It’s been a sobering week for the cement sector in South Korea with the release of sales data for the first half of 2025.

Data from the Korea Cement Association (KCA) shows that local shipments of cement fell by 17% year-on-year to 18.8Mt in the first half of the year. The last time half-year output was reported to be below 20Mt was in 1992. The association noted that a ‘severe’ construction recession had continued from 2024. An uptick in demand for building materials is anticipated in the second half of 2025 due to postponed construction work but it is expected to be limited by a forthcoming government budget. The association said that output for the whole of 2025 is forecast to be “significantly below 40Mt unless effective construction stimulus measures are available.”

20Mt of cement output marks a dividing line in the South Korea-based market in recent decades. Previous economic low points over the last 30 years include the Asian Financial Crisis in the late 1990s and the 2008 financial crash triggered by the subprime market in the US. However, on neither occasion did half-year cement output in South Korea fall below 20Mt. The current situation is likely to be reflected in the financial results of the local manufacturers, when they are released later in August 2025, following poor first-quarter figures.

The general construction sector is facing a tough time, with construction companies facing a liquidity crunch as lending rules have been tightened. At the same time prices and labour costs are both reportedly up by 30% in the past three years. One reaction to this in Autumn 2024 was plans suggested by construction companies to import cement from China. This gained some support from the government, which said it was looking at ways to reduce costs, but then faced opposition in the National Assembly. It is unclear what has happened since then, although KCA figures show that imports of cement grew by 40% year-on-year to 384,000t in the second half of 2024.

The cement producers have reacted by shutting down production lines in some cases. In April 2025 local press reported that eight of the country’s 35 production lines had been shut down. Hanil Cement’s Danyang plant had reportedly suspended two of its six production lines. One additional kiln at Asia Cement’s Jecheon plant was preparing to be closed at this time, with the manager citing the difficulty of coping with a 70% capacity utilisation rate. This would have brought the site’s number of active lines down to two of four. Another unmentioned kiln also reportedly preparing to suspend operations would bring the total of inactive kilns up to 10.

As might be expected in this kind of business environment, mergers and acquisitions activity has started. Hanil Cement announced in mid-July 2025 that it was preparing to buy its subsidiary Hanil Hyundai Cement. The transaction is expected to cut costs of the newly combined company and yield other synergy effects.

With its high cement consumption per capita, the cement market in South Korea remains atypical compared to peer economies in East Asia and Europe. Consumption dropped after a peak in the 1990s but it remained high by international standards. Hence the outcry about a half-year cement output bigger than most European countries can manage in a year. The IMF predicts a gross domestic product (GDP) growth rate of 0.8% in 2025 in South Korea, with a faster pickup of 1.8% in 2026. Construction levels are expected to remain sluggish into autumn and start recovering in 2026. General market trends in developed countries suggest that cement consumption will fall further in South Korea in coming decades, especially as sustainability trends embed. Cement sales in Japan, for example, have gradually been dwindling since the late 1990s. One question here is whether the cement market in South Korea can continue to hold its high level of consumption per capita. It remains to be seen.

South Korea: Domestic cement consumption fell by 22% year-on-year to 8.12Mt in the first quarter of 2025, the lowest figure for first-quarter sales in five years, according to Chosun Biz news. This marks a 32% (3.9Mt) drop from the 2023 peak of 12Mt. A domestic decline of more than 20% in the first quarter has not been seen since the 1998 financial crisis. At that time, first-quarter domestic sales decreased by 23% to 8.9Mt.

Cement companies have seen a corresponding decline in revenue. Hanil Cement’s operating profit dropped by 75% year-on-year to US$9m, Asia Cement’s fell by 70% year-on-year to US$2.4m and SAMPYO Cement’s declined by 90% to US$1.15m. Ssangyong C&E and Sungshin Cement both reported operating losses of US$19m and US$4.4m respectively.

A Cement Association representative said "For the time being, the decrease in domestic cement consumption is likely to continue, and management performance will further deteriorate. Unless a groundbreaking measure to overcome the construction market slump emerges, the forecast of 40Mt of domestic cement consumption in 2025 seems doubtful."

South Korea: Jeon Geun-Sik, the CEO of Hanil Cement and Hanil Hyundai Cement, has been appointed as the president of the Korea Cement Association.

Geun-Sik started working for Hanil Cement in 1991, according to Chosun Daily. During his time with the company he has worked as the deputy head of the Danyang plant, head of corporate management planning, management head, senior vice president of Hanil Hyundai Cement headquarters and the CEO of Hanil Holdings. He has been the CEO of Hanil Cement and Hanil Hyundai Cement since 2022. Geun-Sik is a graduate of the Hanyang University in Seoul.

South Korea: Hanil Cement has appointed its chief executive officer (CEO) and vice-president Jeon Gun-Sik as its president. He first joined the company in 1991, according to the Maeil Business Newspaper. He worked as the vice plant manager of the Danyang Plant, the head of the business planning department, the head of the business division and the executive vice-president of the head office of Hanil Hyundai Cement. Notably in 2017 he oversaw the acquisition of Hyundai Cement, a subsidiary now known as Hanil Hyundai Cement, that he also runs as CEO and president.

There has been a significant investment in the South Korean cement industry this week with the news that Hanil Hyundai Cement has ordered a steam-based waste heat recovery (WHR) system from Japan-based Kawasaki Heavy Industries. The 22.6MW system will be used on two of the production lines at the Yeongwol plant in Gangwon Province. The supplier says that installation is expected to generate about 30% of the energy the plant needs and save around 10,000t/yr of CO₂ in the process. Delivery is scheduled for late 2022.

This order may be the first investment following the announcement in late June 2021 that the state-owned Korea Development Bank had pledged around US$870m towards supporting the cement sector in making carbon reduction upgrades by 2025. These are intended to include moving away from burning fossil fuels in cement production and increasing the use of recycling materials. At the time of the agreement between the bank and the Korea Cement Association (KCA), Hanil Hyundai Cement noted that the local alternative fuels substitution rate was 24% compared to 46% in the European Union and 68% in Germany.

By European or American standards South Korea kept its coronavirus cases under control in 2020. A robust testing and contract tracing regime (K-Quarantine) managed to prevent the country enforcing stricter measures until late in 2020. A fourth wave of infections, currently underway in July 2021, due to the more contagious Delta variant, has started to change this. Despite being able to keep its economy open though, the construction sector still took a hit although not as bad as initially feared.

Cement production fell by 6% year-on-year to 47.5Mt in 2020 from 50.6Mt in 2019 following a downward trend since 2017. The KCA expected worse after a poor third quarter in 2020 when it was preparing for shipments to fall below the level last seen in the midst of the International Monetary Fund (IMF) crisis in the late 1990s. On top of this the industry was also potentially facing a new tax on production towards the end of 2020. One large local producer, Ssangyong C&E, reported a 5% year-on-year drop in sales to US$864m in 2020 from US$910m in 2019. However, it managed to increase its operating profit over the same period. So far in 2021 the sector faced supply shortages in the spring. The KSA blamed the winter plant maintenance schedule and a lack of railway wagons and trucks.

The timing of the Korea Development Bank investment in the cement sector is interesting given the movement on the European Union carbon border adjustment mechanism. Cement exports seem unlikely to be affected but business lobbyists like the Federation of Korean Industries are well aware of the effects schemes like this might have upon commodities like steel and aluminium in the first phase and then the implications for car production later on. Target markets for cement exports such as the US, Peru, Chile and the Philippines might all become vulnerable should carbon-based trade restrictions become more prevalent. Of course export markets remain vulnerable to more usual hindrances. For example, in March 2021 the Philippines extended its safeguard measures on cement imports to various countries including South Korea.

Following a round of market consolidation in the late 2010s, the South Korean cement sector now appears to be entering a phase of sustainable realignment. In late May 2021 Prime Minister Moon Jae-in announced plans to hasten the country’s carbon reduction targets ahead of the United Nations Climate Change Conference scheduled for November 2021, including a carbon tax. With cement production on a downward trend since 2017 and the coronavirus crisis far from gone it will be instructive to see how far the intervention of the Korea Development Bank will go.

South Korea: Hanil Hyundai Cement has placed an order with Japan-based Kawasaki Heavy Industries for the design and installation of a 22.6MW waste heat recovery (WHR) unit at its Yeongwol cement plant in Gangwon. The WHR plant will generate power from heat from two of the plant’s production lines when commissioned in December 2022. The supplier says that it will serve 30% of the plant’s energy needs. Kawasaki Heavy Industries says it has previously supplied WHR units to Japan, Germany, South Korea, Turkey, China, Vietnam, India, Pakistan and elsewhere.

South Korea: All nine domestic cement producers and the Ministry of Environment have agreed on measures to reduce NO_x emissions. Asia Cement, Halla Cement, Hanil Cement Manufacturing, Hyundai Cement, Korea Cement, Sampyo Cement, Ssangyong Cement Industrial, SungShin Cement and Union Corporation have agreed to invest in upgrades to filters or new high-efficiency filters and process improvements, according to the Korea Times newspaper. There was also an agreement to set NO_x emissions reduction targets for the allocation of funding. The Korea Environmental Industry Technology Institute is investing US$2.93m in research towards developing methods of selective catalytic NO_x emissions reduction and selective non-catalytic NO_x emissions reduction.

The government aims to reduce national NO_x emissions by 20% to 155,000t/yr from 195,000t/yr through subsidies to emissions reduction technologies development and uptake. The cement sector presently emits 62,500t, 32% of the domestic total.

Asia Cement has completed its purchase of Halla Cement this week for US$723m. The deal has created the third largest cement producer in South Korea with a cement production capacity. This includes one integrated plant at Okgye, three slag grinding plants and a distribution network.

The Halla Cement transaction marks an on-going consolidation process in the local industry. 2017 proved a busy year with the purchase of Daehan Cement by Ssang Yong Cement and Hyundai Cement by Hanil Cement. Assuming the dust has settled this now leaves Ssang Yong Cement and its new subsidiary in the lead by cement production data from 2016 with 12.9Mt or a 23% market share, Hanil Cement next with 12.4Mt or a 22% share and Asia Cement with 10.8Mt or a 19% share. Overall the country produced 56.7Mt of cement in 2016, according to Korea Cement Association data. The remainder of production is shared between six producers.

Fears that the construction industry may have been about to slow down might have prompted Glenwood Private Equity and Baring Private Equity Asia to sell Halla Cement a little earlier than expected. However, they don’t appear to have done too badly out of this. The two private equity firms that bought Halla Cement from LafargeHolcim in 2016 seem to have made a cool US$180m on the deal. At the time it was reported in the local press that they paid US$542m for the cement producer. Glenwood Private Equity was the lead investor followed by Baring Private Equity Asia. They bought Lafarge Halla Cement in May 2016 and then were looking for buyers a year later in August 2017.

Cement consumption in South Korea has followed a rollercoaster path since 1992 hitting a high of 61.7Mt in 1997 and a low of 43.7Mt in 2014. It then rose to 55.8Mt in 2016. The consolidation behaviour by the cement producers suggests either a poor performing market or an uncertain one. Since the gap between the peak and the trough is more than Halla Cement’s production capacity no wonder its private equity owners were keen to get shot of it at the first sign of trouble. So let’s end with the words of Han Chul Kim, Managing Director of Baring Asia, from the time of the purchase from LafargeHolcim in 2016: "We couldn’t imagine a more solid platform from which to access the growth opportunities in the Korean market in the coming years.”

Further shifts in the South Korean cement industry this week as Ssangyong Cement purchased Daehan Cement. Private equity firm Hahn & Company owns both producers so this looked like a realignment exercise. Yet it follows a corporate version of pass-the-parcel within the local cement industry. Hyundai Cement was acquired by Hanil Cement in the first half of 2017, Halla Cement was bought by investment firms from LafargeHolcim in mid-2016 and Tongyang Cement was bought by Sampyo Group in 2015.

Ssangyong Cement’s purchase is seen in the local media as an attempt to reaffirm its market dominance. Before the Hyundai Cement auction, Ssangyong Cement was the market leader with a cement production capacity of 15Mt/yr and a market share of around 20%. Hanil Cement’s on-going purchase of Hyundai Cement will see it increase its production capacity from 7Mt/yr to over 15Mt/yr. Ssangyong Cement’s transaction for Daehan Cement puts it back in the lead again.

The local industry is notable for the high ratio of cement grinding plants to integrated plants. The Korean Cement Association (KCA) reported that the country had 12 integrated plants to 23 grinding plants in 2015. This compares to other developed countries in relatively remote places such as Australia and Chile that also have high numbers of grinding plants. South Korea doesn’t import that much clinker though. One difference is its prominent steel industry that has hovered around 70Mt/yr since 2014 and which puts it in the top ten of world producers. Subsequently, as POSCO’s Sunghee Han explained at the Global Slag Conference 2016, 13.9Mt of granulated blast furnace slag (GBFS) was produced in 2015 and the majority of this ended up being used as supplementary cementitious materials (SCM) either to grind cement or to make concrete. The size of this slag market underlines the value of the Daehan Cement sale, as it is a major slag cement producer.

Other notable point about the local cement industry includes the presence of a few extremely large multi-kiln plants with production capacities in excess of 7Mt/yr. The country also has a relative scarcity of limestone. South Korea is the fifth biggest importer of limestone in the world at US$34m. It brings limestone in principally from the UAE, Japan, India, Malaysia, and Vietnam. Notably it also has one of the world’s longest single conveyors, with a length of 12.8km, connecting a quarry to Ssangyong Cement’s Donghae plant.

Unlike the European cement-producing nations that this column has covered in recent weeks, fundamental market structural changes do not appear to be driving the merger and acquisition activity in South Korea. As Graph 1 shows, production and consumption fell from 2010 onwards but has started to pick up since 2013. Instead, a general slowing of the economy from 2010 and a relaxation of the rules triggered merger and acquisition activity. Unsurprisingly then, perhaps, given the potential opportunities for market manipulation, that the Fair Trade Commission fined six of the seven major producers a total of US$168m in early 2016 for alleged price fixing. With the private equity firms widely expected to exit the market after a relative short time, the cement industry looks set to remain volatile for the next few years. Doubtless the market regulators will be watching very carefully indeed to see how it all plays out.

The 'revelation' this week that South Korean cement producers have been paid US$127m to use/dispose of Japanese coal that is thought to be radioactive certainly sounds scary. If it is true that cement made with contaminated coal has led to the construction of radioactive buildings and roads, this may have prised open a 'can of worms' for coal producers, exporters and cement players alike. According to local media, four South Korean firms - Ssangyong Cement, Tongyang Cement, Lafarge Halla Cement and Hanil Cement - received the money to use the coal between March 2011, when the Fukashima nuclear power plant started to leak radiation, until 2013. A total of 3.7Mt of cement is 'under suspicion.'

Caesium-137 is formed by fission reactions that start with uranium-235 in nuclear reactors. The Fukushima reactor that started leaking in 2011 used this type of fuel. Once it leaked, caesium-137 was deposited into the sea and onto the land, presumably also making its way into nearby coal deposits.

As it is a metal with a melting point of just 28.5°C and a boiling point of 671°C, the caesium-137 would vaporise if it were to enter a cement production line operating at 1450°C as a metal. However, caesium will not enter the cement-making process as a metal due to its rapid and explosive reaction with water. An interesting slow-motion of this reaction can be seen here.

Instead, caesium will enter the cement-making process either as its oxide or a simple salt (e.g.: caesium chloride) in the coal. The salt will be ionized in the heat of the flame, sending caesium ions into the kiln and thus direct contact with the clinker as it is being formed. Here it will become part of the matrix of the clinker and hence the final cement product. All the time the caesium-137 is radioactive.

And it stays radioactive once it is in the finished product, for example in a building or road surface. Its half-life, the time that it takes for half of the caesium-137 to decay to meta-stable barium-137 (emitting radiation as it decays), is unfortunately very well matched to the life-span of concrete buildings at 30.7 years. This means that after about 100 years of building life the building would still be around 10% as radioactive as it was when it was built.

This would certainly be a problem if the coal was highly contaminated. However, a few questions come to mind. Firstly, if the coal contains 20-73 becquerels per kilogramme (Bq/kg) of caesium-137, as has been claimed by Lee In-young, an opposition spokesman for the New Politics Alliance for Democracy party and member of the National Assembly's Environment Labour Committee, why is this a problem when the Japanese legal limit for eating caesium-137 in contaminated vegetables is all the way up at 500Bq/kg? When the most dangerous mechanisms of caesium-137 poisoning relate to accumulation in soft tissue, how can driving along a caesium-137-containing highway constitute a health risk?

Also, the coal may well start the cement making process with 25-73Bq/kg of caesium-137 but the clinker will have a lower level. This is because for every 1t of clinker the plant will typically consume just 100-200kg of coal. The caseium-137 and hence the radiation will therefore be spread out over a larger mass. A level of 50Bq/kg in the coal would translate to a clinker level of 5-10Bq/kg. This is around 100 times lower than the Japanese vegetable limit. After this, the clinker is extended with additives to make cement. This is then added to aggregates and / or sand when concrete or mortars are made, further diluting the caesium-137, perhaps to as low as 1-5Bq/kg. It is arguable that South Korea has received a higher caesium-137 dose from Japan via air and sea than via coal imports.

In light of all this, it appears that those calling for investigations on scientific grounds, like Lee, may be misguided. However, there may be political gain. The histories of Japan and South Korea are long, violent and distrustful. Indeed, according to a BBC World Service poll conducted earlier in 2014, South Korea and China jointly have the most negative perceptions of Japan of all world nations. In this environment stories about radioactive coal become much easier to believe in.

In reality the Japanese vegetable limit is well above the likely levels that might be found in any cement products resulting from the use of this coal. It is consistent with EU limits set more than 20 years earlier (600Bq/kg). A search on the US Environmental Protection Agency's website fails to bring up any formal limit. Instead it states that everyone is exposed to caesium-137 from atmospheric fallout to a low level and that the most dangerous cases are where waste metal processors unwittingly come across sources.

So on the surface then, the South Korean reaction seems like a storm in a teacup. One question remains though. If the caesium-137 levels in the coal are so much lower than the Japanese vegetable limit, why are Korean firms being paid to take it out of Japan?
