South Korea is a powerful economic force, ranking as the world’s 13th largest economy and a global leader in high-tech industries. The United States remains one of its most significant trading partners, making shipping from Korea to the U.S. a core operation for importers.
The shipping lanes between the Republic of Korea and the United States account for some astounding numbers: imports of goods were recently valued at US$135.46 billion, while the vessel cargo tonnage is expected to increase by 67%–90% until 2050.
If you’re just getting started, this short guide highlights the essentials of the Korea–US logistics landscape so you can manage your supply chain with confidence.
Get The Facts:
- Fastest Sea Route: Port of Busan to Los Angeles/Long Beach
- Average Transit Times for this route: FCL 18 days, LCL 22 days (port-to-port)
- Ocean Shipping Costs: FCL 40’ $3,124 (average); LCL $45–$65 per CBM

Ocean Freight From South Korea To The United States (FCL & LCL)
Ocean freight is the most economical solution for moving high volumes of cargo between container ports of South Korea and U.S. ports. Shipping times take approximately 2 weeks to a month, depending on the type of load (LCL or FCL) and service level.
Top Shipping Routes From South Korea To The U.S.
There are three critical and high-volume routes that connect Korean manufacturing hubs to major US consumer markets:
Busan to Los Angeles/Long Beach, CA
This foundational route is popular for high-volume electronics and consumer goods due to direct service and competitive rates.
Busan to New York/New Jersey, NY
A crucial trade lane for East Coast distribution and automotive parts.
Incheon to Los Angeles, CA
This route supports Seoul-area manufacturers and time-sensitive cargo with frequent departures.
Air Freight From South Korea To The United States
Air freight from South Korea to USA shortens transit times from weeks to days: roughly 3 days airport-to-airport and 5–10 days door-to-door for standard shipments.
Express Air Freight From South Korea To The U.S.
For the fastest door-to-door service, and small shipments under one cubic meter and 200 kg, express services are the quickest, offering delivery times of just 2–5 business days door-to-door. This service, though, is mostly used for small parcels and courier services.
How Long Does It Take To Ship From Korea To The US?
Freight transit times between Korea and the U.S. vary, depending on the level of service, load type, and, for ocean freight, the distance between the port pairs.
Average Transit Times From Korea To West Coast, U.S.
| Shipping Method | Transit Time (Korea – West Coast U.S.) |
| Express Courier door-to-door | 2–5 business days |
| Air Freight airport-to-airport | 3–8 days |
| Ocean Freight (FCL) port-to-port | 15–21 days |
| Ocean Freight (LCL) port-to-port | 18–25 days |
Longer transit times apply to East Coast destinations. For instance, shipping from Busan to New York, NY via FCL (port-to-port) takes 25-32 days, and LCL takes 28–35 days.
Note that LCL shipments generally take a few days longer than FCL due to the mandatory consolidation/deconsolidation process.
How Much Does It Cost To Ship From Korea To America? (Ocean & Air Freight)
When shipping from Korea to USA, prices are impacted by mode, weight, dimension, fuel prices, capacity, season, and route.
Ocean Shipping Costs (FCL & LCL): Port Of Busan To Port Of Los Angeles/Long Beach
Ocean freight is the cheapest way, especially if using FCL outside of peak season.
- LCL: $45-$65 per CBM
- FCL 20′: $2,100-$3,200
- FCL 40′: $3,124 (average)
When shipping to the East Coast, prices differ. Here’s an example:
A 20’ FCL container from Incheon to Los Angeles, CA starts at $4,143, while the same-sized container from Busan to New York, NY is considerably higher, starting at $5,678.
Air Cargo Costs Korea-U.S.
Air freight costs are tiered, decreasing per kilogram as weight rises. For medium-to-large shipments, the typical air freight range is $7–$12/kg.
In more detail:
- 100 kg shipment: the price is approximately $12.72/kg.
- 300 kg or more: rates drop to about $7.21/kg.
- Express Courier service: $12–$18/kg. For example, a small 10 kg express shipment can cost around $223.
KORUS FTA: Why Most Korean Imports Are Duty-Free
If you’re sourcing from South Korea, the trade agreement between the two countries is the single biggest lever on your landed cost, and it’s worth knowing even if your freight forwarder handles the paperwork.
Under the KORUS Free Trade Agreement, more than 95% of Korean industrial and consumer goods enter the US duty-free. Electronics, automotive parts, and most consumer goods qualify for zero-tariff treatment when they meet the agreement’s origin rules. Qualifying shipments also skip the Merchandise Processing Fee, which saves 0.3464% of your cargo’s value on every shipment, a small percentage that adds up on higher-volume imports.
None of this is automatic. You need a Certificate of Origin showing your goods meet KORUS’s origin requirements, and your supplier needs to confirm the goods qualify before you rely on the duty-free rate in your cost planning.
Best US Ports for Korea Shipments (By Coast)
Busan to Los Angeles/Long Beach is the fastest and most common route, and it’s the right default for most first-time importers from Korea. But it’s not your only option, and the right port depends on where your business actually is.
If your warehouse or customers sit on the East Coast, routing through New York/New Jersey often beats trucking cargo cross-country from LA, especially for electronics and automotive components, two categories with strong direct Korea-to-NY/NJ service. Seattle/Tacoma works as a secondary West Coast gateway with solid rail connections inland, useful if Los Angeles congestion is running high. Savannah and Charleston are newer but growing options for businesses distributing across the Southeast.
Your freight forwarder should be routing you based on your actual delivery destination, not defaulting to the busiest port by habit.
