Break Bulk

Published July 15, 2020

Break-bulk cargo refers to goods that are shipped individually — in boxes, bags, drums, crates, or on pallets — rather than packed inside standard shipping containers. The term comes from the practice of “breaking bulk” at ports, where large quantities of loose cargo are unloaded piece by piece from a vessel. Break-bulk shipping was the dominant ocean freight method before containerization and remains relevant today for cargo that is too large, heavy, or awkwardly shaped for standard containers.

Break-Bulk vs. Container Shipping

Containerized ocean freight (loaded into standard 20-foot or 40-foot ISO containers) is now the norm for most commercial goods — enabling automated handling, consistent sizing, and intermodal transfer between ships, trains, and trucks. Break-bulk remains the method of choice for: oversized machinery and industrial equipment, steel and metal products (coils, plates, beams), project cargo (wind turbine components, oil rig equipment), and forest products (lumber, paper rolls) that don’t fit economically into standard containers.

Break-Bulk and Shipping Cost

Break-bulk shipping is generally more expensive per ton than containerized freight because it requires more labor-intensive loading and unloading, specialized port equipment (heavy lift cranes), and more time in port. Shippers of oversized or heavy-lift cargo should work with specialized project cargo freight forwarders who understand break-bulk vessel networks and port handling requirements.
