Understanding the goods

Indonesian furniture woods, explained.

Indonesian furniture uses half a dozen timbers with genuinely different properties and prices. The choice is decided by where the piece will live, how long it has to last, and whether anybody will maintain it. Appearance is the worst basis for the decision and the most common one.

Six timbers.

All of these are grown in Indonesia and all carry the same legality documents. What separates them is what they do once the piece leaves the workshop.

Teak
Natural oils and silica let it stand outdoors untreated for decades. Grown on long-rotation plantations, priced accordingly, and the grade question is how much sapwood the piece contains, because sapwood has none of the durability.
Acacia
A fast plantation hardwood that looks like teak when new and behaves nothing like it outdoors. Excellent value indoors and under cover, and it needs a maintained finish to survive exposure.
Mahogany
Plantation-grown in Java, stable and fine-grained, and it takes a finish beautifully. An interior timber, and species listings apply to some mahoganies so the botanical name belongs on the order.
Suar
Also called monkeypod or raintree. Grows very large, which is why it is the timber behind wide single-slab tables. Dramatic figure, and slab work lives or dies on how the drying was done.
Albasia
Very fast growing and very light, and the raw material for barecore panels rather than for solid furniture. Cheap and soft, and it is a component timber.
Mango
A by-product of orchards past fruiting, dense and often figured. Inexpensive, interesting, and variable because the trees were never grown for timber.

The decision that actually matters.

Not the species. The moisture content. A piece built at tropical equilibrium and delivered into a heated European or North American interior gives up water for weeks, and the movement opens joints and splits panels. This is the most common claim on Indonesian furniture and it applies to every timber on the list.

Specify the target moisture for your market, have it measured at loading with an instrument, and put it in the contract. A workshop with a kiln can hit a number and a workshop drying in the open air often cannot, and knowing which you are dealing with is worth more than the species conversation.

What the paperwork does not care about.

Indonesian timber legality applies to all of them equally, and the European deforestation regulation reaches all of them from December 2026. There is no cheaper documentary route for the cheaper wood, which surprises buyers who assumed the rules were about tropical hardwood specifically.

For the United States, the Lacey declaration needs the botanical species in Latin on every plant-product entry, and that includes finished furniture. Ask for scientific names at quotation stage, because a supplier who cannot supply them has given you something you cannot file.

Questions buyers ask.

Is acacia a cheap substitute for teak?

It is a different timber for a different job. Outdoors and unmaintained, teak survives and acacia does not, and that gap is what the price difference buys. Indoors or under cover with a finish somebody maintains, acacia is genuinely good value rather than a compromise.

Why do suar slab tables crack?

Because a wide slab moves a great deal as it loses moisture, and a slab that was not dried properly finishes drying in your customer's dining room. Kiln drying, correct thickness and a moisture specification are the whole answer, and it is worth paying for.

Do I need to name the species in Latin?

For the United States, yes, on every plant-product entry. For Europe from December 2026 you need traceability back to the plot. In both cases the information comes from the producer, and asking for it at quotation stage rather than at shipping stage saves a great deal of trouble.
