Key Takeaways
- GDP (Good Distribution Practice) governs how medicinal products are stored, transported, and handed off after manufacturing, ensuring that identity, quality, and integrity are maintained all the way to the receiving facility.
- Most temperature excursions happen at transitions, not during the transport leg itself: loading docks, customs holds, courier transfers, and warehouse intake.
- Each handover, from manufacturer to freight forwarder to last-mile delivery, carries its own documentation and equipment qualification requirements.
- Continuous pharmaceutical cold chain monitoring, reviewed at every handover, is expected in GDP.
- SCGJWD’s value as a logistics partner in pharmaceutical cold chain management is evident in documented procedures and chain-of-custody records, aside from well-maintained temperature-controlled storage and transportation.

- Frequently Asked Questions About Pharmaceutical Cold Chain Management
A vaccine shipment may go through several hands from the manufacturer’s loading dock to the hospital pharmacy shelf, with each transfer posing a risk of temperature control failure. For pharmaceutical manufacturers, distributors, and importers, what GDP (Good Distribution Practice) requires at each transition matters more than the transport route itself. Partnering with a provider experienced incold chain management provides businesses with a starting point for consistently meeting those requirements throughout the entire chain.
What is Good Distribution Practice (GDP) in Pharmaceutical Logistics?
GDP is the set of quality standards governing the storage, transport, and distribution of medicinal products after they leave the manufacturer, ensuring that product identity, quality, and integrity are maintained throughout the supply chain.
In Thailand, the Thai Food and Drug Administration (Thai FDA), operating under the Ministry of Public Health, sets and regulates Good Distribution Practices (GDP) for medicinal and healthcare products. In the EU, GDP is set out in Guidelines 2013/C 343/01 under Directive 2001/83/EC. The World Health Organization publishes parallel international guidance, and national regulators, including the US FDA, maintain their own requirements that may reference or align with these frameworks. Exact requirements differ by destination market, so route- and market-specific verification is necessary.
What Good Distribution Practice (GDP) Covers
GDP is not limited to temperature control. It covers facility and vehicle qualification, temperature mapping, personnel training, documentation and traceability, deviation and complaint handling, and the designation of a responsible person at each licensed distributor. It also works as a chain-of-custody standard, applying to whoever holds the product at any given moment, from the manufacturer's dock through the last courier who hands it to the receiving pharmacist.
In Thailand and across the region, third-party logistics companies also manage long-term cold-chain holding environments that follow GSDP (Good Storage and Distribution Practices) and include quality management systems, qualified premises and equipment, and controls that protect product integrity from storage through distribution. SCGJWD, through its subsidiary Pacific Cold Storage, holds BSI certification under CODEX GSDP: 2003 (Certificate No. GSDP 815837, valid through October 2027) for controlled room temperature (15–25°C) pharmaceutical storage management, reflecting the facility and process qualification requirements of GDP at each handover.
What Temperature-Controlled Logistics Means in the Pharmaceutical Industry
Temperature-controlled logistics in the pharmaceutical industry means transport and storage held within a validated range specific to the product, using qualified vehicles, packaging, or facilities, verified through continuous monitoring rather than one-time checks. Products fall into different categories, such as deep-frozen at -70°C, frozen at -20°C, refrigerated at 2°C to 8°C, and controlled room temperature at 15°C to 25°C. The applicable range depends on the manufacturer’s specifications and stability data.
Why Handover Points Are Where Cold Chains Actually Fail
Most temperature excursions occur during transitions, not during the transport leg itself. Loading dock delays, customs holds, last-mile transfers to a courier, or a warehouse receiving area without pre-cooled staging create more risk than a well-maintained reefer truck on a highway. This is why GDP puts so much weight on documentation and monitoring at handover points more than on vehicle specifications alone.
GDP Requirements at Every Handover Point
Handover 1: Manufacturer to Freight Forwarder
Typically, the manufacturer’s or distributor’s responsibility: qualified packaging matched to the validated range, a current Certificate of Analysis, and confirmation from the freight forwarder or transport carrier that the outbound vehicle or container has been temperature-mapped for the route.
Handover 2: Freight Forwarder to Carrier (Air, Sea, or Road)
Needs continuous data logger activation before departure, confirmation the carrier’s equipment (reefer container, air ULD, or refrigerated vehicle) matches the required range, and a documented record with timestamp and reading at transfer. Time pressure on airport ramps or port terminals is a common failure point if not coordinated in advance.
Handover 3: Customs Clearance and Border Crossing
Pre-cleared documentation minimizes dwell time and, where regulations allow, temperature-controlled holding areas at the border protect shipments delayed during inspection. Customs delays sit outside the carrier’s direct control, which is why GDP emphasizes risk management and continuous monitoring.
Handover 4: Last-Mile Delivery to the Receiving Facility
Requires a suitable vehicle or insulated packaging designed for the shorter transit period, along with a procedure to record the arrival temperature right before unloading. This leg is often handled by a different party than the main-leg carrier, which is exactly the chain-of-custody transfer for which GDP requires thorough documentation.
Handover 5: Receiving Facility and Warehouse Intake
Requires pre-cooled or pre-warmed staging matched to the product’s range, immediate transfer to qualified storage, and reconciliation of the pharmaceutical cold chain monitoring data against accepted tolerances before acceptance into inventory.
How Is Pharmaceutical Cold Chain Monitoring Done During Transport?
Typically, through continuous electronic data loggers that record temperature, and sometimes humidity, at set intervals. Single-use and reusable loggers get placed near the product itself, not just against the container wall, since wall temperature does not always reflect actual product condition, and data gets reviewed at every handover.
Connected devices add real-time tracking and alerting, transmitting temperature data during transit and flagging excursions as they happen. SCGJWD’s approved digital freight capabilities, including real-time tracking and integrated communication tools, support this visibility across a shipment’s route. Either way, GDP expects monitoring data reviewed against the approved range at each handover, with any excursion investigated and documented.
Common Cold Chain Deviations and How GDP Addresses Them
- Dock delays leave product on an unshaded loading area.
- Equipment failure mid-transit, such as a reefer malfunction or power interruption.
- Incomplete or missing handover documentation leaves it unclear which party held the product when a deviation occurred.
- Ambient staging at warehouse intake while paperwork is processed instead of moving straight into qualified storage.
GDP mandates a documented deviation and investigation procedure for each of these cases. The aim is not to stop every potential deviation, as equipment may fail despite careful planning.
A Practical GDP Handover Checklist
- Confirm the product’s validated temperature range and required monitoring method before booking transport.
- Verify equipment qualification, whether vehicle, container, or packaging, matches that range for every leg.
- Require a documented temperature reading and timestamp at every handover, not only at origin and destination.
- Confirm customs and border procedures for temperature-controlled holding where logistic delays are possible.
- Review pharmaceutical cold chain monitoring data against approved tolerances promptly after each leg.
- Maintain a documented deviation and investigation process for any excursion.
Choosing a Logistics Partner for Pharmaceutical Cold Chain Management
For pharma manufacturers, distributors, and importers, choosing a logistics partner comes down to whether the current setup meets GDP expectations from end to end. Seek documented handling protocols at every handover, vehicles and facilities with temperature mapping suited to the product range, ongoing monitoring instead of occasional checks, and transparent chain-of-custody records for all parties involved, including subcontracted last-mile carriers.
