Depends on the jurisdiction. The site is based in Canada (at least according to the TLD), which doesn't classify it as a controlled substance. The U.S., however, does classify it as such and therefore disallows importation unless you have a prescription.
Interestingly, adrafinil is completely unregulated in the U.S. (IIRC), and is sufficiently-closely related to modafinil that it basically has the same effects.
