Leading OEM/ODM Sunscreen Factories in South Korea (2026)

A buyer’s comparison of South Korea’s three largest, independently verifiable sunscreen contract manufacturers, for brand teams briefing a factory on suncare formulation, certification and export capacity in 2026.

Quick answer

South Korea’s sunscreen OEM/ODM sector is anchored by three companies large enough and evidenced enough to independently verify in 2026: Cosmax, Kolmar Korea and Cosmecca Korea. Cosmax is the only one of the three holding a US FDA OTC drug certification for its dedicated OTC Lab, making it the strongest fit for brands selling sunscreen into the US market. Kolmar Korea runs a proprietary UV Tech Innovation Lab and already manufactures sunscreens for named independent K-beauty brands. Cosmecca Korea carries the broadest certification stack of the three — seven distinct standards, including vegan cosmetics and AEO customs status — but is the smallest by scale. Which one fits depends on the target market and whether a buyer needs US regulatory reach, formulation novelty, or export-documentation depth.

Key takeaways

• Only three South Korean sunscreen OEM/ODM manufacturers met this review’s verification screen for 2026 — all three are large, independently confirmed cosmetics ODM groups, not marketplace-only listings.
• Cosmax is the sole big-3 manufacturer with a US FDA OTC drug certification, earned in 2016 through a dedicated OTC Lab targeting the US$2.6 billion US sun-care market.
• Kolmar Korea’s UV Tech Innovation Lab is described as the world’s first hybrid composite sunscreen stabilisation technology, and the company is independently reported to manufacture sunscreens for Beauty of Joseon and Skin1004.
• Cosmecca Korea holds the widest certification spread (ISO 9001, 14001, 45001, 22716, OHSAS 18001, AEO and Vegan Cosmetics) despite ranking third by scale, making it the specialist pick for compliance-heavy exporters.
• Sunscreen in South Korea is regulated as a “functional cosmetic” by the Ministry of Food and Drug Safety (MFDS), not an ordinary cosmetic — a distinction that shapes what documentation a factory needs to support an SPF/PA claim.

Who this list is for

This review is for brand owners and private-label buyers evaluating South Korea as a sunscreen or suncare manufacturing base in 2026 — whether the goal is a US-market SPF product, a K-beauty-style hybrid skincare-sunscreen, or a large-volume export order. It assumes the buyer already knows they want a Korean factory and needs to compare the handful of manufacturers large and evidenced enough to brief with confidence, rather than a directory of every registered cosmetics workshop in the country. Buyers still weighing up a manufacturing base can browse this site’s wider beauty, skincare and personal care manufacturer coverage before narrowing to Korea specifically.

Eligibility rules

To qualify for this list, a company had to be an operating manufacturer with a verifiable corporate registration and a live, independently verifiable South Korean website, offering third-party OEM/ODM contract manufacturing of sunscreen or sun-care products specifically — not just general skincare with sunscreen as an incidental line. Every candidate’s certifications, facility claims and product scope were checked directly against the company’s own site plus independent trade or business press, not taken from self-reported marketing copy alone. Where a founding year or certification could not be independently confirmed, it is recorded as unconfirmed rather than estimated. The screen was applied before any company was scored — no company was added to raise the count, and none was dropped to shorten it.

The list at a glance

How South Korea’s functional-cosmetic system changes what a sunscreen buyer should ask for

Unlike a basic moisturiser or cleanser, sunscreen sold in South Korea is classified as a “functional cosmetic” (기능성화장품) under the Cosmetics Act, with the Ministry of Food and Drug Safety (MFDS) as the regulator overseeing the category. That classification exists because an SPF or PA rating is a performance claim, not a marketing adjective — so a factory manufacturing under this framework is expected to hold or generate supporting efficacy data behind the number printed on the label, in a way a plain moisturiser never has to. For a private-label buyer, the practical takeaway is that “we can hit SPF 50” is not a complete answer from a Korean sunscreen OEM/ODM partner: a serious manufacturer should be able to describe how it substantiates that figure, and whether that documentation travels with the product into the buyer’s own target market, where a separate regulator (the US FDA, the EU’s Cosmetic Products Regulation, or Malaysia’s NPRA, depending on where the finished product ships) will apply its own rules on top of Korea’s. This is precisely where Cosmax’s dual Korean-and-US-FDA-OTC posture stands apart from a manufacturer that is only built around the domestic MFDS pathway — it is one thing to be compliant at home, another to already carry a second country’s regulatory certification into the conversation.

Cosmax

Cosmax’s differentiator is regulatory reach beyond Korea: it is the only manufacturer on this list with a US FDA OTC (over-the-counter drug) certification, obtained in 2016 through a dedicated OTC Lab built specifically to target the US$2.6 billion US sun-care market — a formal designation neither Kolmar Korea nor Cosmecca Korea holds. Founded in 1992 and headquartered in Seongnam-si’s Pangyo Innovation Valley, Gyeonggi-do, Cosmax has grown into what independent reporting and its own site describe as the largest cosmetics ODM in South Korea by volume and client count, developing and producing for 18 of the world’s top 20 beauty companies. Its OTC Lab covers the full research-to-manufacturing process for sun care, alongside SPF skincare, cushion foundations, general skincare, makeup and hair care. Certifications extend past the US to a Health Canada OTC certification and an MUI (Indonesian Halal) certification, and its facility footprint spans Korea, China, the USA, Indonesia and Thailand. Best suited for: brands planning to launch or scale a sunscreen SKU specifically for the US market, where OTC drug-monograph compliance is a real gatekeeping requirement, not a nice-to-have. Not ideal for: very small first-time brands, since neither MOQ nor lead time is company-disclosed, and Cosmax’s scale profile points toward larger, more established buyers. Company-stated facility capacity claims (client roster, plant locations) are labelled as such; the FDA and Health Canada OTC certifications are independently reported via PR Newswire, not self-declared only.

Kolmar Korea

Kolmar Korea’s differentiator is technical: its UV Tech Innovation Lab is described as having developed the world’s first hybrid composite sunscreen stabilisation technology, and independent industry reporting credits the company with manufacturing sunscreens for named indie K-beauty brands including Beauty of Joseon and Skin1004 — a track record of shipping product for brands a Western buyer may already recognise. Founded in 1990 and headquartered in Sejong with an R&D complex in Seoul, Kolmar Korea holds Korea’s CGMP designation as both the country’s first and second CGMP-conforming cosmetics company. Its scale is substantial: three manufacturing plants, over 1,300 employees, and 2025 consolidated revenue of 2.72 trillion KRW, making it the first cosmetics ODM in Korea to be named to the country’s large-conglomerate business-group ranks, per The Korea Times. Beyond sun care, its product scope covers general skincare and cosmetics ODM work. Best suited for: brands wanting a sunscreen formulated as part of a broader skincare-hybrid product — essence-sunscreens, cushion SPF, or similar categories where Kolmar’s stabilisation technology is the selling point — and brands reassured by working with a manufacturer already producing for recognisable K-beauty names. Not ideal for: buyers who specifically need the US OTC drug-certification pathway Cosmax already holds, since Kolmar Korea’s certification profile (CGMP) is narrower and domestically focused by comparison. The Beauty of Joseon and Skin1004 manufacturing relationship is sourced to independent industry reporting rather than Kolmar’s own site, and is presented here on that basis.

Cosmecca Korea

Cosmecca Korea’s differentiator is certification breadth: across the three companies on this list it carries the most independently-listed standards — ISO 45001, OHSAS 18001, ISO 14001, ISO 9001, ISO 22716 (Cosmetic GMP), AEO (Authorized Economic Operator) and a Vegan Cosmetics certification — seven in total, all confirmed via its TradeKorea company profile. Headquartered in Eumseong-gun, Chungcheongbuk-do, Cosmecca is described in industry sources as the third-largest Korean cosmetics ODM by market share and is credited with pioneering BB cream production, a category now standard across Asian cosmetics. Its founding year could not be independently confirmed — one B2B directory profile states 1990, an industry summary implies 1999 — and is recorded here as unconfirmed rather than guessed. Product scope covers sun care and sunscreen alongside skincare, men’s skincare, a wide makeup range (BB cream, point makeup, lipstick, powder), bath and body, fragrance and hair care, and the company exports to China, Thailand, Vietnam, Japan, Taiwan, Hong Kong and the USA. Best suited for: exporters who need a manufacturer whose paperwork — customs status (AEO), environmental (ISO 14001), safety (ISO 45001/OHSAS 18001) and vegan formulation credentials — is already assembled and independently verifiable, reducing due-diligence friction on the buyer’s side. Not ideal for: a brand chasing the largest possible production scale or the deepest single-category sunscreen specialisation, since Cosmecca’s scale-and-capacity and product-specialisation scores trail both Cosmax and Kolmar Korea in this review’s scoring.

How they compare

All three manufacturers clear the same eligibility bar — verifiable registration, a live company site, and genuine sunscreen OEM/ODM capability — but they separate sharply on what kind of evidence they lead with. Cosmax and Kolmar Korea are the scale players: both hold multi-country facility footprints or multi-plant domestic operations, and both score a maximum 25/25 on this review’s scale-and-capacity dimension. Cosmecca is the specialist by comparison, trailing on scale (18/25) but leading decisively on certification (28/30 versus Cosmax’s 24/30 and Kolmar Korea’s 18/30) — its seven independently-confirmed standards outnumber what either larger competitor discloses. Where the two scale leaders diverge from each other is jurisdiction: Cosmax’s edge is a foreign regulatory certification (US FDA OTC, plus Health Canada OTC and Indonesian Halal), while Kolmar Korea’s edge is a domestic technical one (its UV Tech Innovation Lab and CGMP designation) paired with a named client track record. None of the three discloses a company-stated MOQ or lead time in the sources reviewed, so a buyer comparing quotes should treat those figures as a live question for the sourcing call, not an assumption carried over from one manufacturer to another. Buyers weighing a broader Korean skincare mandate alongside sunscreen specifically may also want to compare this list against this site’s separate review of South Korea’s top OEM/ODM skincare factories and its private-label cosmetics partners in South Korea, since several general-skincare manufacturers overlap with, but are not identical to, the sunscreen-specific specialists profiled here.

Which one should you choose?

Choose Cosmax if your sunscreen is launching into the US market and needs a manufacturer that already operates inside the FDA’s OTC drug framework, or if the brand also wants Health Canada or Indonesian Halal market access from the same partner. Choose Kolmar Korea if the product itself is the differentiator — a novel skincare-sunscreen hybrid built on stabilisation technology the buyer wants to license into their own formula — or if working with a manufacturer that already produces for recognisable K-beauty indie brands is a meaningful reassurance for the buyer’s own due diligence. Choose Cosmecca Korea if the priority is minimising compliance and customs friction on export shipments, particularly into markets that scrutinise environmental, safety or vegan-formulation documentation, and if the buyer is comfortable working with the smallest (though still substantial) of the three by scale.

Notable exclusions

This review’s research pass for South Korea was built from scratch around the country’s genuine “big three” cosmetics ODM giants — Cosmax, Kolmar Korea and Cosmecca Korea — and all three cleared the eligibility screen with no candidates dropped for failing it. That means this list carries no padding, but it also means it does not yet cover Korea’s tier of smaller and mid-sized regional cosmetics manufacturers that also produce sunscreen under contract; those were simply outside the scope of this first research pass on the country and have not been independently verified one way or the other. For a market-scale comparison, this site’s review of OEM/ODM sunscreen manufacturers in China covers a considerably larger field, reflecting China’s bigger and more fragmented sun-care manufacturing base relative to Korea’s concentrated big-three structure. Buyers evaluating a smaller-volume or more specialised Korean sunscreen manufacturer than the three profiled here should treat that absence as a research-coverage gap, not as a judgment that no other credible options exist.

Methodology

Candidates were identified via targeted web search for Korea-based sunscreen and cosmetics ODM manufacturers, then independently verified company-by-company against each company’s own official website (cosmax.com, kolmar.co.kr, cosmecca.com) using direct site review and screenshot capture. Certification and scale claims were additionally cross-checked against independent business and trade press — PR Newswire for Cosmax’s OTC Lab and FDA/Health Canada certifications, The Korea Times for Kolmar Korea’s 2025 revenue and large-conglomerate designation, and Cosmecca’s TradeKorea company profile for its certification list. Each candidate was scored across four weighted dimensions — certification (30%), product specialisation (25%), scale and capacity (25%) and track record (20%) — with ties to be broken by earlier founding year; no tie-break was required, as all three scores were distinct. Research was captured on 26 August 2026. This review does not independently test any manufacturer’s sunscreen formulations, verify company-stated MOQ or lead-time figures (none were disclosed), or audit facilities in person.

FAQ

Which South Korean sunscreen manufacturer holds a US FDA certification in 2026?

Cosmax is the manufacturer on this list holding a US FDA OTC (over-the-counter drug) certification, obtained in 2016 through a dedicated OTC Lab. Neither Kolmar Korea nor Cosmecca Korea holds an equivalent US FDA certification as of this review’s 26 August 2026 research date, based on each company’s own disclosures and independent press coverage reviewed for this article.

Is Kolmar Korea the same company that manufactures for Beauty of Joseon in 2026?

Independent industry reporting credits Kolmar Korea with manufacturing sunscreens for Beauty of Joseon and Skin1004, two independent K-beauty brands, as of this review’s research period. This attribution comes from third-party industry sources rather than a direct statement on Kolmar Korea’s own website, and is presented here on that basis rather than as a company-confirmed fact.

Why does Cosmecca Korea rank third despite having the most certifications?

This review’s scoring weights four dimensions — certification, product specialisation, scale and capacity, and track record — not certification count alone. Cosmecca Korea scores highest on certification (28/30) but trails Cosmax and Kolmar Korea on scale-and-capacity and product-specialisation, which pulls its overall position to third among the three companies reviewed for South Korea in 2026.

Do any of these three Korean manufacturers disclose a minimum order quantity for sunscreen?

No. As of this review’s August 2026 research, none of Cosmax, Kolmar Korea or Cosmecca Korea publicly discloses a minimum order quantity or standard lead time for sunscreen contract manufacturing. Buyers should treat MOQ and lead time as questions to raise directly during a sourcing call rather than figures available from public company materials.

What does it mean that sunscreen is a “functional cosmetic” under Korean law?

In South Korea, sunscreen is classified as a functional cosmetic under the Cosmetics Act, regulated by the Ministry of Food and Drug Safety (MFDS), rather than as an ordinary cosmetic. In practice this means an SPF or PA claim is treated as a performance claim requiring supporting substantiation, which is why buyers should expect a serious Korean sunscreen OEM/ODM partner to be able to explain how it backs up the numbers on its own label.

Limitations

This review covers only South Korea’s largest, independently verifiable sunscreen OEM/ODM manufacturers as of a single research pass in August 2026; it does not include smaller or regional Korean cosmetics manufacturers that may also offer sunscreen contract manufacturing. Company-stated facility and client figures are labelled as such where independent confirmation was not available. No MOQ or lead-time data is presented for any of the three manufacturers because none was disclosed by the companies. This article does not test, certify, or independently audit any manufacturer’s product or facility.
