Pharma Reshoring: Building Cold Chain Lanes That Nobody’s Qualified

On January 26, 2026, Almac Group, which ships clinical trial drugs out of Durham, N.C., did something cold chain teams hate. It stopped shipping.

A winter storm had left roads in 25 North Carolina counties under snow and ice, and troopers logged 600-plus crashes in 24 hours. So Almac held every shipment for a day. Smart call from a team that's seen enough winters to know when to sit one out.

However, having that instinct takes years of watching what your lanes do in bad weather. And if you're running cold chain for one of the new plants pharma reshoring is putting up across the country, chances are you don't have that luxury. You've got a lab test on the packaging, a few trial runs from a mild month, and a sign-off that says the lane should hold. None of it has seen a real winter or summer.

The five questions below are about closing that gap before the weather does it for you. We’ll also debunk some myths in the process.

How Do You Qualify a New Pharmaceutical Shipping Lane?

You measure it with real shipments, and you don't sign off until it's survived both a summer and a winter.

In practice, that's three jobs:

• First, find out what the lane does. Map every handoff and dock where a pallet could sit, then run monitored trips, with real product or dummy loads, to see the real temperatures and wait times.
• Second, make sure your packaging and reefers can handle what you found.
• Third, prove it with real product in the worst heat and the worst cold, with a calibrated sensor like the Tive Solo Pro riding next to it.

Too many teams stop after the second step and barely test the third. They qualify the packaging in a chamber, ship a few loads during mild weather, and call the lane validated. But that's a packaging test dressed up as lane qualification.

Even USP's draft chapter on lane qualification treats the box and the lane as separate things to prove.

Why Isn't a Single Thermal Study Enough to Qualify a Lane?

Because a thermal study answers a different question. It tells you whether your box can survive a temperature pattern in a lab. While that's worth knowing, it just can't tell you what your lane will do to that box once it is on the road.

Look at the pattern many teams test against. ISTA's 7E was built from parcel shipments on 82 lanes, and its summer data came from three weeks in July 2008. Even ISTA says it isn't "customized shipping lane data." That pattern's never sat on your cross-dock or ridden with your carrier, and it missed the hottest August the Lower 48 has ever recorded by about 18 years.

Regulators have noticed, too. In a 2025 PDA survey, nearly half of respondents said they'd seen lab-only approaches rejected, and PDA's summary calls real-world data "the most credible evidence."

So use the thermal study to pick packaging, and let real shipments prove the lane. Next time someone says the box passed summer and winter testing, ask which summer. Because the answer might be July of 2008.

Does Moving Production to the U.S. Mean Requalifying Your Lanes?

Yes. 

A lane's qualification only covers the route it was proven on, so every lane out of a new plant starts from scratch. FDA's first PreCheck list alone named seven new plants in North Carolina, New York, New Jersey, and Indiana. Even an old lane that picks up a new carrier deserves a fresh look.

Don't assume domestic means easy, either. Your old import lane probably flew, since 79% of U.S. pharma imports by value come in by air, often through airports and forwarders that know pharma. The new one is a truck leaving a dock that didn't exist two years ago, through cross-docks that have never seen your product.

And not to mention, that truck will sit through things the plane never did, from August parking lots to ice like Almac's January. A carrier trying to save on diesel might even switch the reefer to cycle mode, which Tive's Smart Reefer Cycle Detection is built to catch.

How Many Shipments Does It Take to Qualify a New Lane?

About 30, spread across a full year so they catch your hottest and coldest months. That's what WHO's guidance treats as enough to trust the results, and it's 10 times what a lot of new lanes get.

The usual sign-off is three test runs, shipped in whatever month the launch happens to land in. That habit comes from drug manufacturing, which ran on "three batches and done" for years until the FDA's 2011 guidance replaced it with checking a process for as long as it runs. Your manufacturing team got that memo 15 years ago, and your lanes deserve the same treatment.

You can make each of those shipments count by putting the sensor right next to the product, in the spot most likely to run hot or cold. A logger taped to the trailer wall only tells you about the air, and auditors often ask where the logger was located during shipment.

Why is Ramp-Up the Cheapest Time to Collect Lane Data?

Because you're already shipping, and very little product is riding on the lane yet. Your engineering runs, and validation batches have to move either way, so putting a sensor in each one costs next to nothing and starts the lane record you'll need.

It's also the only time a problem is cheap to fix. If those early loads show a cross-dock that runs hot, you can still change the route, the carrier, or the packaging before launch. After launch, that same cross-dock means a deviation, an investigation, and maybe a rejected batch. This is why waiting until volume picks up to start monitoring gets it backward.

Of course, tariffs make it tempting to rush. With the 100% Section 232 tariff on patented drugs in effect since July 31, 2026 for big drugmakers and September 29, 2026 for smaller ones, there's pressure to get product moving now. So before you skip a season, use Tive's ROI calculator to weigh a single rejected pallet of biologics against a year of monitoring.

Put Your Lane's First January on the Record

Almac could sit out that storm because years of winters had demonstrated what its lanes could take. Pharma reshoring is opening lanes that haven't seen a single winter, with more than $480 billion pledged and 22 new sites in the works. Nobody knows what those lanes can take until they've carried real product through a summer and a winter, so start finding out during ramp-up, when it's less expensive.

Tive's real-time tracking is how you find out. Tuck a tracker beside the product in every ramp-up load, and you'll know the moment one starts drifting, while there's still time to save it. Just ask specialist courier Biocair, which uses Tive's real-time shipment visibility trackers to catch deviations in cell and gene therapy deliveries as they happen. The same trackers also flag a load that leaves its route or a door that opens mid-trip, both early signs of cargo theft. And if nobody on your team wants the 3:00 a.m. shift, add our 24/7 Live Monitoring service and let our team cover it.

Your new lanes will get their first January either way. Get started with Tive today and put it on the record.
