In Canton Railroad Co. v. Rogan, 340 U.S. 511 (1951) a railroad company argued that the Import-Export Clause prohibited the state from taxing goods loaded on and unloaded from its trains. The Supreme Court found that it did not have to address that issue because the railroad company did not actually perform loading and unloading. However, the Court noted the following in dicta: "To export means to carry or send abroad; to import means to bring into the country. Those acts begin and end at water's edge. The broader definition which appellant tenders distorts the ordinary meaning of the terms. It would lead back to every forest, mine, and factory in the land and create a zone of tax immunity never before imagined. For if the handling of the goods at the port were part of the export process, so would hauling them to or from distant points or perhaps mining them or manufacturing them. The phase of the process would make no difference so long as the goods were in fact committed to export or had arrived as imports." (Canton, 340 U.S. at 515, 71 S. Ct. at 449.)
