What Is US Import by Sea Freight?
Sea freight, also known as ocean freight, is the most economical and widely used transportation method for importing goods into the US. It involves shipping cargo via container vessels from international ports to major American gateways such as Los Angeles, Long Beach, New York, and Savannah.
| Shipping Type | Description | Best For | Cost Range (per CBM) |
|---|---|---|---|
| FCL (Full Container Load) | Exclusive use of a container | Large-volume shipments | $1,200–$3,500 |

| Break Bulk | Non-containerized cargo | Machinery, oversized goods | Varies by size |
Sea freight is especially favored for heavy, bulky, or non-urgent cargo due to its balance of low cost and high capacity.
