What to do when your overseas shipment gets stuck in customs

Checking your package status via Uni-Pass

When a package from an overseas direct purchase is delayed, the first step is to stop refreshing your shopping app and head straight to the Korea Customs Service’s Uni-Pass website. Tracking numbers provided by platforms like Temu or AliExpress often stop updating once the package reaches the domestic entry point. By entering your Master B/L number—which you can find in your order details or the courier’s notification—you can see if the package is in ‘Entry Declared’ status or if it has been moved to ‘Customs Inspection.’ If the status has been stuck on ‘Import Inspection’ for more than 48 hours, it usually indicates that the customs broker is waiting for additional information or that the shipment has been flagged for a random scan.

Understanding the customs inspection process

It is common for shipments to be held for inspection without prior notice. This often happens because the cargo manifest provided by the shipping agent is incomplete or mismatched with the physical contents. In many cases, you don’t need to do anything; the customs office or the contracted customs brokerage firm will handle the verification process internally. However, if the package remains in a ‘Hold’ or ‘Suspended’ status for more than five business days, it is time to take action. You can identify the customs brokerage firm responsible for your package by checking the contact information linked to your tracking number on the Uni-Pass portal.

Communicating with customs brokerage firms

When you call a customs brokerage firm, have your personal customs clearance code (PCCC) and tracking number ready. They often receive high volumes of inquiries, so be specific about why you are calling. Sometimes, the issue is as simple as a missing phone number or a duplicate address entry in their system, which prevents them from generating the final clearance notification. If the hold is due to an underestimated value of the goods, they may ask for a screenshot of your purchase history or a credit card statement. Expect to be asked to send this via email or fax, as they rarely accept documents through casual messaging apps.

Managing realistic delivery timelines

One thing to keep in mind is that the stated shipping estimates on international marketplaces are often optimistic. Even after a package clears customs, it typically takes another 2 to 3 days to transfer from the bonded warehouse to a local courier like CJ Logistics or Lotte Global Logistics. During peak shopping seasons or public holidays, the customs backlog can extend these processing times significantly. If you see a notification that your package is ‘in transit’ but hasn’t moved for several days, it is frequently just sitting in a regional hub waiting for a truck space, which is a common logistics bottleneck rather than an issue with your specific order.

Factors that trigger unexpected delays

Certain items are more prone to scrutiny than others, which can lead to longer hold times. Food items, herbal supplements, and electronic devices often require additional documentation regarding ingredients or electrical safety certifications. If you are importing items that exceed the typical duty-free allowance—which is currently $150 for general goods—you will receive a notification from the customs broker requesting payment for the duty and VAT. It is usually best to pay this promptly via the provided virtual account, as packages are often released for delivery within a few hours of the payment being confirmed in their system. Waiting too long to respond to these requests can result in additional storage fees being charged by the bonded warehouse.
