Mexico Customs Prohibited items
Leave the “Garbage Pail Kids” at Home
Do you remember those ridiculous “Garbage Pail Kids” trading cards that were so popular back in the late 1980s? Well, if you are planning to visit Mexico, be sure to leave your cherished collection of crass stickers at home. Mexico actually prohibits the import of any articles that contain images portraying "childhood in a denigrating or ridiculous manner, in attitudes which incite violence, self-destruction, or any other type of anti-social behavior..."
Mexico's Strict Weapons Laws
Firearms and ammunition cannot be taken into Mexico, without first obtaining the proper permits from the Secretaría de la Defensa Nacional and also from the Secretaría de Economía.

A knife or pocketknife, carried on your person in Mexico, is also illegal, and has a prison sentence of up to five years.
Items Prohibited From Importing / Exporting

Prescription Medications Require Valid Prescriptions
Possessing prescription medications, without having the appropriate physician's prescription to go along with them, is also illegal. If you need to bring any prescription medications with you during your Mexico visit, it is best to carry them in their original containers. If you are planning to purchase any prescription medications while in Mexico, you will need a valid Mexican prescription.
Agriculture, Livestock Fish and other Food
Mexico's Ministry of Agriculture prohibits the import of a number of items because they pose a huge risk for potentially introducing disease or plague into the country. Homemade foods, meats, hay/straw, and dirt are all prohibited from being imported into Mexico.
