In a final rule published in the Federal Register on September 16, 2004, the U.S. Department of Agriculture (USDA) amended its regulations with the goal of decreasing the risk of introducing plant pests into the United States. USDA has adopted the international standard for wood packaging material (WPM) that was approved by the International Plant Protection Convention (IPPC) on March 15, 2002.
The IPPC standard calls for most WPM to be either heat treated or fumigated with methyl bromide in accordance with the Guidelines and marked with an approved international mark certifying that treatment. The final rule, became effective on September 16, 2005, affects all persons using wood packaging material in connection with importing goods into the United States.
