(shipping container) A cylindrical container used for shipping dry or liquid bulk cargo. Shipping drums can be made of steel, dense paperboard (commonly called a fiber drum), or plastic. Also called a barrel. Drums are most typically used for shipping liquid chemicals.
Dums made of plastics–usually thermoplastics like polyethylene, nylon, polystyrene, polyvinyl chlorides (PVCs), or possibly polycarbonates–are the preferred shipping container for the shipment of caustic and acid materials.
Drums made of steel are the preferred shipping container for flammable substances like most petroleum distillates and alcohol.
