Arriving in Thailand, each adult may bring in duty-free no more than 200 cigarettes (or 250 grams of tobacco) and 1 liter of alcohol, and must declare cash above USD 15,000 in foreign banknotes or 450,000 baht (as of October 2026). Vapes and e-cigarettes are banned outright, for tourists too.
Most visitors walk through the green "Nothing to Declare" channel without being stopped, and for most of them that is correct. The problems start with three things people do not expect to matter: a second carton of cigarettes bought at the departure airport, a vape in a jacket pocket, and an envelope of cash for a property deposit or a long stay.
This page sets out what Thai Customs and the Bank of Thailand actually allow, what is banned, and what happens at the airport if you get it wrong. The rules were checked against official sources on 1 October 2026. Prescription medicines have their own rules, which we explain in a separate guide and only summarize here.
Customs is the last step of arrival. Before it you pass immigration, which checks the free Thailand Digital Arrival Card you filed online. The channels look the same at every international airport, from Suvarnabhumi to Phuket; our overview of Thailand's airports explains which one suits your trip.

Cigarettes and alcohol: the limit is per person, and it is enforced
Thai Customs allows each arriving passenger 200 cigarettes, or 250 grams of tobacco, or 250 grams of all types combined, plus 1 liter of alcoholic drink, free of duty. That is one standard carton of cigarettes, and one bottle of spirits or wine at most. Two 70 cl bottles of whisky are already over the limit.
Many travelers assume they can bring more and simply pay duty on the extra. The Customs Department's passenger guidelines say otherwise: anything above the allowance must be dropped in the box provided by Customs, "otherwise prosecution will be carried out". The UK Foreign Office puts it more bluntly. It says the cigarette limit is enforced at customs on arrival, and that going over it can mean a fine of up to 10 times the value, with the cigarettes likely to be confiscated.
Nothing about these numbers is new. What has changed is enforcement and publicity, so older forum advice that "nobody checks" is a poor guide. Couples cannot pool their allowance either: two people with three cartons between them are over the limit, because one of them is carrying two.
Two duty-free cartons in one bag is already an offense in Thailand. Departure-airport shops in Singapore, Kuala Lumpur, Hong Kong and Europe will sell you as many cartons as you like. Thai Customs counts what you carry, per person, and the fine is up to ten times the value.
Once you are in the country, buying alcohol is governed by separate rules on sales hours and holy days. Our guide to when you can buy alcohol in Thailand covers those.
Vapes and e-cigarettes: banned, with no tourist exception
Thailand banned e-cigarettes in 2014, and the ban covers foreigners exactly as it covers Thais. The Royal Thai Embassy in London tells travelers not to bring the devices or the liquid. The UK Foreign Office (updated 28 September 2026) says it is illegal to possess or use any vape, e-cigarette, pod, e-liquid or heat-not-burn device in Thailand, and that "there are no exceptions for tourists or for personal use".
The consequences it lists are confiscation, fines typically between 5,000 and 30,000 baht, detention and court proceedings. You may also have to stay in Thailand until the case is finished, which can mean missing your flight home and paying for a hotel while you wait. Heat-not-burn devices, the kind that heat tobacco sticks rather than burning them, are named in the ban, so do not assume they count as ordinary tobacco.
It is common to see vapes on sale in tourist areas. That does not make them legal; it means sellers are breaking the law, and Thai police have run repeated crackdowns on the trade during 2025 and 2026. The safe decision is simple: leave the vape at home, finish or discard it before you fly, and do not buy one in Thailand.
Transit passengers should think about the vape question before they leave home. If you are flying on from Bangkok to a third country and will pass Thai immigration, for example to change airports, you are entering Thailand with whatever is in your bag. Plan as if the ban applies to you.
Cash: declare above USD 15,000, not 20,000
You can bring any amount of foreign currency or Thai baht into Thailand. What the law requires is a declaration to Customs when you carry more than a threshold. According to the Bank of Thailand's exchange control rules, you must declare:
- Foreign banknotes worth more than USD 15,000 in total (or the equivalent in other currencies), on arrival or departure
- Thai baht banknotes of more than 450,000 baht, on arrival or departure
Many websites still say USD 20,000. That figure relates to banks' foreign-exchange paperwork, not to cash at the border. For travelers the number to remember is 15,000. Declaring is not a tax and costs nothing; the risk lies in not declaring. Go to the red channel and tell the officer before you leave the customs hall.
Taking baht out of Thailand has its own limits. The Bank of Thailand allows up to 2 million baht to countries that border Thailand, Vietnam and China's Yunnan province, but only 50,000 baht to other countries. Travelers heading for Singapore, Hong Kong or mainland China outside Yunnan should change surplus baht before they fly. Our guide to exchanging money in Thailand covers where to do that.
Remember also that immigration, not Customs, may ask whether you can support yourself: 10,000 baht per person or 20,000 baht per family for visa-exempt visitors. That rule is explained on our page about the Thai visa exemption.
Medicines: 30 days is normal, controlled drugs need a permit
Ordinary prescription medicines can come with you in a personal quantity of up to 30 days' use, in their original labeled packaging, with a prescription or doctor's letter. Medicines that count as narcotics or certain psychotropics are a different matter. Since 21 September 2024 you can bring up to a 90-day supply of some of them, but only with a permit from the Thai Food and Drug Administration, applied for online at least 15 days before you travel.
Our full guide on taking prescription medicine into Thailand explains the categories and the documents. If you run out while traveling, the article on what Thai pharmacies sell over the counter is the next place to look.
Other things you cannot bring, or need a permit for
Thai Customs keeps a list of restricted and prohibited items. Prohibited means you cannot bring it at all; restricted means you need a permit from another government agency first.
| Item | Status | Who decides |
|---|---|---|
| Narcotics, pornography, counterfeit goods, fake banknotes | Prohibited | Customs |
| Wildlife and wildlife products covered by CITES | Prohibited without CITES papers | Customs and wildlife authorities |
| E-cigarettes, vapes, e-liquid, heat-not-burn devices | Banned | Commerce Ministry ban; Customs and police enforce |
| Food, supplements, cosmetics and medicines beyond personal use | Restricted | Thai FDA |
| Plants and animals, including pets | Restricted | Agriculture and livestock departments |
| Buddha images and antiques | Restricted | Fine Arts Department |
| Radio and telecom transmitters | Restricted | NBTC |
Two more rules surprise people. The UK Foreign Office warns that under Thailand's Playing Cards Act it is illegal to carry more than 120 playing cards, which matters for anyone traveling with several decks. Drones are legal to bring but must be registered with the National Broadcasting and Telecommunications Commission (NBTC) within 30 days of entering the country, even if you never fly them; FCDO gives the penalty for an unregistered drone as up to 100,000 baht, five years in prison, or both.
Personal belongings and the 20,000-baht line
Your clothes, camera, laptop and phone are not an issue. Customs lets through personal belongings in a reasonable quantity worth up to 20,000 baht in total duty-free in the green channel, as long as they are not food and not on the restricted list. The test is whether the goods are for your own use rather than for sale.
If you carry new goods above that value, such as an expensive watch bought abroad or gifts for family, use the red channel. According to Customs, non-commercial goods up to 200,000 baht in value are assessed at a flat rate of duty and tax on the spot, payable in cash or by card. Above that, a formal import declaration is needed. Bringing in five identical phones or a suitcase of cosmetics looks commercial, whatever the value.
Leaving Thailand: what Customs checks on the way out
Departure has its own pitfalls. Cannabis is the biggest. It is not legal to take it out of Thailand, and from 17 June 2026 Customs calculates fines for export attempts at 30,000 baht per kilogram, with the cannabis forfeited and possible prison on top. It is also illegal in most countries you might fly to. Our guide to Thailand's cannabis rules explains what is allowed inside the country.
Shoppers who want their VAT back must show the goods to Customs at the airport before check-in; see our guide to the VAT refund for tourists. Gold jewelry bought in Thailand is a popular purchase, and our article on buying gold in Thailand explains how prices work. Check your home country's import allowances too, since the strict side is often at the other end.
Frequently asked questions
How many cigarettes can I bring into Thailand?
No more than 200 cigarettes (one carton), or 250 grams of tobacco, per person. Excess must be dropped in the Customs box on arrival, and the UK Foreign Office warns that travelers over the limit can be fined up to ten times the value.
Can I bring a vape to Thailand if it is for personal use?
No. Possessing or using a vape, e-cigarette, pod, e-liquid or heat-not-burn device is illegal in Thailand, and the UK Foreign Office stresses there are no exceptions for tourists or personal use. Penalties include confiscation, fines and detention.
How much cash can I bring into Thailand without declaring it?
Up to USD 15,000 in foreign banknotes, or 450,000 baht in Thai banknotes. Above either amount you must declare the cash to Customs on arrival. There is no upper limit on what you may bring; the rule is only about declaring it.
How much alcohol can I bring into Thailand duty-free?
One liter per person in total. That is a single standard bottle of spirits or wine plus nothing else. Customs says alcohol above the limit must be left in the box provided, otherwise prosecution follows, so do not plan on paying duty on a second bottle.
Do I need to declare a laptop or camera?
Not if it is your own and in normal use. Personal belongings worth up to 20,000 baht in total go through the green channel, and Customs treats used personal electronics as belongings. New, high-value or multiple items should go through the red channel.
