    Thai Food & Drug Law: FDA Rules for Food, Medicines & Cosmetics

    How Thailand's FDA regulates food, medicines, cosmetics and medical devices — licensing, registration, importing medication, and the penalties for counterfeit or unregistered products.

    Overview

    Thailand's food and drug regime is run by the Food and Drug Administration (the Thai FDA, 'อย.') under the Ministry of Public Health, which licenses and registers consumer health products — food, medicines, cosmetics and medical devices. For medicines the governing statute is the Drug Act B.E. 2510 (1967). It makes it an offence to produce, sell or import modern medicines without an FDA licence (section 12), and separately bans counterfeit, substandard, deteriorated and unregistered medicines (section 72). Penalties range from modest fines for licensing lapses to imprisonment of three years to life for manufacturing counterfeit medicines. Medicines generally must be registered with the FDA (a 'drug-formula registration' under section 79, subject to exceptions such as pharmaceutical chemicals and herbal drugs), and are graded by class — household remedies that anyone may sell, 'dangerous' drugs (ยาอันตราย) that must be sold at a pharmacy with a pharmacist present, and specially-controlled drugs (ยาควบคุมพิเศษ) that are the most tightly restricted and, under FDA regulations, sold only to or on the order of a doctor — with the products in each class fixed by ministerial notification. Food is governed by the Food Act B.E. 2522 (1979), under which the FDA registers food products and controls unsafe food such as adulterated, substandard or mislabelled products; cosmetics and medical devices have their own FDA statutes (the Cosmetics Act B.E. 2558 and the Medical Device Act B.E. 2551). This hub covers the regulation of legal consumer products — it is not about illegal narcotics (see Narcotics & Drug Law) or the practice of medicine (see Health & Medical Law). For foreigners the issues that bite most are bringing personal medication into the country (a traveller may carry up to a 30-day personal supply without a licence under section 13, but controlled medicines need prior approval and can be seized at the airport), ordering unregistered medicines or supplements online, and selling food, supplements or cosmetics — which requires FDA registration and compliant, non-deceptive advertising. Specific figures, product classifications and registration rules are set by regulation and change over time, so confirm the current position with the Thai FDA before relying on any amount or category.

    Counterfeit Medicines

    severe

    Making, selling or importing fake, falsely-labelled or grossly off-specification medicines.

    Drug Act B.E. 2510 §72(1), Drug Act B.E. 2510 §73, Drug Act B.E. 2510 §117, Drug Act B.E. 2510 §119•Max: Manufacturing counterfeit medicine: 3 years to life imprisonment and a fine of THB 10,000–50,000 (section 117). Selling or importing it: 1 to 20 years and a fine of THB 2,000–10,000 (section 119); a lower fine applies where the seller genuinely did not know the medicine was counterfeit.

    Unregistered Medicines

    serious

    Making, selling or importing a medicine that has not been registered with the Thai FDA.

    Drug Act B.E. 2510 §72(4), Drug Act B.E. 2510 §122, Drug Act B.E. 2510 §79•Max: Up to 3 years imprisonment or a fine of up to THB 5,000, or both (section 122). Medicines must generally carry a drug-formula registration (section 79), subject to the section 79 bis exceptions (e.g., pharmaceutical chemicals, herbal drugs and samples).

Where the seller did not know, imprisonment falls away and only the fine (same ceiling) applies. Manufacturing substandard medicine is treated more severely under section 118 (2–5 years and a fine of THB 4,000–20,000).

    Illegal Medicine Advertising

    moderate

    Frequently Asked Questions

    Can I bring my prescription medication into Thailand?

    Yes — a traveller may carry up to a 30-day personal supply without a licence (Drug Act section 13). Controlled medicines are tightly restricted: some need prior approval, and others (e.g., amphetamine-type ADHD stimulants) cannot be brought in at all.

    Can I buy medicines over the counter in Thailand?

    It depends on the drug's class. Household remedies are sold freely, 'dangerous' drugs must be sold at a pharmacy with a pharmacist present, and specially-controlled drugs are the most restricted (sold only to or on a doctor's order under FDA rules).

    Do I need FDA approval to sell food or dietary supplements in Thailand?

    Usually yes. Most packaged food and dietary supplements must be FDA-registered, carry the registration number, and avoid unapproved health claims.

    What are the penalties for counterfeit or unregistered medicines in Thailand?

    Counterfeit medicines carry 3 years to life for manufacturing and 1–20 years for selling or importing. Unregistered medicines carry up to 3 years or a fine up to THB 5,000.

    Are health claims in advertising allowed in Thailand?

    Medicine advertising needs prior approval and may not be false or exaggerated; breaching the rules carries a fine of up to THB 100,000 under the Drug Act.

    Is Food & Drug law the same as narcotics or cannabis law?

    No. Food & Drug law covers legal FDA-regulated products (food, medicines, cosmetics, devices). Illegal drugs fall under narcotics law, and cannabis has its own regime.

    When Legal Representation Matters

    If you are facing a food & drug law matter that involves investigation, arrest, litigation, or formal proceedings, professional legal representation becomes essential.
