Buyers typically choose between three main categories: Machine-made Bamboo/Wood Charcoal (Briquettes), which offers long burning times (4-6 hours) and high heat, making it ideal for commercial BBQ restaurants; Lump Charcoal, which ignites quickly and provides a natural smoky flavor preferred for high-end grilling; and Coconut Shell Charcoal, known for being eco-friendly, smokeless, and odorless, perfect for indoor or shisha use. For B2B procurement, hexagonal briquettes are the most popular due to their high density and space-efficient packaging.
