Thai FDA License Requirements for Foreign Brand Owners: A Guide

Who can file: the Thai entity rule and what it means for you

Thai FDA filings are made by a legal person established in Thailand. For a foreign brand owner with no Thai company, that leaves three practical structures, each with different control and cost.

• **The OEM manufacturer files as the producer.** This is the most common arrangement. The factory that makes your product holds the manufacturing license and submits the product filing under its own name, with your brand name on the product. It is fast and requires nothing from you corporately, but the filing legally belongs to the factory.
• **A Thai distributor or regulatory agent files on your behalf.** A local company acts as the responsible party. Useful when you want the filing separated from the factory, for example to keep the option of switching manufacturers, but it adds a party and a fee.
• **You set up your own Thai company.** Full control and ownership of filings, at the cost of incorporation, accounting, a registered address and, for some license types, physical premises that meet requirements. Brands planning to sell seriously inside Thailand sometimes go this route; brands manufacturing only for export rarely need it at the start.

The decision that matters most is ownership of the filing, because the filing is tied to the formula, the label and the brand name. If the factory holds it and you later move production, the new factory must file again, and you may need the first factory to cooperate on withdrawal. Agree this in writing before development begins: who files, under whose name, who can access the documents, and what happens if the relationship ends. A good OEM manufacturer in Thailand will raise this topic before you do; if they do not, raise it yourself.

Cosmetics: notification rather than a license

For skincare, hair care, make-up, body care and sun care, Thailand follows the ASEAN cosmetic framework. Products are not licensed in the pharmaceutical sense; they are **notified**. The manufacturer or importer submits product details to the Thai FDA, receives a notification number, and takes responsibility that the product meets the regulations. The factory itself must hold a cosmetic manufacturing license for its premises, which is a separate, facility-level requirement you should verify during vetting.

What the notification generally covers:

• Product name and brand, product type and intended use.
• Full formula with ingredient names in the accepted international nomenclature and percentages.
• Manufacturer details and the responsible Thai entity.
• Label artwork meeting Thai labelling rules if the product is sold domestically.

Two points catch brand owners out. First, **sunscreen is a cosmetic in Thailand**, so a sunscreen OEM project goes through notification, but the SPF and related claims must be supported by test evidence and are reviewed more strictly than a moisturiser. Second, ingredient restrictions follow ASEAN lists with Thai specifics, so a formula approved elsewhere can still contain a substance that is restricted or capped in Thailand; your factory's regulatory staff should screen the formula before samples are made, not after.

Claims deserve their own caution. Words that imply treatment, cure or physiological change can push a product out of the cosmetic category into a stricter one. Keep claims cosmetic in nature and agree the claim list with the factory before artwork. Verify current notification procedures and ingredient annexes with the Thai FDA, as they are updated periodically.

Supplements and functional foods: a licensing path with more steps

If you plan to start your own brand of collagen, vitamins, herbal capsules or functional drinks, the regulatory path is longer. These products fall under Thai food law, administered by the Thai FDA food division, and the general structure has two levels.

• **Facility level:** the manufacturer must hold a food production license for the premises and product type, with the production standard the regulations require for that category. When you evaluate a health supplement OEM, this license and its scope (which product types it covers) is the first document to check.
• **Product level:** each product needs its own food registration or notification, depending on the category and risk. Dietary supplements typically require submission of the formula, ingredient specifications, daily dose and usage directions, label artwork, and supporting documents such as ingredient certificates of analysis. Some ingredients require evidence of safety or are limited in dose; novel ingredients can require additional evaluation.

The label is a significant part of the filing: Thai regulations prescribe mandatory statements for supplements, including the warning text that must appear and how nutrition and ingredient information is presented. For supplement manufacturing aimed at domestic sale, expect the factory's regulatory team to spend real time on label compliance, and expect revisions.

Health claims are tightly controlled. Many claims that are common in marketing elsewhere are not permitted on Thai supplement labels or advertising without approval. The safer strategy is to build the brand on ingredient quality, transparency and format rather than outcome promises.

Timelines for food filings vary with category, completeness of documents and current workload, so ask the factory for a realistic range and treat it as an estimate rather than a commitment. As always, confirm the exact requirements for your product with the Thai FDA or a regulatory consultant.

The export-only route: when your product never sells in Thailand

Many foreign brand owners use Thai factories purely to manufacture for other markets. Thai regulations recognise this situation, and products manufactured specifically for export can follow a different path from products sold domestically. The exact mechanism depends on category and is administered by the Thai FDA, so what follows is the general shape, to be confirmed for your case.

In broad terms:

• The factory must still hold the appropriate manufacturing license for its premises; export-only production does not remove facility requirements.
• The product itself may be produced under an export-oriented arrangement that does not require the full domestic filing, provided it is not distributed in Thailand and the export paperwork reflects this.
• Labels can follow the destination market's requirements rather than Thai domestic labelling rules.
• Destination-market registration becomes your responsibility as the brand owner or importer of record in that country, and the factory supplies supporting documents per item when you place the order: formula disclosure, specifications, test reports and, where available, a certificate of free sale or a manufacturing certificate.

The trade-off is important. The export-only route is faster and lighter on the Thai side, but it means your product has no Thai notification or registration number, and some destination authorities or distributors ask for proof that the product is legally sold in the country of manufacture. If you anticipate that request, discuss with the factory whether a domestic filing is worth doing even for an export-focused brand. It can be a sensible investment for markets with demanding import authorities, and unnecessary for others.

Ask the factory to walk you through the exact export documents they issue, and check with your destination-market regulator or clearance partner which ones are required before you choose the route.

Documents to prepare and questions to settle with your OEM

Whichever structure and category apply, the filing is only as fast as the documents behind it. Most delays are not regulatory; they are missing paperwork between brand owner and factory. Prepare the following, and agree who owns each item.

**From the brand owner**

• Company registration documents of your home entity, sometimes legalised or translated, if a Thai agent or your own Thai company will be the filer.
• Brand name and evidence of trademark ownership or application, since the brand on the filing should be one you control.
• The approved claim list and the markets you intend to sell in.
• Label artwork in the destination language, with space reserved for mandatory statements.

**From the factory**

• Copies of the manufacturing license and its scope, and the production standard certification for the facility.
• The full formula with ingredient specifications and supplier certificates of analysis.
• Stability, safety and, where relevant, efficacy test reports.
• Finished-product specifications and batch certificate of analysis.

**Questions to put in the manufacturing agreement**

• Who files, under whose name, and who owns the filing.
• Access rights: can you obtain copies of the full submission at any time?
• Transfer or withdrawal terms if you move production.
• Confidentiality of the formula and whether the formula is yours or the factory's base formula.
• Who bears fees for filing, amendments and renewals.
• MOQ and its relationship to the filing: the standard minimum order of 1,000 units per SKU applies in most Thai OEM arrangements, and some brand owners file several variants under one development project to spread fixed costs.

Settling these before development avoids the most expensive outcome in Thai OEM: a finished, tested product that cannot be shipped because nobody agreed who was responsible for the filing.

Common mistakes foreign brand owners make with Thai FDA filings

Having seen many first projects, the same handful of errors account for most lost time. They are all avoidable with early planning.

• **Assuming a license is one document.** Facility licensing, product notification or registration, and export documentation are separate things. Ask the factory to list each item that applies to your product.
• **Choosing the category by marketing wish rather than by regulation.** A product with treatment claims is not a cosmetic because you would like it to be. The formula, the claims and the intended use determine the category; the category determines the procedure.
• **Finalising artwork before regulatory review.** Mandatory statements, ingredient naming and claim wording all affect layout. Design with a reserved area for compliance text and have the factory's regulatory team review before print.
• **Not confirming filing ownership.** When the factory holds the filing and the relationship sours, moving production becomes a project in itself. Put ownership and transfer terms in writing.
• **Ignoring destination-market requirements until shipping.** Even with a Thai filing, your importer of record abroad has its own obligations. Run the two tracks in parallel.
• **Treating timelines as fixed.** Filing times depend on category, completeness and authority workload. Build buffer into your launch plan and avoid announcing a launch date before the filing is confirmed.
• **Relying on one person's memory of the rules.** Regulations and annexes are updated. Verify current requirements with the Thai FDA or a licensed consultant for each new product.

If you want a manufacturing partner that handles the regulatory track alongside formulation and packaging, firms such as 5FINE (5fineglobal.com) manage production through GMP partner factories and coordinate documentation for the destination market; independent regulatory consultants in Bangkok are another option, and some brand owners use both. Whatever you choose, keep copies of every filed document in your own archive from day one.
