Business Customs

Business relationships in Thailand are not as formal as those found in Japan, China, Korea, or the Middle East, but neither are they as relaxed and impersonal as is common in the United States. Many business relationships have their foundations in personal contacts developed within the social circles of family, friends, classmates, and office colleagues. Although Thailand is a relatively open and friendly society, it is advisable to approach potential business contacts with an introduction or letter from a known government official or business contact. The Commercial Service at the U.S. Embassy in Bangkok offers business matchmaking (Gold Key Service) services to help U.S. companies gain access to qualified potential partners in the Thai business community.

The Thai cultural values of patience, respect for status (such as age and authority), and not losing face are significant factors in business relationships as well. Thais feel great pride in their country and have deep respect for tradition. However, observance of traditional formalities may seem inconsistent with the tolerant, relaxed nature of living in Thailand. This can be confusing or frustrating to Westerners who are more informal and more time conscious.

Respect for and consideration of one’s elders, superiors, and patrons are deeply rooted in Thai culture and society. Thais are very reluctant to hurt the feelings of others or to openly cause them discomfort. As a result, Thais may not directly express negative answers or reactions. Losing one’s composure is losing face and losing others’ respect in Thailand. 

Respect for hierarchy is essential, so it is important to address the most senior person first and be aware of their status. Communication tends to be indirect to avoid confrontation, so paying attention to non-verbal cues and reading between the lines is important. Maintaining a polite and calm demeanor is key, as raising your voice or showing frustration is considered inappropriate. In Transparency International’s Corruption Perception Index (2024), Thailand ranks 107 out of 180 countries.

Etiquette

“Khun” is the Thai form of address for Mr., Mrs., and Ms. and is followed by a first name or nickname. However, government officials and doctors should be addressed by their title, such as Secretary, Minister, or Doctor, followed by the individual’s first name. Nicknames are common in Thailand. The “wai” is a traditional gesture of greeting and respect in Thailand made by placing your palms together in a prayer-like position at chest level and giving a slight bow. The wai is used as a greeting and as leave-taking. Thais may also be familiar with the western-style handshake.

Business cards are an indispensable part of networking with contacts in Thailand and are exchanged at every meeting. It is considered impolite to write on someone’s business card in their presence, so avoid writing notes on cards handed to you during a meeting or event.

The head is sacred and the cleanest part of the body, so Thais consider it rude to touch someone on the head. Likewise, feet are the dirtiest part of the body, and it is considered rude to point to anything with your feet. Consistent with this, shoes should always be removed before entering a home or temple. Do not cross your legs in the presence of the elderly or monks.

Thais hold the Royal Family in high esteem, and disparaging or critical comments may lead to serious repercussions, including jail time, under Thailand’s lèse-majesté law. Visitors to Thailand are expected to comport with the lèse-majesté law and not criticize the Royal Family. 

Travel Advisory

To access the most up-to-date travel and safety information please refer to the State Department’s Country Specific Information for Thailand. You can also report emergencies involving U.S. citizens by calling 1-888-407-4747 toll-free within the U.S. and Canada, or by calling a regular toll line, 1-202-501-444, from other countries.

U.S. citizens are encouraged to enroll online in step.state.gov to receive travel alerts and security information from the U.S. Embassy in Bangkok or the U.S. Consulate General in Chiang Mai.

Access to Thai government services, such as application for work and retirement visas, permission to buy and sell property, permission to marry, and obtaining a driver’s license, entails navigating an extensive, paper-reliant bureaucracy. Be advised that the U.S. Embassy and Consulate General CANNOT notarize documents that appear to “authenticate” state or locally issued U.S. official documents (e.g., birth/marriage/death certificates and academic degrees) nor can the Embassy and Consulate General “verify” income or domicile in Thailand. For information on what the Embassy/Consulate General can and can’t notarize, and how to properly authenticate U.S.-sourced documents, please visit the U.S. mission to Thailand’s webpage.

Visa Requirements

U.S. Companies that require foreign businesspersons to travel to the United States are advised that security evaluations are handled through an interagency process.  Visa applicants should go to the following link(s): State Department Visa Website. 

For the most up-to-date information on Thailand’s entry requirements, please consult the Tourism Authority of Thailand’s website. The U.S. Embassy and Consulate General are unable to intervene with Thai Immigration or airlines regarding their regulations and policies. Travelers must pay a Passenger Service Charge in Thai baht when departing from any of Thailand’s international airports; this charge is included in the ticket price for flights from Bangkok’s main airport, Suvarnabhumi International.

When a traveler enters the country, Thai Immigration stamps his or her passport with the date on which the traveler’s authorized stay in Thailand will expire. Any traveler remaining in Thailand beyond this date without having received an official extension will be assessed an immediate cash fine when departing Thailand. Any foreigner found by police to be out of legal status prior to departure (during a Thai Immigration “sweep” through a guesthouse, for example) will be jailed, fined, and then deported at his or her own expense, and may be barred from re-entering Thailand.

Travelers to Thailand MUST arrive with at least six months’ validity remaining on their passports, or they will be denied entry. In addition, travelers may be refused entry if their passports do not have two or more blank pages remaining; be advised that Thai immigration authorities may not consider the “endorsement” pages found in some older U.S. passports usable for immigration stamping. Travelers are also instructed to fill out a Thailand Digital Arrival Card online three days prior to entry here: Thailand Digital Arrival Card.

U.S. citizens should be aware that private “visa extension services,” even those advertising in major periodicals or located close to Immigration offices or police stations, are illegal. Unofficial or illegal visas obtained through illegal service providers can lead to an arrest at the border. 

Currency

Upon arrival in Thailand, money exchange centers are available after clearing the customs checkpoint. The money exchanges are generally located immediately outside of baggage claim/customs at international airports.  There are ATMs for direct withdrawals and cash advances. Credit cards are widely used in major tourist locations, but small bills should be carried for incidentals and taxis. In recent years, digital payment options have increased in popularity. Consumers report using multiple digital payment platforms, including QR codes and mobile wallet payments. 

Telecommunications/Electronics

In urban areas like Bangkok, Thailand’s telecommunication services meet international standards. Thailand was the first country in ASEAN to launch 5G services. The Bangkok metro area is served by two fixed-line operators: The National Telecom Agency, a state enterprise, and True Corporation PLC, a private company. At the time of writing, local calls from fixed-line numbers to fixed-line numbers are not timed and carry a fixed charge of three baht per call.

Areas outside of Bangkok are served by the National Telecom Agency and a private company, TT&T Public Co., Ltd, with a total fixed-line capacity of over 8 million lines.

As of early 2025, Thailand has 91.81 million mobile subscribers (130 percent penetration rate) and 63.21 million internet users (88 percent penetration rate). 

Transportation

Air Travel
Thai Airways International is the flag carrier of Thailand serving both domestic and international routes. Thailand currently has 39 commercial airports, 10 of which are international airports. Thailand’s two busiest airports are Suvarnabhumi International Airport (BKK) and Don Mueang International Airport (DMK), both located in Bangkok. The other eight international airports (in order of passenger traffic) are located in Phuket, Chiang Mai, Hat Yai, Krabi, Ko Samui, Chiang Rai, Udon Thani, and U-Tapao. Suvarnabhumi International Airport is located 18 miles (30 kilometers) east of downtown Bangkok. 

The Public Transportation Center at Suvarnabhumi Airport offers public bus service to popular destinations in Bangkok. Airport limousines and public taxis are available at the airport with a small surcharge. Transport from the airport to the inner city can take 40 to 60 minutes or more, depending on traffic conditions. More information is available on the Suvarnabhumi Airport website.

Taxis and Ride-Hailing
Thailand offers a range of ground transportation in Bangkok and major cities. Metered taxis are common, and most hotels offer limousine services. Chauffeured cars can be rented for extended stays. In Bangkok, an extensive public bus network with both air-conditioned and non-air-conditioned vehicles serves all areas of the city. Ride-hailing services like Lineman, Estonia’s Bolt, and Grab are available and legal under a regulation that allows the use of personal cars for ride-hailing taxi services. 

Rail 
Bangkok has ten rapid transit rail lines, including Bangkok Transit System (BTS), Metropolitan Rapid Transit (MRT), commuter rail lines (Light Red Line and Dark Red Line), and the Airport Rail Link, which connects to Suvarnabhumi Airport. The BTS, known locally as Sky Train, is an elevated train network that operates three lines in Bangkok’s most congested business districts, including the Sukhumvit Line, Silom Line, and Gold Line. The MRT is a subway system that includes a Blue Line, and Purple Line, while the monorail train line system are Yellow Line and Pink Line. 

Bangkok’s new main train terminal, Krung Thep Apiwat Central Terminal, opened in 2023, with 52 long-distance Rapid, Express, and Special Express services. A limited number of ordinary trains still depart from Hua Lamphong Railway Station, the former central passenger terminal of Bangkok. 

Bus
For inter-city travel, regular public and air-conditioned buses are available. These buses run regularly between Bangkok and provincial cities in Thailand. Three regional bus depots serve the eastern region destinations (Ekamai), northern and northeastern region destinations (Mo Chit), and the southern region (Sai Tai Mai). 

Language

Thai is the national language. English is the next most spoken language and is especially prevalent among the business community in Bangkok. There are four distinct Thai dialects, with the Central Thai dialect being the first language of 75 percent of the population. Many Sino-Thais also speak Chinese dialects.

Health

Medical care is good in Thailand’s urban areas (i.e., Bangkok, Chiang Mai, Phuket, and Pattaya), and facilities exist for routine, long-term, and emergency health care. Basic medical care is available in rural areas, but English-speaking health care providers are rare. Public ambulance service is available throughout Thailand by calling 1669, however there may not be an English-speaking dispatcher. 

Doctors and hospitals often expect immediate cash payment for services. U.S. medical insurance is typically not accepted.  Many hospitals in Bangkok and other major cities will accept standard credit cards. For additional useful health information, contact the International Travelers’ Hotline at the Center for Disease Control (CDC) at 800-232-4636 or 888-232-6348.

If traveling with prescription medication, check with Thailand Customs and the Thailand Food and Drug Administration to ensure the medication is legal in Thailand.

The air quality in Thailand varies considerably geographically and fluctuates with the seasons. Seasonal smog is a problem especially in the winter months. In recent years, the air quality in Bangkok, Chiang Mai, Khon Kaen, Lampang, Nan, and Samut Sakhon have exceeded Thai and U.S. government daily standards for fine particulate matter (PM2.5) for a portion of the year. In Chiang Mai and other northern provinces, annual agricultural burning (February through late April) and forest fires cause days with unhealthy to hazardous air quality based on the U.S. index. In Bangkok environs, airborne dust and auto pollutants are prevalent in the cooler, dry period (December to February). People at the greatest risk from air pollution exposure include:

• Infants, children, and teens.
• People over 65 years of age.
• People with lung diseases such as asthma and chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema.
• People with heart disease.
• People who work or are active outdoors.

For Bangkok and Chiang Mai, U.S. Mission Thailand reports the U.S. EPA’s Air Quality Index (AQI) calculated from PM2.5 data captured by monitors owned and maintained by the Royal Thai government. Various mobile applications are available for tracking the air quality index in nearly all areas around Thailand. The embassy’s Air Quality site is linked here. Air Quality Index (AQI) - U.S. Embassy & Consulate in Thailand (usembassy.gov)

Local Time, Business Hours, and Holidays

The common professional workweek in Thailand is 40 hours per week, consisting of five 8-hour days, Monday through Friday.  Office hours in Bangkok vary to accommodate flextime travel through the city’s notoriously heavy traffic. Common office hours are 8:00 a.m. to 5:00 p.m.  Most business offices are closed on Saturdays and Sundays, although most commercial establishments remain open.  The Commercial Section at the U.S. Embassy in Bangkok is open 7:00 a.m. to 4:00 p.m., Monday through Friday.  The office is closed during lunch from 12:00 noon to 1:00 p.m.

Temporary Entry of Materials or Personal Belongings

Thai Customs Department policy and procedures differ for the temporary entry of goods for business practices and for exhibitions. Duty exemption is valid for temporarily imported goods that will be re-exported within three or six months of the importation date, depending on the entry purpose. 

As a member of the World Customs Organization, Thailand uses ATA Carnet to facilitate the duty exemption of goods temporarily imported for exhibitions, exposition meetings, training, seminars, and international conferences. Imported goods used for free distribution (such as T-shirts, caps, scarves, and pens) or for exchange between attendees of international meetings (related to the development of economy, social, and/or technology aspects) are exempt from duty. The goods should have a logo or symbol related to the meeting, and the value of the goods should be relatively low. 

At present, Thai Customs grants duty exemptions on exhibition goods for use only at exhibition sites, for the repair of professional equipment, product samples, and scientific/technological equipment. If the goods are not re-exported within six months, duties and taxes will then be levied. The entry of temporarily imported goods and exhibit materials can be handled by freight forwarding companies for customs clearance and other required procedures. For further information, please contact ATA Carnet at The Thai Chamber of Commerce and Board of Trade of Thailand or visit the Customs Procedures at the Thai Customs Department website. 

Travelers entering or departing from Thailand are exempt from duty for personal belongings in a reasonable quantity worth no more than 80,000 baht, one liter of spirituous liquor, 200 cigarettes, or 250 grams of cigars or smoking tobacco. For more specific information on the type of goods and steps of customs procedure, please visit the section on “Household Items Import Clearance” on Thailand’s Customs website.
