Since 2001, many foreign countries have implemented strict rules and regulations related to the treatment of wood packaging material allowed into their countries in an effort to control the risk of pest infestation. Heat treatment specifications are set forth in ISPM-15 of the IPPC regulations pertaining to the use of solid wood packaging material in export applications. These regulations apply to both coniferous (softwood) and non-coniferous (hardwood) lumber.
All lumber listed in our crating grade lumber inventory is heat treated or kiln dried/heat treated to a minimum core temperature of 133 degrees Farenheit for a minimum of 30 minutes. This heat treatment exceeds the standards in ISPM-15. Heat treatment is performed at the mill where the lumber is manufactured and each piece is mill stamped HT or KD/HT as required.
Industrial lumber also operates its own certified heat treating chamber and is licensed to treat previously untreated lumber and stamp it for use in export packaging. This heat treatment chamber can also be used to treat wood crates, boxes and skids built by our customers that do not have their own official HT Stamp.
