Edward Douglass White, Vance v. W. A. Vandercook Company…
“ To what purpose should the power to allow importation be given, unaccompanied with the power to authorize a sale of the thing imported? Sale is the object of importation, and is an essential ingredient of that intercourse of which importation constitutes a part. It is as essential an ingredient, as indispensable to the existence of the entire thing, then, as importation itself. It must be considered as a component part of the power to regulate commerce. Congress has a right, not only to authorize importation, but to authorize the importer to sell. ”
