When a life-sciences shipper asks whether a carrier can run a load "to GDP," they are asking about a way of working, not a slogan on a truck. Good Distribution Practice is a quality framework for how medicinal products are stored and moved so they stay safe, identifiable and within the temperature the product requires. This essay explains what that means on a truck, in plain language. It is not a claim that Freight Network Solution Company holds a GDP certificate, and it does not invent rejection rates or market statistics.
What "GDP" refers to
In Europe, the usual written reference is the European Commission's Guidelines of 5 November 2013 on Good Distribution Practice of medicinal products for human use (2013/C 343/01). The World Health Organization also publishes GDP guidance for medicinal products. In the United States there is no single regulation that is literally titled "GDP," but life-sciences distribution is still a regulated activity, under other FDA and supply-chain rules.
We wrote a separate essay on how GDP and FDA-facing food and drug rules overlap and where they do not: GDP and FDA cold chain: where they overlap, where they don't. The short version for a transportation desk is: treat GDP as a quality system you have to be able to demonstrate (procedures, records, trained people, controlled equipment), not as a badge you display without the work behind it.
The temperature is a specification, not a guess
A GDP-style truck move starts with a written set point, not a vague "keep it cold." Common ranges, which we also describe on our GDP cold chain and cold chain pages, are:
- Chilled, often 2 to 8 °C (about 36 to 46 °F).
- Controlled room temperature (CRT), often 15 to 25 °C (about 59 to 77 °F), sometimes with a tighter set point such as 68 °F.
- Frozen, often around 0 °F / -18 °C, or a set point the shipper names.
The exact range is the shipper's and the product's, not the carrier's to invent. Confirm it in writing before the trailer is pre-cooled. A product that needs 2 to 8 °C is not close enough at 10 °C, and a CRT product can be damaged by a trailer that was pre-cooled as if it were a chilled load.
What the trucking work actually involves
Qualified, pre-cooled equipment. The trailer has to be able to hold the set point, and it should be pre-cooled to that range before the freight comes off the dock. Loading a warm trailer and hoping the unit catches up is one of the familiar ways a load gets into trouble. Our cold-chain page describes that pre-cool step as part of how we run these moves. Dock seals, a trailer that is actually at set point, and a loading process that does not leave the doors hanging open, all matter more than a paint job.
Monitoring, where the load requires it. Many life-sciences shippers require a temperature record for the trip: a data logger in the freight, a recorder on the unit, or both, and in some cases alerts that go to dispatch if the reading leaves the band. "Where equipped" and "where the shipper requires it" are the honest qualifiers. Ask for the records you need when you book, not after the truck has left.
Seals, identity and the handoff. GDP is as much about whether this is still the same product, with its history intact, as it is about temperature. Numbered, tamper-evident seals, seal numbers on the bill of lading, and a signed handoff at origin and at delivery are the ordinary tools. The receiving quality team should be able to see, at the door, that the seal matches and that the product is the product that was shipped.
Excursions, handled as events. If the temperature leaves the agreed band, or a seal is wrong, or a door problem shows up mid-route, that is a quality event, not a secret. The honest practice is to notify the shipper, protect the freight, and hand over the record. A carrier that cannot tell you what they do when something drifts is not ready for this freight.
Written procedures and trained people. GDP-style distribution expects standard operating procedures, training for the people who touch the freight, and records you can produce later. That includes the driver, the dispatcher and anyone who opens the trailer. It is paperwork with a purpose: so a later quality review can see what actually happened.
What this is not
It is not a substitute for the shipper's own quality agreement, and it is not permission to skip a product-specific instruction. It is not a claim of GDP certification, or of any other certification we have not made on the relevant page.
It is also not a promise that every FNS trailer is instrumented the same way. Temperature logging is used where the unit is equipped and where the load requires it. Your account representative can tell you what is available for a given lane.
If you have a life-sciences lane to talk through
Give us the product's temperature band, whether a logger or a data file is required, the origin and destination, the pickup and delivery windows, and any seal or chain-of-custody instructions. We run temperature-controlled work from our office in Mokena, Illinois, including chilled, CRT and frozen set points, with FNS trucks plus vetted partner carriers, and we tell you which is which.
