Trade lane

What Taiwan buys from South Korea.

Taiwan imported USD 36bn of manufactured and processed goods from South Korea in 2024, up 50 per cent on 2022. That is 14 per cent of everything Taiwan imported in these lines, and South Korea is its number 3 source. Below: the 50 largest lines, the fastest growing, where South Korea dominates, and where another country ships the same line for less a tonne.

Trade year 2024, compared with 2022. Unit values are customs values per tonne, declared at the border, not product prices.

The top 50

The largest lines on the lane, by 2024 value.

Each line shows what Taiwan paid South Korea for it at the border, South Korea's share of everything Taiwan imported in that line, how it changed since 2022, and the customs unit value per tonne where the weight is recorded. Together they are 88 per cent of the lane.

What this record says

What crossed the border, what it was worth, and what it weighed.

Every figure on this page is from CEPII's BACI file, which reconciles what each pair of countries reports to the UN about the same shipment. Trade year 2024, compared with 2022. A line is one six-digit customs heading (HS 2022). Values are in US dollars at the border; growth is in current dollars, so part of any change is price, not volume.

Unit value. Unit values are customs values per tonne, declared at the border, not product prices. It is the value of a line divided by its declared weight, so it mixes grades, models and qualities under one heading. It is shown only where the weight is recorded, at least three source countries of USD 100k or more ship the line to Taiwan with a weight, and the figure sits within a factor of five of the middle of those sources. Outside that band it is treated as a recording problem and left out.

Share is South Korea's part of everything Taiwan imported in that line, from every source. Sources counts the countries that shipped any of it.

Scope. Manufactured and processed goods, customs chapters 16 to 96, without ores, fuels, precious metals, scrap, raw farm output and one-off capital and defence purchases: the same rule as the Made here pages.

What it does not say

A record of trade, not a shopping list.

What this record does not say: what sells at retail, what margin a trade leaves, how crowded the marketplaces are, or how much of a flow is re-exported through entrepots such as Hong Kong and Singapore.

A large line is not proof of an opening, and a lower unit value from another country is not proof the goods are the same. Tariffs, standards, freight, payment terms, lead times and the plain fact that a supplier is good at it are all invisible here. Nothing on this page is a forecast, a recommendation or a promise. No supplier company is named, because the record holds none.

Want to know when this lane moves?

A sourcing alert for South Korea to Taiwan is not built yet. If it is built, it would tell you when a line on this lane shifts: a new source country, a share that moves, a unit value that changes sharply. Leave an address and you will hear when it exists, and nothing else.
