Heat Treated Pallets

Heat treated pallets and crating material will have a "HT" stamp as in the photo below.   Cargo can be rejected at the US export terminal or the foreign import terminal if the pallet or crating materials are not heat treated.  Plastic, cardboard or manufactured packing materials do not need to reflect a heat treating stamp.  The purpose of the heat treating requirement is to reduce the risk of transporting wood boring insects.
