I am engaged in China-Korea transshipment business. Recently I need to transship a batch of electronic products from South Korean ports to Southeast Asia. My business partner told me that a certificate of origin issued by South Korea is required, but I have no prior experience with this type of document and know nothing about the relevant procedures.
The goods are scheduled to depart on the 15th, and incorrect document preparation that leads to customs detention of goods will cause huge losses. I want to confirm the specific application process: should I apply directly at South Korean customs or through an agent? What materials are required? Will problems occur if the information on the certificate of origin does not match the bill of lading? What common pitfalls should I avoid?

The processing of certificate of origin for South Korea transshipment trade follows the full-link breakdown logic，with four key links to focus on: pre-document review，core node connection，exception contingency plan and compliance implementation.
I. Details of Pre-Document Review: In 2026，priority should be given to verifying whether the goods comply with RCEP Rules of Origin (RCEP Cumulative Rule of Origin). If the processing value-added rate of the goods in South Korea exceeds 30% (or meets the tariff classification change requirement)，the FORM K certificate (under RCEP) can be applied for. Required documents include South Korean exporter's business license，commercial invoice (with transit port noted)，packing list，logistics route proof (for example，the sea bill of lading from South Korea to the destination port must show transit port information). If the goods contain raw materials imported into South Korea，additional import customs declaration forms and certificates of origin for such raw materials are required.
II. Core Node Connection: It is recommended to submit application online via local South Korea Customs electronic port (K-ONE System)，where 11 mandatory fields including HS code of goods and transit location code need to be filled in. The system will automatically verify the consistency between declared elements and the commercial invoice. If you entrust a South Korean agent to handle the application，you need to provide a notarized agency authorization letter (with clear operable scope for the authorized person noted). Note: The certificate of origin must be issued 2 working days before the goods depart from the port to avoid certificate invalidation caused by shipping schedule delay.
III. Exception Contingency Plan: In case of declaration errors (such as HS code inconsistent with actual goods)，contact South Korea Customs immediately to submit an "amendment application"，with additional required documents including the amendment statement letter and scanned copy of the original certificate. If the transit port is not marked on the bill of lading，you can request the shipping company to issue an endorsement certificate (with the name of the transit port noted) and synchronize the update to the certificate of origin system. If on-site processing is delayed due to epidemic-related restrictions in South Korea，you can apply for the "express channel" (with an extra express fee of 500,000 KRW).
IV. Compliance Implementation: The final submitted certificate of origin must bear the certification seal of South Korea Chamber of Commerce (or the electronic seal of South Korea Customs)，and the attached commercial invoice must be fully consistent with the shipping mark information on the bill of lading. It is recommended to submit the paper version of the certificate to the destination country customs 72 hours before the goods arrive at the port，to avoid port demurrage charges caused by document circulation delays (in 2026，the free demurrage period for South Korean ports is extended to 14 days，while ports in Southeast Asia generally only have a 7-day free demurrage period).

The core requirement for South Korean certificate of origin is that the goods are substantially produced or processed in South Korea, and it is necessary to ensure that both raw material origin and processing location meet relevant rules.
If the transshipped goods contain non-South Korean originating components, relevant certificates of origin and processing value-added statements must be provided. It is recommended to use the "Rules of Origin Calculator" on the official website of South Korea Customs before application to confirm eligibility, so as to avoid subsequent goods return risks caused by misjudgment of relevant rules.。

Special attention should be paid to the logistics link: the sea bill of lading from South Korea to the destination port must clearly indicate the "transshipment port" information. If it is only marked as "export from South Korea" without showing the transit, the customs of the destination country may question the origin of the goods.
It is recommended to select direct-vessel shipping companies to avoid breakage of the goods ownership transfer chain caused by multi-stop transshipment, which increases the difficulty of certificate of origin verification.。

At the tax level, if the goods meet the RCEP VAT deferral requirements, the words "VAT exemption" must be noted on the certificate of origin, so as to enjoy temporary VAT exemption during import in South Korea (the import VAT rate is 10%).
However, the certificate of origin must be provided as the exemption basis during declaration in the destination country. Note that in 2026, all RCEP member states have simplified the VAT deferral application procedure, and only FORM K is required to be submitted at the time of import declaration.。

In the cross-border receipt and payment link, banks may require presentation of the certificate of origin as proof of authenticity for foreign exchange settlement. It is necessary to ensure that the bank account name is consistent with the applicant of the certificate of origin.
If "offshore account + CIPS RMB settlement" is adopted, confirm with the bank in advance whether the certificate of origin needs to be attached with the SWIFT message, so as to avoid dishonor caused by mismatch between settlement information and the certificate of origin consignee.。

At the legal level, if the goods are directly transshipped to a third country after processing in South Korea, make sure that the certificate of origin issued by South Korea Chamber of Commerce matches the "domestic source location" information in China's export tax rebate documents, so as to avoid verification by tax authorities caused by inconsistency of the four flows (logistics flow, capital flow, document flow, goods ownership flow). It is recommended to explicitly stipulate in the contract that losses caused by document defects shall be borne by the South Korean exporter, to reduce your own risks.。

During on-site customs inspection, customs officers may check whether the actual status of the goods is consistent with the description on the certificate of origin. For electronic products, the serial number and shipping mark need to be verified for matching. It is recommended to paste tamper-evident seals on the outer package of the goods in advance, and keep the electronic receipt generated at the time of certificate of origin issuance as the verification document, to reduce the possibility of inspection failure caused by opened packages.。

If the goods are dangerous goods (such as lithium batteries), in addition to the conventional certificate of origin, additional UN38.3 test report and MSDS are required, and the words "dangerous goods packaging complies with international standards" must be noted on the certificate of origin. The 2026 new dangerous goods packaging regulation of South Korea requires that moisture-proof and shock-proof packaging must be used, otherwise the customs may require repackaging, which delays transshipment efficiency.。

In the export tax rebate link, if the "tax rebate first, document submission later" mode is adopted, the complete certificate of origin must be supplemented within 90 days after the goods leave the territory. Overdue submission may affect the tax rebate.
It is recommended to upload the scanned copy of the certificate of origin to the tax system for pre-review in advance, to ensure that key information such as FOB price and export date on the customs declaration form are consistent, and avoid tax rebate delay caused by wrong declaration data.。
