If you've been sourcing from a skincare manufacturer in Thailand, you've probably seen a string of digits called a "notification number" attached to a product or formula. Buyers often assume it works like a certificate of quality — it doesn't. Understanding what this number actually confirms, and what it leaves out, is one of the simpler but most overlooked steps in supplier verification. This guide breaks down what the notification number tells you, what it doesn't, and how to use it sensibly when you request quotes from Thai factories.
What the notification number actually is
In most ASEAN markets, including Thailand, cosmetic products don't go through a pre-market approval process the way drugs do. Instead, the manufacturer or brand owner submits a notification to the relevant authority declaring the product category, formula type and responsible party, and receives a notification number in return. This number confirms that a notification was filed and logged in the system — it is an administrative record, not a safety or efficacy approval. It tells you a product exists on paper with a declared owner and category, nothing more.
What it does NOT confirm
A notification number does not verify that the formula was tested, that the factory follows good manufacturing practice, or that the ingredients match what's on the label. It also doesn't confirm the current legal status of a product years after filing — notifications can lapse or be withdrawn. Treat it as one data point among several, not as a substitute for checking the facility itself, requesting batch documentation, or confirming who the notification holder actually is.
How to check a notification number before trusting it
A basic verification checklist: ask who holds the notification (the factory, the brand, or a third-party agent), request a copy of the notification document rather than just the number, confirm the product category matches what you're ordering, and check the filing date against your expected production timeline. For products destined for export, it's worth remembering that a Thai notification does not automatically clear your product for sale elsewhere — check with the relevant customs or regulatory body at your destination separately.
Where this fits into broader supplier verification
The notification number is a useful starting point, but real supplier verification goes further: facility walkthroughs or video audits, sample testing, checking how the factory handles documentation for export, and understanding their track record with brands similar in size to yours. Factories that readily share notification documents, SDS sheets and batch records tend to be more transparent overall — reluctance to share this kind of paperwork is a reasonable red flag worth asking about directly.
Using this knowledge in global sourcing conversations
When you're doing global sourcing across multiple countries, it helps to standardize the questions you ask every factory, regardless of where they're based: who holds the notification, what documentation is provided per batch, and whether certificates are issued per SKU or per product line. Asking these questions consistently makes it easier to compare quotes and documentation across a partner factory network rather than evaluating each supplier on different terms.
Putting it together when you request quotes
Once you understand what the notification number does and doesn't cover, you're in a better position to ask the right follow-up questions when you request quotes from Thai factories — for example, whether notification and supporting documents are included per SKU, and what the standard MOQ of 1,000 units per SKU means for your documentation needs.

FAQ
Frequently asked questions
Is a cosmetic notification number the same as a safety certification?
No. It confirms that a notification was filed and recorded with the authority, not that the formula has been independently tested or certified safe.
Can I use a Thai notification number to sell in another country?
Generally no — notification systems are market-specific. Check with the regulatory or customs body in your destination market for their own requirements.
Who should hold the notification — the factory or my brand?
This varies by arrangement and should be clarified in your contract. Ask the factory directly who the notification holder is and request the supporting document, not just the number.
How do I confirm a notification number is still valid?
Ask the factory for the original filing document and date, and confirm the product category and responsible party match your current order before relying on it.
