Dear Deputy Assistant Secretary Longnecker: The U.S. Chamber strongly opposes the establishment of tariffs or quantitative restrictions on imports of timber, lumber, and their derivative products such as paper, cardboard, and pulp. Imports of these goods do not represent a national security risk, as addressed below. Imposing tariffs on these goods would raise costs for U.S. businesses and home construction, undermine the export success enjoyed by the U.S. paper industry, and reduce incomes in many U.S. communities… It is unreasonable to suggest that imports of these goods represent a national security risk, in part because the chief source of imports in this sector is Canada, a NATO ally and North American Aerospace Defense Command (NORAD) partner… It is not reasonable to claim that imports of these goods from a close ally somehow pose a threat to U.S. national security.
