How to qualify a third-party cold store

Define your own requirement before you call anyone

A cold store quote only means something against a requirement you have already written down. Start with temperature class: frozen (typically minus 18C or colder), chilled (0 to 4C for most produce and protein), or a specific product band like bananas at 13 to 14C that most general-purpose facilities are not set up to hold accurately. If your product needs a narrow band, say plus or minus 1C rather than the plus or minus 3 to 4C swing a standard chill room tolerates, that alone eliminates most facilities before you tour a single one.

Throughput and pallet positions are the second variable, and exporters routinely underspec both. Pallet positions is your storage need at rest; throughput is how many pallets move in and out per week, which drives dock and labor demand independently of storage volume. A facility with 2,000 open positions but two working docks will bottleneck a harvest surge just as badly as one with too little space. Work out your peak season shape too: if 60 percent of your annual volume moves through an eight-week window, you need a facility that has handled that kind of seasonal spike before, not one whose reference customers run flat volume year-round.

Last, define handling type: full pallet in and out, case picking, cross-docking, or blast freezing before storage. Each is a different service and a different price point, and a facility quoting you a per-pallet storage rate without knowing your handling type is quoting blind. Put this requirement in writing, even a one-page brief, before you request quotes. It becomes the yardstick every proposal gets measured against.

The site visit: what to actually look at

A cold store's marketing deck will show you a clean, frost-free warehouse. Go and look at the parts they do not put in the deck. Start at the dock: check the door seals for gaps, tears, or doors that do not fully close against the trailer, since a poor seal is the single biggest source of temperature loss during loading. Ask how long a trailer typically sits at the dock and whether the dock itself is temperature-controlled or just an unconditioned buffer zone open to ambient air.

Walk the staging area, where pallets sit between receiving and put-away, or between pick and load. This is where temperature abuse actually happens, because staging areas run warmer than the storage room by design and product can sit there for hours during a busy shift. Ask to see a temperature log for the staging area specifically, not just the cold room, and what the maximum dwell time is before product must be back in controlled space.

Look at the racking and airflow pattern. Cold air needs to circulate around pallets, not just be pumped into the room; racking stacked too tightly against evaporator fans, or pallets blocking airflow channels, creates warm pockets a room-average temperature reading will not show you. Ask about defrost cycles: how often coils defrost, how long each cycle takes, and how much room temperature rises during defrost, because frequent, long defrost cycles say the refrigeration load is already near capacity.

Finally, ask about alarm response and backup power directly, and ask for the answer in specifics, not reassurance. Who gets the alarm when a room drifts out of range, what is the response time outside business hours, and is there a generator that covers refrigeration load specifically (not just lighting and security) with a tested automatic transfer switch. A facility that cannot answer this in under a minute, with a name and a number, has not actually thought it through.

Food safety certification: what each one actually covers

Certification tells you a facility has passed an audit against a defined standard, but the standards cover different things and knowing which one you need matters. A GFSI-benchmarked scheme, such as BRCGS Storage and Distribution or another GFSI-recognized standard, audits the facility's food safety management system: pest control, sanitation, temperature documentation, staff training, and traceability. This is the baseline most retailers and importing countries expect, and it is worth asking to see the actual certificate and audit scope, not just a logo on the website, since certification can be scoped to specific rooms or activities rather than the whole site.

Ask specifically what activities the certificate covers: some facilities are certified for storage but not for the value-added handling they also offer, like repacking or labeling, which needs its own scope. If your product needs HACCP-documented critical control points, such as a cold chain break point during receiving, ask to see the facility's HACCP plan for that specific point rather than taking a general food safety certificate as proof it exists.

For export product crossing into a market with its own import health requirements, check whether the facility is separately listed or approved by the destination country's competent authority where that is required, since a facility can hold strong GFSI certification and still not be on a specific market's approved list. This is a document check you can request before the site visit, and a facility that cannot produce it quickly is a signal worth weighing.

How capacity is really allocated, and what happens in peak

The rate you are quoted in the off-season tells you almost nothing about whether you will have space when you actually need it. Most third-party cold stores run mixed customer books, and when peak season hits for multiple customers at once, space gets allocated by contract terms, not by who asked first. Ask directly: do I have a committed minimum guaranteed, or am I on a spot or overflow basis that can be bumped by a customer with a standing contract.

A worked example. A packhouse contracts for 400 pallet positions year-round at a facility that also serves three other seasonal exporters whose harvests overlap with the packhouse's own six-week peak. If the contract only specifies an average monthly volume rather than a guaranteed minimum position count with a defined peak allowance, the facility can legally accommodate all four customers at their stated averages and still run out of physical space in week three of everyone's overlapping peak, because averages smooth out a spike that is real on the ground. The fix is a peak season addendum: a specific higher position count for named weeks, agreed and priced in advance, not requested as a favor when the harvest starts.

Ask how the facility has handled a genuine space crunch before, with a specific past example, not a general assurance. A facility that turned away spot business to protect contracted customers is telling you something different from one that found overflow capacity at a partner site, which quietly introduces a second facility, a second set of standards, and a second point of failure into your supply chain.

Contract terms that matter more than the headline rate

Rate structure is usually quoted as a per-pallet-position storage rate plus separate handling charges for in and out movement, and the two need to be read together, not separately, because a low storage rate paired with high handling charges can cost more than a higher storage rate with modest handling for a business with high throughput relative to average inventory held. Ask for the full rate card: storage, handling in, handling out, and any accessorial charges like case picking, re-palletizing, or labeling, since these are where quotes that look similar on the headline number diverge.

Minimum commitment and notice periods set your flexibility. A facility asking for a 12-month minimum commitment with 90 days notice to exit is a very different arrangement from a month-to-month agreement with 30 days notice, and the shorter commitment is worth paying a modest premium for if your volume is still growing or your supplier base is not yet locked in. Check what happens if you underuse the committed minimum: some contracts charge a shortfall fee against the guaranteed volume whether or not you actually stored it.

Liability caps and insurance are the terms nobody reads until there is a claim. Most warehousing contracts cap the facility's liability for lost or damaged product at a fixed value per pound or kilogram, often far below the commercial value of a temperature-sensitive food product, so the facility's own insurance will not make you whole after a real loss. Ask what the cap is, whether it can be raised for a fee, sometimes called excess valuation coverage, and separately confirm you carry your own cargo or stock-throughput insurance covering product while it sits in someone else's warehouse, since an in-transit policy usually does not.

The recovery questions nobody asks until they need them

Every cold store qualification process focuses on how product goes in and sits still. Almost nobody asks, in the same detail, how product comes back out under pressure, and that is exactly the scenario that ends up costing money. Ask what the facility's guaranteed turnaround time is from an order request to a loaded trailer leaving the dock, and ask whether that number changes during the same peak weeks you identified in your own requirement, since a facility that promises same-day pulls in the off-season may quote 48 to 72 hours during its busiest month.

Ask what documentation you get, and how fast, after a temperature excursion. If a room drifts out of range for an extended period, does the facility notify you proactively with a logged temperature record, or do you find out only if you happen to ask, or worse, only when a buyer rejects product on arrival. A facility that can produce a continuous temperature chart for any pallet, on request, within a day is operationally different from one that can only describe the room's average performance from memory.

Finally, ask about the exit itself: if you terminate the relationship, what is the process and timeline to physically remove all your inventory, and is there a fee for expedited removal. A facility with a slow, fee-laden exit process is effectively holding your inventory hostage to the relationship even after you have decided to leave, which is a real cost that a good rate on the way in does not offset.
