Navigating the Complexities of Shipping Human Biological Samples: A Comprehensive Guide

Shipping human biological samples requires meticulous handling and strict compliance with regulations to ensure safety and legal compliance. Additionally, efficient door-to-door logistics are essential to maintaining sample stability while prioritising patients’ health.  

Unlocking the Unknown of Shipping Human Biological Samples: A Definitive Roadmap

  • Classification and Declaration

    Human biological samples, like blood, human cells, urine or saliva, are usually classified as Category B Biological Substances and/or UN3373 according to international rules from bodies like the International Air Transport Association (IATA) and the International Civil Aviation Organization (ICAO). When shipping, the sender must accurately declare what’s inside the package on the shipping paperwork, specifying that it contains Category B Biological Substances/UN3373 and providing details about the samples. The shipper must confirm the end purpose of the sample (i.e. it is used for testing to be destroyed after or used for manufacturing).

  • Packaging

    Samples must be packed in purpose-built packaging solutions, like tubes or vials, that won’t leak or break. These containers should use secondary solid packaging, including absorbent material, to remove leaks. The samples can be transported in various temperatures depending on the sample type and the end purpose. (see whole CRYOPDP temperatures)

  • Labelling

    Correctly labelling the package is vital for identification and safe handling. Labels should state the proper shipping name, Category B Biological Substance, include the UN3373 marking for international shipments, and have the sender and recipient’s details. The shipper must have a biohazard symbol and special handling instructions or warnings. The correct statement needs to be shown on the airline/carrier shipping paperwork so this is handled accordingly and stored at the right temperature while in transit.

  • Documentation

    To cross a country’s customs borders with a shipment, official declarations to customs authorities are required, making a customs Invoice essential for clearance. The responsibility for compliance with the regulations of the countries involved, as well as providing the necessary customs documents, is shared by both the exporter and importer. Recent trends have revealed varying levels of accuracy and completeness in customs invoices, with many lacking critical information needed for import customs clearance. It’s important to remember that shipping documents are reviewed by the CRYOPDP International Logistics Team and the customs authorities responsible for clearance. Therefore, ensuring that the customs invoice is in English and contains all required details is crucial. A thorough Customs Invoice meets requirements and facilitates a smoother and faster customs clearance process, reducing delays and ensuring a more efficient procedure.

You’ll need various documents depending on where and how you’re sending the samples. These could include an air waybill, a shipper’s declaration for dangerous goods, customs forms, a packing list detailing what’s inside, and any necessary permits or licences. 

It’s a comprehensive list of documents for the International Shipping of Biological Samples:

  • Air Waybill (AWB): A document the carrier (airline) issued acknowledging receipt of goods for transport, detailing the shipment’s destination and contents.
  • Shipper’s Declaration for Dangerous Goods (if applicable): This declaration is required for hazardous materials shipments. It must declare the dangerous goods’ nature, quantity, and handling instructions.
  • Customs Forms: Documentation required by customs authorities to facilitate the clearance of goods across international borders. It may include customs declarations, import/export permits, and other relevant forms.
  • Packing List: An itemised list detailing the shipment’s contents, including descriptions, quantities, and values of each item.
  • Permits or Licences: Any necessary permits or licences required for the import/export of biological samples, such as health permits, import licences, or CITES (Convention on International Trade in Endangered Species) permits for samples derived from protected species.
  • Certificate of Origin (if applicable): A document certifying the country of origin of the goods, which may be required for customs clearance purposes.
  • Documentation Specific to Biological Samples: This may include a Material Safety Data Sheet (MSDS) detailing the hazards and handling precautions associated with the biological samples and any other relevant documentation specific to the nature of the samples being shipped.
  • Invoice: see above
  • Export Control Documents (if applicable): Documents required to export certain controlled goods, such as dual-use items, subject to export controls.
  • Certificate of Analysis (if applicable): A document certifying the quality and composition of the biological samples, which may be required for regulatory compliance or quality assurance purposes.
  • Other Regulatory Documentation: Depending on the destination country and the nature of the samples, additional regulatory documentation may be required to ensure compliance with local regulations and standards.
  • Carrier-Specific Documentation: Any additional documentation required by the chosen carrier (e.g., shipping instructions, booking confirmation, or transport contract).


The shipper and the logistics provider must choose a reputable carrier with experience handling biological samples. Ensure the carrier follows the regulations and has the proper facilities for safe transportation. Use faster shipping methods to keep transit times short and maintain sample quality.

It is crucial to remember that when shipping via air, civil aviation security regulations must be adhered to; cargo planned to travel by air must be security screened by a Civil Aviation Authority (CAA) or the equivalent in other countries, approved method of screening like X-Ray, Explosive Detection devices (ETD), Free Running Explosive Detection Dogs (FREDDS), hand search etc. For human cells or genes transported for Cell & Gene Therapy purposes, the commodity might be destabilised or damaged by an X-ray screening; this is why it is essential that before shipping, the shipper plans for this ahead of time By contacting the CRYOPDP team in the UK you would receive complete guide guidance for steps to take to ensure your commodity is shipped safely. Our team will consider the commodity type packaging type, perform a risk assessment, and advise you on the best course of action. 

Regulations Compliance

The shipper must be familiar with the rules for shipping biological samples in your country and any international regulations that apply. Ensure all packaging, labelling, and documentation meet these regulations to avoid delays or rejection during transit. 


Anyone packing and shipping biological samples should receive proper training to handle them safely and comply with regulations.
