GDP checklist for pharmaceutical ocean imports

Good Distribution Practice (GDP) compliance starts at origin: validated reefer equipment, calibrated data loggers, and documented handoffs. A single unlogged excursion between the warehouse dock and the container door can be enough to put an entire batch's regulatory status in question, regardless of how well the ocean leg itself was managed.

GDP exists to make sure a pharmaceutical product's quality, identity, and efficacy are preserved from the moment it leaves the manufacturing site to the moment it reaches the end customer, not just while it's at sea. That means the pre-shipment checklist has to cover the warehouse, the drayage leg to the port, and the terminal dwell time, not only the vessel voyage.

Reefer equipment validation comes first: the container should have a current calibration certificate, a pre-trip inspection (PTI) record confirming it's holding the required 2–8°C (or product-specific) range before loading, and a documented genset or power source plan for any period the container spends off a powered chassis at the terminal.

Data loggers need to be placed according to a documented protocol, typically at the warmest and coolest points inside the load and not just wherever is convenient, and calibrated against a traceable standard within the manufacturer's recommended interval. A logger that's simply present but undocumented as calibrated doesn't hold up to a customer or regulator audit.

The paper trail matters as much as the equipment: a complete GDP shipment file includes the PTI report, temperature logger data covering the full door-to-door journey, a chain-of-custody record showing every handoff (warehouse to drayage, drayage to terminal, terminal to vessel, and the reverse at destination), and any temperature excursion reports with root-cause notes if a deviation did occur.

On the customs side, pharmaceutical imports into the US typically require FDA prior notice in addition to standard entry documentation, and the entry should be pre-filed early enough that customs review doesn't become the reason a temperature-sensitive container sits at the terminal longer than planned.

At the destination port, the handoff itself is a common weak point: confirm in advance that the trucker picking up the container has a working reefer unit and a driver briefed on the temperature range, and that the delivery appointment doesn't leave a loaded reefer sitting unplugged in a yard queue.
