The whole affair has been embarrassing for the Americans, who have had to ask the Cubans if they could have their highly sensitive missile back, says the BBC's Will Grant in Havana.
The missile arrived on a flight from Paris "by mistake or mishandling in the country of origin," said a Cuban Foreign Ministry statement.
"Cuba acted with seriousness and transparency and co-operated to find a satisfactory solution to this issue," it added.
The AGM 114 Hellfire is a laser-guided missile that can be deployed from an attack helicopter or an unmanned drone.
US officials were worried that Cuba could share the advanced technology inside the missile with countries such as North Korea, China or Russia, sources close to the investigation told the Wall Street Journal.
