Process

Step 1: Wood Selection

We hold a distinct advantage thanks to our in-depth understanding of forest plantation regions across Vietnam. Through our extensive partner network, we have precise knowledge of wood species, quality characteristics specific to each area, optimal harvesting periods, and stable yield capacity. This allows us to consistently procure the right types of wood suited for charcoal production while maintaining a continuous and reliable supply for export markets.

Step 2: Harvesting

The timber is cut in accordance with proper specifications and undergoes strict selection to ensure that only the highest-quality logs are used for carbonization. With premium raw materials, we guarantee that the finished charcoal achieves high durability, low ash content, and consistent performance throughout use.

Step 3: Charcoal Production Network

We take pride in our extensive network of over 500 affiliated carbonization facilities spanning from the North to the South of Vietnam. This nationwide presence allows us to allocate raw wood directly to the nearest suitable kiln, optimizing both transportation costs and production time. These efficiencies form the foundation of our commitment to delivering charcoal products at the most competitive prices in the market.

Step 4: Charcoal Carbonization Process

The wood is stacked inside the kiln in tightly packed rows, filled all the way to the top to ensure proper density.

The carbonization process takes place continuously through multiple phases at temperatures ranging from 1000 to 1200°C, typically lasting 7 to 15 days, depending on the wood species and its moisture content. Operating the kiln requires extensive practical experience, as even minor deviations in timing, temperature, or oxygen levels can immediately affect the charcoal quality. Thanks to our skilled kiln operators, each firing cycle can produce up to 1 ton of finished charcoal.

Step 5: Airtight Handling

Immediately after the firing process is completed, the charcoal is removed from the kiln and transferred directly into specialized steel drums, which are sealed completely airtight. This is a critical step to prevent any exposure to air, thereby avoiding charcoal explosions caused by sudden oxidation reactions.

Step 6: Storage

The charcoal is stored in a strictly controlled environment with regulated temperature and airflow. Even minimal air exposure during this stage can cause the product to absorb moisture and ambient gases; therefore, we implement a fully enclosed storage protocol to maintain the stability and consistency of every batch.

Step 7: Packaging

Before shipment, the charcoal is cut and sieved according to the exact specifications required by the customer—from length, thickness, and diameter to overall product uniformity. Once the charcoal meets all standards, it is packed using specialized protective packaging to safeguard it from environmental impact and maintain quality throughout storage and transportation.

In addition, we offer private-label support by providing customized packaging and logo printing services to help customers build their own brand.
