Shipping containers are essential for transporting goods across oceans, land, and rail. Among the most commonly used are the 20-foot and 40-foot containers. Whether you’re importing machinery, consumer goods, or raw materials, understanding the weight, capacity, and internal dimensions of these containers is crucial for logistics planning and avoiding penalties.

20ft vs 40ft Shipping Containers: Quick Comparison

Feature20ft Standard Container40ft Standard Container
Tare Weight (Empty)~2,300 kg (5,071 lbs)~3,750 kg (8,268 lbs)
Max Gross Weight30,480 kg (67,200 lbs)30,480 kg (67,200 lbs)
Max Payload~28,180 kg (62,128 lbs)~26,730 kg (58,932 lbs)
Interior Volume~33.2 m³ (1,170 ft³)~67.6 m³ (2,385 ft³)
Pallet Capacity10 standard pallets (single stack)20–22 standard pallets (single stack)

Key Takeaway: A 40ft container offers double the volume of a 20ft but not double the weight capacity, which is why shippers choose based on the nature (bulk vs weight) of their cargo.

How to Ship a 20ft or 40ft Container

Shipping full-size containers, whether 20ft or 40ft, involves several coordinated steps. Here’s a simplified overview of the process, as explained by Freightos:

1. Choose Full Container Load (FCL) or Less than Container Load (LCL)

  • FCL (Full Container Load): You rent the entire container. Best for large shipments or when you want exclusive use.
  • LCL (Less than Container Load): You share space in a container with other importers. Best for small loads but takes longer due to consolidation.

2. Get a Freight Quote

Use online freight marketplaces like Freightos or contact a freight forwarder to get shipping costs based on:

  • Container size (20ft or 40ft)
  • Port-to-port or door-to-door service
  • Cargo type, weight, and volume
  • Destination country and import duties

3. Book the Shipment

  • Choose your incoterms (EXW, FOB, CIF, etc.)
  • Confirm pickup date, loading location, and transit time.
  • Provide documents: commercial invoice, packing list, and shipping instructions.

4. Pack and Load the Container

  • Ensure cargo is packed securely with proper bracing.
  • Use pallets to ease loading and unloading.
  • For 20ft containers, weight density matters (ideal for heavy cargo).
  • For 40ft containers, consider volume efficiency (ideal for bulky goods).

5. Container Pick-Up & Port Delivery

  • The container is trucked to your warehouse or factory.
  • After loading, it’s sealed and transported to the port.

6. Customs Clearance & Ocean Freight

  • Submit customs documentation.
  • Pay duties, taxes, and any applicable fees.
  • Container is loaded on a vessel and shipped to the destination port.

7. Arrival & Final Delivery

  • On arrival, the container clears customs.
  • It’s then delivered to the consignee’s warehouse or facility via truck or rail.

Why Container Weight Matters

Freight charges are based on weight or volume, depending on which is higher. Overloading a container can lead to penalties or cargo rejection.

Trucks and railcars must stay within legal axle load limits. Overweight containers may need special permits or handling.

Proper load distribution prevents cargo damage, shifting during transit, and accidents during lifting and unloading.

How Many Pallets Fit?

Pallet Type20ft Container40ft Container
Standard Pallet (1.2m x 1m)~10~20–22
Euro Pallet (1.2m x 0.8m)~11~25

Note: Figures depend on pallet configuration and loading method.

Final Thoughts

Both 20ft and 40ft shipping containers are critical to international trade. A 20ft container is more suitable for dense, heavy cargo, while a 40ft container offers more volume for bulkier goods. Knowing their weights, dimensions, and how to ship them ensures smooth logistics operations and cost control.

FAQ:

Q1: Can a 20ft container carry more weight than a 40ft?

Yes. Due to its smaller size, a 20ft container has a higher weight-to-space ratio, making it ideal for heavy goods.

FCL is usually cheaper per unit when your shipment fills most of the container. LCL is cost-effective for small shipments.

Transit time varies by route:

  • China to US (West Coast): 12–20 days
  • China to Europe: 30–40 days
