Daniel Marx makes an important clarification in another post: unauthorized importation appears to be only a *civil* violation, with no possibility of criminal penalties, in the US -

§ 602. Infringing importation of copies or phonorecords
(a) Importation into the United States, without the authority of the owner of copyright under this title, of copies or phonorecords of a work that have been acquired outside the United States is an infringement of the exclusive right to distribute copies or phonorecords under section 106, actionable under section 501.
Since § 501 applies only civil penalties - i.e. gives copyright holders various rights to sue - it doesn't appear that importation is 'illegal' in sense that one can be arrested and jailed. But the vague language of § 506 makes it difficult for me to be certain, and so I'll just admit that surfing through the law isn't a substitute for asking a real lawyer -

§ 506. Criminal offenses5
(a) Criminal Infringement. — Any person who infringes a copyright willfully either —
(1) for purposes of commercial advantage or private financial gain, or
(2) by the reproduction or distribution, including by electronic means, during any 180-day period, of 1 or more copies or phonorecords of 1 or more copyrighted works, which have a total retail value of more than $1,000,
shall be punished as provided under section 2319 of title 18, United States Code. For purposes of this subsection, evidence of reproduction or distribution of a copyrighted work, by itself, shall not be sufficient to establish willful infringement.
