A New Era for Architects and Builders: The Shift Away from Ipe and Cumaru

Starting November 25, 2024, sourcing Ipe (Handroanthus spp.) and Cumaru (Dipteryx spp.)—the coveted hardwoods known for their strength and beauty—will become a lot more complicated. These popular woods, long trusted for their durability and aesthetic appeal, will be officially listed under CITES (the Convention on International Trade in Endangered Species) Appendix II. This means stricter regulations on international trade, new paperwork, and potential delays, fines, and rising costs for those trying to import them into the U.S and Canada. 

But here’s the good news: there’s a stunning, sustainable product that’s just as durable, versatile, and beautiful—Thermory Benchmark Ash. Say goodbye to sourcing nightmares and hello to a material that blends performance, aesthetics, and eco-consciousness—without the legal headaches.

Keep reading to see why Thermory Benchmark Ash could be the ideal material for your next project.

Why CITES is a Game-Changer

The addition of Ipe and Cumaru to CITES Appendix II is a direct response to over-harvesting and illegal logging, which have pushed these species to the brink of irreversible ecological loss. With these new regulations, any imports of these woods into the U.S. must come with documentation proving their legal and sustainable sourcing. If the paperwork’s not in order, shipments can be delayed, confiscated, or subject to hefty fines. As of November 2024, these woods will no longer just be “luxury materials”—they’ll be a logistical (and environmental) minefield.

On top of the legal red tape, shipping delays and port strikes in Brazil have already put a strain on the supply chain, sending costs soaring. In an industry where timing and budget are everything, these challenges can create serious headaches for architects and builders.

The Real Cost of Ipe and Cumaru

Board scrap pile

By the end of November 2024, if you’re still sourcing Ipe and Cumaru, be ready for paperwork pains, possible delays, and higher costs. The need for proper CITES documentation means you could be dealing with supply chain disruptions and the risk of penalties if you can’t prove your wood’s legality. Not exactly the best way to keep your project on schedule.

So, what’s the solution? Look for alternatives that offer the same performance without the risk. Enter Thermory Benchmark Ash.

No More Sourcing Stress (with Thermory Benchmark Ash)

If you’re tired of navigating the complex world of exotic hardwoods, Thermory Benchmark Ash offers all the benefits of Ipe and Cumaru with none of the sourcing and legal challenges. Here’s why:

  1. Sustainably Sourced (and Straight Forward)
    Unlike Ipe and Cumaru, which have been closely linked to deforestation, corruption, and unsustainable logging practices, Thermory Benchmark Ash is sustainably sourced from well managed forests. No need for complicated paperwork or worrying about where your wood came from. Plus, it’s traceable, so you can feel good about every board you use.

  1. Durability Without the Hassles
    Thermory Benchmark Ash holds up just as well as Ipe and Cumaru. It’s rot-resistant, moisture-resistant, and pest-resistant—all thanks to a chemical-free thermal modification process that enhances the wood’s natural strength. Whether you’re using it for decking, cladding, or landscaping, you get the same longevity and minimal maintenance that you expect from tropical hardwoods.

  1. Natural Beauty That Lasts
    Ipe and Cumaru are loved for their rich, dark hues, but Thermory Benchmark Ash brings a similar natural, golden-brown color that ages beautifully into a soft, silver-gray patina. No need for constant oiling or chemical treatments—just pure, natural beauty that gets better with time.

  1. Low Environmental Impact
    Thermory Benchmark Ash is sourced from local forests in Europe and North America, reducing the carbon footprint of shipping heavy exotic woods from South America. Plus, the thermal modification process is completely chemical-free, so you can rest easy knowing your materials are both sustainable and non-toxic.

  1. A Supply Chain You Can Count On
    With international trade headaches looming over Ipe and Cumaru, Thermory Benchmark Ash offers a more predictable and reliable supply chain. It’s less likely to face disruptions from strikes, port delays, or regulatory changes. That means more control over your project timeline.

The Smart, Sustainable Choice

As the building world faces new challenges with Ipe and Cumaru, Thermory Benchmark Ash offers an easy way forward. It’s just as durable, beautiful, and high performing, but with none of the sourcing risks or legal complexity. Whether you’re designing a sleek modern home or a high-end commercial space, Thermory Benchmark Ash delivers top-tier performance and timeless aesthetics without the drama.

Chris Keith from Mason’s Mill perfectly summed up the growing importance of high-quality, reliable materials:


“From the start of this project, with the attention to detail and Thermory Ash selected as the material by the architect, I knew this would be something special. Timelines are always tight with commercial projects, which makes having dedicated teams on both sides of the construction process so important. Mason’s Mill & Lumber, along with Thermory USA, brought exceptional service and innovative architectural materials together, bringing the architect’s vision to life. Projects like the Balboa Surf Club highlight the design, material, and construction efforts on all sides, resulting in the final product you see today. Can’t wait for the next one!”

If you want to stay ahead of the curve and future-proof your projects, Thermory Benchmark Ash is your go-to material for sustainability, durability, and stunning looks.
