Why Plain Milk Is Expensive in South Korea: Raw-Milk Costs, Distribution Margins, and the A2 Premium
An analysis of Korean white-milk prices through farm-gate costs, distribution structure, A2 positioning, and the 2026 removal of FTA tariffs.
Summary
Plain white milk is expensive in South Korea for three main reasons:
- Raw-milk production costs are high because dairy farms depend on imported feed. The cost is about KRW 1,003 per litre, more than twice the U.S. and EU range.
- Retail and distribution margins have risen much faster than the farm-gate milk price.
- Premium strategies such as A2 milk raise the market’s price reference point.
The abolition of further FTA tariffs in 2026 adds pressure. Domestic milk self-sufficiency has fallen to 45.8%.
Falling consumption of Korean white milk
The hesitation people feel when picking up a carton in a Korean supermarket is not imaginary. Total per-capita dairy consumption is still about 80 kg, but plain white-milk consumption fell to 22.9 kg in 2023, the lowest level since the late 1980s. People still eat yogurt and cheese, but the carton of milk is disappearing from the refrigerator.
The largest reason is a shrinking core customer base. South Korea’s total fertility rate was below 0.80, and the number of children entering elementary school fell about 29% from 2020. Children are among the heaviest milk drinkers, so school-meal demand is directly affected. Plant-based alternatives such as oat and almond milk also grew from KRW 646.9 billion in 2022 to a projected KRW 743.0 billion in 2026.
| Indicator | Figure | Note |
|---|---|---|
| Per-capita dairy consumption | about 80 kg | broadly stable |
| Per-capita white-milk consumption (2023) | 22.9 kg | lowest since the late 1980s |
| Total fertility rate (2025) | below 0.80 | core consumer base is shrinking |
| Elementary-school entrants | about 29% lower than 2020 | school-meal demand hit directly |
| Plant-based milk market (2026 forecast) | KRW 743.0 billion | continuing growth from 2022 |
Why Korean raw milk costs so much to produce
The cost of producing one litre of Korean raw milk is about KRW 1,003–1,084, compared with roughly KRW 400–500 in the United States and the EU. That can look like inefficiency, but Korean dairy productivity is not weak: annual yield per cow is about 9,273 litres, among the world’s top tier.
The structural constraint is geography. South Korea lacks extensive pastureland and depends on imported feed. Productivity cannot fully overcome imported-feed costs and high land prices. Dairy work is also relentless: cows must be milked every day. The sector is aging—56.4% of dairy operators were in their sixties or older in 2024, and 38.9% of farms had no successor.
| Country | Raw-milk production cost (KRW/L) | Annual yield per cow | Main cost drivers |
|---|---|---|---|
| South Korea | about 1,003–1,084 | 9,273 | imported feed, high land costs |
| United States / EU | about 400–500 | varies | relatively lower feed and labor costs |
Farm-gate milk prices versus shelf prices
The key issue is not raw milk alone. From 2017 to 2021, the price dairy farmers received rose 1.8%, while consumer prices rose 8.9%—about five times as much. In 2022, farm-gate prices rose only 2.5%, while consumer prices increased by 4.7% to 9.6%.
| Period | Farm-gate price increase | Consumer-price increase | Gap |
|---|---|---|---|
| 2017–2021 | 1.8% | 8.9% | about 5.0× |
| 2022 | 2.5% | 4.7%–9.6% | about 1.9–3.8× |
More than 30 small dairy processors negotiate with concentrated retail channels—hypermarkets, convenience stores, and SSMs (super-supermarkets, a Korean small-format supermarket channel). The processors are in the weaker position and face high shelf margins. Even when raw-milk prices are restrained, the saving does not necessarily reach consumers.
South Korea’s raw-milk price-linkage system, introduced in 2013, also matters. It mechanically links purchase prices to changes in production costs and consumer inflation. When demand falls, prices do not easily fall with it.
Are dairy companies making windfall profits?
Not necessarily. Food-industry operating margins average around 6–7%, while major Korean dairy companies are below that level.
| Dairy company | Operating margin | Note |
|---|---|---|
| Seoul Milk | about 2% | roughly KRW 2 trillion revenue; about KRW 40 billion operating profit |
| Maeil Dairies | about 4% | includes diversification such as nutrition products |
| Namyang Dairy | about 0.5% (2025) | returned barely to profit after years of losses |
| Yonsei Milk | about 4–5% | effects of efficiency measures and exports |
Producers struggle, processors struggle, and consumers pay high prices. The distribution stage captures a disproportionate share.
Why Korean white milk is almost impossible to export
It is tempting to think that, because Korean food exports are growing, Korean milk could be exported too. Fresh white milk is commercially close to impossible to export.
Fresh pasteurized milk has a shelf life of only 10–14 days. Sea freight and customs clearance make spoilage likely; air freight is possible but the logistics cost of a heavy liquid destroys competitiveness. The product also needs a strict 0–10°C cold chain, while inland cold-chain infrastructure in many potential Southeast Asian markets remains limited.
UHT milk solves the shelf-life problem, but not the price problem.
| Exporting country | Milk export unit price (USD/kg) | Note |
|---|---|---|
| Uruguay | 1.29 | pasture-based, low-cost production |
| Costa Rica | 1.40 | emerging dairy exporter |
| Argentina | 1.75 | major South American dairy producer |
| Poland | 3.08 | competitive within the EU |
| South Korea | not commercially viable | production cost alone exceeds about USD 0.70–0.80, before freight |
Australia and New Zealand already dominate the Asia-Pacific export market. Korean white milk is therefore structurally dependent on domestic demand.
What is A2 milk?
With weak domestic consumption, difficult exports, and import pressure, Korean dairy companies have turned to premium products such as A2 and Jersey milk.
Ordinary cow’s milk contains a mixture of A1 and A2 beta-casein. A2 milk comes from specially selected cows that produce milk containing only A2 beta-casein. Its marketing argument is that A1 protein may produce BCM-7 during digestion and contribute to discomfort for some people, while A2-only milk is easier to tolerate.
Seoul Milk invested KRW 8 billion over four years to launch A2+ Milk and announced a plan to convert all of its raw milk to A2 by 2030.
| Category | Example | Size and price | Price per 100 ml |
|---|---|---|---|
| Low-price imported UHT milk | Polish UHT milk at CU convenience stores | — | about KRW 200 |
| Standard domestic white milk | Seoul Milk “Na 100%” | 1,000 ml / KRW 2,960 | about KRW 296 |
| Premium A2 milk | Seoul Milk “A2+” | 710 ml / KRW 3,580 | about KRW 504 |
The premium product costs about 70% more than standard milk. At the other end of the market, directly imported Polish UHT milk is more than 35% cheaper than standard domestic milk.
A hollowing-out of ordinary domestic milk
Consumers focused on value move to imported UHT milk; consumers willing to pay for health move to premium milk. Standard domestic white milk is squeezed between them in an hourglass-shaped market. UHT milk imports rose from 23,000 tonnes in 2021 to 48,000 tonnes in 2024, more than doubling.
Three controversies around A2-milk marketing
1. Raising the price anchor
If the market leader converts all of its lines to premium products, competitors may follow with price increases. Consumers who were satisfied with standard milk can end up paying more. The industry argues that prices will stabilize once scale economies arrive, but that is difficult to square with chronic cost pressure and the current distribution-margin structure.
2. The self-defeating logic of fear marketing
To say “A2 is better” can imply that ordinary A1-containing milk is problematic. That risks casting doubt on products the same companies have promoted for decades as complete, wholesome foods.
3. Incomplete scientific evidence
Nutrition experts have noted that many clinical studies cited for A2-milk benefits were funded by interested companies, including Australia’s a2 Milk Company. Much of the BCM-7 research also relies on animal models; scientific evidence in humans remains insufficient. A premium claim should be presented with that uncertainty, not as a settled health fact.
