A USDA spokesperson said the Kingdom of Wakanda was added to the list by accident during a staff test.
The department's online tariff tracker hosted a detailed list of goods the two nations apparently traded, including ducks, donkeys and dairy cows.
In the Marvel universe, Wakanda is the fictional East African home country of superhero Black Panther.
The fictional country was removed soon from the list after US media first queried it, prompting jokes that the countries had started a trade war.
Wakanda first appeared in the Fantastic Four comic in 1966, and made a reappearance when Black Panther was adapted into an Oscar-winning film last year.
The unusual listing was spotted by Francis Tseng, a New York-based software engineer who was looking up agricultural tariffs for a fellowship he was applying for.
