United States Customs and Border Protection officers in Long Beach, California, seized nearly 750 cartons of illegally imported cigarettes from two cruise ship passengers who had arrived from Ensenada, Mexico.

The discovery was made on April 17 during an inspection of 10 pieces of luggage belonging to the couple., according to USATODAY.

The contraband included popular cigarette brands such as Newport 100s, Marlboro Red, and Marlboro Silver.

CBP announced the seizure in a news release on Wednesday.

The agency did not disclose the identities of the travelers or the name of the cruise line involved in the incident.

“Large quantities of cigarettes are considered ‘commercial’ not personal use; therefore, an importer permit from the U.S. Alcohol and Tobacco Tax and Trade Bureau (TTB) is required,” CBP said in the release. “In addition, tobacco product labels must meet FDA standards, such as including nicotine warnings and accurate product descriptions.”

The two women presented receipts for the cigarettes but lacked the necessary permits. CBP valued the cartons, which will be destroyed under agency supervision, at $59,920.

“Selling illegally imported cigarettes could yield high profits for underground vendors due to the low cost of cigarettes when purchased overseas and the evasion of taxes owed upon import,” added Africa R. Bell, CBP Port Director of Los Angeles/Long Beach Seaport. “This type of scheme not only evades revenue owed to the United States but may be harmful to the American consumer.”

The news follows a late April incident in which CBP officers seized nearly 72 grams of heroin mixed with fentanyl from a cruise passenger arriving in Galveston, Texas.
