The short answer

  • China leads Korea’s 2025 export and import rankings; the United States follows. The EU is a regional bloc, so including it changes the numbering of individual economies.
  • Chips account for 40.5% of January–August 2026 exports, calculated from the Customs Service’s published amounts.
  • Korea’s China balance was already +$27.678 billion in January–August 2026. An eight-month surplus is not a full-year result.

At Busan New Port, containers carry Korean goods abroad and bring in the inputs used to make the next shipment. A shopping bag leaving a Myeongdong store represents another kind of cross-border demand. The two scenes belong to the same economy, but they do not always enter the same statistical account.

The useful map separates three questions: who buys Korean goods, who supplies Korea, and how much of the trade is concentrated in chips. It also keeps a completed year separate from a partial year. The figures below were checked on November 1, 2026; the 2026 comparison deliberately covers January–August.

How much does Korea sell and buy?

In the Customs Service’s January 26 summary, 2025 exports were $709.4 billion and imports $631.8 billion. The reported surplus was $77.7 billion, the largest since 2017. Korea passed $700 billion in annual exports for the first time. January–August 2026 exports had already reached $693.588 billion, but comparing eight months with twelve does not establish a full-year result.

PeriodExports ($B)Imports ($B)Balance ($B)
2025 full year709.4631.8+77.7
Jan–Aug 2026693.588490.964+202.624
August 202698.28263.497+34.785

2025: rounded figures from the January 26, 2026 summary, which said annual figures could be revised through February. 2026: the September 15 monthly release, labeled “final” for August, also says annual revisions remain possible through February 2027. Different release dates and product classifications can change the amounts; they are not interchangeable datasets.

Who are Korea’s major trading partners?

China is first in both exports and imports in the 2025 Customs Service summary. The selected two-way comparisons below use that single publication. Totals and balances are calculations from its amounts rounded to $0.1 billion; this is not an official ranking by trade balance.

Selected partnerExports ($B)Imports ($B)Total ($B)Balance ($B)
China130.8141.9272.7-11.1
United States122.973.4196.3+49.5
EU70.166.7136.8+3.4
Taiwan49.132.381.4+16.8

That publication’s top five export markets are China ($130.8B), the U.S. ($122.9B), the EU ($70.1B), Vietnam ($62.8B) and Taiwan ($49.1B). Taiwan is directly reported by Korean customs; no estimate from export shares is needed. The EU is treated as one market in this list, so Taiwan is fifth with the EU included and fourth among individual economies. A claim that Taiwan simply disappears from all international statistics is too broad.

What does Korea sell and import?

Semiconductors lead both sides of Korea’s goods trade. The 2025 summary reports $175.3 billion of chip exports, or 24.7% of all exports. Passenger cars follow at $68.5 billion. Chips, passenger cars, steel products, petroleum products and ships together account for 51.7%. The table uses the Customs Service’s product classification throughout.

2025 export itemAmount ($B)Annual change
Semiconductors175.3+21.9%
Passenger cars68.5+0.3%
Steel products46.0-4.5%
Petroleum products46.0-9.4%
Ships30.4+24.0%

For January–August 2026, chip exports were $281.184 billion, up 169.6%. Dividing by the same release’s $693.588 billion total gives 40.5% to one decimal place. This is a share of export value, not cargo weight or the number of containers. Growth in a product’s dollar value can reflect both volume and price; it does not by itself prove either one doubled.

2025 import itemAmount ($B)Annual change
Semiconductors77.5+4.9%
Crude oil75.3-11.8%
Gas30.5-12.1%
Machinery30.3+7.8%
Semiconductor manufacturing equipment26.7+18.6%

Chips were 12.3% of 2025 imports and crude oil 11.9%. The Customs Service puts crude oil, gas and coal together at about 19% of import value; gas is the category reported here, not a table limited to LNG. Korea’s chip imports serve a different mix of uses from its chip exports, so a large exporter can also be a large importer.

Saudi Arabia was the largest crude-oil supplier by value in that publication, at $25.7 billion, followed by the U.S. ($12.9B), UAE ($8.8B), Iraq ($7.7B) and Kuwait ($6.3B). Those are crude-oil amounts, not each country’s total exports to Korea. Separately, the Korea Energy Economics Institute’s December 2025 data put energy import dependence at 92.9% (provisional): the imported share of primary energy supply. It is a different measure from energy’s share of merchandise imports.

Where do U.S. semiconductor tariffs fit?

“Chips escaped tariffs” is too sweeping. The U.S. proclamation of January 14, 2026 imposed a 25% Section 232 duty on a narrowly defined category of advanced computing chips and certain derivative products, with specified end-use exemptions, including U.S. data centers and research. It also contemplated broader measures after negotiations. That dated action does not establish one current rate for all Korean chips. The 2025 Customs Service summary records passenger-car export growth of 0.3% and semiconductor growth of 21.9%; those outcomes alone do not isolate the causal effect of tariffs.

Has the China balance changed?

Yes: the January–August 2026 China balance was a surplus. The Customs Service reported exports to China of $145.383 billion and imports of $117.705 billion, producing a $27.678 billion surplus. The 2025 summary’s rounded amounts imply an approximately $11.1 billion deficit. The partial-year reversal is established; a 2026 annual balance cannot be declared before the year ends.

Jan–Aug 2026 partnerExports ($B)Imports ($B)Balance ($B)
China145.383117.705+27.678
United States127.49660.067+67.429
EU55.52049.931+5.589
Taiwan47.52327.933+19.590
Vietnam63.13325.164+37.969
Japan21.42336.440-15.017
Hong Kong53.8382.144+51.694

These are reported balances from the same September 15 release, not ranks inferred from an incomplete list. Vietnam’s figures describe a trading relationship; they do not show that every shipment goes to a Korean-owned factory. Likewise, Hong Kong’s totals do not by themselves measure how much trade is re-exported to mainland China.

What does trade dependence actually measure?

A trade-to-GDP ratio depends on what is counted. Customs goods exports and imports differ from the national-accounts measure of goods and services. Combining a dollar GDP projection with a differently dated trade total produces an inconsistent ratio. The Bank of Korea’s March 10, 2026 provisional release gives 2025 nominal GDP of ₩2,663.3 trillion and GNI per person of $36,855; GNI per person is not GDP per person. The Customs Service’s statement that Korea became the sixth economy to pass $700 billion in annual exports is a milestone, not a current world-export ranking.

How far does Korea’s FTA network reach?

Count agreements separately from partner countries. The Chungnam FTA center lists 23 agreements in force covering 60 countries, rather than “23 countries and regions.” The ministry’s RCEP chronology confirms that RCEP entered into force for Korea on February 1, 2022. A digital agreement such as DEPA should not be inserted into a goods-FTA list as though the categories were identical. The official FTA portal provides the status of individual negotiations.

How do trade partners overlap with visitors?

The main visitor markets overlap with major trade markets, but the lists measure different things. Korea Tourism Organization’s January 30 release reports 18,936,562 inbound visitors in 2025. Its leading five markets are below. Use the same year when comparing visitor markets; a country’s export rank, import rank and visitor rank need not match.

2025 visitor marketVisitors
China5,480,969
Japan3,653,137
Taiwan1,891,414
United States1,483,240
Hong Kong623,149

These are visitor arrivals, not unique people or merchandise transactions. China, Japan, Taiwan, the U.S. and Hong Kong have strong travel links with Korea, but the table does not prove that trade caused the visits. Nor does a trade deficit against Japan mean Korea “wins on people”: tourist counts and trade balances cannot be subtracted from one another.

How should travelers read duty-free shopping?

The purpose of the purchase matters more than the duty-free label. UN Comtrade’s explanation of IMF balance-of-payments rules distinguishes travelers’ personal purchases from goods bought for resale. Personal-use goods and gifts generally belong in travel services; goods acquired for resale belong in merchandise. Personal purchases above customs thresholds that enter customs statistics can also fall under merchandise. A container is not the deciding test.

That distinction matters for daigong, travelers who purchase goods for resale. Their purchases cannot all be called ordinary tourist spending. For an ordinary visitor, the practical question remains simple: compare local and home prices, check baggage limits, and buy what you will use.

What do the K-beauty and K-food records mean?

The records refer to different product scopes. The industry ministry’s January 1 release reported record 2025 cosmetics exports of about $11.4 billion and agri-fishery food exports of about $12.4 billion. MAFRA’s January 12 release separately reported $10.41 billion of agri-food exports, including about $1.52 billion of ramyeon; its broader K-Food+ total of $13.62 billion also includes agricultural industries. These categories should not be substituted for one another or added to tourist shopping as though they were separate pieces of a single total.

Korea’s trade map combines a large chip cycle, two-way industrial supply chains and energy imports. A useful reading starts with the period, the reporting agency and the definition. The verified January–August 2026 snapshot shows both strong chip concentration and a China surplus; it does not certify a full-year forecast or tell us what is inside every departing ship.
