Standard shipping containers come in 20-foot and 40-foot sizes. When you are shipping a container to Thailand, you will have two further options: a full container load (FCL) or a less-than-container load (LCL, or groupage).
Ten standard pallets is the maximum capacity of a 20-foot container; a 40-foot container will carry 22 standard pallets. If your shipping volume is equal to at least half of a 20-foot container (six pallets or more), then a full container load (FCL) will suit your needs.
You may wish to engage FCL as well even for a smaller shipment if you want to separate your goods from those of other exporters. If isolation of goods is not a concern, you could choose to share a container with other exporters in a practice known as groupage (LCL). Groupage requires you to pay only for the space you need. Consult iContainers for rates and other important information.
If you are working against a short deadline or with an urgent shipment, air freight may be worth investigating. Air freight comes with some limitations in terms of volume and weight; iContainers provides a calculator to help you determine whether this is the right option for you.
