Most sourcing projects do not fail at the price. They fail three months later, when the factory that quoted cannot produce what it quoted for. Almost all of it is visible before you place the order.
Korea has thousands of cosmetics manufacturers. A trade directory will give you a hundred names in an afternoon. The difficulty is not finding candidates — it is telling the difference between a plant that makes your product and a plant that will subcontract it to someone you never meet.
Here is what we check before we put a manufacturer in front of a client.
1. Do they actually make your category?
A plant licensed for skincare is not automatically set up for hair care, and neither is set up for a two-phase or high-pigment colour product. Ask which of your specific formats they run as a routine line, not which they are technically capable of. The answers differ.
Ask for the last three products they made in your category, with launch dates. A plant that has to think about this question has not made it recently.
2. Who owns the formula?
This is the question that causes the most damage later. In an ODM arrangement the manufacturer usually owns the base formula and can sell a near-identical product to another brand. In an OEM arrangement you bring the formula. Between the two sits a large grey area where a formula was "developed for you" but ownership was never written down.
3. Can they produce the documents your market needs?
If you sell into the EU you will need ingredient data and test reports in a form your safety assessor can use for the Product Information File. If you sell into the US, into the Gulf, or into Southeast Asia, the required set differs again.
Many capable Korean plants have never exported to your market and do not hold documentation in that format. That is not a reason to reject them — but it is a cost and a delay you need to know about before you compare quotes. A plant that is 8% cheaper and cannot produce your compliance pack is not cheaper.
4. What is the real minimum order quantity?
MOQ is quoted per product. The number that matters is MOQ per component — per bottle, per cap, per carton, per shade. A 3,000-unit MOQ across five shades is not 600 units a shade; it is usually 3,000 of each unless the packaging is shared.
Ask for the MOQ breakdown by component and by variant. If the answer is a single number with no breakdown, it has not been calculated.
5. Where does the lead time actually go?
A stated lead time of 60 days often means 60 days of production after everything else is finished. The parts that are not counted: formula adjustment rounds, packaging tooling, artwork approval, stability testing, and the component supplier's own lead time.
Ask for the timeline broken into those stages, with the point at which each one starts. That single question tells you a great deal about whether the plant has run an export project before.
6. Will the person quoting still be there in month three?
Many Korean manufacturers quote through an export sales team that hands off to production once the order is confirmed. Find out who your counterpart becomes after the contract, whether they work in English, and what happens when they are away.
7. Go and look
Photographs prove nothing. A plant visit tells you whether the line you were shown is the line that will run your product, whether the facility is as busy as claimed, and whether the people are the ones you have been emailing.
If you cannot travel, someone should go on your behalf and report back with what they saw rather than what they were told. That is the part of this work that cannot be done from abroad — and it is the reason we are based in Korea rather than representing Korea from somewhere else.
The short version
- Ask what they run routinely, not what they are capable of.
- Settle formula ownership in writing before the first sample.
- Confirm they can produce your market's documentation before comparing prices.
- Get MOQ broken down by component and variant.
- Get the lead time broken into stages, with start conditions.
- Meet the person who takes over after the contract is signed.
- Have someone stand in the factory.
