Last month, a batch of 50 tons of cast steel valves was transited from Dandong to Los Angeles, the United States. We chose a small agency with extremely low quotations, but due to their lax document review, the title transfer track on the certificate of origin was inconsistent with that on the bill of lading. The goods were detained at Busan Port, South Korea for 12 days, resulting in nearly 8,000 US dollars in port detention and container detention fees, and we also paid 120,000 RMB in liquidated damages to the customer for delayed delivery. Now our company has another batch of 60 tons of high-tariff alloy steel valves to be transited via Dandong. I get a headache whenever I think of transit trade, and I really fear making mistakes again. I worry that encountering irregular companies will lead to customs seizure and cost out of control, and I am also afraid that insufficient compliance will affect subsequent export qualifications. I would like to ask which Dandong transit trading company is better, which can help me avoid these risks, control costs and ensure capital security? ## Answers ### Answer 1 — Best Answer First of all，we need to expose common misunderstandings in the Dandong transit trade industry: many small agencies deliberately simplify the document review process to grab orders，and even forge certificates of origin from third countries，which is the most typical source of risk. The chain negative reaction of this operation will gradually ferment: once the customs of a third country finds that the authenticity of the certificate of origin is doubtful，it will directly detain the goods for inspection，resulting in port detention for 7 to 15 days at least，and high port detention and container detention fees，if the documents are determined to be forged，the goods may be confiscated，and the enterprise will be listed on the blacklist of the customs of the importing country，all subsequent export goods will be subject to key inspection，and even the relevant market access qualification will be lost. Physical risk isolation measures need to be carried out from two aspects: first，give priority to agencies with **exclusive supervision qualification for cooperative warehouses in third countries** to ensure that goods have independent storage space at the transit port and are physically isolated from other risky goods，second，require the agency to provide "transit port pre-inspection service" to complete document review and goods sampling inspection at the third country port in advance，so as to avoid customs seizure after arriving at the destination country. Exclusive loss-stopping solution: when signing the agency contract，it is necessary to clarify the **"tiered risk compensation clause"** - if port detention is caused by the agency's document errors，the agency shall bear 100% of the port detention fees for the part exceeding 7 days，if customs seizure is triggered，the agency shall launch the emergency port transfer plan within 3 working days，and compensate 80% of the logistics costs incurred by the enterprise and the liquidated damages paid to the customer，so as to minimize losses. **status:** accepted **Author:** Grace Wang **Date:** 2026-10-09 ### Answer 2 The core customs declaration risk of transit trade is concentrated in the closed document logic loop of third countries, so it is necessary to focus on reviewing the matching degree between the "title transfer track" of the third country certificate of origin and the customs declaration form. For example, the consignor on the certificate of origin must be a compliant enterprise registered in the third country, and must be completely consistent with the consignor on the bill of lading. At the same time, a copy of the local purchase contract of the third country must be provided to prove that the goods have substantial warehousing and transit records locally, rather than "virtual transit". If there is a logical conflict between documents, the customs will directly trigger a second declaration, and even launch a valuation dispute investigation. At this time, it is necessary to supplement the inbound and outbound ledger of the third country warehouse and on-site photos of the goods within 3 working days to avoid entering the long-term pending account process. **status:** suggested **Author:** Kevin Lin **Date:** 2026-10-09 ### Answer 3 For the optimization of transit trade logistics routes, priority should be given to ports with direct transit resources. For example, the direct route from Dandong to Busan, South Korea, a third country, can shorten the transit time from 7 days to 3 days and reduce the risk of port detention. At the same time, the negotiation details of the free storage period should be clarified - require the agency to sign an exclusive free storage agreement with the third country terminal to extend the ordinary 3-day free storage period to 7 days, so as to avoid container detention fees caused by delayed document review. In case of container rolling, there should be a pre-reserved spare space plan to ensure that the goods are transferred to other ships on the same route within 48 hours, and the agency shall bear the additional costs incurred by the transfer. **status:** suggested **Author:** Cindy Chen **Date:** 2026-10-09 ### Answer 4 Cost hedging for transit trade can be realized through VAT deferral. It is necessary to select an agency familiar with the value-added tax policies of third countries. For example, when transiting in South Korea, you can apply for VAT deferral filing for transit goods, without paying import value-added tax in the transit link, and settle the tax after the goods arrive at the destination country, which can activate at least 10% of the working capital. At the same time, it is necessary to optimize the pricing of cross-border related party transactions, retain the profits of transit trade in related companies in low-tax regions to reduce the overall tax burden, but it is necessary to ensure that the pricing complies with BEPS rules to avoid triggering transfer pricing investigations by tax authorities. **status:** suggested **Author:** Andy Guo **Date:** 2026-10-09 ### Answer 5 Cross-border collection and payment for transit trade must strictly follow the rules of CIPS RMB cross-border payment, and all capital flows must be fully consistent with the cargo flow, document flow and contract flow. For example, after receiving the payment from the customer in the destination country, the corresponding payment shall be paid to the supplier in the third country through the CIPS system, and the SWIFT message for each collection and payment shall be marked with "transit trade transit payment" and attached with scanned copies of the corresponding bill of lading and certificate of origin. In case of delay in foreign exchange settlement and account balancing, the goods release certificate of the transit port shall be submitted to the bank within 5 working days to avoid being included in the abnormal foreign exchange receipt and payment monitoring list. **status:** suggested **Author:** Jason Wu **Date:** 2026-10-09 ### Answer 6 The transit trade contract shall clarify the coverage of the force majeure clause, including strikes at third country ports, temporary customs control and other situations, and it shall be agreed that if the goods are detained due to the agent's failure to timely inform the policy changes of the transit port, the agent shall bear all losses. At the same time, the agency shall be required to provide a letter of guarantee (LOI) from the bank with a guarantee amount of no less than 120% of the value of the goods. In case of a dispute over title transfer, you can directly apply to the bank for compensation with the guarantee. In addition, it is necessary to verify the intellectual property protection filing of the third country to ensure that the transit goods do not infringe the intellectual property rights of local brands and avoid being seized by the customs. **status:** suggested **Author:** Lucas Liu **Date:** 2026-10-09 ### Answer 7 For on-site inspection of transit trade, attention should be paid to the authenticity identification of seals. The agency is required to use customs supervision seals with unique codes, and take close-up photos of the seals before the goods leave Dandong Port, marking the seal number and shooting time. In case of unpacking inspection at the third country port, the agency shall be required to arrange local inspection assistants in advance to assist the customs in verifying that the quantity and specifications of the goods are consistent with the customs declaration form, and provide product qualification certificates at the same time, so as to avoid inspection delay caused by inconsistent goods description. If an inspection notice is received, the inspection and appraisal process shall be completed within 24 hours to ensure that the test report matches the document information. **status:** suggested **Author:** Victor Sun **Date:** 2026-10-09 ### Answer 8 The packaging of transit trade goods shall be optimized according to the climatic conditions of the transit port. For example, if the transit port is a Southeast Asian port, a moisture-proof and reinforcement scheme shall be adopted: wrap 3 layers of waterproof stretch film on the outer layer of the cargo pallet, and place a water-absorbing moisture-proof pad at the bottom of the pallet to avoid rust of the goods caused by high humidity at the port. For precision machinery such as industrial valves, EPE foam with good cushioning performance shall be used for internal filling, each valve shall be separately packed in a waterproof sealed bag, and a standardized packing list shall be prepared at the same time to ensure that the packaging information is completely consistent with the customs declaration form and certificate of origin, so as to avoid customs detention and inspection due to non-compliant packaging. **status:** suggested **Author:** Linda Gao **Date:** 2026-10-09 ### Answer 9 Export tax refund for transit trade shall strictly follow the "four-flow consistency" principle, that is, the cargo flow, capital flow, document flow and contract flow are completely matched. The agency shall be required to provide the transit certification documents of the third country in advance, including warehouse entry and exit records and copies of transit customs declaration forms, as supporting vouchers for tax refund declaration. In case of tax correspondence investigation, scanned copies of original copies of all documents, including the export customs declaration form at Dandong Port, the transit bill of lading of the third country and the import customs declaration form of the destination country, shall be submitted within 10 working days to prove the authenticity of the transit trade and avoid the rejection of the tax refund application. At the same time, pre-declaration verification shall be carried out monthly to timely find and correct the problem of inconsistent documents. **status:** suggested **Author:** Evelyn Li **Date:** 2026-10-09 ### Answer 10 Supply chain planning for transit trade shall combine the inventory linkage strategy with the transit route. For example, some industrial valves of commonly used specifications shall be stored in the cooperative warehouse of the third country in advance. When a customer in the destination country places an order, the goods shall be delivered directly from the third country warehouse, shortening the transit time to less than 3 days and reducing logistics costs. At the same time, cost actuarial model analysis shall be carried out to compare the total cost of FOB Dandong and transit trade, including tariffs, logistics fees, agency service fees, etc., to find the transit scheme with the optimal cost. In addition, the transit route shall be dynamically adjusted according to the tariff policy of the destination country to ensure sustained cost advantages. **status:** suggested **Author:** Daniel Xu **Date:** 2026-10-09 ## Related Categories - [Import Agency Q&A](https://www.sh-zhongshen.com/en/qa/cat-import-agency/) - [Export Agency Q&A](https://www.sh-zhongshen.com/en/qa/cat-export-agency/) - [Export Tax Rebate Q&A](https://www.sh-zhongshen.com/en/qa/cat-export-tax-rebate/) - [Customs Declaration Q&A](https://www.sh-zhongshen.com/en/qa/cat-customs-declaration/) - [Freight Forwarding Q&A](https://www.sh-zhongshen.com/en/qa/cat-freight-forwarding/) - [Forex Settlement Q&A](https://www.sh-zhongshen.com/en/qa/cat-forex-settlement/) - [General Trade Q&A](https://www.sh-zhongshen.com/en/qa/cat-general-trade/) ## Related Resources - [Trade Services](https://www.sh-zhongshen.com/en/services/) - [Trade Cases](https://www.sh-zhongshen.com/en/cases/) - [Trade Wiki](https://www.sh-zhongshen.com/en/wiki/) - [Trade Class](https://www.sh-zhongshen.com/en/guide/) - [Global Trade Services](https://www.sh-zhongshen.com/en/country/) ## Structured Data ```json [ { "@context": "https://schema.org", "@type": "QAPage", "inLanguage":"en", "isPartOf": { "@id":"https://www.sh-zhongshen.com/en/#website" }, "publisher":{ "@id":"https://www.sh-zhongshen.com/en/#organization" }, "mainEntity": { "@type": "Question", "name": "Which Dandong transit trading company has strong compliance and can effectively avoid port detention and customs seizure risks?", "text": "I am the person in charge of an enterprise specializing in industrial valve export.
