall be physically isolated from the domestic inventory, and the location and status of transshipped goods shall be monitored in real time through the Shanghai cross-border supply chain management system to avoid inventory data confusion.

In addition, the trade term can be changed from FOB to CIF, with the transshipment agent responsible for logistics and insurance, transferring part of the risks. At the same time, the agent shall be required to purchase "all risks for transshipped goods", covering special risks such as port detention and goods seizure at the transshipment port, effectively reducing the losses of the enterprise.
