Shipping sea containers has transformed the way we trade, move, and connect across continents. Whether you are a first-time shipper, an expanding e-commerce business, or an established freight forwarder, understanding how to ship sea containers can mean the difference between a costly mistake and a successful, streamlined delivery.
At Freight-Calculator, we pioneered the world's first instant online freight calculators, empowering shippers to get fast, transparent, and accurate rates for container shipping. Today, we will share our best knowledge on how to ship sea containers, the cost factors, and how to calculate your freight easily using modern tools.
What Is Sea Container Shipping?
"Sea container shipping" refers to the transport of goods packed inside large, standardized shipping containers that move aboard specialized container vessels. These steel boxes, typically 20-foot or 40-foot containers, revolutionized global trade by significantly reducing handling costs, minimizing cargo damage, and streamlining customs processes.
You may hear container shipping described in two main categories:
FCL (Full Container Load): the entire container is dedicated to a single shipper. See our FCL calculator for instant pricing.
LCL (Less Than Container Load): multiple shipments are consolidated in one container, sharing the space and cost. You can estimate with our LCL export calculator or LCL import calculator.
Freight-Calculator provides tools to instantly compare these options, ensuring you select the best shipping method for your cargo type and budget.
Benefits of Shipping Sea Containers
Choosing containers as your shipping method brings enormous advantages:
✅ Protection: Steel containers shield goods from weather, theft, and damage.
✅ Efficiency: Containers can be seamlessly transferred between ships, trucks, and trains (intermodal), reducing handling time.
✅ Cost savings: Standardized sizes allow straightforward pricing, scheduling, and consolidation.
✅ Global acceptance: Virtually every port, warehouse, and customs facility is built around container standards.
For these reasons, shipping sea containers remains the backbone of global freight transportation.
Container Sizes Explained
When planning your shipment, understanding the dimensions of the container is crucial.
20-foot container (Dry Van): About 1,172 cubic feet of capacity. It is ideal for heavy or dense cargo.
40-foot container (Dry Van): About 2,390 cubic feet. The industry's workhorse for general cargo.
High Cube 40-foot container: Same footprint as the standard 40-foot but one foot taller, around 2,700 cubic feet — perfect for lighter, bulkier goods.
These standardized containers allow you to calculate space and costs reliably using our container shipping rate calculator to price FCL or LCL shipments on demand.
How Much Does It Cost to Ship a Sea Container?
Container shipping costs vary depending on multiple factors:
✔️ Origin and destination ports (check pull-down U.S. Terminals Index)
✔️ Container size (20ft or 40ft)
✔️ Weight and type of cargo
✔️ Peak season surcharges
✔️ Fuel adjustments (bunker)
