South Korea's sunscreen export business is bigger than most brand owners realise, and it runs through a small number of dedicated OTC/sun-care production groups rather than a crowded field of generalists. Korean sun care is regulated as a "functional cosmetic" domestically, exported at scale to the US, Canada and Southeast Asia, and increasingly built by the same handful of ODM groups that also supply the world's biggest skincare labels. This guide profiles the three Korean manufacturers with the deepest, most independently verifiable dedicated sun-care manufacturing record.

Quick answer: who makes sunscreen on contract in South Korea?
Three manufacturers meet the bar for a dedicated, independently verifiable South Korean sunscreen and sun-care OEM/ODM operation: Cosmax, which runs a standalone OTC Lab and was the first Korean cosmetics ODM to hold US FDA OTC certification; Kolmar Korea, which developed the world's first hybrid composite sunscreen stabilisation technology and reportedly manufactures sun care for brands including Beauty of Joseon and Skin1004; and Cosmecca Korea, the smaller of the three by scale but the deepest on paper for certifications, with seven current credentials including ISO 22716 and a Vegan Cosmetics certification. All three also produce skincare, makeup and other categories — sunscreen is one line within a broader ODM business, not a standalone factory.
Key takeaways
- Korea's sun-care ODM market is concentrated, not fragmented. Rather than dozens of mid-size sunscreen specialists, the credible, verifiable dedicated-capacity field narrows quickly to a small group of large, multi-category ODMs with a documented sun-care line.
- Certification breadth and manufacturing scale do not move together. Cosmecca Korea holds the widest certificate stack of the three (seven credentials, including AEO and Vegan Cosmetics) but is the smallest by disclosed scale and revenue — a reminder to check certifications and capacity separately rather than assuming one implies the other.
- None of the three publishes a public MOQ or lead time for sunscreen. All three list MOQ and lead time as company-stated information only available on direct enquiry — a contrast with some Southeast Asian factories that publish unit floors on their own websites.
- US and Canadian OTC certification is a genuine differentiator. Cosmax is the only one of the three independently confirmed to hold both US FDA OTC and Health Canada OTC certification, relevant for any brand planning to sell sunscreen (an OTC drug category in the US) rather than a cosmetic SPF product.
- Korea's own sunscreen rules run through the Ministry of Food and Drug Safety (MFDS), not a cosmetics-only body. Sunscreen is classified as a "functional cosmetic" domestically, which affects what an SPF/PA claim requires before a Korean-made product can carry it, in Korea or on export paperwork referencing Korean manufacture.
Who this list is for, and how we chose
This guide is written for a brand owner evaluating South Korea as a sourcing base for sunscreen or SPF-labelled skincare specifically — not general Korean skincare sourcing, which we cover separately in our wider guide to Korean cosmetic OEM/ODM manufacturers.
We applied four screening rules before researching or writing a single entry:
- Operating manufacturer with a verifiable corporate registration. Trading companies, brokers and sourcing agents were excluded.
- A live, independently verifiable South Korean corporate website. Each site was loaded directly and checked against independent press or B2B-directory reporting, not taken solely on the company's own claims.
- Third-party OEM/ODM contract manufacturing must be an offered service — not an own-brand-only cosmetics house.
- Sun care must be a documented, named product line, not an inferred capability.
Ranking within the list reflects a weighted assessment across four dimensions: certification breadth and independence of evidence (30%), sun-care product specialisation (25%), disclosed scale and production capacity (25%), and track record/company history (20%). Listed in that ranked order — OEMHallmark does not sell ranking positions; see our methodology for the full framework.
The list at a glance
| Company | Best for | Main advantage | Main limitation | Key fact |
|---|---|---|---|---|
| Cosmax | Brands needing FDA/Health Canada-compliant OTC sun care at global scale | First Korean ODM with US FDA OTC certification | No public MOQ or lead-time figures | Develops and produces for 18 of the world's top 20 beauty companies |
| Kolmar Korea | Brands wanting proprietary UV/hybrid sun-care technology | World-first hybrid composite sunscreen stabilisation technology | Broad ODM generalist; sun care is one of nine R&D divisions, not the sole focus | 2025 consolidated revenue of 2.72 trillion KRW; first Korean cosmetics ODM named a large business group |
| Cosmecca Korea | Brands prioritising certification breadth over sheer scale | Deepest certification stack of the three (7 credentials, incl. AEO and Vegan Cosmetics) | Smallest of the three on disclosed scale; founding year inconsistently reported | Korea's third-largest cosmetics ODM by market share; pioneered domestic BB cream production |
What Korea's MFDS expects of a sunscreen manufacturer
South Korea's cosmetics and drug regulator is the Ministry of Food and Drug Safety (MFDS). Domestically, sunscreen sits inside Korea's "functional cosmetics" category alongside whitening and anti-wrinkle products — a tier that requires supporting efficacy and safety data before a product can carry an SPF/PA claim, rather than the simpler general-cosmetic notification used for a plain moisturiser. For a brand sourcing Korean-made sunscreen for export, this matters in two practical ways: it is part of why established sun-care ODMs with in-house testing infrastructure (all three companies here) are the safer route into the category, and it means SPF/PA substantiation data usually needs to be requested and reviewed as part of due diligence, not assumed to transfer automatically from the factory's domestic filing to a destination market's own rules (the US OTC monograph and the EU/UK cosmetic SPF testing regime are both separate systems). Brands new to the category may find our explainer on cosmetic product safety reports useful background before requesting documentation from any of the three manufacturers below.
1. Cosmax
HQ: Seongnam-si, Gyeonggi-do · Founded: 1992 · Type: Full-range cosmetics ODM with a dedicated OTC/sun-care lab
Cosmax is the largest cosmetics ODM in South Korea by client count and output, developing and producing for more than 4,500 brands worldwide, including 18 of the world's top 20 beauty companies. Its sun-care credentials stand apart from the other two: Cosmax established a dedicated OTC Lab covering the full research-to-manufacturing process for the US sun-care market, and in 2016 became the first Korean cosmetics ODM to receive US FDA OTC certification, later adding Health Canada OTC certification and Indonesia's MUI Halal certification. That combination is directly relevant to any brand planning to sell sunscreen as an over-the-counter drug product in North America rather than as a cosmetic SPF item, since OTC monograph compliance is a different regulatory track from cosmetic registration. Cosmax runs facilities across Korea, China, the USA, Indonesia and Thailand, giving it production flexibility that neither of the other two companies discloses. Neither MOQ nor lead time is published; both are described as available on direct enquiry.
2. Kolmar Korea
HQ: Sejong (R&D Complex in Seoul) · Founded: 1990 · Type: R&D-led cosmetics and health ODM, first mover in the Korean model
Kolmar Korea effectively created the modern Korean cosmetics ODM industry and holds Korea's first and second CGMP-conforming company designations. Its sun-care specific claim to fame is its UV Tech Innovation Lab, which developed what the company describes as the world's first hybrid composite sunscreen stabilisation technology, and independent industry reporting links Kolmar Korea to sunscreen manufacturing for well-known indie K-beauty brands including Beauty of Joseon and Skin1004. Kolmar Korea runs three plants, employs more than 1,300 people, and reported 2.72 trillion KRW in consolidated 2025 revenue — strong enough that in 2026 it became the first Korean cosmetics ODM formally designated a large business group by the country's Fair Trade Commission framework. The trade-off against Cosmax is focus: sun care is one of nine specialised R&D divisions at Kolmar (alongside skincare, makeup, personal care, natural products, biome science and more), so brands should confirm current sun-care-specific capacity and lead time directly rather than assuming dedicated OTC-scale production equivalent to Cosmax's standalone lab.
3. Cosmecca Korea
HQ: Eumseong-gun, Chungcheongbuk-do · Founded: circa 1990 (a B2B directory profile states 1990; an industry summary implies 1999 — recorded here as unconfirmed rather than guessed) · Type: Full-range cosmetics ODM, Korea's third-largest by market share
Cosmecca Korea is smaller than Cosmax or Kolmar Korea on every disclosed scale measure, but it carries the deepest certification stack of the three: ISO 45001, OHSAS 18001, ISO 14001, ISO 9001, ISO 22716 (cosmetic GMP), AEO (Authorized Economic Operator) status, and a Vegan Cosmetics certification — seven current credentials against Cosmax's three and Kolmar's one publicly listed. Cosmecca states it pioneered BB cream production in Korea and lists sun care and skincare among its core lines alongside men's skincare, colour cosmetics, bath and body, fragrance and hair care, exporting to China, Thailand, Vietnam, Japan, Taiwan, Hong Kong and the United States. For a brand that weighs a documented compliance and quality-management paper trail more heavily than raw production scale, Cosmecca is the strongest case of the three; for a brand that needs Cosmax- or Kolmar-scale volume or Cosmax's specific US/Canada OTC drug certification, it is the weaker fit. As with the other two, MOQ and lead time are not published and must be requested directly.
Notable exclusions: who else we looked at
This research pass was built specifically around dedicated, independently verifiable sun-care manufacturing evidence — a narrower screen than a general Korean cosmetics ODM search. Unlike some of the country lists in this series, it did not surface a fourth or fifth genuinely eligible dedicated sun-care candidate to exclude for a documented reason (an expired domain, an unresolved certification claim, and so on): the field of Korean ODMs with an independently confirmed, named sun-care manufacturing line and verifiable scale narrows quickly to these three. Our broader general Korean cosmetics OEM/ODM guide lists additional large ODMs — including C&C International, Cosvision, Intercos Korea and Kolmar BNH — that may also manufacture sunscreen among a wider skincare and makeup catalogue; they are not repeated here because this list required documented sun-care specialisation specifically, which we were not able to independently verify for those companies at the same evidentiary standard applied to the three above.
Methodology and limitations
Candidates were identified through targeted search for Korean sunscreen and cosmetics ODM manufacturers, cross-checked against each company's official website and independent industry or business-press reporting (PR Newswire on Cosmax's OTC Lab and FDA certification, The Korea Times on Kolmar Korea's 2025 revenue and conglomerate designation, and a TradeKorea B2B directory profile for Cosmecca Korea's certifications and founding-year data). Research was captured on 26 August 2026.
What we did not do matters as much as what we did: we did not visit any factory, audit any quality system, independently verify certificates against the issuing bodies, test any sunscreen product, or contact any company for comment. Every certification, capacity figure and founding date above is reproduced as the company or an independent source states it, and is labelled accordingly. MOQ and lead time were not published by any of the three and are not estimated here — treat them as request-only figures until confirmed in a quotation. Cosmecca Korea's founding year is disclosed inconsistently between the two sources available to us and is recorded as unconfirmed rather than resolved by guesswork.
Frequently asked questions
Who is the largest sunscreen OEM manufacturer in South Korea in 2026?
Cosmax is the largest of the three verified dedicated sun-care manufacturers profiled here, and generally regarded as the largest cosmetics ODM in South Korea overall by client count and production volume. Its standalone OTC Lab and 2016 US FDA OTC certification — the first for a Korean cosmetics ODM — are specific to sun-care and OTC drug-category manufacturing rather than general skincare scale.
What certifications should a South Korean sunscreen contract manufacturer hold?
At minimum, look for ISO 22716 (cosmetic good manufacturing practice) and, for the US or Canadian market specifically, FDA OTC or Health Canada OTC certification, since sunscreen is regulated as a drug product in both countries. Cosmecca Korea holds the broadest documented stack among the three profiled here (ISO 45001, OHSAS 18001, ISO 14001, ISO 9001, ISO 22716, AEO and Vegan Cosmetics), while Cosmax is the only one of the three independently confirmed to hold both US and Canadian OTC certification. Domestically, Korea's Ministry of Food and Drug Safety (MFDS) governs functional-cosmetic filings for SPF/PA claims.
Can a small or first-time brand order sunscreen from these Korean manufacturers?
Possibly, but none of the three publishes a public minimum order quantity or lead time for sun care as of this research (26 August 2026) — all three describe those terms as available on direct enquiry. That is a real contrast with some Southeast Asian sunscreen factories that publish unit-count MOQs on their own websites, so a first-time or small-batch brand should budget extra time to request and negotiate terms directly rather than assuming a low-MOQ entry point — see our explainer on what MOQ, lead time and turnkey actually mean for how to read a Korean ODM's quotation.
What is the practical difference between Cosmax, Kolmar Korea and Cosmecca Korea for sunscreen sourcing?
Cosmax offers the widest regulatory reach for OTC-classified sunscreen (US and Canada) plus the largest production footprint. Kolmar Korea offers proprietary hybrid sun-care stabilisation technology and a track record with well-known indie K-beauty sun-care brands, inside a broader nine-division R&D structure. Cosmecca Korea offers the deepest certification paper trail of the three but the smallest disclosed scale, making it a fit for brands weighting documented quality-management evidence over volume.
Do Korean sunscreen manufacturers need MFDS approval before a product can carry an SPF claim?
Sunscreen falls inside Korea's "functional cosmetics" category, which the Ministry of Food and Drug Safety (MFDS) regulates more closely than a general cosmetic, given the SPF/PA efficacy claim involved. This is a domestic Korean filing requirement and is separate from what a destination export market requires — a US-bound sunscreen still needs to satisfy the FDA's OTC monograph, and an EU/UK-bound one needs its own cosmetic SPF testing, regardless of Korean domestic status. Brands should request both the Korean functional-cosmetic documentation and any destination-market-specific data from their chosen manufacturer.
