Acacia auriculiformis (yellow wattle acacia) is classified as durability class IV under Vietnam’s national wood grading standard - a mid-range class that combines manageable weight, good load-bearing strength, natural resistance to termites and moisture, and a stable domestic supply chain. This article explains what class IV means, how the three acacia species compare, and why acacia auriculiformis supplies roughly 70-80% of all wood pallets made in Vietnam.
1. What is acacia wood?
Acacia wood is a natural hardwood harvested from acacia trees, a genus in the legume family (Fabaceae). The tree grows widely across Vietnam, is fast-growing, and tolerates harsh climatic conditions well. It delivers economic value across manufacturing, construction, and logistics industries.
1.1 Origin and biological characteristics
- Origin: Acacia originates from Australia and Southeast Asia. In Vietnam it is cultivated extensively in the Central and Southern regions - Quang Ngai, Binh Dinh, Dong Nai, and the Central Highlands provinces.
- Tree dimensions:
- Height: Mature trees reach 15-25 m.
- Trunk diameter: 20-50 cm depending on growing conditions.
- Leaves: Lance-shaped, long, glossy green - well adapted to dry conditions.
- Flowers: Bright yellow flowers grow in clusters, blooming mainly in summer.
1.2 Which durability class does acacia belong to?
Under Vietnam’s national wood classification table, acacia is durability class IV. Class IV wood is characterised by:
| Property | Class IV description |
|---|---|
| Weight | Medium - not excessively heavy, easy to transport and machine |
| Structural strength | Good load-bearing capacity, withstands harsh weather |
| Economic value | Suited for industrial and domestic products with a stable supply |

3. Acacia auriculiformis in pallet production
Acacia auriculiformis is the dominant raw material for wood pallet manufacturing in Vietnam, accounting for approximately 70-80% of market share.
Why is acacia auriculiformis preferred for pallets?
| Factor | Detail |
|---|---|
| Load-bearing strength | Handles heavy loads and meets strict requirements in warehousing and freight |
| Moisture and pest resistance | Natural oils extend pallet service life in cold storage and humid environments |
| Domestic supply | Planted widely in Vietnam with a short harvest cycle of 7-10 years - raw material is consistently available |
| Competitive price | Lower cost than imported pine or rubberwood |
4. Acacia auriculiformis vs. other wood pallet materials
| Criterion | Acacia auriculiformis | Pine (imported) | Rubberwood |
|---|---|---|---|
| Durability class (Vietnam) | Class IV | Class V-VI | Class V |
| Hardness | High | Medium | Medium |
| Natural pest resistance | Good (essential oils) | Low - needs treatment | Low - needs treatment |
| Domestic supply | Abundant | Imported - less stable | Moderate |
| Price per pallet | Competitive | Higher (import cost) | Similar to acacia |
| Market share in VN pallets | ~70-80% | ~10-15% | ~5-10% |
Market share figures are estimates based on industry observation. Acacia auriculiformis dominates because it combines strength, natural pest resistance, and low cost in a single locally grown species.

Frequently asked questions about acacia wood durability class
1. Which durability class is acacia auriculiformis?Acacia auriculiformis (yellow wattle) is durability class IV under Vietnam’s national wood classification standard. Class IV indicates medium weight, good structural strength, and reasonable resistance to weathering and pests.
2. What are Vietnam’s wood durability classes?Vietnam’s standard runs from class I (most durable, e.g. ironwood) through class VIII (least durable, e.g. soft plantation species). Classes I-III are premium hardwoods, classes IV-V are mid-range commercial woods, and classes VI-VIII are soft or fast-growing species with limited structural use.
3. Is class IV wood suitable for pallets?Yes. Class IV combines adequate load-bearing capacity, manageable weight for machining, and natural pest resistance from essential oils. These three properties make it the most common pallet wood in Vietnam.
4. Why does acacia auriculiformis resist termites naturally?The wood contains natural essential oils that are toxic or repellent to termites and wood-boring insects. This reduces the need for chemical treatment and extends pallet service life in humid or outdoor environments.
5. How does acacia auriculiformis compare with imported pine for pallets?Acacia auriculiformis has higher hardness, better natural pest resistance, a stable domestic supply, and a lower price per pallet than imported pine. Pine requires chemical fumigation (ISPM-15) for export use; acacia does as well for export but starts with better baseline resistance.
6. What is the harvest cycle for acacia in Vietnam?Acacia auriculiformis reaches commercial harvest size in 7-10 years. This short cycle means raw material supply is consistent and prices stay relatively stable compared with slower-growing hardwood species.

Vietnam’s wood classification groups and where Acacia auriculiformis sits
In Vietnam, timber is divided into 8 groups (I to VIII) under Decision 2198-CNR of 1977. The classification is based on three main criteria: density (heavy or light wood), mechanical durability (load-bearing capacity, resistance to termites and borers) and grain value. Acacia auriculiformis (tram bong vang) is classified in Group IV.
The lower the group number (I, II), the more it consists of precious woods with beautiful grain that are very durable but rare and expensive, such as dinh, lim, sen and tau. Groups IV to VI are common-grade woods with medium density, easy to process and with a stable supply - this is precisely the most suitable range for making pallets and industrial packaging materials.
| Group | Characteristics | Typical species |
|---|---|---|
| I - II | Precious wood, beautiful grain, very durable, rare | Dinh, lim, sen, tau, gu |
| III | Durable, flexible, good load-bearing | Cho chi, sao den |
| IV | Medium density, fine grain, easy to process, stable supply | Acacia auriculiformis, hybrid acacia, mo |
| V - VI | Moderately light wood, common-grade, reasonable price | Eucalyptus, pine, rubber wood |
| VII - VIII | Light, soft wood, low load-bearing strength | Bo de, gao, vong |
Compared with other common plantation woods, Acacia auriculiformis (Group IV) ranks higher than eucalyptus and pine (Groups V-VI) in durability, and is on par with hybrid acacia wood - the two leading woods for producing wooden pallets in Vietnam.
Why the wood group does not fully determine pallet quality
The wood group only reflects the natural properties of the tree species, not the quality of the finished pallet. A Group IV acacia pallet can still be more durable than a pallet made from a higher-group wood if it is processed correctly, because final quality depends on the manufacturing process, not just on “which group” the wood belongs to.
Three factors determine a pallet’s real durability: the dryness of the wood (kiln-dried to a moisture content below 18-20% to resist warping and cracking), termite, borer and mold treatment (heat treatment or chemical impregnation), and assembly structure (number of bottom boards, type of nails, board thickness). For this reason, when choosing a pallet, the technical specifications and treatment process matter more than which group the wood belongs to.
Frequently asked questions
Which group does Acacia auriculiformis belong to in Vietnam’s wood classification?
Acacia auriculiformis (tram bong vang) belongs to Group IV in Vietnam’s 8-group wood classification under Decision 2198-CNR of 1977. This is a wood group with medium density, fine grain, easy to process and with a stable supply.
Is Group IV Acacia auriculiformis good for making pallets?
Yes. Group IV Acacia auriculiformis has good load-bearing capacity, natural termite resistance thanks to its essential oils and a reasonable price, which makes it a leading pallet material in Vietnam. Acacia wood pallets at ICD Vietnam come with a 2-year warranty. Contact the hotline at 0983 797 186 for advice.
Which is more durable, Acacia auriculiformis or hybrid acacia?
Both belong to Group IV and have comparable durability when used for pallets. Acacia auriculiformis has a higher essential-oil content, so it resists termites slightly better, while hybrid acacia provides a straight trunk with fewer knots. Final durability depends on the manufacturer’s drying and treatment process.
