United States government regulations require that lumber used in packaging materials (crates, pallets, etc.) that are exported complies with the standards contained within ISPM 15 (International Standards for Phytosanitary Measures). This standard ensures that certain pests such as the Asian long horned beetle and others have been eradicated from the lumber. Heat treatment of lumber is an approved means of eradication. To provide proof of heat treatment, each piece of heat treated lumber within a pallet or crate must have an "HT" stamp. Here is an example:
Plywood, oriented strand board, and laminated veneer lumber (LVL) are members of the engineered wood family. Engineered wood is different from solid wood in that it is manufactured by bonding together wood strands, veneers, lumber, or other forms of wood fiber. Becasuse the process of manufacturing engineered wood destroys any live organisms in the wood, engineered wood packaging materials are exempt from ISPM 15.
