How to Request Samples From a Cosmetic Manufacturer: A Checklist

Before you ask: verify the factory and write the brief

A sample request is the first real transaction with a manufacturer, so two things should happen before it is sent. The first is basic supplier verification. Confirm the company is registered in Thailand through the Department of Business Development records, ask which quality standards the production site operates under, and request the names of the person handling your project and the person responsible for quality. A factory that cannot answer these in a day is telling you something.

The second is a written brief. Without one, the factory will send whatever is closest in its catalogue, and you will have no way to judge whether the sample reflects what they can do for you. A one-page brief should include:

• **Product type and form:** serum, gel-cream, sunscreen lotion, cleansing balm.
• **Target market and customer:** country of sale, skin type, age range, price tier.
• **Hero ingredients and exclusions:** what you want in, what must stay out (for example fragrance, alcohol, specific preservatives).
• **Texture and sensory goals:** fast-absorbing, matte finish, light scent, no tackiness after ten minutes.
• **Claims you intend to make:** so the factory can flag what the formula and your market's rules allow.
• **Packaging intent:** airless pump, dropper, tube or jar, because compatibility affects the formula.
• **Expected first order:** production is planned per SKU and the standard minimum order quantity is 1,000 units per SKU, so state whether you are planning one SKU or a range.

Send the same brief to every factory you approach. That is the only way to compare samples from different Thai OEM/ODM factories on equal terms.

Which type of sample to request

Manufacturers produce several kinds of samples, and asking for the wrong one wastes weeks. Be explicit about which you want:

• **Stock or catalogue sample.** An existing ready formula (ODM) the factory already produces. Fast, often low-cost, useful for judging the factory's general quality and the base you might adapt. Ask for the ingredient list with it.
• **Custom lab sample.** A bench-scale batch made to your brief. This is where you evaluate texture, scent, colour and initial performance. Expect two to four rounds of revision; ask how many rounds are included and how feedback is handled.
• **Pre-production or pilot sample.** Made on production equipment, in your intended packaging, after the formula is locked and tested. This is the sample you sign off against before the full run, and the one your QC team compares deliveries to later.
• **Packaging sample.** The empty bottle, pump or jar, with or without decoration. Request it early so compatibility testing can begin.
• **Counter sample.** A retained duplicate of the approved sample kept by both sides as the reference standard for production.

For a first contact, requesting one or two stock samples in your category plus a quote for custom development is a sensible sequence. It shows you the factory's baseline quality before you invest in rounds of custom work. When you request quotes from Thai factories alongside samples, ask them to state the sample type they are sending so there is no confusion later about what was evaluated.

Fees, shipping and timing: what is normal

Buyers are often unsure whether paying for samples is a red flag. It is not. What matters is that terms are clear and proportionate.

• **Stock samples** are frequently provided free or at a nominal charge, with the buyer covering courier costs. Expect to supply a courier account or pay shipping in advance.
• **Custom lab samples** usually carry a development fee that reflects chemist time and raw materials. Some manufacturers credit this against the first production order; ask whether yours does and get it in writing.
• **Pilot samples** on production equipment may involve set-up charges, especially if custom packaging or printing is involved.
• **Shipping** of cosmetics internationally can require specific documentation, and products with alcohol or pressurised components have restrictions. Ask the factory which courier they use and what declaration accompanies samples.

Timing depends on whether the formula exists, raw material availability and how many revision rounds you need, so it is confirmed when the factory sees your brief rather than promised in advance. What you can control is responsiveness: a buyer who takes three weeks to give feedback on a sample should not expect the factory to hold capacity.

Two practical habits help. First, agree in writing what the sample fee covers, how many revisions are included, and who owns the resulting formula. Second, keep a simple log with the date requested, date received, batch reference and fee for every sample. When you are comparing a skincare manufacturer in Thailand against two others, that log becomes the basis of a fair decision rather than a memory of who replied most warmly.

How to evaluate a sample methodically

A sample evaluated by one person, once, on the back of a hand, produces an opinion. A sample evaluated against a checklist, by several people, over time, produces data. Use the following and record results for every factory in the same format:

• **Documentation on arrival.** Ingredient list in INCI order, batch or sample reference, date made, storage instructions, and any available test data. Missing paperwork at sample stage predicts missing paperwork at production stage.
• **Appearance and odour.** Colour, clarity, uniformity, separation, and whether the scent matches the brief. Check again after two and four weeks at room temperature.
• **Texture and application.** Pick-up, spread, absorption time, residue, pilling under other products, feel after thirty minutes. Test on at least three people with different skin types.
• **Performance against the claim.** Hydration feel, mattifying effect, coverage or whatever the hero claim is. Keep expectations realistic for a lab sample; formal efficacy testing comes later.
• **Compatibility with your packaging.** Pump it, squeeze it, leave it in the intended container for several weeks. Watch for clogging, leakage or change.
• **Climate test.** Leave a portion in a warm place and in a cool place; note changes. Products that will sell in hot, humid markets should be tested there.
• **Stability signals.** Any separation, colour drift or odour change within a few weeks is a flag to raise with the chemist before investing in further rounds.

Give feedback in the same structure. Specific comments such as tacky after eight minutes on oily skin, scent fades within an hour, or pills under sunscreen are actionable; the comment not quite right is not. Good product development depends on the quality of this loop.

Red flags and common buyer mistakes

Sample stage is where problems are cheapest to catch. Watch for these on the factory side:

• **No ingredient list or vague descriptions** such as herbal complex without INCI names.
• **Samples that do not match the brief** with no explanation of why.
• **Pressure to place a production order before stability or compatibility checks.**
• **Unwillingness to state which standards the production site operates under**, or claims that every product automatically carries every certification.
• **Inconsistent samples** between rounds without a change log.
• **No clarity on formula ownership** when a development fee is charged.

And these on the buyer side:

• **Sending a different brief to each factory**, which makes comparison impossible.
• **Approving a sample after one application.** Live with it for weeks, in the climate where you will sell.
• **Skipping the packaging sample** and discovering incompatibility after the bulk is made.
• **Treating the lab sample as the production standard.** Insist on a pilot sample from production equipment before the full run.
• **Chasing many factories at once.** Three well-briefed candidates are easier to evaluate than ten.
• **Ignoring the regulatory check.** Confirm with the relevant authority or a regulatory consultant in your market which tests and documents your product will need, so the sample stage covers them.

A buyer who avoids these mistakes usually reaches a confident decision after one round of stock samples and two or three rounds of custom samples, with a clear paper trail to show investors or partners.

A sample request template you can adapt

Below is a structure that works as an email or a message on a B2B platform. Keep it short, specific and the same for every factory.

**Subject:** Sample request: [product type] for [market]

**Company and contact:** registered name, country, role, website if available.

**Project summary:** one paragraph describing the product, target customer, price tier and launch plan, including that the first order would be at the standard 1,000 units per SKU for [number] SKUs.

**Sample requested:** stock sample in [category] and/or custom lab sample to the attached brief; packaging sample for [format].

**Documentation requested with the sample:** INCI list, sample reference and date, storage guidance, available test data, and a note of which quality standards the production site operates under.

**Commercial questions:** sample fee and what it covers, number of revision rounds included, whether the fee is credited against production, formula ownership, and an indicative quotation for production and testing based on the brief.

**Logistics:** delivery address, courier account if you have one, and any import note for your country.

**Closing:** your decision timeline and how you prefer to communicate.

Send it to a shortlist of two or three verified candidates. If you are starting from scratch, a platform such as THAIMOST that lists Thai manufacturers with verification badges can shorten the shortlisting step, while a managed-production partner such as 5FINE, which runs projects through partner GMP factories rather than a single site, can handle samples, packaging and documentation under one contact. Either way, the checklist above remains your responsibility, and it is what turns a sample into a decision.
