Quick answer
Cosmax is the top-rated South Korean sheet mask contract manufacturer for private label brands in 2026, based on its US FDA and Health Canada OTC certifications, MUI halal certification, and status as South Korea’s largest cosmetics ODM by client count. Goshen Korea ranks second as a flexible one-stop ODM coordinator suited to smaller batch sizes, and Daejong Medical ranks third as a longer-running face-mask-pack specialist with a single Seoul plant. All three passed a screen requiring a verifiable South Korean registration and a live corporate website offering third-party OEM/ODM sheet mask manufacturing – only three manufacturers met that bar in this research round.
Key takeaways
- Cosmax scored 89/100, the only manufacturer in this study holding US FDA OTC, Health Canada OTC and MUI halal certification at the same time, backed by a client base of 4,500+ brands including L’Oréal.
- Goshen Korea (66/100) does not run its own factory. It coordinates sheet mask production through certified partner plants – including Kolmar and Cosmecca – which suits brands that want low-to-medium MOQ flexibility over direct-plant control.
- Daejong Medical (54/100) is the most narrowly specialised of the three, running a single Seoul plant focused on face mask packs since 2007, with no third-party certification currently listed on its own site.
- Only 3 of the candidates investigated met the eligibility screen. A fourth, SD Biotechnologies (parent of the SNP sheet mask brand), was excluded because it could not be confirmed to offer third-party OEM/ODM manufacturing rather than operating purely as a retail brand owner.
- Sourcing does not have to mean shipping from Korea. Brands in Malaysia and the wider region can manufacture the same sheet mask category closer to home – Dr Orizi produces facial and sheet masks under GMP and SA8000 standards from its Perak, Malaysia facility, trading some of Korea’s certification breadth for shorter shipping lead times and smaller minimum runs.
Who this list is for
This guide is for private label and contract-manufacturing buyers – skincare brand founders, sourcing managers and product teams – evaluating South Korea as a manufacturing base for sheet masks, hydrogel masks or facial patches, and who need to know which manufacturers actually operate certified production versus which ones coordinate it through a partner network.
Eligibility rules
To qualify, 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 sheet or tissue face masks. Companies that only distribute their own retail brand, without a confirmed third-party manufacturing service, were not eligible. Manufacturers that coordinate production through certified partner factories rather than operating their own plant remained eligible, but that distinction is disclosed in the entry rather than presented as equivalent to direct manufacturing.
Ranked entries were scored editorially out of 100 across four weighted dimensions: certification (30%), product specialisation (25%), scale and capacity (25%) and track record (20%). Research was captured on 26 August 2026 from each company’s official website and, for Cosmax’s OTC certifications, a press release distributed via PRNewswire. A minimum of three qualifying entries was required to publish; this list met that floor exactly.
At a glance
| Manufacturer | Best for | Main advantage | Main limitation | Key fact |
|---|---|---|---|---|
| 1. Cosmax | Large-scale international sheet mask programmes | Broadest certification portfolio (FDA OTC, Health Canada OTC, MUI halal) and largest client base | No public MOQ or lead-time figures – sizing suggests a larger-volume partner | Founded 1992; South Korea’s largest cosmetics ODM by client count |
| 2. Goshen Korea | Smaller, flexible private label batches | Low-to-medium MOQ flexibility and one-stop ODM coordination across several certified factories | Does not operate its own manufacturing plant – production runs through partners | Exports to 20+ countries; project portfolio spans 2013–2024 |
| 3. Daejong Medical | Straightforward face-mask-pack OEM at established scale | 19-year specialist track record in face mask pack manufacturing | No third-party certification currently listed on its official site | Manufacturing CO2 face masks since 2007; exports to 20+ countries from one Seoul plant |
The manufacturers, ranked
1. Cosmax – 89/100
Cosmax, founded in 1992 and headquartered in Seongnam-si’s Pangyo Innovation Valley, Gyeonggi-do, is South Korea’s largest cosmetics ODM by volume and client count, serving more than 4,500 domestic and international clients including L’Oréal and most major K-beauty brands. Its sheet mask, hydrogel mask and essence pad lines sit inside a broader scope that spans sunscreen and OTC sun care, cushion foundations, skincare, makeup and hair care manufacturing. According to a 2026 PRNewswire release, Cosmax became the first Korean cosmetics ODM to receive US FDA OTC certification in 2016, and separately holds Health Canada OTC certification and MUI (Indonesian halal) certification – all company-stated and independently reported by the wire release, not verified against the FDA’s or Health Canada’s own registries by this research (on how that cosmetic/OTC boundary is actually drawn during formulation, see our related piece on keeping a product classified as a cosmetic rather than a drug). Best suited for: brands running larger-volume, multi-market programmes that need OTC-grade sun care or halal-market reach alongside sheet masks. Not ideal for: early-stage brands seeking a published low-MOQ entry point – Cosmax does not publish MOQ or lead-time figures, and its scale points toward larger production runs.
2. Goshen Korea – 66/100
Goshen Korea, based in Yangcheon-gu, Seoul, positions itself as a one-stop ODM for sheet masks, hydrogel masks and patches, and states company-wide it coordinates manufacturing through partner facilities certified to ISO 22716, ISO 14001 and ISO 9001, and CGMP, providing GMP documentation, CFS certificates and REACH/SVHC compliance declarations to clients. Its named manufacturing partners include Kolmar, Cosmax, Cosmecca, ENC and CNF – meaning Goshen itself does not own the production line; it manages sourcing, formulation coordination and compliance paperwork across those certified partner plants. The company reports exporting to more than 20 countries with a project portfolio running from 2013 to 2024, and states low-to-medium MOQ flexibility, though no specific unit figure is published. Best suited for: brands that want a single point of contact managing certified third-party production and are comfortable with a coordinating ODM model rather than owning the factory relationship directly. Not ideal for: buyers who specifically require a manufacturer with its own in-house plant for direct quality-control access.
3. Daejong Medical – 54/100
Daejong Medical, located in Seongdong-gu, Seoul, has manufactured face mask packs, including CO2 face masks, since 2007 from a single plant, exporting to more than 20 countries. Its scope is narrower than Cosmax or Goshen Korea – face mask packs and facial masks specifically, rather than a broader skincare or color cosmetics range – and its official site does not currently list any third-party certification (ISO, GMP or otherwise), which this research could not independently source elsewhere. That absence is noted rather than assumed to mean no certification exists; buyers who require a specific certification should request current documentation directly. Best suited for: buyers who have already scoped a straightforward face-mask-pack product and want a manufacturer with a long, singularly focused track record in that exact category. Not ideal for: brands that need a documented certification (halal, ISO GMP, FDA OTC) as part of their own product claims, since none is currently published.
Notable exclusions
SD Biotechnologies, the company behind the globally distributed SNP sheet mask brand, was investigated as a candidate but excluded. This research could not confirm that SD Biotechnologies offers third-party OEM/ODM contract manufacturing rather than functioning purely as the owner of its own retail brand – the eligibility screen requires a confirmed third-party manufacturing service, and SD Biotechnologies did not clear that bar on the evidence available.
Methodology
Candidates were identified through general web search for South Korean sheet mask OEM/ODM manufacturers, then screened against company official websites, fetched directly and reviewed for a verifiable corporate presence and an explicit third-party manufacturing offer. Each qualifying candidate was scored editorially against four weighted dimensions – certification (30%), product specialisation (25%), scale and capacity (25%) and track record (20%) – based only on evidence published by the company itself or, for Cosmax’s OTC certifications, independently reported via a PRNewswire release. Research was captured on 26 August 2026.
What this research did not do: no factory site visits or audits were conducted; MOQ and lead-time figures were recorded only where a company published them and are labelled company-stated rather than independently verified; and certifications were verified against the companies’ own public statements, not by directly querying the FDA, Health Canada, MUI or ISO registries.
Frequently asked questions
Which South Korean company is the largest sheet mask OEM/ODM manufacturer in 2026?
Cosmax, founded in 1992 and based in Seongnam-si, Gyeonggi-do, is South Korea’s largest cosmetics ODM by client count, serving more than 4,500 domestic and international clients as of 2026. Its sheet mask and hydrogel mask manufacturing sits alongside sun care, makeup and hair care production, and it holds US FDA OTC, Health Canada OTC and MUI halal certification.
Does Goshen Korea own its own sheet mask manufacturing factory?
No. Goshen Korea, based in Seoul, operates as a coordinating ODM that manages sheet mask production through certified partner facilities, including Kolmar and Cosmecca, rather than running its own plant. It handles sourcing, formulation coordination and compliance documentation across those partner factories for its clients.
What certifications should a private label brand look for in a Korean sheet mask manufacturer in 2026?
Relevant certifications include ISO 22716 (cosmetics GMP), CGMP, and market-specific approvals such as US FDA OTC certification for sun-care or medicated claims, Health Canada OTC certification, and halal certification such as MUI for Indonesian and broader Muslim-majority markets. Cosmetics manufacturing in South Korea is regulated by the Ministry of Food and Drug Safety (MFDS), and buyers should request current certificates directly from a shortlisted manufacturer rather than relying solely on marketing claims.
Is there a minimum order quantity for sheet masks manufactured in South Korea?
MOQ varies by manufacturer and is rarely published as a fixed number. Goshen Korea states company-wide that it offers low-to-medium MOQ flexibility, while Cosmax and Daejong Medical do not publish MOQ or lead-time figures at all. Brands should request a written quotation covering MOQ, lead time and per-unit cost before committing, since none of these figures should be treated as universal across a manufacturer’s full product range.
Can a Malaysian or Southeast Asian brand manufacture sheet masks closer to home instead of sourcing from South Korea?
Yes. Sheet mask manufacturing is not exclusive to South Korea – Malaysian OEM manufacturers, including Dr Orizi in Perak, produce facial and sheet masks under GMP and SA8000 certification. For brands prioritising shorter shipping lead times, smaller minimum runs, or halal certification within ASEAN, a regional manufacturer can be a practical alternative or complement to sourcing from Korea, depending on the certification profile the brand specifically needs.

Limitations
This research round identified only three manufacturers meeting the eligibility screen; a wider or differently worded search may surface additional qualifying candidates in future updates. MOQ and lead-time figures are undisclosed for two of the three manufacturers and company-stated (not independently verified) for the third. Certification claims were checked against each company’s own site and, for Cosmax, one independently published press release – not against the FDA, Health Canada, MUI or ISO registries directly. Goshen Korea’s partner-facility certifications were not independently verified beyond Goshen’s own claims.
Update history
1 September 2026 – First published. Based on research captured 26 August 2026. This list will be revisited if certification status changes at any listed manufacturer or if new eligible candidates are identified.
Sourcing sheet masks closer to home
South Korea’s sheet mask sector is deep and certification-rich, from Cosmax’s FDA-and-halal-certified scale down to single-plant specialists like Daejong Medical – and for brands building a multi-market, certification-heavy sun care or skincare range, that depth is hard to match. But not every sheet mask programme needs to ship from Korea. Dr Orizi manufactures facial masks, sheet masks, silk masks, sleeping masks and clay masks from its GMP and SA8000-certified facility in Perak, Malaysia, and sister company ORIZI Group runs a dedicated face mask OEM line spanning sheet, clay, wash-off, sleeping, peel-off and modelling formats with ISO 22716 and halal capability. For brands prioritising shorter regional shipping times, smaller minimum runs, or halal certification for ASEAN markets, a Malaysian manufacturer is worth quoting alongside a Korean one – the right choice depends on which certifications and volumes the brand actually needs, not on which country sounds more established in skincare.
