How to Verify a Cosmetic Manufacturing License in Thailand

Understand what a license can and cannot prove

Buyers often ask for the factory's license as if one document settles the matter. In practice, you are verifying four separate layers, and a gap in any of them changes your risk.

• **Legal entity:** Is the company real, registered and active, and is it the same party that will sign your contract and receive your payment?
• **Site and operations:** Is the production site allowed to operate as a factory, and does the address on the paper match where your product will actually be made?
• **Quality system:** Does that site follow a recognised standard such as ASEAN Cosmetic GMP or ISO 22716, and is the certificate current for its scope?
• **Product regulatory status:** Are products properly notified for sale in Thailand, and are they within what your destination market requires?

The point to remember: a valid certificate shows that a specific entity or site met a specific requirement at a specific time. It does not by itself confirm consistent quality for your particular product, and it says nothing about commercial reliability.

Thai rules can change, and terminology varies, so ask the Thai FDA or a local regulatory consultant to confirm which permits apply to your project. Your job as a buyer is not to become a lawyer. Your job is to match documents to the real entity and real site, then ask questions when they do not line up.

The verification checklist: what to request

Send this as a single written request. A manufacturer used to working with export buyers should recognise most of it, although confidentiality limits may apply to some items.

**Company documents** - Company registration certificate and legal name in Thai and English - Registered address and authorised signatory - Tax registration details for your invoices

**Factory and site documents** - Factory operating license or other site permit that applies under Thai rules, with the production address visible - Any documentation for special zones, if relevant - Site map or production floor overview

**Quality documents** - GMP or ISO 22716 certificate, showing certification body, scope, site address and validity dates - Most recent audit summary, if they are willing to share - Quality manual contents or an SOP index

**Product and regulatory documents** - Evidence of how cosmetic notification is handled for Thailand, and who will hold it - Sample Certificate of Analysis format - Example of stability testing report format - Free sale certificate or export documentation they can support, by product

**What good looks like:** Names and addresses match across the documents, dates are current, and scopes cover cosmetics. The team explains plainly what they have and what they do not. A factory that says it holds certain certificates only for particular product lines, and shows you which ones, gives you far more confidence than a broad folder of unexplained logos.

How to cross-check the documents independently

Receiving a PDF is the start, not the finish. Cross-check each document against a source the factory does not control.

**Step 1: Check the company.** Use the Department of Business Development (DBD) records to confirm the legal name, registered status and business address. Compare them with the contract and bank details you have been given.

**Step 2: Check the factory permit.** Factory operations are generally overseen by the Department of Industrial Works (DIW). Ask the factory which permit applies, then check the details with the relevant authority or a local representative. Depending on size and activity, requirements can differ, so ask rather than assume.

**Step 3: Check the quality certificate.** Contact the certification body named on the certificate, or use its public register if one exists, to confirm the certificate number, scope and validity. Check whether the certification body is accredited.

**Step 4: Check notified products.** The Thai FDA provides online information for checking cosmetic product notifications. Try searching a few of the products the factory claims to manufacture or support, and note how it describes its role.

**Step 5: Reconcile.** Build one simple table with columns for legal name, address, permit, certificate, validity date and verification source. Differences such as a sister company name or new address may have an honest explanation, but they should be explained in writing. A local agent or auditor can help with Thai-language checks if you do not read Thai.

Red flags and how to handle them neutrally

A discrepancy does not automatically mean bad intent. Companies restructure, move premises and let certificates lapse during renewal. Treat these items as prompts for further questions, and pause payment until they are resolved.

• **Name mismatch:** The certificate shows one entity, the contract another, and the bank account a third. Ask for the corporate relationship in writing, and make sure the contracting party takes full responsibility.
• **Address mismatch:** The certificate covers a site that differs from the one you were shown. This matters because certification is generally site-specific.
• **Expired or out-of-scope certificate:** Ask for the renewal status and the auditor's contact. A supplement GMP certificate does not cover cosmetics by default.
• **Unclear role:** The company describes itself as a factory but cannot show its production line. It may be a trading company, which can be legitimate as long as it is transparent about who actually makes the product.
• **Documents that are always unavailable:** Confidentiality is reasonable for customer data, but basic site and quality documents should be accessible, possibly under NDA.
• **Payment pressure:** Urgency to pay before verification is complete deserves a firm pause.

Document each query and the answer. Keep your tone factual: you are verifying, not accusing. A professional manufacturer usually respects a structured process, because it signals that you will be a serious customer and a more organised long-term partner.

Going beyond paper: audits, samples and contract protection

Documents show compliance on paper. To understand how a factory really operates, add practical checks in proportion to your order size and risk.

**Virtual or on-site audit** Ask to see raw material storage, weighing, mixing, filling, the QC lab and retained samples. Request a batch record example with confidential details hidden. Look for traceability from material receipt to finished goods. For larger projects, a third-party audit is often worth considering.

**Pilot and testing** A pilot batch and stability testing can reveal issues that paperwork cannot. Verify that your approved sample and production specification are recorded.

**Contract protection** - A clause stating the factory's legal name and production address - A requirement to notify you of site, subcontractor or certification changes - Your right to audit - Rules for handling out-of-specification batches - Clear formula ownership and confidentiality terms

Commercial terms also come into play. When MOQ matters, plan around the standard of 1,000 units per SKU, and confirm price and timing in the written quotation. You can request quotes from Thai factories directly, or use THAIMOST as one way to compare Thai OEM/ODM factories, though verification on any platform reduces risk and does not replace your own diligence. Next step: send the checklist to your shortlisted factories and record the answers in the table above.
