The tax was nothing more than an effort of California to defray a part of the state's expenses by a uniform sales tax on all those businesses, including Richfield, which enjoyed California's natural resources, the labor of its people, and the services and protection of its government.
True, the tax would impose a burden on export commerce to the extent that it increased the export price of Richfield oil. But if a tax on export sales be unconstitutional for imposing such a burden, so is a property tax or a severance tax applied to Richfield's oil anywhere from well to consumer.

It seems clear that we cannot write any such qualifications into the Import-Export Clause. It prohibits every State from laying 'any' tax on imports or exports without the consent of Congress. Only one exception is created-'except what may be absolutely necessary for executing its inspection Laws'. The fact of a single exception suggests that no other qualification of the absolute prohibition was intended. It would entail a substantial revision of the Import-Export Clause to substitute for the prohibition against 'any' tax a prohibition against 'any discriminatory' tax.

After today's ruling Congress itself can neither tax nor permit states to tax sales like the one here proscribed. To classify sales transactions as having occurred after exportation began therefore results in creating an island of constitutional tax immunity for a substantial proportion of the profitable business of the nation. Such a result not only grants tax immunity to many profitable businesses which share governmental protections from payment of their fair part of taxes; it also throws an unfair part of the tax burden on others.
