1) Entry Permission, Stamps, And Stay Length
Arrivals complete immigration inspection and receive permission to stay. The classic tourist entry (FMM/record) can be granted for up to 180 days, but the officer may approve fewer. Keep your permission handy, digital or paper as issued at your port. Overstays can mean fines and delays when departing.
Tip: Your passport should be valid for the duration of your stay. For country-specific notes and security alerts, the U.S. State Department maintains a Mexico page that’s worth scanning before you fly.
2) Customs Basics: What Counts As Personal Items
Mexico’s customs agency lists what you can bring as personal baggage and what falls under your duty-free allowance (“franquicia”). Typical items include clothing, a personal laptop or camera, and medicines for personal use. If you exceed the allowance or bring restricted items, declare them on arrival and be ready to pay duties.
3) Prescription Drugs And Medical Supplies
Bring prescriptions in original containers with your name and dose. Some substances (including controlled meds) can require a COFEPRIS import permit ahead of time, especially when quantities exceed normal personal use or the drug is tightly controlled. Border agents and health officials can ask for your doctor’s letter and dosage plan.
If your itinerary hinges on a specific therapy, don’t leave this to chance—review COFEPRIS’ permit pages and carry paper copies. Airlines may also request documentation for syringes or large liquid medical feeds.
4) Vaping Devices And Liquids
Commercialization of e-cigarettes and similar devices is banned nationwide. A 2022 decree barred circulation and sales, and in January 2025 reforms were published in the official gazette to constitutionalize the ban. Travelers report inconsistent storefront availability, but possession or import for sale can trigger seizures and penalties.
5) Firearms, Ammunition, And “Forgotten” Brass
Tourists cannot import firearms. The federal firearms law puts control under SEDENA; violations can lead to arrest even for a single round found in luggage. Before you pack, clear every pocket and vehicle compartment. Hunting trips require specialized permits handled directly with Mexican authorities in advance—don’t wing it at the border.
6) Driving Rules: Seatbelts, DUI, And Child Restraints
Mexico’s national road-safety framework sets the floor for states: seatbelts on, helmets for riders, sober driving, and child restraint systems. BAC limits and checkpoints are common in major cities and resort corridors; several jurisdictions run near-zero limits. If you plan to drive across states, research local rules before you hit the road.
7) Alcohol Sales And Age
The minimum age to buy and consume alcohol is 18. Sales hours and open-container enforcement vary by city, and DUI penalties can be steep. Keep your ID handy, especially in resort towns that check wristbands and age tags at entrances.
8) Drones: Registration And No-Fly Basics
Drones fall under the aviation regulator. Weight, purpose, and location determine if you need registration or extra steps. Stay clear of airports, crowds, and archaeological zones; keep line of sight; and observe altitude caps. Review AFAC’s RPAS page before flying, and carry your proof of registration if your unit requires it. For an official primer, see the AFAC RPAS guidance.
9) Archaeological Heritage: Look, Don’t Pocket
Pre-Hispanic artifacts and many colonial-era objects are protected by federal law; they’re property of the nation. Removing, buying, or exporting them is illegal. Mexico actively recovers pieces from abroad, and border inspections do seize items. If a market stall offers “ancient” figurines, walk away.
10) Wildlife, Shells, And “Natural” Souvenirs
Mexico prosecutes wildlife trafficking. Buying protected animals or parts (feathers, shells, coral, reptile skin) can bring heavy penalties. PROFEPA has reinforced crackdowns and public guides to report illegal sales. When in doubt, skip it.
How These Rules Play Out On A Typical Trip
Airport Arrivals
Have your passport ready at immigration, then follow signage for customs. If you packed food, large electronics for resale, or unusual gear, choose the “declare” lane. If you’re carrying prescription syringes or temperature-sensitive meds, keep them together with documentation for quick inspection.
Driving Days And Road Checks
Police can run sobriety stops, and seatbelts are expected for every occupant. In federal corridors, the national mobility law backs up enforcement on basics like helmets and restraints, while city rules handle speed, parking, and local BAC thresholds. Rental contracts often ban off-road use; crossing state lines doesn’t change your responsibility to comply.
Beaches, Ruins, And Drones
At archaeological zones and dense beaches, recreational flights are often restricted or require special permits. Security staff will ask for your AFAC registration if your aircraft falls in a regulated class. Many sites also bar drones outright to protect visitors and monuments.
Paperwork, Proof, And What To Carry
Essentials Checklist
- Passport and a photo of the ID page stored offline.
- Proof of stay authorization (entry stamp/record) and return ticket if asked.
- Prescription meds in original containers; doctor’s letter for injectables or controlled substances; COFEPRIS permit if required.
- Insurance card and a copy of policy benefits.
- For driving: license, rental contract, and emergency numbers.
Two Things Travelers Trip Over
Forgotten ammo or a stray magazine in a backpack from a prior range day can ruin a vacation. Do a “white-glove” sweep of every pocket before flying.
Souvenir temptations like coral, turtle shell, or live parrots are legally risky. Stick to ceramics, textiles, coffee, and packaged food from reputable shops.
Traveler Scenarios: Clear Answers
Can You Bring A Month Of Prescriptions?
Yes, for personal use. Keep meds in pharmacy packaging and carry the prescription. For controlled substances or larger quantities, review COFEPRIS permit guidance in advance.
Is Public Vaping Allowed If You Bring A Device From Home?
Public sale and commercialization are banned nationwide, and authorities have tightened the legal framework. Retail enforcement varies, but travelers have seen confiscations during inspections. Don’t plan on buying refills locally.
Can You Fly A Drone Over Ruins At Sunrise?
No. Heritage sites commonly prohibit flights, and AFAC rules restrict operations near people and sensitive zones. Stick to permitted areas and carry proof of registration where required.

Smart Packing And Behavior Tips
Pack Light, Pack Legal
Match your electronics and photo gear to the customs list. If you’re carrying pro-grade equipment or stacks of sealed products, expect questions at customs. Keep receipts accessible for new goods still in retail boxes.
Keep Health Items Organized
Use a single pouch for meds with copies of your prescriptions. If any item needs a permit, print the authorization and save a PDF on your phone. COFEPRIS’ portal outlines how personal-use imports work—bookmark it before you go.
Be Drone-Ready
Know your aircraft weight and features. Bring spare propellers, a fire-safe battery bag, and your registration evidence if required. Keep a polite script ready in Spanish to show security staff you understand the rules. AFAC’s RPAS page is the definitive reference.
Respect Sites And Nature
Photography is welcomed at most public spaces, but physical removal of objects is not. Avoid buying items that look like bone, shell, or ancient pottery. PROFEPA has emphasized stronger penalties for trafficking—don’t risk it for a “souvenir.”

Final Reader Wins
Keep your passport and stay authorization tidy, respect customs lists, bring meds the right way, and skip anything that looks ancient or alive. If you plan to fly a drone, read the aviation page before you launch. With these ten points handled, you’ll spend your time on beaches and plazas—not at a counter sorting out paperwork. Safe travels.
