## Abstract

We are amending the export certification regulations to provide for the establishment of a program under which softwood (coniferous) packing materials used with goods exported from the United States may be certified as having been heat treated. This program is necessary because the Government of the People's Republic of China has established a requirement that coniferous packing materials exported to China must be accompanied by such certification. This change will affect persons who use coniferous packing materials to export goods from the United States to the People's Republic of China.
