Korea Customs Service formally opened a dedicated clearance platform for cross-border online purchases on 26 October 2026, after a pilot that began on 28 August. Overseas shopping malls, intermediaries and delivery companies can register and submit order, sales and delivery data; a new e-commerce import declaration and manifest capture the actual seller and the delivery operators; and buyers must enter their personal customs code together with a one-time number, unless the operator is certified as a cooperative recognised operator. Goods that bypass the platform or look high-risk face more X-ray and physical inspection.

Who it hits
What to prepare
- Register the company on the Korea Customs Service platform and test the transaction data feed (order, buyer, seller, product, price, quantity, payment)
- Ask for certified (cooperative recognised operator) status if you can meet the conditions: no history of personal data protection violations or misuse of customs codes, and full transaction data
- Brief customer service on the one-time number: a mismatch at clearance means the declaration is not accepted
