Art. 182 provides for criminal penalties of imprisonment or a monetary penalty for any person who as a supplier, intermediary or customer engages in the trafficking of a human being for the purpose of sexual exploitation, exploitation of his or her labor or for the purpose of removing an organ. If the victim is a minor or if the offender acts for commercial gain, the penalty is imprisonment for not less than one year. In every case, a monetary penalty must also be imposed. The statute also provides that the soliciting of a person for these purposes is equivalent to trafficking, and that any person who commits the act abroad is also guilty of an offense.
