As the construction and design industries evolve, so does the demand for sustainable, high-performance building materials. For over 25 years, Thermory has led the way in developing thermally modified wood products that combine the natural beauty of wood with durability and eco-consciousness – offering an ethical, high-performance alternative to tropical hardwoods.
Now more than ever, choosing a better alternative is not just a thoughtful decision –but a necessary one. With new global regulations in play, sourcing tropical hardwoods is becoming increasingly difficult and uncertain.
Since November 25, 2024, imports of Ipe (Handroanthus spp.) and Cumaru (Dipteryx spp.) have required CITES permits and documentation. These popular woods are officially listed under CITES (the Convention on International Trade in Endangered Species) Appendix II.
Simply put, CITES regulates the trade in species that are at risk. It is an international agreement between governments to ensure that international trade in specimens of wild animals and plants does not threaten their survival. Appendix II includes species that are not necessarily threatened with extinction, but for which trade must be controlled to avoid utilization incompatible with their survival.
As of April 25, 2024, 185 parties have joined the convention.
The addition of Ipe and Cumaru to Appendix II is a response to over-harvesting and illegal logging, which have pushed these species toward irreversible ecological loss. With this change, international trade of these species is still allowed, but each shipment must be accompanied by a valid export permit proving legal and sustainable sourcing. If the documentation isn’t in order, shipments may be delayed, confiscated or face heavy fines.
This has immediate effects on availability, costs, and logistics: prices are on the rise, lead times are longer and supply is becoming more limited.
These changes are absolutely beneficial for the environment, but they also raise questions for those who rely on Ipe and Cumaru. What happens if you were planning a project using these materials and now face these new challenges?
Thermory’s thermally modified ash is an excellent alternative to tropical hardwoods.
Thermal modification enhances ash’s natural properties – making it highly resistant to decay and warping – while deepening its naturally warm tones into rich, luxurious hues. With a class 1 decay resistance rating for 25+ years, it’s perfect for long-lasting cladding and decking, ensuring beauty and functionality both outdoors and indoors.
Simply put it’s just as durable, beautiful and high performing as tropical woods, but with none of the sourcing risks or legal complexity.
