Physical Characteristics
Texture
Smooth, glossy exterior indicating high-pressure extrusion and low moisture intake during storage.
Durability
Mechanical durability ≥ 98%, designed for bulk transport and automated feeding systems without degradation.
7-Step Rigorous Quality Control Process
Incoming Raw Material Inspection
Checking wood moisture content, size, species and cleanliness upon arrival.
Hammer Mill & Wet/Dry Chips Check
Inspecting milled chips and sawdust (wet and dry status) for consistency.
Periodic Sampling
Taking automatic and manual samples at regular production intervals.
Pre-pellet Check
Verifying moisture and temperature of sawdust right before entering pellet mills.
Finished Pellet Check
Evaluating pellet diameter, length, density and durability after counter-flow cooling.
Third-party Lab Analysis (COA)
Sending samples to international testing bodies (SGS/VinaControl) for certificates.
Pre-shipment/Container Inspection
Final checking of moisture, dust content, container sealing and cargo security.
Technical Compliance
Verified quality standards for global export.
VinaControl Verified
Local inspection certification ensuring compliance with Vietnam's export regulations.
Actual Measured Results of Wood Pellets
Our products exceed standard parameters for industrial and residential use, ensuring maximum heat output and minimum maintenance.
kcal/kg
High energy density specifically optimized for furnace efficiency and reduced fuel consumption.
Na+K Content
Extremely low sodium and potassium content prevents furnace surface corrosion and extends equipment lifespan.
Ash Content
Ultra-low ash content (≤ 1.5%) minimizes slagging and optimizes the operational efficiency of combustion systems.
