In the fast-paced world of diagnostics, pharmaceutical innovation, and medical research, the secure transport of biological samples is mission-critical. From blood and plasma to tissue biopsies and cell cultures, these materials are often time-sensitive, irreplaceable, and subject to strict compliance requirements. So, the real question isn't just "how to ship biological samples internationally," but how to do it right — with speed, precision, and regulatory confidence.
That’s where DHL Express Medical Express (WMX) comes in. Tailored for biological specimen shipping, this specialized service empowers institutions in Sri Lanka to navigate the complexities of international logistics with ease.
Ensuring sample integrity with DHL Express’ specialized handling and technology
Validated packaging solutions for diverse types
Each biological sample is unique, and so are its shipping requirements. Whether you're looking to understand how to ship blood samples or transport tissues or genetic materials, our solutions are designed to maintain the integrity of your samples throughout transit. Our biological sample packaging options include:
Sample type | Packaging option |
Blood and Serum | Leak-proof primary containers, absorbent materials, and rigid secondary packaging, compliant with UN3373 standards. |
Tissue and Biopsy Samples | Preserved using validated packaging, with dry ice in various formats (pellets, sticks, plates) to maintain condition whether frozen or formalin-fixed. |
DNA and RNA Samples | Encased in absorbent sleeves and thermally protective packaging to guard against temperature shifts, shock, and contamination. |
Cell Cultures | Shipped in temperature-controlled containers with integrated data loggers to maintain viability from origin to destination. |
For cryogenic samples, we provide liquid nitrogen shippers that maintain ultra-low temperatures (below -150°C). For refrigerated samples (2–8°C), our DHL Express temperature-controlled shipping solutions use insulated gel pack systems to ensure stable cold chain logistics. Even ambient temperature shipments benefit from protective liners designed to minimize thermal fluctuations.
To guarantee the integrity of every shipment, DHL Express validates packaging through a combination of electronic tracking, physical inspection, and strict adherence to industry standards. Our system allows you to scan barcodes or enter Stock Keeping Units (SKUs) to confirm that each item is packed correctly within an order. We provide comprehensive packaging guidelines on using strong materials, ensuring proper filling, and sealing to secure the safe transit of your biological samples.
Proactive monitoring and intervention for peace of mind
Furthermore, DHL Express WMX combines real-time tracking with proactive operational support to ensure your shipments remain secure and compliant at every step.

- Certified handling expertise: At DHL Express, our staff includes individuals certified by International Air Transport Association (IATA), ensuring that shipments, such as UN3733 (biological substances)and UN1845 (dry ice) are managed according to the highest standards of safety and compliance.

Navigating complex regulations for biological shipments

We ensure the correct handling of paperwork, so you can focus on the science while we handle the logistics of how to ship biological samples internationally.
Expert guidance on documentation and permits
- Permits and Customs Declarations: While you are responsible for document preparation, we offer advice on the permits and customs paperwork required for shipping biological samples, helping you avoid delays and ensure smooth customs clearance.
- Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and Phytosanitary Certificates: Specific certificates such as CITES or phytosanitary documents may be necessary for shipments involving animal-derived or plant-based materials. DHL Express WMX guides you on when these are required and how to obtain them according to both the origin and destination country laws.
- Dangerous Goods Declarations: Certain biological samples, like vaccines or diagnostic specimens, may be classified as dangerous goods under IATA’s Dangerous Goods Regulations. DHL Express WMX offers expert guidance to help you correctly declare and package these shipments in line with the transport of biological sample regulations.
Minimizing delays and ensuring compliance
The margin for error in biological specimen shipping is exceptionally slim — one mislabeled package or missing document can trigger customs delays or even return-to-sender issues. That’s why every aspect of your shipment, from labeling to packaging, is managed in line with internationally recognized safety standards, including strict adherence to IATA regulations for the transport of dangerous goods. This meticulous approach removes uncertainty, supports cross-border compliance, and results in faster customs clearance, reduced risk of sample degradation, and fewer operational disruptions.
