Seafood export cold chain — freezing, storage and logistics guide
Export-grade seafood is won or lost in the first hours after landing and in the freezing tunnel. This guide sets out how to specify chilling, blast freezing and IQF, frozen storage and reefer logistics for an export facility — and how ColdMatch Group prepares a supplier-ready RFQ around it. Aquaculture production itself sits with our sister platform, FishMatch Group.
The four cold chain stages of a seafood export project
1. Landing, chilling and pre-processing
Flake or slurry ice capacity, chilled holding at 0 to +2 °C and hygienic processing rooms sized for peak landings, not average volumes. Undersized chilling at this stage is the most common cause of export rejections.
2. Blast freezing and IQF
Freezing capacity is specified in tonnes per 24 hours at a defined core temperature (typically −18 °C core from +5 °C inlet). Tunnel, spiral or plate freezers are chosen by product form: whole fish, fillets, shrimp, cephalopods or value-added packs.
3. Frozen storage and glazing
−18 to −25 °C export stores for standard whitefish and shrimp; −35 to −60 °C for tuna and sashimi-grade products. Glazing lines, re-freezing capacity, humidity control and racking density define usable pallet positions.
4. Export logistics interface
Reefer loading docks with dock shelters, staging at product temperature, container pre-cooling, temperature logging and traceability records demanded by EU, US FDA, Japanese and Gulf importers.
What suppliers must quote against
| Freezing capacity | Tonnes / 24 h at defined inlet and core temperature, per product form |
|---|---|
| Storage temperature | −18 to −25 °C standard export; −35 to −60 °C tuna and premium sashimi grades |
| Storage volume | Pallet positions plus 15–20 % seasonal peak buffer |
| Refrigerant | Ammonia (R717) for large plants; CO₂ cascade where ammonia charge is restricted |
| Redundancy | N+1 compressors for export plants; standby generator sized for full freezing load |
| Monitoring | Continuous logging, alarms and audit-ready reports for HACCP, EU approval numbers and importer audits |
| Hygiene | Washdown-rated panels, coved floors, drainage and materials compatible with seafood processing |

There is no direct buyer-to-supplier connection: every RFQ comes to the ColdMatch team, which validates it, contacts suitable suppliers on the buyer's behalf and presents organized responses through ColdMatch.
