ISPM 15 affects all wood packaging material (pallets, crates, dunnages, etc.) and requires that they be debarked and then heat treated or fumigated with methyl bromide, and stamped or branded [1] with a mark of compliance. This mark of compliance is colloquially known as the "wheat stamp".
Wood treated with this process is often used for cladding or siding, flooring, furniture and windows. For the control of pests that may be harbored in wood packaging material (i.e. crates and pallets), the ISPM 15 requires heat treatment of wood to 56 °C for 30 minutes to receive the HT stamp.
Heat treatment: The wood must be heated to achieve a minimum core temperature of 56 °C (133 °F) for at least 30 minutes. Pallets treated using this method bear the initials HT near the IPPC logo.
