Market
In South Korea (KR), cod liver oil is primarily consumed as an imported dietary supplement and is commonly positioned within the MFDS-regulated health functional food framework when marketed with functional claims. Importers must comply with the Health Functional Foods Act and the imported-food control system operated by MFDS, including import declarations and border inspection steps that can delay or block customs clearance. If the product is marketed under MFDS’s functional ingredient standards for omega-3 oils (EPA and DHA-containing oils), it must meet defined manufacturing/specification requirements (e.g., EPA+DHA content, solvent residue if hexane is used, and heavy-metal limits). Labeling and advertising of functions are constrained to MFDS-recognized functions and mandatory label elements (including intake instructions and animal-source labeling where applicable).
Market RoleImport-dependent consumer market (dietary supplement / health functional food)
Risks
Regulatory Compliance HighImport declaration can be rejected in Korea if the overseas manufacturing facility is not pre-registered with MFDS under the imported-food control system, blocking customs clearance before product testing or sale.Complete MFDS overseas manufacturing facility registration well ahead of shipment and verify the registered facility details (name/address/product scope) match the import declaration.
Food Safety MediumMFDS import inspection and post-market controls can flag non-compliance with health functional food specifications relevant to fish oils marketed for functionality (e.g., EPA+DHA label conformity, heavy-metal limits, solvent residue if hexane is used, and microbiological criteria such as coliform negative).Use accredited pre-shipment testing aligned to MFDS Health Functional Food Code specifications and retain lot-linked COAs for EPA+DHA, heavy metals, solvent residue (if applicable), and microbiological tests.
Labeling And Claims MediumNon-compliant functional claims or missing mandatory label elements (e.g., health functional food emblem, intake instructions, required statement that it is not a pharmaceutical, and animal-derived ingredient source labeling) can trigger enforcement actions, relabeling requirements, or sales restrictions in Korea.Localize labels to MFDS health functional food labeling requirements and restrict functional wording to MFDS-recognized functions and approved expressions for the applicable ingredient/category.
Sustainability MediumFish oil supply chains can face sustainability scrutiny due to IUU fishing risks that undermine sustainable fisheries management and can allow non-compliant product to enter trade channels.Implement supplier traceability controls (catch documentation where applicable, vessel/flag checks, and chain-of-custody documentation) and screen for IUU risk exposure in sourcing regions.
Labor And Human Rights MediumForced labour and trafficking risks have been documented in the fisheries sector, particularly on commercial fishing vessels; reputational and buyer compliance risks can arise for fish-derived oils without robust labour due diligence.Adopt seafood labour due-diligence procedures (supplier codes, third-party audits where feasible, grievance channels, and checks on recruitment practices) and prioritize suppliers aligned with international labour standards for fishers.
Sustainability- IUU fishing risk screening and marine traceability expectations for fish-oil supply chains (including cod liver oil) given IUU’s recognized threat to marine ecosystems and its potential linkage to broader fisheries crime.
Labor & Social- Forced labour and human trafficking risks documented in parts of the global commercial fishing sector; cod liver oil supply chains sourcing from capture fisheries may require enhanced human-rights due diligence on vessel labour conditions and recruitment practices.
FAQ
What is the most common administrative reason a cod liver oil supplement shipment can be blocked at import into Korea?If the overseas manufacturing facility was not registered with MFDS before the import declaration, the import declaration can be rejected, which blocks customs clearance until the pre-registration requirement is satisfied.
If a cod liver oil product is marketed in Korea as an EPA/DHA functional health food, what daily intake range is recognized in the MFDS Health Functional Food Code?For the MFDS functional ingredient category covering omega-3 edible oils (EPA and DHA-containing oils), the MFDS Health Functional Food Code lists a daily intake amount of 0.5–2 g as the sum of EPA and DHA, alongside recognized functions related to maintaining healthy triglyceride levels and healthy blood flow.
What label elements are required for health functional foods in Korea?MFDS requires items such as the health functional food emblem, product name, business identity, expiration date and storage method, contents, nutrition and functional information, intake instructions, raw material contents, and a statement that the product is not a pharmaceutical. For animal-derived ingredients, the label must also include the type of animal source and the utilized part.
What specification checks in Korea are especially relevant for fish-oil-type functional ingredients?MFDS’s Health Functional Food Code includes specification items for omega-3 edible oils such as EPA+DHA content conformity to the label, limits for heavy metals (lead, cadmium, total mercury), a hexane solvent residue limit when hexane is used, and a coliform negative requirement.
