Building Materials Guide
Sande plywood confuses a lot of first-time buyers. The name sounds unfamiliar, yet the wood itself is common. This guide breaks down what sande plywood actually is, and where it earns its keep on a job site.
Quick Answer
Sande plywood is a hardwood panel veneered from Brosimum utile, a tree native to Central America and northern South America. US retailers commonly grade and sell it as BCX plywood. Builders choose it for cabinets, shelving, and general construction because it costs less than oak or maple plywood.
Fast Facts
- Botanical name: Brosimum utile
- Family: Moraceae, the mulberry family
- Janka hardness: 810 lbf, between okoume and red oak
- Typical retail grade: BCX (sanded face, exterior-rated glue)
- Conservation status: IUCN "Least Concern," not CITES-listed
What Is Sande Plywood, Exactly?
Sande plywood uses veneer peeled from the sande tree. Its scientific name is Brosimum utile. Wood scientists place it in the mulberry family, Moraceae, according to the USDA Forest Products Laboratory.
Woodworkers also know it as cow tree or palo de vaca, per The Wood Database. The nickname comes from a milky latex the bark produces, once used locally as a milk substitute. Nature clearly has a sense of humor here.
- Common names: sande, cow tree, palo de vaca (The Wood Database)
- Native range: Costa Rica's Atlantic coast down through Colombia and Ecuador (The Wood Database)
- Tree size: 100–130 ft tall, 3–5 ft trunk diameter (The Wood Database)
- Color: pale yellow to light brown, sapwood and heartwood look almost identical (The Wood Database)
Where Does Sande Wood Come From?
Most commercial sande timber ships from just two countries. Pacific Ecuador and Colombia supply nearly all of it, based on data from The Wood Database.
| Property | Detail |
|---|---|
| Native range | Atlantic Costa Rica south through Colombia and Ecuador |
| Main commercial source | Pacific Ecuador and Colombia |
| Tree height | 100–130 ft (30–40 m) |
| Trunk diameter | 3–5 ft (1–1.5 m) |
| Botanical family | Moraceae (mulberry family) |
Key Physical and Mechanical Properties
Sande sits in the middle of the plywood-core pack. It runs denser than okoume, yet lighter than red oak, per figures from The Wood Database.
| Property | Value |
|---|---|
| Average dried weight | 34.6 lbs/ft³ (555 kg/m³) |
| Janka hardness | 810 lbf (3,620 N) |
| Modulus of rupture | 13,760 psi (94.9 MPa) |
| Elastic modulus | 2,124,000 psi (14.65 GPa) |
| Crushing strength | 8,300 psi (57.2 MPa) |
Higher numbers mean better dent resistance. By that measure, sande holds its own against several traditional plywood cores.
Sande Plywood Grades Explained
US retailers usually sell sande as BCX plywood, confirmed by Home Depot's product listings. Each letter in that code tells you something useful.
- B-grade face: smooth and sanded, with only small, tight knots or patches (Vinawood)
- C-grade back: rougher, allows visible knots, and usually stays hidden (TT Plywood)
- X-rated glue: an exterior-type adhesive that resists moisture, though the panel itself is not waterproof (Vinawood)
Think of BCX as business casual for plywood. One side dresses up for the room, and the other side just does the structural work.
| Grade | Face | Back | Glue | Typical Use |
|---|---|---|---|---|
| BCX | B (smooth, sanded) | C (rougher, hidden) | Exterior (X) | Cabinets, shelving, painted panels |
Sande vs. Other Plywood Core Species
Buyers often compare sande with okoume and meranti. All three come from tropical hardwood trees, yet each behaves differently on a bench.
| Species | Scientific Name | Janka Hardness | Density | Typical Use |
|---|---|---|---|---|
| Sande | Brosimum utile | 810 lbf | 34.6 lbs/ft³ | Cabinets, general construction |
| Okoume | Aucoumea klaineana | 400 lbf | 27 lbs/ft³ | Lightweight boatbuilding |
| Dark Red Meranti | Shorea spp. | 800 lbf | 42 lbs/ft³ | Marine plywood, joinery |
Okoume wins on weight, since it works well for hulls that need to stay light. Meranti wins on density for heavy marine duty. Sande lands in between, as a solid, budget-friendly middle option.
Common Uses of Sande Plywood
Sande plywood shows up across plenty of everyday projects. The USDA Forest Products Laboratory lists these applications for the species.
- Plywood face and back veneers
- Particleboard and fiberboard components
- General carpentry and light construction
- Furniture components
- Pulp for paper production
Because retailers usually grade sande panels as BCX, the sheets also pick up that grade's typical construction roles, per Vinawood's BCX guide:
- Wall sheathing and roof decking
- Subflooring and underlayment where one smooth face matters
- Concrete formwork, for a reasonably smooth finish
- Painted cabinet boxes and built-ins
A Note on Boatbuilding
Some hobby boatbuilders use sande as a stand-in for meranti or virola, according to Hood Distribution, a plywood importer. However, sande's non-durable decay rating means standard sheets don't meet the BS 1088 marine plywood standard, which requires decay-resistant veneers tested through Lloyd's Register. Treat it as a budget hobby material, not a certified marine panel.
Is Sande Plywood Durable? Moisture and Rot Resistance
Sande wood is not naturally rot-resistant. The USDA Wood Handbook rates it non-durable against decay, stain, and insects.
- USDA Wood Handbook: non-durable, requires care to prevent stain and decay damage
- ITTO Tropical Timber Atlas: Class 5, "non-durable" against fungal decay
- ITTO rating: Class 5, susceptible to dry wood borers and termites
(All three ratings cited via The Wood Database.)
That's why builders usually keep sande plywood indoors. For outdoor or damp use, seal every face and edge first.
Formaldehyde, Safety, and Emission Standards
Plywood adhesive can release formaldehyde over time. US law now limits how much any hardwood plywood may emit.
- Since March 22, 2019, hardwood plywood sold in the US must carry a TSCA Title VI compliance label (US EPA)
- Earlier stock could instead carry a CARB Phase 2 label, which the EPA treats as equivalent (US EPA)
- Look for the compliance stamp along the panel's edge before you buy
Is Sande Plywood Sustainable?
Sande scores reasonably well on conservation status. That matters if you care where your lumber comes from.
- Not listed in the CITES Appendices (The Wood Database)
- Rated "Least Concern" on the IUCN Red List (The Wood Database)
- Compare that to okoume, which the IUCN rates "Vulnerable" (The Wood Database)
That combination makes sande a comparatively low-risk import choice, at least on paper.
Sande Plywood: Pros and Cons
| Pros | Cons |
|---|---|
| Costs less than oak or maple plywood | Not rot-resistant without sealing |
| Smooth, sandable BCX face | Tension wood can pinch saw blades |
| Uniform, light color throughout | No BS 1088 marine certification |
| Glues, stains, and finishes well | Sapwood can stain if not dried quickly |
| Not CITES-listed; low conservation risk | Coarse texture needs sharp tools |
How to Buy Sande Plywood: Practical Tips
- Check the grade stamp on the panel edge for BCX or an equivalent rating
- Confirm the glue rating (Exterior or Exposure 1) matches your project's moisture exposure
- Look for a TSCA Title VI or CARB Phase 2 label if indoor air quality matters (US EPA)
- Expect standard sheet sizes of 4×8 ft, plus smaller project panels at most stores
- Buy a little extra, since interlocked grain can leave a fuzzy surface when cut (The Wood Database)
Frequently Asked Questions
Is sande plywood the same as birch plywood?
No. Birch plywood comes from Betula species, not Brosimum utile. Birch also runs harder, at roughly 1,260 lbf on the Janka scale.
Is sande plywood waterproof?
No, standard sande plywood is not waterproof. The exterior-rated glue resists moisture, but it does not survive full submersion.
Can I use sande plywood outdoors?
Only with sealing, paint, or another protective finish. Untreated sande decays faster than naturally durable hardwoods, per the USDA Wood Handbook.
Is sande plywood good for cabinets and furniture?
Yes, especially painted cabinets and shelving. It glues, sands, and finishes well, according to The Wood Database.
Key Takeaways
- Sande plywood comes from Brosimum utile, a Central and South American hardwood
- US retailers commonly grade and sell it as BCX plywood
- Janka hardness sits around 810 lbf, between okoume and red oak
- It is not naturally rot-resistant and lacks BS 1088 marine certification
- It carries an IUCN "Least Concern" rating and no CITES listing
Sande plywood won't win any marine pedigree contests. But for cabinets, shelves, and everyday builds, it earns its keep, one budget-friendly sheet at a time.
