Thailand Dietary Supplements & Functional Food Registration Guide 2026: Food Act B.E. 2522, 13-Digit FDA Numbers, MOPH Ingredient Dossiers, Advertising Clearance (ฆอ.) & Distributor Hostage Defense
Executive Summary: Capturing Thailand's $2.5B Nutraceutical Market Without Sacrificing Regulatory Sovereignty
Thailand represents Southeast Asia's most sophisticated and rapidly expanding market for dietary supplements, functional beverages, and medical nutrition. Driven by an aging demographic, high health awareness, and widespread digital commerce adoption, the consumer appetite for premium foreign health formulations has never been stronger. However, behind this lucrative commercial landscape lies one of the most stringent and rigorously policed regulatory regimes in the Asia-Pacific region.
Every foreign dietary supplement, vitamin, mineral complex, herbal extract, and functional food formulation imported into Thailand is governed strictly by the Food Act B.E. 2522 (1979) and administered by the Food and Drug Administration of Thailand (Thai FDA / สำนักงานคณะกรรมการอาหารและยา), operating under the Ministry of Public Health (MOPH). Commercializing these products requires navigating a mandatory two-tier regulatory framework: first, securing an institutional Importer License (Form Or. 6 / แบบ อ.6) tied to an audited warehouse facility; second, obtaining a bespoke 13-digit Food Serial Number (เลขสารบบอาหาร 13 หลัก) for every single product variant via formal Recipe Registration or E-Submission Notification.
Crucially, international brand owners frequently stumble into severe legal traps: formulating products with active ingredients exceeding strict Thai daily dosage ceilings, launching digital marketing campaigns without mandatory prior advertising clearance (Form Kh.Or. / ใบอนุญาตโฆษณาอาหาร ฆอ.), or surrendering marketing authorizations to local third-party distributors—a catastrophic error that allows local partners to hold the foreign brand hostage. This definitive legal guide provides international corporate counsel, brand founders, and cross-border exporters with the statutory blueprints required to clear Thai FDA hurdles, safeguard proprietary formulas, and retain absolute commercial control.
Strategic Legal Takeaway: A foreign company cannot legally own a Thai FDA food registration directly from abroad. Marketing authorizations can only be issued to a locally registered juristic entity. To prevent local distributors from taking ownership of your product approvals and blocking future market expansion, foreign brand owners must either establish an internal Thai corporate subsidiary (e.g., via BOI TISO or Treaty of Amity) or appoint an independent Local Regulatory Representative (LRR) bound by formal legal trust covenants.
1. Statutory Bedrock: Food Act B.E. 2522 & MOPH Notifications
In Thai jurisprudence, dietary supplements and functional foods are legally regulated as 'Food' rather than 'Pharmaceuticals', yet they are subject to statutory controls that mirror pharmaceutical-grade scrutiny. The foundational statutory authority is the Food Act B.E. 2522 (1979) (พระราชบัญญัติอาหาร พ.ศ. 2522), supplemented by subordinate ministerial notifications that establish binding technical standards.
Core Statutory Provisions of the Food Act B.E. 2522
Section 14: Prohibits the importation of any food for commercial sale without obtaining a formal Food Import License (Form Or. 6 / แบบ อ.6) from the Thai FDA. Importing food without this statutory license triggers criminal penalties under Section 53, including imprisonment for up to 3 years, statutory fines, or both.
Section 15: Sets rigorous statutory qualifications for license applicants and physical storage premises. The applicant must maintain a dedicated commercial storage facility complying with Good Hygiene Practice (GHP) and Good Storage Practice (GSP) standards.
Sections 31 - 33: Grants the Minister of Public Health statutory power to issue notifications classifying foods into four regulatory tiers, establishing quality benchmarks, microbiological parameters, permissible additives, and packaging criteria.
Sections 40 & 41: Enforces an absolute statutory prohibition against false, deceptive, or exaggerated advertising (Section 40) and mandates that all promotional text, packaging claims, digital graphics, and video scripts receive formal pre-broadcast approval (Form Kh.Or. / แบบ ฆอ.) from the Thai FDA before publication (Section 41).
The Governing Ministerial Notifications for Dietary Supplements
The technical evaluation of health supplements is governed by three primary Ministerial Notifications issued by the Ministry of Public Health:
Notification of the MOPH No. 444 B.E. 2566 (2023) Re: Dietary Supplements (ผลิตภัณฑ์เสริมอาหาร): This landmark notification establishes the exhaustive definition, form factors (capsules, tablets, softgels, powders, liquids), standardized production requirements, and statutory safety thresholds for dietary supplements sold in Thailand.
Notification of the MOPH No. 448 B.E. 2567 (2024): Amends ingredient positive lists, updates acceptable botanical extracts, and recalibrates daily dosage limits for essential vitamins and minerals, bringing Thailand into closer alignment with ASEAN harmonized standards while preserving sovereign safety buffers.
Notification of the MOPH No. 446 B.E. 2566 (2023) Re: Food Labeling in Containers (การแสดงฉลากของอาหารในภาชนะบรรจุ): Mandates comprehensive Thai-language labeling specifications, exact ingredient percentage breakdowns, mandatory allergen statements, and Guideline Daily Amounts (GDA) nutrition boxes.
Strategic Legal Takeaway: Customs Enforcement Integration: Thai Customs enforces Thai FDA compliance at all sea, air, and land entry ports via an automated National Single Window (NSW) electronic data interchange. Shipping commercial quantities of supplements without an active Form Or. 6 license and registered 13-digit FDA numbers results in immediate cargo seizure under Section 244 of the Customs Act B.E. 2560 for illegal importation of restricted goods.
2. Phase 1: Establishing the Importer Licensing Foundation (Form Or. 6)
Before any individual product formulation can be submitted for Thai FDA registration, the importing entity must secure an institutional Food Import License (ใบอนุญาตนำหรือสั่งอาหารเข้ามาในราชอาณาจักร - Form Or. 6 / แบบ อ.6), which upon approval yields the official Form Or. 7 (แบบ อ.7) license certificate.
Entity Eligibility & Foreign Ownership Compliance
Under Section 15 of the Food Act, an import license can only be granted to a company registered under Thai law whose registered corporate objectives explicitly include the importation and wholesale distribution of food and dietary supplements. Furthermore, the designated authorized director signing on behalf of the applicant entity must be a legal resident in Thailand or hold a valid Non-Immigrant B visa with an active Thai Work Permit.
Because wholesale trading and retail distribution fall under List 3(14) of the Foreign Business Act B.E. 2542 (FBA), foreign corporations seeking to establish a wholly foreign-owned entity to hold their FDA licenses must implement one of three compliant corporate architectures:
BOI Promotion under TISO (Trade and Investment Support Office): Eligible foreign enterprises can secure 100% foreign ownership from the Board of Investment to conduct international trading, regulatory coordination, and technical support services.
US-Thai Treaty of Amity: American-owned enterprises can obtain Foreign Business Certificates (FBC) granting 100% foreign ownership and national treatment for commercial distribution.
Bona Fide Commercial Joint Venture: A compliant 51% Thai / 49% Foreign corporate structure utilizing dual-class preferred shares for voting control, strictly complying with DBD Anti-Nominee Order No. 2/2569.
Physical Storage Premises & Warehouse Audit Standards
The Thai FDA conducts rigorous on-site physical audits (or virtual photographic inspections) of the designated food storage facility before granting Form Or. 7. The facility must satisfy strict Good Storage Practice (GSP) requirements:
Physical Separation: The storage room must be a fully enclosed, pest-proof, concrete structure physically segregated from living quarters, offices, or chemical storage.
Environmental Controls: Controlled temperature and humidity logging (especially for probiotic cultures, softgels, and temperature-sensitive nutritional compounds).
Pallet Elevation & Organization: All goods must be stacked on pallets raised at least 15 centimeters off the floor and spaced 30 centimeters from exterior walls to facilitate airflow and pest inspections.
Defective Product Quarantine Zone: A clearly marked, physically locked cage or distinct partition dedicated to damaged, expired, or recalled inventory.
Qualified Personnel: Designation of an authorized Quality Control Officer, Pharmacist, or Food Scientist responsible for tracking batch records and Certificates of Analysis.
Strategic Legal Takeaway: Third-Party Logistics (3PL) Solution: Foreign brands establishing their own Thai holding company do not need to buy or lease an expensive standalone warehouse. Thai FDA regulations permit the use of licensed 3PL bonded warehouses and pharmaceutical-grade cold chain logistics providers, provided the 3PL's warehouse floor plan is formally registered under the brand's Form Or. 6 application.
3. Phase 2: Technical Dossier Compilation & The 13-Digit FDA Number (อย.)
Once Form Or. 7 is in hand, the importer can initiate product-specific approvals to obtain the coveted 13-digit Thai FDA Food Serial Number (เลขสารบบอาหาร 13 หลัก). This number must be conspicuously displayed inside the characteristic Thai FDA diamond badge on every commercial container sold in the Kingdom.
The Two Registration Pathways: E-Submission vs. Full Recipe Dossier
Depending on the complexity, novelty, and composition of the formula, product filings are channeled through one of two distinct statutory pathways:
Pathway A: E-Submission Notification (แบบแจ้งรายละเอียดอาหาร - Form SorBor. 5 / แบบ สบ.5): Applicable to standard dietary supplements whose ingredients, botanical extracts, vitamins, and minerals strictly conform to the approved positive lists and dosage ceilings in MOPH Notifications No. 444 and 448. The entire process is handled electronically via the Thai FDA E-Submission portal, with approval typically achieved within 15 to 30 business days.
Pathway B: Full Recipe Registration (แบบขึ้นทะเบียนตำรับอาหาร - Form Or. 18 / แบบ อ.18): Mandatory for products containing novel food ingredients (defined as ingredients without a documented history of human consumption in Thailand for at least 15 years), proprietary bioactive peptides, synthetic novel chemicals, or botanical extracts that deviate from standard specifications. This pathway requires submission to the Food Expert Committee and mandatory safety evaluations by the Department of Medical Sciences (DMSc), with approval timelines extending from 4 to 8 months.
Mandatory International Technical Dossier Checklist
Foreign brand owners must prepare and legalize a comprehensive regulatory dossier from the country of origin:
Certificate of Free Sale (CFS) or Certificate to Foreign Government: Issued by the competent health authority in the manufacturing country (e.g., US FDA, EFSA, TGA, Health Canada, Japanese MHLW), certifying that the exact product formulation is freely sold in the domestic market of origin. Must be notarized and authenticated via Apostille (for Hague Apostille Convention signatories) or Thai Embassy/Consulate legalization.
Certificate of Good Manufacturing Practice (GMP / PIC/S / ISO 22000): Evidencing that the manufacturing plant complies with international standards equivalent to or exceeding Thai ministerial GMP/GHP decrees.
100% Qualitative & Quantitative Formula Breakdown: An official signed declaration from the manufacturer listing 100% of ingredients, excipients, coating polymers, colorants, capsule shell components (bovine gelatin, vegetarian HPMC), and moisture agents, specified down to the exact milligram and percentage.
Finished Product Certificate of Analysis (COA): Must be issued by an ISO/IEC 17025 accredited laboratory within the preceding 12 months, detailing batch-specific testing results for heavy metals (Lead < 1 mg/kg, Arsenic < 2 mg/kg, Cadmium < 0.3 mg/kg, Mercury < 0.02 mg/kg), microbiological contamination (Total Aerobic Count, Yeast & Mold, E. coli, Salmonella, Clostridium, S. aureus), and assay of declared active active compounds.
Manufacturing Process Flowchart: Highlighting extraction ratios (e.g., 10:1 botanical solvent extractions), carrier solvents, heat treatment, and sterilization mechanisms.
Strategic Legal Takeaway: Standardization Trap: A Certificate of Free Sale must match the commercial product name, formula, and manufacturing entity with 100% typographic precision. Any discrepancy between the brand name on the CFS and the packaging art submitted to the Thai FDA will trigger an automatic administrative rejection.
4. Ingredient Compliance & Daily Dosage Limits: MOPH Notification No. 444 & 448
The most frequent failure point for Western, Japanese, and Korean dietary supplements entering Thailand is non-compliance with the Thai FDA's rigid maximum daily intake limits. Formulations engineered for the US or European markets routinely contain mega-dose vitamins or botanical concentrations that violate Thai statutory ceilings.
Statutory Ceilings for Common Active Ingredients
MOPH Notifications No. 444 and 448 delineate the precise boundary between a legally permissible 'Dietary Supplement' and a restricted 'Modern Pharmaceutical Drug':
Vitamin C (Ascorbic Acid): Maximum allowable daily intake in a dietary supplement is capped strictly at 60 mg per day. Formulations offering 500 mg or 1,000 mg per serving are classified as pharmaceutical drugs and cannot be registered under a food import license.
Vitamin D (D3 / Cholecalciferol): Maximum daily intake is capped at 5 mcg (200 IU) to 15 mcg (600 IU) depending on target demographic groupings.
Zinc: Daily elemental zinc is capped at 15 mg per day.
Coenzyme Q10: Permitted up to 30 mg per day in conventional food supplements (up to 300 mg under specialized clinical categories requiring Form Or. 18 evaluation).
B-Complex Vitamins: Thiamine (B1) max 1.5 mg; Riboflavin (B2) max 1.7 mg; Niacin (B3) max 20 mg; Pyridoxine (B6) max 2 mg; Cobalamin (B12) max 2 mcg.
Melatonin & Cannabinoids: Melatonin is classified as a prescription medicine in Thailand and is strictly prohibited as an ingredient in dietary supplements. CBD and cannabis derivatives in imported foods are subject to extreme narcotics cross-border restrictions and cannot be imported in finished retail consumer packages without specialized Narcotics Control Board licenses.
Botanical Extracts & Extraction Solvents
Herbal supplements must utilize botanical species listed on the Thai FDA Positive Botanical Register. Furthermore, the extraction solvent must be specified: standard water (aqueous) or ethanol extractions are readily approved, whereas non-standard organic solvents (e.g., hexane, acetone, methanol) require rigorous solvent residue testing proving parts-per-billion (ppb) compliance.
Strategic Legal Takeaway: Reformulation Advisory: Foreign brands targeting high-volume retail distribution in Thailand typically formulate a dedicated 'ASEAN/Thai SKU' adjusting active vitamin/mineral dosages to meet Thai MOPH ceilings while maintaining the core signature botanical actives that define brand identity.
5. Mandatory Thai Packaging & Nutrition Labeling: MOPH Notification No. 446
Imported dietary supplements cannot be legally distributed in their original foreign language packaging without an approved Thai language overlay label or bespoke localized packaging. Thai law imposes strict layout, typeface, and warning specifications.
Deconstructing the 13-Digit Thai FDA Food Serial Number
The Thai FDA serial number is divided into five specific statutory blocks: [XX-X-XXXXX-X-XXXX]:
Digits 1-2: Provincial location of the importer (e.g., '10' for Bangkok, '12' for Nonthaburi).
Digit 3: Importer status (e.g., '2' designates an imported food product from abroad; '1' designates domestic production).
Digits 4-8: The institutional Form Or. 7 license number assigned to the importing juristic entity.
Digit 9: Running sequence number of the regulatory category.
Digits 10-13: The unique product recipe registration number assigned to that specific formulation.
Mandatory Elements on the Thai Container Label
Thai Product Name: Conspicuously printed in font size proportional to the foreign brand name.
The Thai FDA Diamond Badge: Displaying the 13-digit serial number with high-contrast background visibility.
Full Qualitative & Quantitative Ingredient List: Displayed in descending order of weight (%), identifying functional excipients and capsule shell origins.
Net Weight & Serving Size: Declared in metric units (grams, milligrams, or milliliters), along with total capsule/tablet count.
Complete Importer & Manufacturer Registry: Full statutory corporate name and registered commercial addresses of both the foreign manufacturing facility and the Thai importing company.
Lot Number & Expiration Dating: Clear declaration of Batch Number, Manufacturing Date, and Expiration Date formatted strictly as DD/MM/YYYY.
Mandatory Statutory Warning Text: Every dietary supplement label must display three standardized Thai statutory warnings in bold, bordered text:
1. 'เด็กและสตรีมีครรภ์ไม่ควรรับประทาน' (Children and pregnant women should not consume).
2. 'ควรกินอาหารหลากหลายครบ 5 หมู่ในสัดส่วนที่เหมาะสมเป็นประจำ' (Should regularly consume a varied diet from all 5 food groups in appropriate proportions).
3. 'ไม่มีผลในการป้องกัน หรือรักษาโรค' (Has no effect in preventing or curing disease).
Allergen Disclosure Box: Explicit statement 'ข้อมูลสำหรับผู้แพ้อาหาร: มี...' (Information for food allergic consumers: Contains...) identifying soy, gluten, crustacean, fish, nuts, milk, or sulfites.
Strategic Legal Takeaway: Label Sticker Application: During initial market testing, the Thai FDA permits foreign brands to import goods in original foreign containers and affix approved, tamper-evident Thai adhesive stickers within a licensed bonded warehouse prior to customs clearance, avoiding the immediate expense of full domestic packaging runs.
6. The Section 40 & 41 Advertising Clearance Minefield (Form Kh.Or. / ฆอ.)
Perhaps the most catastrophic trap for foreign consumer health brands entering Thailand is the erroneous assumption that obtaining a 13-digit FDA registration grants the immediate right to market and advertise the product. In Thai corporate law, commercial distribution approval and advertising rights are governed by entirely separate statutory regimes.
The Statutory Framework of Food Act Section 40 & 41
Under Section 40 of the Food Act, making any statement that is false, deceptive, or exaggerates the quality, properties, or therapeutic capabilities of a food or dietary supplement is strictly prohibited.
Under Section 41, ANY person who wishes to advertise the qualities, usefulness, or benefits of a food product through ANY medium—including television, radio, billboards, print magazines, company websites, Facebook, Instagram, TikTok, Line OA, YouTube, and influencer endorsements—MUST submit the exact audio, visual, and textual copy to the Thai FDA for formal examination and obtain an official Food Advertising Permit (ใบอนุญาตโฆษณาอาหาร - Form Kh.Or. / แบบ ฆอ.) prior to broadcasting.
The Thai FDA Cyber Taskforce & Enforcement Crackdowns
The Thai FDA operates an active Cyber Surveillance Unit in coordination with the Consumer Protection Police Division (CPPD / บก.ปคบ.) and the Office of the Consumer Protection Board (OCPB / สคบ.). Automated scraping algorithms actively sweep Thai social media and e-commerce platforms (Shopee, Lazada, TikTok Shop) flagging unapproved health claims.
Blacklisted Words and Concepts in Thai Supplement Advertising:
Therapeutic claims: 'Cures cancer', 'treats diabetes', 'lowers blood pressure', 'eliminates joint pain', 'heals depression'.
Absolute or exaggerated claims: 'Best', 'miracle', '100% effective', 'instant results', 'guaranteed weight loss', 'permanent fat burning'.
Physiological alteration claims: 'Reverses aging', 'detoxifies liver', 'whitens skin in 7 days', 'regrows hair follicles', 'boosts sexual stamina'.
Penalties for Illegal Advertising
Section 70 (Advertising without Form Kh.Or. permit): Fines of up to 5,000 THB per violation, plus daily fines for ongoing broadcasts.
Section 71 (Deceptive or exaggerated advertising): Imprisonment for up to 3 years, statutory fines of up to 30,000 THB, or both, accompanied by mandatory public corrective retraction orders and formal suspension of the underlying Form Or. 7 import license.
Strategic Legal Takeaway: Influencer Marketing Exposure: Foreign brands frequently hire Thai KOLs (Key Opinion Leaders) and micro-influencers to promote supplements on TikTok and Instagram. Under Thai law, both the brand/importer AND the individual influencer face joint criminal liability if the influencer utters unapproved health claims or fails to display the approved ฆอ. permit number on screen.
7. The 'Distributor Hostage Trap' & Corporate Shielding Strategies
In our international corporate advisory practice at GENTLE LAW IBL, the single most damaging crisis we resolve for foreign supplement founders is the 'Distributor Hostage Trap'. This scenario occurs when an eager foreign brand contracts with an established Thai distributor and allows that distributor to use their own existing Form Or. 6 license to register the foreign brand's 13-digit อย. numbers.
Anatomy of the Hostage Trap
Under Thai administrative law, the Food Serial Number is registered under the juristic identity of the importing license holder—not the foreign intellectual property owner. If commercial relations sour—due to underperformance, distributor embezzlement, pricing disputes, or contract expiration—the foreign brand naturally attempts to engage a new distributor.
At this juncture, the foreign brand discovers a legal nightmare: the Thai FDA does NOT permit an identical product recipe, brand name, and formulation to be registered by a second importer while an active registration exists. Furthermore, the Thai FDA will NOT cancel or transfer the existing 13-digit registration without the explicit, notarized written consent of the existing distributor. The distributor demands extortionate 'cancellation fees' (often millions of Thai Baht) or simply refuses, effectively locking the foreign brand out of Thailand for years.
The 3-Tier Gentle LAW Structural Defense
To establish unassailable market sovereignty, foreign brand owners must implement a rigorous corporate defense structure before shipping a single unit to Thailand:
Tier 1: The Foreign-Controlled Thai Holding Entity (The Gold Standard): Establish an internal Thai subsidiary wholly owned by the parent brand (via BOI TISO promotion, US-Thai Treaty of Amity, or a compliant preferred-share corporate JV). This internal subsidiary secures its own Form Or. 6 license and holds 100% of the 13-digit อย. product registrations. The subsidiary then enters into arm's-length commercial supply agreements with local distributors, retaining absolute power to terminate distributors without jeopardizing regulatory assets.
Tier 2: The Independent Local Regulatory Representative (LRR) Model: If the foreign brand is not ready to incorporate a full corporate entity, it must NEVER appoint a commercial distributor as the license holder. Instead, the brand engages an independent, neutral regulatory law firm or certified compliance custodian (an LRR). The LRR holds the Form Or. 6 license on fiduciary trust, providing regulatory custody while appointing non-exclusive commercial distributors to execute sales.
Tier 3: Ironclad Contractual Safeguards & Escrow Powers: If using a distributor-held license is unavoidable, the underlying Distribution Agreement must incorporate mandatory statutory protective mechanisms:
- Irrevocable Power of Attorney (POA): Executing an irrevocable POA authorizing the foreign brand to petition the Thai FDA directly.
- Pre-Signed Form Or. 14 (แบบ อ.14): Executing pre-signed, undated voluntary license cancellation forms deposited into legal escrow.
- Liquidated Damages Clause: Stipulating punitive liquidated damages of 5,000,000+ THB if the distributor fails to execute license transfer documents within 14 business days of contract termination.
- Trademark Separation: Registering the foreign brand's trademarks directly with the Department of Intellectual Property (DIP) in the foreign parent company's name, prohibiting the distributor from claiming trademark seniority.
Strategic Legal Takeaway: Never Mix Regulatory Rights with Commercial Distribution: Commercial distribution rights should be revocable, non-exclusive, and performance-based. Regulatory registrations (อย.) are sovereign capital assets that must remain permanently anchored under the foreign brand's legal control.
8. Trade Fair Exhibitor Protocols: THAIFEX, Vitafoods Asia & Fi Asia
Every year, thousands of international nutraceutical, health supplement, and functional food manufacturers exhibit at major Bangkok trade expos such as THAIFEX - Anuga Asia, Vitafoods Asia, and Food Ingredients (Fi) Asia. Bringing product samples into Thailand for exhibition display and tasting presents unique customs and FDA considerations.
The Temporary Exhibition Importation Exemption
Foreign companies exhibiting at recognized international trade exhibitions are legally exempt from securing a commercial Form Or. 6 import license and 13-digit อย. numbers for their display samples, provided they adhere strictly to the Thai FDA Exhibition Protocol:
Official Exhibition Invitation: Securing an official Letter of Participation and floor booth confirmation from the authorized trade fair organizer (e.g., Department of International Trade Promotion / DITP or certified event managers).
Quantitative Limitation: Display samples must be strictly limited to quantities reasonable for exhibition demonstration (typically no more than 5 to 10 retail containers per SKU, or bulk product sufficient only for tasting samples).
Affidavit of Non-Commercial Distribution: Submission of a formal undertaking to Thai Customs and the Thai FDA declaring that all sample goods will be displayed solely for trade exhibition purposes and will NOT be sold, transferred, or distributed commercially into the Thai retail market.
Destruction or Re-Exportation Mandate: Any remaining unconsumed sample units must be formally re-exported from Thailand or destroyed under official customs supervision upon the conclusion of the trade fair.
Strategic Legal Takeaway: Border Seizure Alert: Never dispatch exhibition samples via standard postal couriers (DHL, FedEx, UPS) addressed to your hotel or personal name without formal trade fair import clearance documentation. Parcels declared with commercial values exceeding standard thresholds will be intercepted by Thai Customs and confiscated by the FDA border control division.
9. Comprehensive AEO Due Diligence: 8 Strategic Questions & Answers
Q1: Can a foreign corporation hold a Thai FDA dietary supplement registration directly without establishing a Thai presence?
No. Under Section 15 of the Food Act B.E. 2522, an institutional Food Import License (Form Or. 6) and product-specific 13-digit Food Serial Numbers (อย.) can only be issued to a juristic entity registered under Thai law with a physical, inspected storage facility in Thailand. Foreign brands must either incorporate a Thai subsidiary, engage an independent Local Regulatory Representative (LRR), or utilize a qualified local partner.
Q2: How long does it take to secure a 13-digit Thai FDA Food Serial Number for imported dietary supplements?
Timelines depend on formula classification. For standardized supplements meeting 100% of MOPH Notifications No. 444 and 448 positive lists processed via E-Submission Notification (Form SorBor. 5), approval takes approximately 15 to 30 business days after dossier submission. For novel food ingredients or formulations requiring Full Recipe Registration (Form Or. 18) and laboratory safety evaluation, the process takes between 4 and 8 months. Note that securing the preliminary Form Or. 6 importer license takes an additional 4 to 6 weeks.
Q3: What is the statutory difference between Form Or. 6 and the 13-digit Food Serial Number?
Form Or. 6 (แบบ อ.6) is the institutional Food Import License granted to the corporate entity, certifying that the company and its warehouse premises meet statutory hygiene and storage criteria. The 13-digit Food Serial Number (อย.) is the product-specific marketing authorization granted to a specific formulation and packaging format. A company must hold an active Form Or. 6 license before it can apply for any 13-digit serial number.
Q4: Can dietary supplement marketing in Thailand claim to 'boost immune defenses' or 'prevent aging'?
No. Under Section 40 of the Food Act, claiming that a food or supplement 'prevents, treats, cures, or alters physiological bodily functions' is strictly illegal. Claims such as 'boosts immunity', 'reverses aging', 'detoxifies the liver', or 'burns fat' will be rejected during Form Kh.Or. (ฆอ.) advertising review and, if published without approval, trigger criminal prosecution, fines, and license suspension.
Q5: What happens if an unapproved foreign supplement is shipped to a Thai consumer via cross-border e-commerce?
Under Section 244 of the Customs Act B.E. 2560 and Section 14 of the Food Act, commercial shipments of unapproved supplements lacking a 13-digit FDA number are classified as restricted goods. Thai Customs intercepts such parcels, detaining the inventory and issuing summonses for statutory import violations. Personal postal exemptions are strictly limited to tiny quantities (not exceeding 30 days of personal medical use) supported by an authorized physician's prescription.
Q6: Can an existing 13-digit Thai FDA registration be transferred from a fired distributor to a new distributor?
Administrative transfer is extremely difficult. The Thai FDA treats the registration as the property of the license holder. Unless the existing distributor voluntarily signs a formal cancellation (Form Or. 14) or assignment deed, the FDA will not transfer the number. This is why foreign brands must retain license ownership through an internal subsidiary or independent regulatory custodian from day one.
Q7: Are CBD, hemp, or cannabinoid extracts permitted in imported dietary supplements in Thailand?
No. While Thailand decriminalized certain domestic cannabis cultivation frameworks, the importation of finished consumer foods, beverages, and dietary supplements containing CBD, THC, or hemp extracts remains strictly prohibited under Ministry of Public Health notifications. Commercial supplement imports must be 100% cannabinoid-free.
Q8: What are the criminal liabilities for company directors if unapproved supplements are sold in Thailand?
Under the Food Act B.E. 2522, authorized company directors bear personal criminal liability for corporate violations. Selling unapproved food carries fines and imprisonment up to 3 years. Unauthorized advertising under Section 41 triggers fines and daily recurring penalties. Furthermore, directors can face border blacklisting and revocation of work permits under Thai immigration statutes.
