Frozen scad (Carangidae; commonly traded under scad/jack mackerel group species) is a frozen wild-caught fish product consumed in South Korea via a mix of domestic landings and imports. Scientific literature documents Japanese jack mackerel (Trachurus japonicus) in Korean waters around Jeju Island and the Southern Sea, supporting a local supply base that can be complemented by imported frozen product. As an imported fishery product, market access is governed by MFDS imported food safety controls (including foreign facility registration and import inspection) and Korea Customs Service customs clearance through UNI-PASS with standard shipping/origin documentation. The most trade-disruptive compliance risk for scad-group fish is histamine formation under time–temperature abuse, making strict cold-chain control central to safe and compliant supply.
Market RoleImport-dependent consumer market with supplemental domestic landings
Domestic RoleDomestic seafood consumption item supplied by domestic capture fisheries and imported frozen fishery products
SeasonalityFrozen market availability is generally year-round due to freezing and imports; biological seasonality for Trachurus japonicus in Jeju-area waters shows a spring–summer spawning period.
Specification
Primary VarietyDecapterus maruadsi (Scad; Japanese scad)
Secondary Variety- Trachurus japonicus (Japanese scad / jack mackerel)
Physical Attributes- Whole-round frozen presentation is common for scad-group fish; buyer acceptance typically emphasizes absence of excessive freezer burn and physical damage.
Packaging- Shipping cartons should be lot-coded to support traceability and recall readiness.
- Protective glazing may be used on frozen fish to protect quality during extended frozen storage (ensure declared net weight is not misleading for the market).
Supply Chain
Value Chain- Wild capture landing (domestic) or overseas catch → chilling → freezing → frozen storage → sea freight (reefer) → MFDS import inspection → Korea Customs Service customs clearance (UNI-PASS) → domestic frozen distribution → retail/foodservice
Temperature- Maintain frozen storage and distribution at -18°C or lower as a referenced benchmark in Codex fish/fishery product handling guidance.

Risks
Food Safety HighHistamine formation risk can block entry or trigger enforcement actions if time–temperature control fails for histamine-susceptible fish groups; scad/jacks (Carangidae) are included among histamine-risk fish families in official risk communications, making frozen cold-chain control critical for Korean imports.Require HACCP controls and temperature loggers from catch through freezing and distribution; implement supplier histamine monitoring/verification and reject lots with temperature abuse indicators.
Regulatory Compliance HighMFDS requires foreign food facility registration before import declaration for imported foods including fishery products; missing or incorrect registration can result in import declaration rejection or import suspension actions tied to the facility.Confirm MFDS foreign facility registration status and product scope before contracting; align exporter documents (facility name/address/product) with the importer’s declaration data.
Logistics MediumFrozen scad is cold-chain dependent; reefer delays, temperature excursions, or extended dwell times can degrade quality and increase food-safety risk, while freight volatility can materially shift landed costs for low-to-mid value frozen whole fish.Pre-book reefer capacity in peak seasons, use end-to-end temperature monitoring, and build contingency lead time for inspection/holds at entry.
Labeling MediumCountry-of-origin and food labeling non-compliance can lead to clearance delays, relabeling costs, or rejection; scad-group naming ambiguity increases the risk of species mislabeling.Standardize Korean label content and origin marking with the importer; include scientific name in internal specs and verify labeling against MFDS and origin-labeling guidance before shipment.
Sustainability- IUU (illegal, unreported, and unregulated) fishing exposure screening for wild-caught supply chains
- Stock sustainability expectations for small pelagic fisheries supplying frozen whole fish markets
Standards- HACCP-based controls for fish and fishery products
- ISO 22000 / FSSC 22000 (buyer-driven)
FAQ
What must be completed before importing frozen scad into South Korea?Before the import declaration is filed, the foreign food facility exporting the product must be registered with the Ministry of Food and Drug Safety (MFDS), and the shipment will enter MFDS’s imported food inspection workflow at the border. If the required pre-registration is not completed, the import declaration can be rejected or trade can be suspended for the facility.
Which documents are commonly required for customs clearance in Korea for imported frozen fish?Korea Customs Service guidance lists an import declaration plus common supporting documents such as the commercial invoice, packing list, bill of lading, certificate of origin, and certificates of inspection/quarantine as applicable to the consignment.
Why is histamine a key risk to manage for frozen scad shipments into Korea?Scad-group fish are within histamine-susceptible fish families referenced in official risk communications, and histamine can form when fish are temperature-abused. Managing this risk requires strict time–temperature control (including maintaining frozen conditions through storage and transport) and HACCP-based controls with verification testing when needed.
