How to Choose a Cosmetic Manufacturer in Thailand for a New Brand

Write a one-page project brief before contacting any factory

A factory can only match your needs if those needs are clear. New brands often ask for a price first and only later discover that the quotes are not comparable. A one-page brief fixes this and tells the factory that you're a serious buyer.

Include the following:

• **Product and format:** For example, a gel cleanser in a tube or a serum in a dropper bottle.
• **Target customer and claim direction:** Who it's for, and what you intend to say about it. Claims need to fit the rules of your market.
• **Route:** Existing formula, modified base or new development. These lead to different factory shortlists.
• **Destination markets:** Each market affects ingredients, labels and documents.
• **Quantity:** The standard MOQ is 1,000 units per SKU. State your first-order plan per SKU and your outlook if sales go well.
• **Packaging:** Stock or custom, and who sources it.
• **Must-haves and preferences:** Separate genuine requirements from nice-to-haves, such as vegan formula or a particular certification.

This brief is also your first filter. A factory that reads it and asks clarifying questions is showing you how it thinks. One that replies with a generic catalogue may not have read it closely.

Keep a version for yourself listing your top three priorities. New brands usually can't get everything at once, so you need to know whether formula differentiation, responsiveness or documentation support matters most for this launch. That clarity helps when two factories look equally strong on paper.

Build a shortlist and understand who you're dealing with

Aim for a shortlist of three to five companies. Fewer gives you nothing to compare; more becomes hard to evaluate properly. Useful sources include trade shows such as cosmetics and ingredients exhibitions in Bangkok, referrals from other brand owners, ingredient suppliers, industry associations and online tools such as the Thai manufacturers directory on THAIMOST.

First, establish what kind of company each candidate is. A company may present itself as a factory while its actual role differs:

• **Manufacturer with its own facility:** You can audit the place where your product is made.
• **OEM/ODM brand manager or production partner:** Coordinates development and production through partner factories, which can suit a founder who wants one contact.
• **Trading company or agent:** May add sourcing convenience, but you need to know who actually makes the product.

None of these is automatically right or wrong. The red flag is a company that won't tell you where the product is made. For any model, ask for the actual production site and its documents.

Next, check fit. Ask which product categories the factory handles regularly, whether it runs your format and how comfortable it is with projects at your scale. A factory built around huge volumes might not be the best home for a first brand, while a smaller producer might lack capacity once you grow. Good supplier verification considers both current fit and the next stage of your plan, not just a name with a large facility.

Verification checklist: licences, certificates and the production site

Treat every claim as something to verify. This isn't about distrust; it's standard buying practice. Ask for documents and then check that they match the entity and the site producing your goods.

**Company and site**

• Thai company registration details and the legal name you'll contract with.
• Factory address, and whether it matches the certificates and licences provided.
• Whether the site is licensed for cosmetic production. You can check relevant licensing information with the Thai FDA.

**Certificates**

• For any GMP, ISO 22716 or similar certificate, check the holder's name, site address, scope, issuing body and expiry date.
• Contact the issuing body if something looks unclear.
• Check whether the scope actually covers your product type.

**Quality system**

• Incoming raw material and packaging checks.
• In-process controls and finished goods testing.
• Batch records and retained samples.
• Complaint handling and non-conformance procedures.

**Red flags**

• Certificates with names or addresses that don't match the contracting company.
• Refusal to allow any site visit or virtual tour.
• Inability to explain quality procedures in practical terms.
• Pressure to pay before key terms are written.

A site visit is ideal; if that's not possible, ask for a live video walk-through covering storage, compounding, filling, QC and warehouse areas. For larger commitments, an independent audit may be worthwhile. Requirements for your destination market should also be checked with the relevant authority, because Thai compliance alone won't necessarily cover them.

Test product development and communication with samples

Paper checks show what a factory has; sample rounds show how it behaves. This is where a new brand learns most. Send the same brief to your top candidates and ask about their product development process, including how samples are charged and handled, which varies by factory.

Compare these points as you go:

• **Quality of questions:** Do they ask about climate, packaging and target market, or simply send whatever they have?
• **Sample traceability:** Are samples coded, dated and linked to a version record?
• **Handling feedback:** Send specific comments, then check whether the next round reflects them.
• **Honesty about limits:** A good team will tell you if a claim or ingredient combination is unrealistic.
• **Technical access:** Can you speak with someone who knows the formula, not only the sales team?

Also ask how they'd handle stability and compatibility testing for your chosen packaging, and what evidence you'd receive. Ask what happens when a batch doesn't match the approved sample. How the factory answers tells you much about its quality culture.

For a new brand, responsiveness is a practical factor, but don't confuse quick replies with competence. A slower response containing a thoughtful technical answer may be worth more than an instant yes. Keep every sample, its version number and your written comments in a single place. If a dispute arises later, those records protect you, and they also make it far easier to move forward with the partner you eventually choose.

How to compare quotes without being misled by unit price

Quotes often look very different because they cover different things. The way to compare fairly is to request quotes against the same brief and put them into a single table. If you request quotes from Thai factories through more than one channel, use the same specification each time.

Check whether each quote includes:

• Formula development and sample rounds.
• Bulk product, filling and assembly.
• Primary and secondary packaging, printing and any tooling.
• Stability, compatibility, microbial or other testing.
• Documents for your destination market.
• Incoterm and what the price means, such as EXW or FOB.
• Payment terms, currency and quote validity.
• Handling of defective units and overruns or shortfalls.

Also confirm the MOQ per SKU and whether packaging suppliers set separate minimums, because box or tube quantities can affect your total order. The standard quantity to plan around is 1,000 units per SKU. Prices depend on the product and quantity, and lead times are confirmed when quoting, so don't plan a launch date based on an estimate you've not seen in writing.

A much lower quote is worth examining, not rejecting. It may reflect a different formula concentration, packaging grade or level of testing. Ask what is different before drawing conclusions. When you compare landed costs, include freight, duties, insurance and storage as well. The factory with the lowest unit price may not be the lowest-cost choice once the full picture is visible.

Score the finalists and protect yourself in the contract

When you're down to two or three, use a scorecard. Rate each one from one to five, and add a line of evidence. Weight the categories based on the priorities you set in your brief.

• Product and format experience.
• Fit with your scale and growth plan.
• Verified licences, certificates and site.
• Quality system and traceability.
• Sample quality and technical responsiveness.
• Documentation for your target markets.
• Clarity and completeness of the quote.

Before signing, make sure the agreement covers the essentials: approved sample and specification, ownership of formula and artwork, confidentiality, acceptance criteria, what happens with defective goods, raw material or process changes, payment milestones, and exit terms. Have a lawyer familiar with manufacturing contracts review it, especially for custom formula work.

Keep your first order manageable and treat it as a test of the relationship. Inspect goods against the approved sample, and record how the factory responds to any issue. Some founders prefer a coordinating partner instead of directly managing a factory. In that case, a company such as 5FINE, which manages production through a partner factory network, is one option to evaluate with the same checklist.

Your next step: finish the one-page brief today, shortlist three candidates and send them identical questions. By the time you've compared their answers and samples, the right choice will usually be easier to justify.
