If you're sourcing both a skincare line and a wellness supplement from Thailand, you'll quickly notice the paperwork isn't the same. A factory that's well set up for lotions and serums may not be the right fit for capsules or powders, and vice versa. Understanding the cosmetic factory vs supplement factory certification differences upfront saves you from re-auditing, re-negotiating, or worse, discovering mid-production that your chosen facility isn't actually licensed for the category you need. This guide breaks down what to check, where the two tracks diverge, and how to vet a partner correctly the first time.
Why cosmetics and supplements are regulated differently
Cosmetics (skincare, makeup, baby care, home care) and dietary supplements fall under different regulatory logic almost everywhere, including Thailand. Cosmetics are topical products, so the emphasis is on manufacturing hygiene, formulation safety data, and labeling claims that stay within cosmetic (not therapeutic) boundaries. Supplements are ingested, so facilities typically need to demonstrate controls closer to food or pharmaceutical standards: ingredient traceability, dosage accuracy, and stricter microbial and contaminant testing. A factory built around GMP for cosmetics (often referenced against ASEAN Cosmetic GMP or ISO 22716) is not automatically qualified to produce supplements, which usually sit under separate GMP scopes for health products or food supplements. When you're comparing Thai OEM/ODM factories, always ask which GMP scope their certificate actually covers — some facilities run dual lines with separate certifications for each category, others specialize in only one.
What to verify for a cosmetic manufacturing line
For skincare, makeup OEM, baby care OEM, and home care OEM projects, the core documents to request are the cosmetic GMP certificate scope (does it cover the product type you need — liquid, cream, powder, aerosol?), a product safety assessment or PIF-equivalent documentation for the formula, and any existing certifications attached to raw materials if your buyer market requires them. Because cosmetics claims are closely watched, also check how the factory's regulatory team reviews label wording before production — this is a practical sign of a team that understands the category, not just the machinery. Document control matters here too: ask to see a sample batch record and a certificate of analysis format so you know what you'll actually receive with each order.
What to verify for a supplement manufacturing line
Supplement production usually demands a tighter documentation trail. Expect to ask about: GMP certification specific to health products or dietary supplements (distinct from the cosmetic GMP certificate), raw material certificates of analysis with potency or purity data, stability testing relevant to the dosage form (capsule, tablet, sachet, liquid), and any allergen or cross-contamination controls if the facility also handles other product types. If a supplement factory can only show you a cosmetic GMP certificate, that's a gap worth asking about directly rather than assuming it extends to ingestible products — it generally does not.
Red flags when a factory claims to do both categories
Some manufacturers genuinely run separate, properly certified lines for cosmetics and supplements. Others market themselves as 'full category' without being transparent about which certificate applies to which product line. Red flags include: a single GMP certificate presented as covering everything, reluctance to show category-specific documents, no clear separation of production areas between topical and ingestible products, and vague answers about which regulatory scope their quality team actually audits against. None of this means a factory is acting in bad faith — paperwork gaps are common and fixable — but it does mean you should ask before committing, not after the first production run.
A practical verification checklist
Before signing with any Thai skincare suppliers or a combined cosmetic-and-supplement manufacturer, run through this: 1) Request the GMP certificate and confirm its exact scope and expiry. 2) Ask which production lines are dedicated to cosmetics versus supplements, and whether they're physically separated. 3) Request a sample certificate of analysis and batch record format. 4) Confirm how raw material sourcing and traceability are documented for your specific product. 5) Clarify export documentation support, since requirements vary by destination market — always check with your own country's import authority as well. 6) Remember MOQ for OEM/ODM manufacturing is typically set at 1,000 units per SKU; pricing and timelines are confirmed at the quoting stage based on your specific product and volume.

FAQ
Frequently asked questions
Can one factory legally produce both cosmetics and supplements?
Yes, some facilities operate separate certified lines for each category. What matters is confirming that each line has its own appropriate GMP scope and documentation, rather than assuming one certificate covers both product types.
Is cosmetic GMP the same as supplement GMP in Thailand?
No. They are distinct certification scopes. Cosmetic GMP is generally referenced against standards like ASEAN Cosmetic GMP or ISO 22716, while supplements fall under separate health product or food supplement GMP requirements. Always ask which scope a certificate actually covers.
What documents should I ask for before placing an order?
At minimum: the GMP certificate with its scope and expiry, a certificate of analysis format, batch record samples, and raw material traceability documentation relevant to your product category.
Does certification affect import clearance in my country?
It can, depending on your market's requirements for cosmetics versus supplements. It's best to check directly with your own country's customs or regulatory authority about what documentation they require for each product type.
