Over dimensional cargo (ODC) refers to goods or cargo that exceed the standard size and weight limits set for transportation modes like trucks, trains, or ships
. It usually includes oversized, bulky, or heavy goods that cannot fit into standard shipping containers or vehicles such as large machinery, construction equipment, industrial components, or other irregularly shaped goods. Transporting ODC requires specialized equipment like flatbed trailers, specialized cranes, or heavy-lift vessels, to accommodate the unique dimensions and weight of the cargo. Special permits, route planning, and coordination with authorities may also be necessary to ensure safe and efficient transportation.
