Fumigation is a method of killing pests, termites or any other harmful living organisms to prevent transfer of exotic organisms. Fumigation is executed, by suffocating or poisoning pest, within an area of specified space by using fumigants. Normally, fumigation is done for wood material used for packing of goods to be exported. In some cases, empty container before stuffing of cargo is fumigated. Most of the cases, fumigation is done after completion of stuffing of cargo and closing the door of container. The result of such fumigation is more effective, as the gases used for fumigation circulates all spaces in the container without spreading gas outside, as the container is closed. However, this method of fumigation is not allowed for the cargo for certain food products for direct consumption and other specified goods.
Heat treat pallets are required for all wood packaging material used in international shipments. One of the necessary steps for ensuring the safety of not only the product being shipped, but also the environment of the product's destination, is heat treatment.
