The United States and South Korea have a free trade agreement that they entered into in 2012. Because of that, trade relations between the two countries continue to strengthen year after year. In 2022, the U.S. exported $72.1 billion worth of goods to Korea, a 9.5% increase from the previous year ($6.3 billion). 


If you need to ship goods from the United States to South Korea and are looking to take advantage of the two countries' trade relations, you’ve come to the right place. Here’s your complete guide to your ocean and air freight shipping options, the customs clearance process, and more. 


What Are the Options for Shipping Freight From the United States to South Korea?


To ship freight from the United States to South Korea, you can choose ocean freight or air freight, depending on your needs and the requirements of your cargo. 


Ocean Freight From the United States to South Korea


Ocean freight is the most cost-effective shipping option. Depending on the type of container shipping you select, it doesn’t cost too much to get your goods to their destination. Ocean freight is also quite flexible. It can ship a range of goods and offers shippers two options: less than container load or full container load


LCL is ideal for those shipping small goods or shipping in small volumes. Here, your goods will be consolidated with cargo belonging to other sellers and shipped together in one container. That way, they only pay for the space their cargo occupies. 


On the other hand, a FCL is when the shipper rents the space in an entire container for their goods alone. This method allows them more control over their shipment. It’s also more secure because of its lack of a consolidation process. 


Air Freight from the United States to South Korea


Another option for shipping freight from the United States to South Korea is air freight. It’s the fastest shipping option, taking only days for your cargo to arrive at its destination. Thanks to stricter airport regulations, air freight is also a secure way to ship high-value goods. 


The main disadvantage of air freight is its cost. It’s the most expensive mode of shipping. It also has limitations regarding what you can and cannot ship by air. 


How Much Does it Cost to Ship Cargo From the United States to South Korea?


The cost of shipping cargo from the United States to South Korea will depend on a couple of factors, including: 


  • Your choice of ocean or air shipping
  • Your preference for door-to-door, port-to-port, port-to-door, or door-to-port shipment
  • Your consignment’s weight, volume, and size
  • Weight and size limits

For the most accurate estimate, we recommend using our transit time calculator.

Customs Clearance in the United States and South Korea


Once your goods finally reach Korea, the next step is the customs clearance process. This can be quite a breeze as long as you make sure the following documents accompany your shipment: 


  • A commercial invoice
  • A packing list
  • A certificate of origin
  • A letter of credit or other payment terms (depending on the contract between the parties involved)
  • A bill of lading for ocean freight or an Airway Bill for air freight

See our full documents list for examples of each customs clearance requirement. 


Should You Choose Ocean Freight or Air Freight?


The choice between ocean freight or air freight for your United States to Korea shipment will depend on your needs as a shipper and the requirements of your cargo. Here are some things to consider to help you make the right decision. 


Ocean Freight


Ocean freight is best if you’re a budget-conscious shipper who doesn’t want to spend too much on shipping from the United States to South Korea. Because it’s flexible, it can also work well for shippers with unique cargo or shipping needs. 


If you choose ocean freight, you must select between less than container load or full container load. 


Considerations for LCL Freight Shipping


LCL is the best option for you if your cargo is: 


  • Small in size and quantity 
  • Lightweight
  • Suitable for consolidation with cargo belonging to other shippers
  • Not delicate, fragile, or high-value 
  • Not requiring special handling or movement 

Considerations for FCL Freight Shipping


On the other hand, you might be better off with FCL if your cargo is: 


  • Large in size and quantity 
  • Heavy or overweight
  • Not suitable for consolidation with cargo belonging to other shippers 
  • Delicate, fragile, or high-value 
  • Requiring special handling or movement 

Air Freight


If your priority is getting your goods to South Korea fast, air freight is the shipping mode for you. It only takes a couple of days to complete, and it’s best for high-value, time-sensitive, and perishable goods. Thanks to its more stringent regulations, air freight can also keep your cargo safe. However, this also means there are restrictions as to what you can and cannot ship by air. 


It’s also worth noting that air freight is the most expensive shipping option, so make sure to check your budget before opting for air freight.
