Everything you need to know about container shipping

Container shipping has been around for over 50 years, and it’s standardisation started shortly after, led by the International Organization for Standardization (ISO).Standardised containers have transformed the shipping and transport industry, allowing the transport of goods by rail, road and ship easily, as the containers can fit onto different forms of transport with ease. The standardisation of containers has helped increase efficiency and economies of scale when transporting the approx. $3tn of trade which goes through our transport systems each year, from aerosol cans to zebras! 

There are several different standardised container sizes, but we’ve put the main three sizes here:
  • 20’GP = 20’DV = 20FT = 20′ = 20 feet general purpose
  • 40’GP = 40’DV = 40FT = 40′ = 40 feet general purpose
  • 40’HC = 40’HQ = 40 feet high cube
By keeping sizes to a particular standard, they can be used across numerous means of transport: rail, ship and road.

Types of Shipping Containers:

  1. Dry storage containers – these are the standard previously mentioned shipping containers, which are used to ship dry materials, normally in 10ft, 20ft and 40ft lengths.
  2. Flat rack containers – these contain collapsible sides which fold, ideal for shipping boats, equipments and cars.
  3. Open side containers – here the doors to the containers can be opened completely on the side, which allows for wider loading of materials, ideal for shipping vegetables.
  4. Open top containers – as per the title, these containers have no roof, which enables goods of any height to be shipped, such as logs or machinery
  5. Refrigerated containers – for food stock or pharmaceutical goods
  6. Tanks – these are designed to retain liquids (including fuels)

How freight is shipped in containers?

There are two types of container packing, Full Container Load (FCL) and Less-than-container Load (LCL), or break bulk shipments.
For those looking to import a small quantity of goods that might not require a full container’s worth of stock, it might be worth considering a Less-than-container load shipment, where a shipping broker or freight forwarder combines your supplier’s goods with others in order to make a full shipment. The unit cost per kg is more than that of a full container load, but the total delivery cost will be less. We’ve put together a comparison of FCL and LCL shipments here.
The packaging used inside containers to transport in and out of containers either consists of pallets (or skids), which are often wooden or plastic supports for the load, often shrink wrapped, slip sheets made of plastic, or crates.

Pricing :

Pricing is one of the most important factors of shipping goods, but it’s important to clearly understand the responsibility of the consignee (shipper/ buyer) and the distributor or seller.
The shipment of goods and responsibilities are clearly defined by incoterms – and there are about 13 different ones .
The two most important forms of documentation for shipping are the Bill of Lading , and the Freight Bill .In short, the buyer can arrange for their own freight agent and delivery, or deliver using the sellers freight forwarder .Generally speaking, suppliers will give a quote for an ExWorks or Free on Board transport service when delivering goods.
