Shipping biological samples is heavily regulated, with many rules and protocols that must be followed
Show
If you’re reading this, you’re planning to ship an “exempt” biological substance, one that doesn’t fall into Category A or B. If you need a refresher on which category your substance falls under, see our companion article. Here, we’ll review requirements for packaging, labeling, marking and documentation for shipping exempt biological substances. How to Identify an Exempt Patient/Human/Animal Specimen“Exempt” materials are a broad and common categorization, yet this category is often the most unfamiliar to many. Exempt materials are defined as “those collected directly from humans or animals, including, but not limited to, excreta, secreta, blood and its components, tissues and tissue fluid swabs, and body parts being transported for purposes such as research, diagnosis, investigational activities, disease treatment, and prevention.” IATA/DOT/USPS doesn’t want to overburden medical professionals shipping relatively benign samples, so these fall under more lax regulations. Some examples of Exempt Patient/Human/Animal Specimens:
If you’re unable to make a professional judgment on the presence of pathogens, don’t use the “exempt” classification, instead use UN3373 Category B unless there is a pathogen on the Category A list. Packaging InstructionsFollow and save any instructions provided with boxes and validated thermal shippers you purchase, so you always have something to reference. Triple packaging is the best practice for all classifications of biological shipments. Here are the four elements you need for your packaging:
This contains your sample — make sure it has a leak-proof seal, tape or parafilm screw cap.
This is your inner container. Ensure the primary or secondary receptacle can withstand: Pressure: not less than 95kPa. Temperature:- 40°C to 55°C
Note: This does not include Styrofoam layer, if using wet/dry ice. Express carriers such as FedEx and UPS do not accept packages with a Styrofoam container as the outside packaging so add rigid outer packaging such as a cardboard box or validated thermal shipper. Disposing of or Repurposing Rigid Outer Packaging Before empty packaging is returned to the consignor, or sent elsewhere, it must be disinfected or sterilized to nullify any hazard and any label or mark indicating that it contained an infectious substance must be removed. When shipping blood samples A biohazard symbol is required on any sample that contains human blood and other potentially infectious materials (OPIM). This label must be affixed to the primary receptacle or secondary packaging. Overpack An overpack is an extra outside packaging used when shipping multiple boxes to the same address or used to refrigerate materials being shipped in a smaller box. All markings and labels must be on the outside of the box along with the word “OVERPACK”. Since your inside package is the “triple package” you need all markings and labels on that package as well. Labeling Instructions
Standardized labeling must be affixed to the outside. When the package dimensions are adequate, labels must be located on the same surface of the package near the Proper Shipping Name mark. Except for the orientation arrows, mount all labels and markings on the front side of the box — all on one surface area. “Cargo Aircraft Only” labels are required when applicable. The outer shipping container must be marked on the address side with the words “Exempt human specimen” or “Exempt animal specimen,” as appropriate. Orientation Arrows Label If you are shipping a liquid, orientation arrows are required. Label must be affixed on 2 opposite sides and perpendicular to the front of the package. Orientation arrows should be red or black on a contrasting background. Overpack Label Overpack labels have a height Requirement of 12mm (~0.5 inch). Either of these styles is acceptable:
Documentation RequirementsAll Shipments must include:
Contact the Receivers Make sure you contact the receivers prior to shipping. Keep in mind that some labs only receive Monday to Thursday. If you ship on Friday, it might sit over the weekend, or arrive on Saturday and nobody's there. If they are open on Saturday, make sure you label for Saturday delivery so the carrier knows they can deliver on Saturday and not hold the package over the weekend. Know the stability of your sample and how long it can last, roughly 6% of Express Carrier shipments are not delivered on the requested date for a variety of reasons. Think carefully of the day you’re shipping and the stability of the shipment to avoid a potential re-draw from the patient. Other FedEx and UPS Requirements
International shipments Before you ship any material abroad, you should answer the following questions:
Penalties and Fines Shipping biological substances is a tightly regulated activity. If you need more reasons to get it right, here is a list of violations and the minimum assessments for each: Which of the following can be shipped as exempt human specimens?Examples of specimens which may be transported as Exempt include: the blood or urine tests to monitor cholesterol levels, blood glucose levels, hormone levels, or prostate specific antigens (PSA); tests required to monitor organ functions such as heart, liver, or kidney function for humans or animals with noninfectious ...
What is the maximum package quantity limit for a liquid exempt patient specimen?For liquid specimens, the outer container must not contain more than a total of 4 liters (L) (excluding ice or dry ice used to keep specimens cold). For solid specimens, the outer container must not contain more than a total of 4 kilograms (kg).
Which of the following is a requirement for the outside container when shipping diagnostic specimens?The outer container must consist of corrugated fiberboard, wood, metal or rigid plastic and be appropriately sized for its contents. Dry ice or ice packs/freezer blocks are placed between the secondary container(s) and the outer container when the specimens require refrigeration.
Which special provisions apply to UN 3373 biological substance Category B shipments?“Biological Substance, Category B” must appear in 6-mm-high text on the outer package adjacent to a diamond-shaped mark like the one shown here. The UN 3373 marking must be in the form of a square set at an angle of 45 degrees. Each side of the UN 3373 diamond should measure a minimum of 2" (50 mm).
