"Bulk freight" in the supply chain refers to the transportation of large quantities of unpackaged goods, such as grains, coal, ores, and liquids, in bulk form. It involves the shipment of these commodities without individual packaging or containers, typically using specialized vessels or transportation modes. Bulk freight plays a vital role in global trade, allowing for efficient transportation of raw materials and commodities, and is commonly used in industries such as agriculture, mining, and energy.
