Kra Nhuong: Cambodia's Other Vanishing Rosewood
There is a stretch of semi-deciduous forest in Cambodia's northeast where two of the world's most valuable timbers once grew side by side. One was Neang Nuon. The other was Kra Nhuong. Both are rosewoods. Both are Critically Endangered. Both have been logged, smuggled, and traded with such intensity that mature trees are now almost impossible to find in the wild. If you have heard of Neang Nuon, you have probably heard of Kra Nhuong as well. They are often mentioned together, sometimes confused with one another, and both are protected under Cambodian law. This article explains what Kra Nhuong is, why it matters, and why Khmer Wood Design does not sell it.
What Is Kra Nhuong?
Kra Nhuong is the Khmer name for Dalbergia cochinchinensis, known internationally as Siamese Rosewood, Thailand Rosewood, or Vietnamese Rosewood. It is a large tree, reaching 20 to 30 metres in height with a trunk diameter of 60 to 100 centimetres. It grows in mixed deciduous and dry evergreen forests at altitudes between 100 and 800 metres, across Thailand, Cambodia, Laos, and Vietnam. It flowers from June to July and fruits from September to November.
The heartwood is the reason for its value. It is a medium to dark reddish brown, streaked with darker brown and black. The sapwood is pale yellowish white, sharply separated from the heartwood. The grain is straight to slightly interlocked, with a medium to fine uniform texture and good natural luster. Historically it was used for the finest furniture, musical instruments, decorative carving, and turned objects. In Vietnam it is classified as a "first class prime timber" because it is hard, durable, easy to work, and resistant to insects and termites.
The Numbers Behind the Wood
Kra Nhuong has a Janka hardness of 2,430 lbf, which is 10,790 Newtons. Its average dried weight is approximately 1,035 kilograms per cubic metre. Its modulus of rupture, which measures bending strength, is 171.0 MPa. Its modulus of elasticity is 16.38 GPa. Its crushing strength is 117.0 MPa. It shrinks approximately 2.04 percent radially and 4.79 percent tangentially as it dries, giving a tangential-to-radial ratio of about 2.1. Some sources list its density as high as 1,080 kilograms per cubic metre, which means the wood is denser than water.
For a furniture buyer, these numbers describe a timber that is extraordinarily hard, heavy, and stable. A Janka hardness of 2,430 lbf places it well above teak at 1,155 lbf and more than double black walnut at 1,010 lbf. A table made from Kra Nhuong would be almost impossibly heavy, and it would outlast the building it stood in. The low shrinkage figures mean it moves predictably once dried rather than twisting or warping. This is wood that behaves, because it has spent decades growing slowly and tightly.
Sourcing and Conservation
Here is the part that matters most. Kra Nhuong is classified as Critically Endangered on the IUCN Red List, with a decreasing population trend. It is listed on CITES Appendix II, which means its international trade is strictly controlled and requires export permits. In Cambodia, the harvesting of rare tree species was prohibited under Forestry Law No. 35 in 2002. A ban on the export of logs was issued in 1996. Trade and circulation of all rosewood, including Kra Nhuong, was banned outright on 23 February 2013.
The illegal trade has continued regardless. A CITES report documented cases of rosewood being smuggled across the Thai and Vietnamese borders, often with the involvement of officials. In one case, military police were caught accepting bribes to help loggers cross into Vietnam. In another, three military trucks were seized transporting illegally logged rosewood in Thong Khmum province. The destination for most of this timber is China, where rosewood furniture commands extraordinary prices. An estimated 80 percent of the species has been lost over the last 150 years.
It is important to understand the relationship between Kra Nhuong and Neang Nuon. They are closely related rosewood species. Both are Critically Endangered. Both are CITES-listed. Both are protected under Cambodian law. They are sometimes confused in trade, and some unscrupulous dealers use the confusion to sell one as the other. If you are offered either species, you should be deeply sceptical of its provenance.
Is Kra Nhuong Good for Furniture?
Technically, it is superb. It is harder than almost any commercially available timber. It is dense, stable, insect-resistant, and takes a finish that few woods can match. It was historically prized for high-end cabinetry, musical instruments, and decorative carving. The Chinese hongmu furniture market drove much of the demand that emptied Cambodia's forests of this species.
But its quality is precisely the problem. The very characteristics that make Kra Nhuong desirable made it a target for illegal logging on an industrial scale. A tree that takes 20 to 30 years to reach a size suitable for harvesting cannot survive a market that wants it immediately. Reforestation and breeding programmes for the species have been slow to gain attention, mainly because of its slow growth rate. Owning a genuine piece of Kra Nhuong is not a commodity purchase. It is a responsibility.
How Kra Nhuong Compares
If you are looking for a dark, dense hardwood for a statement piece, there are sustainable alternatives that deliver similar qualities without the ethical burden.
Thnong (Burma Padauk) is the closest available substitute. It is a rosewood-adjacent species with a rich reddish-brown heartwood, good density, and excellent durability. It has a radial shrinkage of 3.78 percent and a tangential shrinkage of 5.61 percent, giving a tangential-to-radial ratio of 1.48, which is better than Kra Nhuong's 2.1. It is more available than Kra Nhuong, though still a luxury timber. It does not have the same legendary status, but it is a legitimate, beautiful wood that can be sourced responsibly.
Teak is the standard against which tropical hardwoods are measured. It is naturally oily, resistant to insects and moisture, and stable in service. It is more expensive than Thnong but widely available from plantations. For outdoor furniture or pieces that will see heavy use, teak is the better choice. Kra Nhuong is harder, but teak is more practical.
Beng is another Cambodian luxury wood, with rich colour and beautiful burls that command high prices. It is also endangered and restricted, so the same cautions apply.
None of these woods match Kra Nhuong's hardness or its legendary status. That is precisely why Kra Nhuong should be left alone.
How We Work With Kra Nhuong
Khmer Wood Design does not sell new Kra Nhuong. We do not buy it. We do not accept commissions that require it. If a customer asks for it, we explain why we will not work with it and offer sustainable alternatives.
The only exception is reclaimed timber from pre-owned furniture or heritage pieces where the provenance is documented. If a client owns an antique Kra Nhuong piece that is being restored, we can work with that existing timber. We require proof of origin, such as old receipts, family records, or photographs of the piece in its previous setting. If the provenance is unclear, we decline the work.
We refuse to work with undocumented timber because there is no way to know whether it was legally harvested. The illegal rosewood trade has fuelled violence, corruption, and environmental destruction across the region. A workshop that claims not to know where its timber came from is either lying or negligent. Our green policy commits us to reclaimed wood wherever the piece allows it, and to honesty about what we cannot source responsibly.
Care and Maintenance of Kra Nhuong
If you own a genuine Kra Nhuong piece, whether an antique, a family heirloom, or a documented original, treat it with the care it deserves. The wood is dense and stable, but old pieces may have developed cracks or joint failures over decades of use. Do not attempt to repair them yourself. Professional restoration is essential for heritage pieces of this value. Clean only with a soft, dry cloth. Avoid all moisture, direct sunlight, and household cleaners. If the finish is worn, consult a specialist restorer who understands dense tropical hardwoods.
One specific warning: rosewoods in the Dalbergia genus are known sensitizers. Although severe reactions are uncommon, Kra Nhuong has been reported to cause skin irritation, rashes, or hives in some individuals. If you are working with the wood, or if you own a piece and notice a reaction, take it seriously. Wear gloves when handling raw timber, and keep the finished surface sealed.
Sustainable Alternatives
If you want a piece that captures the spirit of Kra Nhuong, dark, rich, durable, and beautiful, without contributing to the destruction of an endangered species, we can help. We work with Thnong, Teak, and reclaimed Cambodian hardwoods. We can finish them to evoke the deep tones of rosewood without the ethical cost. The result will be a piece you can be proud of for reasons that go beyond its beauty.
FAQs
Can I buy new Kra Nhuong? No. It is Critically Endangered, CITES Appendix II listed, and protected under Cambodian law. Trade and circulation of all rosewood was banned in Cambodia on 23 February 2013. If someone offers you new Kra Nhuong, the timber is almost certainly illegal.
How do I know if a piece is genuine? Provenance is everything. Look for documented history, such as old photographs, receipts, family records, or CITES paperwork where applicable. Without documentation, you cannot know whether a piece is genuine or whether it was legally acquired.
What is the difference between Kra Nhuong and Neang Nuon? They are closely related rosewood species, both Critically Endangered and CITES-listed. Kra Nhuong is Dalbergia cochinchinensis. Neang Nuon is Dalbergia oliveri. Both are almost gone from Cambodia's wild forests. The names are sometimes used interchangeably in illegal trade.
Is it legal to own an antique Kra Nhuong piece? Ownership of pre-existing pieces is generally legal, but the burden of proof is on the owner. If you cannot demonstrate that the piece predates the trade restrictions, you may face questions. Document everything.
What is a sustainable alternative? Thnong, also known as Burma Padauk, is the closest available substitute, with a similar rich colour and good durability. Teak is excellent for outdoor use. Reclaimed rosewood from documented sources is also an option, though increasingly rare. Contact us to discuss which wood suits your project.
