Bulk cargo refers to large quantities of goods that are transported without packaging. This type of cargo is typically loaded directly into a ship's hold, making it efficient for shipping materials like coal, grain, or iron ore. Bulk cargo can be categorized into two main types: dry bulk and liquid bulk. Dry bulk includes solid materials, while liquid bulk consists of liquids such as oil or chemicals. Transporting bulk cargo is essential for global trade, as it allows for the movement of raw materials and commodities needed for various industries.
