A pallet of insulin leaves a wholesaler’s warehouse in Brno at 4 °C and reaches a hospital pharmacy in Vienna the next morning. Under EU Good Distribution Practice, arriving cold is not enough: the wholesaler must be able to show that the product stayed within its labelled storage conditions for every hour in between, on a truck it probably does not own. That is the operational core of GDP pharmaceutical transport, and the reason pharmaceutical road freight runs on records rather than on assurances.
The rulebook is the European Commission’s Guidelines on Good Distribution Practice of medicinal products for human use (2013/C 343/01). Chapter 9 covers transportation. Chapter 4 (documentation) and chapter 7 (outsourced activities) decide how it works once a carrier is involved.
What chapter 9 of the EU GDP guidelines requires
Chapter 9 opens with a principle rather than a checklist. The supplying wholesale distributor is responsible for protecting medicines against breakage, adulteration and theft, and for keeping temperature conditions within acceptable limits during transport. Whatever the mode, it must be possible to demonstrate that the products were not exposed to conditions that could compromise their quality and integrity. Transport planning follows a risk-based approach.
The requirements that follow, in the guideline’s own terms:
- Storage conditions maintained in transit. Medicines are transported within the limits defined by the manufacturer or stated on the outer packaging. The label defines the range, not the carrier’s standard reefer setting.
- Suitable, equipped vehicles. Vehicles and equipment are suitable for their use and equipped to prevent exposure to conditions that affect product quality or packaging integrity, with written procedures for their operation, maintenance and cleaning.
- Route risk assessment. A risk assessment of delivery routes determines where temperature controls are required.
- Calibrated monitoring. Temperature monitoring equipment in vehicles or containers is maintained and calibrated at regular intervals, at least once a year.
- Deviations reported. A temperature excursion or product damage in transit is reported to the distributor and to the recipient of the affected products, and a procedure exists for investigating and handling excursions.
- Delivery into the consignee’s care. Goods go to the address on the delivery note and into the care or premises of the consignee, never left at alternative premises.
- Controlled transit storage. Where a route includes unloading, reloading or storage at a hub, temperature monitoring, cleanliness and security of that intermediate site get particular attention, and the time spent there is kept to a minimum.
None of this is optional for a licensed wholesaler, and none of it is satisfied by a carrier’s statement that the unit “was running”.
Temperature ranges, mapping and qualified vehicles
GDP sets no temperature bands of its own. The bands come from the marketing authorisation and the label, and in road freight they cluster into two lanes. Refrigerated products (most vaccines, insulins and biologics) travel at 2 to 8 °C. Products labelled for controlled room temperature travel at 15 to 25 °C, and in a Spanish August or a Polish January that band needs active heating or cooling as much as the cold lane does. Treating ambient medicines as general cargo is one of the most frequent GDP gaps in road transport.
For temperature-sensitive products, the guideline requires qualified equipment, such as thermal packaging, temperature-controlled containers or temperature-controlled vehicles, to keep conditions correct between manufacturer, wholesale distributor and customer. Where temperature-controlled vehicles are used, the monitoring equipment is maintained and calibrated, and temperature mapping is carried out under representative conditions, taking seasonal variation into account.
Mapping is where qualification becomes physical. A loaded trailer is not a uniform box: the zone near the doors warms at every stop, the area near the evaporator runs cold, and a part-loaded trailer behaves differently from a full one. Mapping finds the warm and cold spots under real load patterns, in summer and in winter, so probe placement and loading rules reflect them. Qualification then confirms that the vehicle holds its range across the route profile it will actually run, door openings included.
Wholesaler and carrier: who is responsible for what
Responsibility does not travel with the goods. Chapter 7 treats transport by a third party as an outsourced activity, and the contract giver, the wholesale distributor, remains responsible for it. Chapter 9 adds that the transport contract must encompass the chapter 7 requirements, and that the distributor must make the carrier aware of the transport conditions applicable to each consignment.
In practice that produces four obligations on the shipper side:
- A written agreement defining each party’s responsibilities: temperature range per product, monitoring and data retention, excursion notification, security and delivery rules.
- A competence assessment of the carrier before work starts, followed by periodic audits proportionate to risk.
- Control of subcontracting. The contract acceptor does not pass any of the work to a third party without the contract giver’s prior evaluation and approval. On European road freight, where loads are re-sold along a chain, this clause matters as much as the reefer unit.
- Consignment-level instructions, so driver and dispatcher know the range, the setpoint and what to do when an alarm fires.
The carrier, for its part, is bound through the contract. Its job is to run qualified equipment, follow the instructions, preserve the data and report deviations without delay. Handovers are where evidence most often breaks, which is one reason pharma shippers move to digital consignment notes that timestamp and sign every stage, as set out in the guide to eCMR vs paper CMR.
The evidence a shipper must keep
GDP is audited on records. Chapter 4 requires documentation to be retained for the period stated in national legislation, and for at least five years. For each pharmaceutical road movement, an inspector or a customer can reasonably ask for:
- The continuous temperature record of the load compartment, at the logging interval set in the procedure, from loading to delivery, with the identity and calibration status of the logger.
- Chain of custody: who loaded, which tractor and trailer, which carrier and any approved subcontractor, every handover and transit storage point, and the signed receipt at the consignee.
- Excursion records: start time, duration, peak value, the notification sent to distributor and recipient, the investigation and the quality decision on the stock.
- Vehicle evidence: qualification and mapping reports, maintenance, calibration and cleaning logs.
- The carrier file: written agreement, competence assessment and audit reports.
Handling an excursion
An excursion is not automatically a loss. The quality function compares duration and peak against the product’s stability data and decides whether the stock is released, quarantined or destroyed. That decision is only possible when the record is complete. A logger read at destination days later, with a gap where the battery failed, turns a recoverable excursion into a write-off, because nobody can prove what happened during the gap. The guideline also expects customers, on request, to receive information demonstrating that products complied with their storage conditions, so the record has to be retrievable per consignment rather than buried in a carrier’s portal.
How real-time monitoring and alerts support GDP
A logger read at destination satisfies the record requirement and little else: it tells the quality team what went wrong after the product was exposed. Real-time monitoring changes the timing. A reading drifting towards the limit triggers an alert while the truck is still on the motorway, when the driver can check the unit, the dispatcher can divert to a qualified depot, or the recipient can be warned before the pallet reaches their dock. The general mechanics of live reefer tracking are covered in the guide to cold chain trucking. For GDP the features that matter are narrower:
- Alert thresholds inside the label range, so the warning fires before the excursion rather than at it.
- Position and temperature on one timeline, so a deviation report states where it happened and for how long, not only the value.
- Unplanned stop detection, because long stops at uncontrolled sites are a common cause of excursions on multi-day routes.
- Data gaps flagged as exceptions. A silent feed is itself a deviation; how to detect one is explained in the guide to telematics data quality.
- Per-consignment export that drops straight into the excursion file and the five-year archive.
The wider argument for shipment-level tracking across a whole carrier base sits in the guide to freight visibility. On pharmaceutical lanes it is the difference between investigating an excursion and preventing one.
TrucksOnTheMap is not a GDP certification body and does not replace qualified vehicles, calibrated loggers or a quality team’s release decision. Its freight visibility software provides the live shipment records, ML-predicted ETAs and AI exception alerts that a wholesaler’s GDP procedures rely on, with data hosted in the EU under ISO 27001. Because TrucksOnTheMap works with an invite-only network of the shipper’s own carriers, the hauliers on a pharmaceutical lane are the ones the wholesaler has assessed and contracted, which is the model chapter 7 describes.
