“Total committed” only includes those mills which, as far as we are aware, are definitely going ahead. The €150m investment, which will utilise


recycled wood, will give an estimated capacity of 360,000m3


. Industry publication EUWID has reported


an OSB project by Tartak Olczyk based in Krsocin. Some construction work had apparently started in 2025, but, like many other projects, there have been no updates on further progress, which may be due to the economic background. Looking at Russia, our list of future capacity has had a number of projects listed. We have updated the listing for Verkhovazhsky, Vologda Regio. The Vologda region government has confirmed that wood processor Biolesprom LLC is the name behind the project and plans to set up production capacities for 60,000m³ of OSB boards and 90,000m³ of sawn timber. The Vologda region is one of the richest regions of Russian Federation and the forests there are significant for economic development. As previously reported, Angara Les LLC, part of the Karat Group, plans to build the region’s first and largest OSB plant beyond the Urals. The company has stated on its website that the total area of all production facilities will be approximately 10 hectares and that the new facility will reach full production capacity in 2027. Investment in the project will total 3.1 billion rubles and more than 400 new jobs would be created. “The low-rise housing market is currently transitioning to an industrial phase, namely,


the production of standardized house kits,” said Sergey Tarasyuk, Director of Angara Les LLC.


“This will be the largest production facility in Russia east of the Urals,” he added. We have updated the expected completion


date in Table 2. A OSB extension project at the existing mill in Ufa, previously operated by Kronospan, has now been removed from the future capacity listing. Kronospan withdrew its operation of the plant several years ago [and its other Russian plants] – placing it under the control of the Causa Foundation and run by the plant management. A couple of other Russian OSB


investments are also listed - Sibboard in Siberia and OOO DOK Kalevala in Petrozavodsk, Karelia province. The only update to either is the latter and that purely relates to repair work undertaken following a fire in 2024. A Chinese machinery supplier was involved in this. The original technology supplier Siempelkamp is not supplying to Russia due to the Ukraine conflict.


ASIA AND REST OF THE WORLD Moving further afield, UltraDecor in Kazakhstan continues with its ambitions of becoming the world’s No.2 wood-based panel manufacturer by 2030. It already has an OSB plant in Ufa City. The new plant is being supplied by Yalian with an estimated capacity of 660,000m3


.


In an Interfax news report in April 2026, the Kazakh Government reportedly approved


the signing of an investment agreement with Ultradecor Trading Kazakhstan LLP for the project.


The project, costing more than US$150m, is planned to be built in 2026-2028. About 50% of output will go to the domestic market. After reaching 80% of design capacity, exports could reach 60,000m3 Moving continents, Chile is seeing some


.


OSB investment in South America. The Dieffenbacher contract with Paneles Arauco SA (Santiago de Chile) to convert one of its two Trupan MDF lines in Cholguán in the Bío Bío region to making OSB is scheduled to start production in the second half of 2026. The plant will have an estimated planned capacity of 300,000m3


and is being built


around the existing 10-opening press from 1988.


Another potential project to look out for


is a second OSB line for Chile Panel SA, which according to EUWID is considering a project. We will wait to hear more before adding this to the future capacity list. Finally, on the other side of the world at


the Fletcher Building’s Laminex site at Taupo, an OSB project is scheduled to complete in early 2027. Civil works commenced back in 2023.


The production line, with a 130,000m3 capacity, will supersede the current particleboard line which will be decommissioned. Dieffenbacher is the main technology supplier, with the CEBRO plant producing both conventional OSB and Fine OSB.
