Introduction to the Classification of Oversized Shipping in the United States

Heavy cargo sea freight refers to the transportation of goods that are large in volume, heavy in weight, or irregular in shape. Oversized cargo is transported by sea in the United States, which is a general term for goods that are significantly larger in volume and weight than general standard sea freight.  

1. In terms of volume, it includes three super large items: ultra-high, ultra wide, and ultra long, as well as ordinary large volume items with irregular volume.

2. In terms of weight, it mainly refers to overweight goods shipped by sea.  

3. Large scale sea transportation is mainly reflected in large machinery and equipment, engineering equipment, drilling platforms, yachts, bridge modules, locomotives, container cranes, etc.  

4. Heavy cargo shipping is a sensory perception of the volume and weight of goods by practitioners. Heavy cargo shipping is a relative concept, and for maritime practitioners, it is generally measured by the weight and volume of relative logistics.

5. The term 'large cargo shipping' does not specify the exact weight and volume of the logistics entity for large cargo, which is a common industry term.
