I am a foreign trade salesperson specializing in outdoor furniture exports, with main markets in Europe and America. This year, a 25% tariff has been imposed on our products. I previously learned that Korean transshipment can avoid tariffs, but I am completely unfamiliar with local Korean transshipment companies. I am now very worried about how to choose the right one, fearing that unqualified companies may lead to customs detention due to document discrepancies or loss of cargo ownership.
Additionally, I want to know if there are any new compliance requirements from Korean Customs for transshipment trade in 2026, such as requirements for transit warehouse registration and documents, and whether these companies have hidden charges. I need a company that can provide end-to-end services from domestic shipment to Korean transshipment and then to customs clearance in Europe and America. Can you help me sort this out?

The first step to select a Korean transshipment company is to verify its compliance qualifications. In 2026，Korean Customs updated the registration requirements for transshipment trade. All legitimate transshipment companies must complete registration with the Korea Trade-Investment Promotion Agency (KOTRA) and possess the China-Korea Customs AEO Mutual Recognition Qualification. This can be checked through the public database on the Korean Customs official website to avoid choosing unregistered "shell companies".
The second point is to check the end-to-end service capability. A reliable company should cover the entire process from domestic cargo warehousing，Korean transshipment storage，container replacement and labeling，document preparation to customs clearance in Europe and America. Special attention should be paid to whether it has its own local warehouse in Korea to avoid loss of cargo ownership due to third-party subcontracting. In 2026，Korean Customs added the real-time synchronization requirement for electronic manifests. Legitimate companies must be able to connect to the customs electronic systems of both China and Korea to avoid detention penalties caused by manifest data discrepancies.
The third point is to verify tax compliance capability. The core of Korean transshipment is to avoid tariffs，so the company must provide reasonable transshipment documents，including compliant application for Korean Certificate of Origin and tax structure design to avoid BEPS (Base Erosion and Profit Shifting). In 2026，the Korean Tax Office strengthened tax audits for transshipment trade，requiring companies to provide complete cargo ownership transfer certificates and transaction vouchers to avoid being identified as related-party transactions and incurring additional taxes.
The fourth point is to understand the fee model. Legitimate companies usually charge logistics fees，storage fees，document fees，and service fees with no hidden costs. You need to request a detailed quotation in advance to confirm whether it includes the duration of free storage period and free container use period，as well as handling fees for abnormal situations such as port changes and port detention，to avoid additional expenses later.
Finally，it is recommended to ask the other party to provide 3-5 past transshipment cases of the same category of goods and feedback from cooperative customers (with their consent) before cooperation. At the same time，sign a detailed cargo ownership guarantee agreement to clarify the ownership of cargo and liability for breach of contract，ensuring the entire transshipment trade process is compliant and controllable.

In 2026, Korean Customs further tightened the document review standards for transshipment trade, with the primary check being the authenticity of transshipment storage. Legitimate operations require providing entry and exit certificates of Korean bonded warehouses, as well as photos or surveillance videos of the container replacement process to prove that the goods have indeed undergone substantive transshipment in Korea, not just document flow. For the price assessment link, Korean Customs will compare the origin price of the goods with the declared price after transshipment.
If the price difference exceeds 15%, further verification will be initiated. At this time, complete cargo ownership transfer certificates are required, including the purchase contract between the domestic supplier and the Korean transshipment party, the sales contract between the Korean transshipment party and the European/American buyer, and corresponding logistics documents to prove the authenticity of the transaction. In addition, China-Korea AEO mutual recognition enterprises can enjoy customs clearance priority and pass customs inspection first. Therefore, prioritizing transshipment companies with this qualification can significantly reduce the risk of detention.

The choice of logistics route for Korean transshipment trade needs to be adjusted based on the type of goods and the destination in Europe and America. Busan Port, as Korea's largest container hub port, has transshipment routes covering more than 100 countries worldwide, with a maximum free storage period of 14 days, making it the first choice for most transshipment businesses. Incheon Port is closer to Seoul and suitable for transshipment of small batches of high-value goods.
The container replacement process must be completed in a bonded warehouse recognized by Korean Customs. Legitimate transshipment companies need to have their own or long-term cooperative bonded warehouses to avoid process delays caused by temporary rentals. The bill of lading operation should adopt the "transshipment bill of lading" model, where the Korean transshipment party issues the bill of lading as the first carrier.
The domestic shipper needs to endorse the bill of lading to the Korean transshipment party, which then endorses it to the European/American buyer to ensure the compliance of cargo ownership flow. At the same time, the duration of the free container use period should be confirmed in advance to the longest free storage and container use periods, avoiding hidden expenses such as container detention fees and port detention fees.

In 2026, the Korean Tax Office increased the intensity of tax audits for transshipment trade, focusing on BEPS (Base Erosion and Profit Shifting) risks. First, it is necessary to ensure that there is no related-party relationship between the Korean transshipment party and the domestic shipper. If they are related enterprises, reasonable pricing proof must be provided to show that the transshipment price is in line with the fair market level to avoid being identified as a related-party transaction.
Korea's VAT rate is 10%, and transshipment trade can apply for VAT deferral, meaning that VAT is paid when the goods leave Korean territory. A VAT deferral application must be submitted to Korean Customs in advance, providing materials such as the transshipment contract and cargo ownership certificate.
In addition, if the domestic shipper receives service fees through the Korean transshipment party, it needs to pay a 10% withholding tax in accordance with Korean non-resident enterprise withholding tax regulations. Some taxes can be avoided by signing tax agreements, but tax registration must be completed in advance. All tax documents must be retained for at least 5 years for inspection by the Korean Tax Office.

Cross-border payment and receipt for transshipment trade must strictly follow the foreign exchange management regulations of both China and Korea. The domestic shipper must receive payment from European/American buyers through formal bank channels and then pay the transshipment service fee to the Korean transshipment party, using corporate accounts throughout and strictly prohibiting the use of personal accounts for payment and receipt.
In the settlement link, forward exchange settlement products can be used to lock the exchange rate and avoid exchange rate fluctuation risks. In 2026, the State Administration of Foreign Exchange of China allows transshipment trade enterprises to use the CIPS (Cross-Border Interbank Payment System) for RMB cross-border payments and receipts without relying on the SWIFT system, improving settlement efficiency.
It should be noted that all payment and receipt documents must be consistent with trade contracts, bills of lading, packing lists, etc., i.e., "consistency of four flows" (goods flow, capital flow, document flow, contract flow). Otherwise, it will be identified as an illegal operation by the foreign exchange management department. In addition, foreign exchange receipt verification must be completed within 30 days after the goods actually leave the country to avoid affecting subsequent payment and receipt operations.

The legal risks of transshipment trade mainly focus on cargo ownership protection and contract terms. When signing a transshipment contract, it is necessary to clarify the cargo ownership clause, stipulating that the ownership of the goods during transshipment in Korea belongs to the domestic shipper until the goods are delivered to the European/American buyer.
The bill of lading should be an order bill of lading rather than a straight bill of lading to ensure that the cargo ownership can be transferred by endorsement. At the same time, a force majeure clause should be included to clarify the division of responsibility for delays caused by force majeure factors such as Korean Customs inspection and port strikes.
For letters of credit from European/American buyers, soft clauses should be carefully reviewed to avoid vague requirements such as "need to provide a transshipment certificate issued by Korean Customs". If it cannot be met, it is necessary to negotiate with the buyer in advance to modify it. In addition, a bank guarantee should be used as payment security to ensure that the Korean transshipment party can receive full payment after completing the transshipment service, while ensuring the cargo ownership safety of the domestic shipper.

Korean Customs' on-site inspection mainly focuses on the authenticity and compliance of transshipment goods, with core checks on seals and the consistency between goods and documents. First, it is necessary to ensure the use of seals recognized by Korean Customs, and the seal number must be consistent with the manifest information. If the seal is damaged, it is necessary to report to Korean Customs immediately and apply for a new seal.
Before container inspection, the cargo list should be sorted in advance, and the goods listed in the documents should be placed at the container door for easy verification by inspectors. When passing through the machine inspection, the goods should be placed reasonably to avoid machine inspection alarms caused by high-density cargo stacking.
If there is an abnormality in the machine inspection, it is necessary to cooperate with the inspectors for container inspection. If the goods are sent for inspection, a test report meeting Korean standards must be provided within 24 hours, otherwise the goods will be detained. In 2026, the inspection rate of Korean Customs increased by 20% compared to last year, so all documents and cargo certificates must be prepared in advance to avoid delays.

The packaging for Korean transshipment trade must comply with the transportation standards of both China and Korea and the inspection requirements of Korean Customs. Large goods such as outdoor furniture need to be packaged with wooden pallets, which must undergo fumigation treatment and issue an IPPC fumigation certificate, otherwise Korean Customs will refuse entry. The packaging must have moisture-proof and shock-proof functions, and buffer materials such as bubble film and foam boards can be used to wrap the goods to avoid damage during transportation.
If the goods are metal products, additional anti-rust paint must be applied to prevent rusting due to moisture during sea transportation. In the labeling link, according to Korean Customs requirements, labels with information such as goods name, quantity, origin, and HS code should be affixed to the outside of the packaging, and the labels must be in Korean or English. In 2026, Korean Customs added environmental protection requirements for packaging materials, prohibiting the use of packaging materials containing Freon. It is necessary to confirm the environmental certification of packaging materials in advance to avoid cargo detention due to packaging violations.

Export tax rebates for transshipment trade must strictly follow the relevant regulations of the State Taxation Administration of China. According to the latest policy in 2026, if transshipment trade goods do not actually leave China, export tax rebates cannot be applied for.
If the goods actually leave for Europe and America after transshipment in Korea, the "consistency of four flows" requirement must be met, i.e., the goods flow, capital flow, document flow, and contract flow are completely consistent. Specifically, it is necessary to provide the purchase contract between the domestic supplier and the domestic shipper, the transshipment contract between the domestic shipper and the Korean transshipment party, the sales contract between the Korean transshipment party and the European/American buyer, as well as corresponding logistics documents, payment/receipt documents, bills of lading, etc. In addition, the tax rebate declaration must be completed within 90 days after the goods actually leave the country.
If the deadline is exceeded, an extension must be applied for from the tax department. During the tax letter verification link, it is necessary to cooperate with the Korean Tax Office's inspection and provide complete transaction documents and cargo ownership certificates to avoid being identified as defrauding export tax rebates.
