Cold-chain shipping of biologics from India

Biologics such as monoclonal antibodies, insulins, enzyme therapies and vaccines are usually time- and temperature-sensitive. The World Health Organization (WHO) calls them time- and temperature-sensitive pharmaceutical products and defines a temperature excursion as any exposure outside the ranges prescribed for storage or transport, ranges that the manufacturer sets from stability data. Moving them from India to a hospital or licensed importer abroad means keeping that range intact across several handovers: the exporter's cold room, export clearance, one or more flights, a transit hub, destination customs and the receiver's store.

This guide explains how packaging, monitoring and lane planning fit together, and what a buyer can ask before goods leave. It describes general practice under WHO, IATA and EU guidance. The product's own labelling and the manufacturer's instructions always take precedence.

Start from the product's stability profile

The labelled storage range is the fixed point. WHO's model guidance for time- and temperature-sensitive products (TRS 961, Annex 9) says product stability data must show the acceptable excursion time during transport, and that transport temperatures should not harm product quality. Storage and transport ranges can differ, so check both before choosing packaging.

WHO's packing rules ask shippers to protect freeze-sensitive products against temperatures below 0°C when frozen packs are used, and the EU good distribution practice guidelines say cool packs in insulated boxes should not be in direct contact with the medicine.

Passive or active packaging

WHO defines passive systems as insulated enclosures that hold temperature with a finite amount of pre-conditioned coolant, such as chilled or frozen gel packs, phase change materials or dry ice. Active systems are powered and thermostatically controlled, for example refrigerated air cargo containers.

Passive shippers

A passive shipper is only as good as its qualification. Under section 6.8.3 of the WHO guidance, qualification should record the full packaging assembly, the conditioning regime, the minimum and maximum payload and the placement of monitors. It should also cover the expected ambient profile from departure to arrival in the recipient's temperature-controlled store. WHO's technical supplement on qualifying shipping containers describes testing against both heat and cold profiles, each with maximum and minimum loads.

The result is a validated duration, usually stated in hours. The country import guides on this site suggest passive shippers qualified for at least 72 hours on short direct lanes such as the United Kingdom, and 120 hours or more where freight connects through hubs, as for Brazil, which has no direct passenger flights from India.

Active containers

Active containers suit larger air cargo lots and longer routings because they do not depend on a fixed amount of coolant. They need power, trained handlers and an airline that accepts them on the route. WHO asks that air carriers work under a formal service level agreement that makes them responsible for keeping load temperatures within the profile defined for each product.

Monitoring, labels and handling standards

Data loggers

WHO recommends electronic loggers or other indicators in passive and active containers, with indicator status checked and documented on arrival. Its supplement on transport monitoring adds that single-use loggers should come with a manufacturer's calibration certificate covering their full range, while reusable devices should be calibrated against a traceable reference once a year unless otherwise justified. Before dispatch, ask for the logger serial number, its alarm limits and its calibration certificate, and agree who downloads the data.

IATA label and acceptance checks

IATA's Temperature Control Regulations set requirements for carrying healthcare products by air. According to IATA's pharma page, the Time and Temperature Sensitive label has been mandatory since July 2012 for these shipments. It shows the external transport temperature range and is applied by the shipper or its agent. An acceptance checklist for airlines and ground handlers has applied since July 2013. The label tells handlers how to treat the box, but it does not replace the logger.

CEIV Pharma

IATA's CEIV Pharma programme certifies pharmaceutical handling against an audit checklist linked to the Temperature Control Regulations, covering quality management, staff, facilities, equipment and transport. Certified companies are listed in IATA's ONE Source registry. It is a useful filter when choosing a forwarder, airline or ground handler, but it is not proof that a particular shipment went well.

Dry ice

Frozen products often travel on dry ice, which is regulated as dangerous goods for air transport (UN 1845, Class 9) under the IATA Dangerous Goods Regulations. The package must carry the correct marks and labels, including the net quantity of dry ice, and must let carbon dioxide gas escape. The shipper preparing it needs dangerous goods training.

Planning a lane from India

Lanes differ more than most buyers expect. The table below draws on the cold-chain notes in the country import guides on this site.

A practical planning sequence looks like this:

1. Confirm the labelled range and any permitted excursion with the manufacturer.
2. Secure the destination import permit before booking. Arrival holds for missing paperwork are a common reason a passive shipper runs out of time, which is why the Kenya guide advises confirming the permit and batch numbers on KenTrade before departure.
3. Choose courier or air cargo for the lot size and temperature band, as set out in Courier or air cargo for medicines.
4. Add up door-to-door time: pickup, export clearance in India, flights and connections, destination clearance and inspection, and final delivery. Compare it with the validated duration and keep a margin.
5. Book cool-room space at the arrival airport or the importer's store for the clearance period.
6. Send documents ahead: proforma and commercial invoice, packing list with logger serial numbers, batch certificate of analysis, the import permit and an air waybill consigned to the licensed importer.
7. On arrival, review the temperature data before release, as WHO TRS 1025, Annex 7 expects for cold-chain goods.

The cold-chain transit checker and the lead-time estimator help with steps 4 and 5.

Export clearance in India

Drug shipments leaving India pass through checks by CDSCO port offices, and unapproved, new or banned drugs need an export NOC, described in CDSCO's export NOC guidance. A passive shipper's clock starts when it is packed, so a box packed before these checks are complete loses validated hours while it waits. Documents should therefore be ready, and where possible filed, before the goods are conditioned and packed. Indian export rules buyers should know covers these steps in more detail.

Questions to ask the exporter

• Which packaging system will be used, what is its qualified duration, and was it tested on summer and winter profiles for this payload?
• Which logger is used, what are its alarm limits, where is its calibration certificate, and who downloads the file?
• What is the routing, which hub is used, and is cool-room space booked at each stop?
• Who prepares the dry ice declaration, if dry ice is used?
• What happens if a connection is missed, for example re-conditioning or extra coolant at the hub?
• Which Incoterm and insurance apply? See Incoterms for pharmaceutical exports.
• How will an excursion be investigated? See Temperature excursions in transit.

Clear answers to these questions, set down in writing before dispatch, make the shipment easier to defend if anything goes wrong. A specific lane can be checked through a sourcing request.
