Which US law pertains directly to mail fraud in the context of gray goods?

The law that pertains directly to mail fraud, particularly in the context of gray goods, is 18 US Code 1341. This statute specifically criminalizes the use of the postal service or any interstate or foreign mail system to execute or further a scheme to defraud. Gray goods often involve counterfeit or trademark-infringing items that are sold without the authorization of the brand owner, making mail fraud applicable when these goods are distributed via mail.

In addressing the other options, 15 US Code 1125 focuses on trademark infringement and false advertising, which does not specifically address mail fraud. 28 US Code 1331 deals with federal question jurisdiction, outlining the jurisdiction of federal courts over certain types of cases, but it does not pertain to specific criminal acts like mail fraud. Lastly, 18 US Code 2314 addresses the transportation of stolen goods, but it does not directly encapsulate the elements of mail fraud relevant to gray goods. Thus, 18 US Code 1341 is the most suitable choice for encompassing the criminal activities associated with mail fraud regarding gray goods.
