Gypsum industry news

Mexico: Researchers at the National Autonomous University of Mexico have developed Sargapanel, a sargassum seaweed-based alternative wallboard. The team says that Sargapanels can replace traditional gypsum-based boards and tiles in wall and ceiling applications. It can also help to clear Mexico’s Caribbean beaches of the common organic deposit.

US: The National Association of Home Builders (NAHB) says that more than 71% of the US’ total annual imports of gypsum originate in Mexico. The association has highlighted the possibility of ‘scarcity and an acute, sustained rise in building materials costs’ as a result of new tariffs. The US government imposed 25% duties on products from Mexico and fellow North American country, Canada, on 4 March 2025.

NAHB said that it will ‘continue to seek a tariff exemption for building materials.’

Mexico: Saint-Gobain has entered into a definitive agreement to acquire construction chemicals producer Ovniver Group for US$815m. The parties expect to conclude the deal in early 2025. Ovniver Group produces its CeMix brand adhesives, renders, surface preparations and waterproofing products across 16 sites in Mexico, Guatemala, Honduras and the US.

Ovniver Group recorded revenues of US$285m in 2023, with an average annual growth rate of 20% over the past five years.

US: US gypsum wallboard sales grew by 1% year-on-year to 628Mm² during the first quarter of 2024. The country imported 20.1Mm² of gypsum wallboard, down by 13% year-on-year. Mexico supplied 19.3Mm² (96%) and Canada 800,000m² (4%) of imports. Meanwhile, the US exported 19.1Mm² of gypsum wallboard during the quarter, 18Mm² (94%) of it to Canada.

US: The US Geological Survey reported domestic natural gypsum production volumes of 16.3Mt during the first nine months of 2023, down by 0.3% year-on-year from 16.4Mt during the corresponding part of 2022. Meanwhile, calcined gypsum production volumes grew by 1.2%, to 14Mt from 13.8Mt. Throughout the period, the US imported 5.91Mt of crude gypsum, up by 35% year-on-year. Spain supplied 2.4Mt (41%) of imports, followed by Mexico with 1.7Mt (29 %) and Canada with 1.56Mt (26%).

US: Data from the United States Geological Survey (USGS) show that the sale of gypsum board products fell by 5% to 1.25Bnm² in the first half of 2023, from 1.31Bnm² in the same period in 2022. The total supply of crude gypsum grew by 9% to 20.4Mt. Notably, supplies of imported and synthetic gypsum increased in the reporting period. However, the USGS noted that on a quarterly basis “...variances are often the result of differences in weather conditions, which can impede or encourage construction activities, coupled with market demands that are often driven by residential and commercial building activity. Use of uncalcined gypsum remained stable, but consumption of calcined gypsum fell by 33% to 7.86Mt, due to reduced utilisation in board products. Spain, Canada and Mexico remained the main sources of import of crude gypsum. However, imports from Türkiye more than doubled to 195,000t.

Mexico: Panel Rey’s El Carmen gypsum wallboard plant near Monterrey has been awarded a clean industry certification by the Federal Attorney for Environmental Protection (PROFEPA). The acknowledgement recognises that the plant operates in full compliance with legal regulations at the federal, state and municipal level. It also demonstrates environmental performance, shows a voluntary commitment to the protection and conservation of the environment and includes social responsibility awareness. The certificate has a duration of two years and will last until 2025.

US: The US gypsum wallboard industry produced 623Mm² of gypsum wallboard during the first quarter of 2023, down by 1% year-on-year and by 1.2% quarter-on-quarter. The industry exported 20.1Mm² of gypsum wallboard in the quarter under review, corresponding to 19% year-on-year growth. Canada received 19Mm² of the product, 94% of total exports for the quarter.

United States Geological Survey (USGS) data show 4% year-on-year growth in US gypsum wallboard imports. The country imported 23Mm² during the year, 20.9Mm² (91%) of it from Mexico and 1.84Mm² (8%) from Canada. Total calcined gypsum consumption was 4.66Mt in the US in the first quarter of 2023, up by 9.9% year-on-year from 4.24Mt in the first quarter of 2022.

Gypsum wallboard or drywall got name-checked by the commander-in-chief of the US last week. President Joe Biden announced during his State of the Union Address to the US Congress on 7 February 2023 that he was going to require that, “all construction materials used in federal infrastructure projects to be made in America.” He then expressly mentioned wallboard along with lumber, glass and fibre-optic cables before adding the catchy sound-bite, “American roads, bridges, and American highways are going to be made with American products as well.” Although for the wallboard sector he might as well have been saying that American walls are going to be made from American wallboard.

Biden’s focus on gypsum wallboard and other building materials is linked to the US$1.2Tn Infrastructure Bill that was signed in late 2021. The White House Office of Management and Budget (OMB) issued guidance in mid-2022 on how the spending should be targeted at US manufactured construction materials. At that time it excluded steel, cement, aggregates and additives but included non-ferrous metals, plastic and polymer-based products, glass, lumber and wallboard in its category of ‘construction materials’ that should be sourced locally. Its definition of ‘construction materials’ meant that the manufacturing process for the construction material occurred in the US. Although combining some of the materials above as a composite would then be classified as a ‘manufactured product,’ at which point, 55% of the total costs of the components would have to be mined, produced or sourced in the US to meet the so-called ‘Buy America’ preference. The new bit following Biden’s recent speech is that the OMB has released further guidance for the ‘construction materials’ mentioned above. So far, so much legalese.

Canada-based manufacturers of building materials are understandably wary of this kind of talk. However, ‘Buy America’ has been around since the 1930s and there have often been ways around it. As Jean Simard, the president and chief executive officer of the Aluminium Association of Canada, told CBC, in practical terms, the math is on Canada's side. "Canada represents about 70% of total US imports. That's not going to change."

Data on how much wallboard is actually exported from Canada to the US is hard to find but the former’s wallboard sector is about 10 times smaller than the latter’s. Most of the gypsum producers in Canada are owned by international companies with a presence in the US also. This created an interesting situation in October 2022 when CertainTeed Canada welcomed the Canadian International Trade Tribunal's ruling in favour of six provinces and territories' anti-dumping measures on imports of gypsum wallboard from the US. CertainTeed is owned by France-based Saint-Gobain, which also runs Continental Building Products. Together, Saint-Gobain is the second largest wallboard producer in the US by installed capacity. It seems unlikely that the current US rhetoric will reduce Canada’s exports of crude gypsum south of the border. Data from the United States Geological Survey (USGS) shows that the US imported 1.57Mt of crude gypsum from Canada in the first nine months of 2022, an increase of 12% year-on-year from the same period in 2021. Imports from Mexico had been similar so far in 2022, although they are down compared to 2021.

The other reason Biden may have mentioned wallboard specifically in a patriotic speech may have been in relation to the long-running defective China-based wallboard story from the early 2000s. Although the legal cases associated with this have mostly died down, one popped up in early February 2023 when Knauf and its China-based subsidiaries managed to avoid a product liability claim because the Florida-based plaintiff had waited too long. Knauf now owns the US’ largest wallboard producer, USG.

It is worth remembering that the US remains the largest wallboard market in the world by production capacity. So calls by a politician to ‘Buy America’ may be more for the ears of voters rather than industry. Although that’s not to say that the situation won’t change in the future. The examples above also show that the US may have been guilty of dumping wallboard upon its neighbours and that the two largest producers in the US are both foreign owned. The other thing that Joe Biden said in his State of the Union Address was that buying American was “totally consistent with international trade rules.” This comment may have been made in response to European criticism of some of the implications of the Inflation Reduction Act with its incentives for industrial supply chains supporting renewable energy production and electric vehicles, be they based in the US or in ‘friendly’ countries. The wallboard sector seems unlikely to be caught up in this directly but protectionism is in the air. How this manifests in corporate strategy over the next few years may be telling.

US: Total sales of gypsum boards products grew by 2% year-on-year to 1.99Bnm² in the first nine months of 2022, from 1.94Bnm² in the same period in 2021. Sales grew particularly fast in the South Atlantic and East South Central regions, but they fell in the Pacific region. Data from the United States Geological Survey (USGS) shows that the total of uncalcined gypsum used in the reporting period rose by 5% to 15.7Mt and the total of calcined gypsum used increased by 2% to 17.9Mt. The supply of mined crude gypsum fell by 6% to 15.9Mt, imports rose by 1% to 5.11Mt and the supply of synthetic gypsum remained stable at 9.75Mt. Spain became the biggest source of crude gypsum imports so far in 2022 followed by Canada, Mexico and Türkiye.
