Routes
Shipping from Korea: ports, air cargo and routes
Korean freight leaves through a small number of well-equipped gateways. Which one you use, and how the cargo is routed after that, sets most of your transit time and cost.
Seaports
- Busan is Korea's largest container port. Most transpacific and Asia–Europe container services call here, and it is also a major transshipment hub for cargo from China and Japan.
- Incheon serves the Seoul capital area. It is well placed for suppliers around Seoul and Gyeonggi, but has fewer long-haul direct services than Busan.
- Gwangyang on the south coast handles containers and a large share of steel and petrochemical cargo.
- Pyeongtaek-Dangjin and Ulsan are major vehicle and industrial ports.
Cargo from inland factories reaches the port by truck, and in some corridors by rail. Container yard cut-off times at the port, not the vessel's departure time, are what your trucking has to meet. For less than a container load, the deadline is the consolidator's CFS cut-off, which is usually earlier still; see FCL vs LCL.
Choosing a port
- Is there a direct service from that port to your destination, or will the box transship?
- How far is the factory from the port, and what does inland trucking cost against a longer ocean leg?
- Does the carrier's schedule from the nearer port match your production dates?
- For cargo needing special equipment (reefer, open-top, flat rack), which terminals handle it?
Air cargo
Incheon International Airport is Korea's main air cargo gateway and a large hub in its own right. It handles much of the country's export air freight, including semiconductors and electronics. Transpacific freighters often route via Anchorage for a technical stop before reaching US gateways. Korean airlines and many foreign carriers operate freighters from Incheon, and belly capacity on passenger flights adds more.
Express integrators and the postal network also run out of Incheon. They carry most of the small parcels that Korean brands sell online, which now need a US entry whatever their value; see US de minimis after 2025.
Ocean or air?
| Factor | Ocean container | Air cargo |
|---|---|---|
| Transit | Weeks, plus port and inland time | Days, including handling |
| Cost basis | Per container (FCL) or per cubic meter or ton (LCL) | Per chargeable kilogram (the greater of actual and volumetric weight) |
| Suits | Heavy, bulky, lower-value or planned replenishment | High-value, urgent, small or time-sensitive goods |
| US advance filing | ISF from the importer plus carrier manifest | Air advance cargo data via carrier and forwarder |
| Dangerous goods | IMDG Code | IATA Dangerous Goods Regulations, generally stricter for lithium batteries |
Routings to the United States
| Destination | Common routing | What to expect |
|---|---|---|
| US West Coast | Direct services from Busan to Los Angeles/Long Beach, Oakland, Seattle/Tacoma | About two weeks port to port on a direct service |
| US Midwest | West Coast port, then rail (intermodal) | Ocean time plus rail and terminal dwell |
| US East and Gulf Coast | All-water via the Panama Canal, or West Coast plus rail | Roughly a month or more all-water; canal and rail conditions both matter |
Transit times vary by carrier, service and season. Treat these as orientation, not schedules, and use the carrier's published schedule for the sailing you book. For US-bound ocean cargo, the importer's ISF must be on file at least 24 hours before loading in Korea, so the booking and the document timeline have to be planned together.
Routings to Europe
Asia–North Europe and Asia–Mediterranean services normally connect Busan with hubs such as Rotterdam, Antwerp-Bruges, Hamburg and Piraeus via the Suez Canal. Since late 2023, security problems in the Red Sea have led many carriers to route around the Cape of Good Hope at times, which adds a week or more. Check your carrier's current routing before promising a delivery date. Air freight from Incheon to European hubs is the alternative when time matters. On arrival, the EU's ICS2 system needs safety and security data before the goods reach Europe, and preferential duty depends on a valid EU–Korea origin declaration.
What drives transit time
- Port cut-offs and documentation deadlines before departure
- Direct services or transshipment through another hub
- Port and rail congestion at the destination
- Customs holds and inspections, often triggered by incomplete or inconsistent data
- Final-mile drayage and appointment availability at the warehouse
Agree who is responsible, and where
The Incoterms rule in your sales contract (for example FOB Busan, FCA Incheon, or DAP at the buyer's warehouse) decides who books the freight, who bears the risk at each stage, and who files which declarations. Choose it deliberately; Incoterms 2020 for Korea trade compares the options. The rule you agree also decides who needs visibility of the shipment, a subject covered in tracking and custody.
Common questions
How long does shipping from Korea to the US take?
On a direct ocean service from Busan to the US West Coast, roughly two weeks port to port, before origin trucking, terminal time, customs and final delivery. East Coast and inland destinations take longer. Air cargo takes days. Always check the specific carrier schedule.
Should I ship from Busan or Incheon?
Busan has the widest choice of long-haul direct services. Incheon can save inland trucking for suppliers near Seoul, but may involve transshipment. Compare total door-to-door time and cost, not just the ocean leg.
Does the Red Sea situation affect Korea–US shipments?
Transpacific services to the US West Coast do not use the Suez Canal. Europe-bound services and some all-water routings to the US East Coast can be affected, so check the carrier's current routing.
