Frozen shrimp reefer logistics: keeping −18 °C from freezer to importer

Frozen shrimp handoffs compared

Each transfer has its own failure mode. Agree the control and the record before the first shipment.

Codex CXS 92 treats quick freezing as complete only when the product reaches −18 °C or colder at the thermal centre after stabilisation, and requires the label to state storage at −18 °C or colder. Buyers or authorities may set stricter limits.

Corridor decision matrix

One row per verified corridor. Use it to decide what to confirm with your exporter, forwarder, postharvest or food-safety adviser and the competent authorities before you commit. Seasons and evidence carry their own label.

• India → United States, China, EU, Japan

  Season

  Farmed supply; a seasonal calendar was not verified — confirm the production calendar with each exporter. Not verified — confirm

  Transport mode

  Frozen reefer container

  Temperature / specification to confirm

  Core −18 °C or colder after freezing (Codex CXS 92); the reefer set point your buyer or the importing authority requires.

  Packaging

  Inner packs and master cartons that keep their strength frozen; stated glaze level and net-weight declaration.

  Transit risk

  Power-off at terminals and transhipment; thawed edges and ice crystals; glaze or net-weight disputes.

  Handoff questions

  • Who records core temperature at the end of freezing, and how is it shared?
  • Is the reefer pre-cooled and its set point written on the booking and bill of lading?
  • Which logger file and terminal power records will reach the importer?

  Evidence: [1], [4]

• Ecuador → China, Europe, United States

  Season

  Farmed supply; a seasonal calendar was not verified — confirm with each exporter. Not verified — confirm

  Transport mode

  Frozen reefer container

  Temperature / specification to confirm

  Core −18 °C or colder (Codex CXS 92); destination record-keeping rules (for example EU Regulation 37/2005 for quick-frozen foods).

  Packaging

  Block or IQF packs, master cartons, pallet stowage that keeps return-air paths open.

  Transit risk

  Long voyages with transhipment; temperature rises during inspections; documentation gaps for the importing authority.

  Handoff questions

  • Which destination documents and establishment listings are required for this shipment?
  • How long may the container wait unplugged at each port?
  • Who attends the arrival inspection and takes probe readings?

  Evidence: [2], [4], [5]

• Vietnam → China/Hong Kong, United States, EU, Japan

  Season

  Seasonal calendar not verified; published export figures include lobster — confirm product scope. Not verified — confirm

  Transport mode

  Frozen reefer container

  Temperature / specification to confirm

  Core −18 °C or colder (Codex CXS 92); buyer specification for cooked or raw product.

  Packaging

  Retail or catering packs inside master cartons; labelling as the destination requires.

  Transit risk

  Mixed product scopes in contracts; temperature abuse at warm docks; label mismatches at the border.

  Handoff questions

  • Does the contract specify species, product form and glaze?
  • Is loading done from a sealed or temperature-controlled dock?
  • Which labelling and certificate checks happen before departure?

Temperature and monitoring rules that apply

The product reference is the Codex standard for quick-frozen shrimps or prawns. Transport and storage rules come from the destination.

• European Union: transport and storage of quick-frozen foodstuffs must use suitable recording instruments, and operators keep the records (Regulation 37/2005).
• United States: seafood processors and importers work under the seafood HACCP rule (21 CFR 123), and shippers must specify temperature conditions to carriers in writing (21 CFR Part 1 Subpart O).
• Other markets: establishment listing, health certificates and testing are set by the importing authority and are not covered here.

Glaze, packaging and stowage

Glaze protects shrimp from dehydration, but it is water, not product. Specify the glaze level and how net weight is declared, use master cartons that keep their strength in frozen storage, and stow pallets so that air can return under and around the load.

Main export corridors (dated evidence)

India reported 792,647 tonnes of frozen shrimp exports in FY2025/26, with the United States (256,128 t), China (169,505 t), the EU (135,599 t) and Japan (40,776 t) as main destinations (official MPEDA data via the Press Information Bureau, 1 June 2026). Ecuador and Vietnam are also major origins; their published figures use different product scopes, so compare them only with care.

Shelf-life risk and claims

Frozen shrimp does not usually spoil in days, but repeated temperature rises cause ice recrystallisation, drip loss and freezer burn that buyers can reject. Under the Hague-Visby Rules the carrier must make refrigerated holds fit for carriage, and written notice of loss or damage is due at delivery, or within three days if damage is not apparent. Contract terms and the applicable convention vary; take legal advice for a specific claim.

Where ColdMatch fits

ColdMatch is free for buyers. Its team reviews refrigeration and cold-chain infrastructure requests of USD 250,000 and above — for example blast or plate freezers, frozen stores, dock seals or monitoring — contacts suitable suppliers on the buyer's behalf and presents organised responses. There is no direct buyer-to-supplier contact.

RFQ checklist for frozen shrimp cold-chain projects

State each item for the facility or equipment you are procuring. Values come from you or your food-safety and engineering advisers.

• CommoditySpecies, raw or cooked, peeled or shell-on, block or IQF, glaze level.
• OriginProcessing country and site, or the receiving site if you are an importer.
• DestinationTarget markets and their temperature and record-keeping rules.
• VolumeTonnes per day frozen, storage capacity in pallet positions, peak season.
• TimingHarvest or production calendar, target commissioning date.
• PackagingInner packs, master cartons, pallet size and height.
• Temperature and spec−18 °C or colder core as a minimum, or the stricter value your buyer or authority requires; freezing time; store and dock temperatures.
• DocumentsLogger records, calibration certificates, HACCP records and the certificates your importing authority asks for.

How to request comparable quotes

1. Complete the checklist above and attach your product specification.
2. Separate freezing duty, frozen storage and dock or loading equipment in the scope.
3. Ask suppliers to state energy use only where they can document it.
4. Submit the RFQ. Requests of USD 250,000 and above are reviewed by the ColdMatch team before any supplier is contacted.

Glossary

Thermal centre

The warmest point of the product during freezing, where core temperature is measured.

Glaze

A thin layer of ice applied to frozen seafood to limit dehydration; it is not counted as net product weight.

IQF

Individually quick frozen: pieces frozen separately rather than in a block.

Reefer

A refrigerated container or trailer with its own refrigeration unit that maintains, but does not pull down, product temperature.

Pre-trip inspection (PTI)

The check of a reefer unit's operation before it is released for loading.

Freezer burn

Surface dehydration and discoloration caused by moisture loss in frozen storage.
