Our Production Process
From carefully selected raw materials to international delivery, every stage of our production process is managed under strict quality control standards. This standardized workflow ensures consistent charcoal quality, reliable supply, and dependable service for customers worldwide.
- Step 1: Premium sawdust is collected from trusted woodworking factories, screened to remove impurities, and dried to below 15% moisture for optimal production.
- Step 2: The dried sawdust is compressed under high pressure into uniform briquettes with consistent density and shape.
- Step 3: The briquettes are carbonized in oxygen-limited kilns for 7–15 days, producing high-quality charcoal with stable performance.
- Step 4: Finished charcoal is stored in a controlled environment to prevent moisture absorption and preserve consistent product quality.
- Step 5: Only charcoal meeting strict quality standards is carefully packaged. We also provide private-label packaging and custom logo printing for OEM customers.
- Step 6: Orders are shipped through Vietnam’s major seaports with flexible logistics solutions, competitive freight rates, and reliable worldwide delivery.
- Step 7: We provide order tracking, logistics assistance, market updates, and responsive customer service, backed by a transparent return and quality guarantee policy.
