Dry ice for pharma, vaccines and diagnostic samples
Guwahati is where the Northeast's medical cold chain changes hands: samples fly out to reference labs and frozen products come in for seven states. Dry ice is what keeps the frozen part of that chain frozen.
What it is used for
Frozen and ultra-cold products
Products whose label calls for storage at −20 °C or colder, including some vaccines, enzymes, reagents and frozen plasma, travel on dry ice.
Diagnostic samples to reference labs
Serum, plasma and tissue that must stay frozen until they reach a lab in Kolkata, Delhi or Mumbai are packed on dry ice for the flight.
Blood banks and hospitals
Frozen plasma and other frozen components moved between centres, and backup when a plasma freezer fails.
Clinical trial and research shipments
Frozen study samples sent to central labs under the sponsor's packing instructions.

How to do it
Follow the product label and your own quality procedure first. This page is general guidance only.
Use a rigid insulated shipper. Place the product in its secondary pack in the centre and dry ice around and above it.
Leave the shipper able to vent. Never seal dry ice inside an airtight container.
For air freight, mark the outer box “Dry ice” or “Carbon dioxide, solid”, UN 1845, with the net weight of dry ice in kg, and tell the airline when booking.
How much to order
A small sample shipper flying the same day typically carries 3–5 kg. A distributor box on a 24-hour road run needs 5–8 kg. Airlines limit how much dry ice a package and an aircraft may carry, so confirm the limit before packing.
Before you use itMost routine vaccines and many medicines are stored at 2–8 °C and are ruined by freezing. Dry ice is only for products meant to be frozen. If the label says 2–8 °C, use conditioned gel packs, not dry ice.
Questions from this trade
Is dry ice right for 2–8 °C vaccines?
No. Dry ice will freeze and destroy them. It is for products labelled for frozen or ultra-cold storage.
Can samples on dry ice go by air from Guwahati?
Yes, airlines carry dry ice as a Class 9 dangerous good under UN 1845 with weight limits. The box must vent and be marked with the net weight. Confirm with the airline or your courier before booking.
Do you supply certificates or validated shippers?
We supply dry ice blocks. Ask us about any documents your quality team needs before you order, so nothing is assumed.
