The GDP Framework for Transport Operators
Good Distribution Practice governs the wholesale distribution of medicinal products. It applies not just to Wholesale Dealer Licence holders but to every party in the distribution chain — including carriers who transport medicines under a Quality Agreement. If you carry pharmaceutical products, you carry GDP obligations.
Quality Agreements
Before carrying pharmaceutical products, a Quality Agreement must be in place between you and your pharmaceutical client. This agreement defines the GDP responsibilities of each party, temperature requirements, deviation reporting procedures and the scope of your qualified operations. The Quality Agreement is the foundation of your GDP compliance relationship with each client — and it will be reviewed in detail during any MHRA inspection of your client.
Temperature Control
Most GDP failures in transport relate to temperature excursions. Ambient pharmaceuticals require 15–25°C. Cold chain products require 2–8°C. Frozen products require -20°C or below. Your vehicles must be qualified to demonstrate they can maintain required temperature ranges, and your monitoring system must document pre-loading, in-transit and delivery temperatures with calibration records for all equipment.
Deviation Management
Every temperature excursion, security incident or departure from established procedures must be documented through a formal deviation system. Deviations are investigated, root causes identified, corrective actions implemented and effectiveness verified. Your MHRA inspection will examine deviation records and the quality of corrective action responses closely.
Driver Training
Drivers carrying pharmaceutical products must receive GDP training appropriate to their role — covering temperature monitoring, deviation reporting, security procedures, documentation requirements and emergency response. Training records must be maintained and available for inspection.
MHRA Inspections
The MHRA inspects Wholesale Dealer Licence holders regularly. Carrier GDP compliance is assessed as part of those inspections. Deficiencies identified at carrier level result in findings against the WDA(H) holder — which typically means your client suspends or terminates the carrier agreement until deficiencies are resolved. A robust GDP compliance system protects your client relationships as well as your regulatory standing.
