We’ve launched our new range of 95kPa biohazard bags, specifically designed for the safe transportation of UN3373 Category B biological substances and fully compliant with Packing Instruction P650.
For laboratories, hospitals, diagnostic centers, veterinary clinics, and research facilities in the United States looking to buy UN3373 compliant packaging, our 95kPa specimen transport bags provide a secure and regulation-ready solution when used as part of a compliant triple packaging system.

95kPa Specimen Transport Bags for UN3373 Compliance
Our 95kPa specimen transport bags are designed to meet the requirements of P650 & 49 CFR 173.199, serving as compliant secondary packaging for the transportation of:
- Blood samples
- Tissue specimens
- Clinical diagnostic materials
- Infectious substances suspected of containing UN3373 Category B substances
The leakproof bags have been independently tested by an impartial laboratory and proven to meet the 95kPa pressure test requirement in accordance with Packing Instruction P650 & 49 CFR 173.199.
For U.S. businesses seeking IATA PI 650 compliant packaging or a complete UN3373 shipping kit, these bags form a critical part of a compliant shipping system.
Fully Compliant with UN3373 Transport Regulations
Our biohazard bags are fully compliant with:
- DOT
- IATA
- IMDG
- Packing Instruction P650
They are trusted by laboratories, hospitals, veterinary practices, biotech companies, and medical facilities worldwide for the secure transportation of biohazardous materials. Whether shipping domestically within the United States by road or internationally by air or sea, our UN3373 compliant packaging solutions help ensure safe handling of clinical and biological samples.
Available Sizes
We offer two sizes of 95kPa biohazard specimen bags:
- BioBag-751 – 7.48in x 10.83in (smaller format)
- BioBag-752 – 10.23in x 13.98in (larger format)
Both options are suitable for use as compliant secondary packaging within a triple packaging configuration.
What are the Packaging Regulations for Shipping UN3373 Specimens?
When shipping UN3373 specimens, it’s essential to understand the packaging requirements. Packing Instruction P650 states that the packaging must consist of at least three components:
- Leakproof primary receptacle(s) (siftproof for solids), e.g. test tubes
- Leakproof secondary packaging (siftproof for solids), e.g. a biohazard bag
- Either the primary receptacle or the secondary packaging must be capable of withstanding an internal pressure of 95 kPa without leakage (for liquids)
- An adequate amount of absorbent material must also be included (for liquids)
- A rigid outer packaging with sufficient strength for its capacity, mass, and intended use.
Our UN3373 specimen bags can be purchased separately or as part of a complete UN3373 shipping kit, providing a full Category B packaging solution compliant with P650 & 49 CFR 173.199.
Compatible UN3373 Shipping Kits
For customers looking to purchase a complete UN3373 compliant packaging system, our BioBags integrate with our triple packaging solutions.
- BioBag-751 can be used with the Code 760 Postal Pack or the mid-size Code 761 Bioshipper 1, which can accommodate up to four BioBags.
- BioBag-752 accommodate cryovial boxes or multiple vials, it’s compatible with the Code 762 Bioshipper 2. The Bioshipper 2 can hold multiple BioBag-752 bags.
These systems form a compliant UN3373 triple packaging kit suitable for transporting Category B biological substances in accordance with P650 & 49 CFR 173.199.
For U.S. organizations seeking UN3373 shipping supplies or 95kPa biohazard bags with box packaging, we offer both individual components and complete kits.

Why Choose Our UN3373 Compliant Packaging?
95 kPa Tested and Certified
We independently test our BioBags to ensure they meet 95 kPa capability requirements. 95 kPa capable clinical bags ensure the packaging will not burst due to atmospheric pressure changes during transit. Watch our inhouse video which demonstrates our bag’s capabilities under 95 kPa pressure.

If shippers use bags that are not tested to 95 kPa capability, there is a risk of leakage. If the bag bursts and leaks infectious contents through the packaging, it could endanger anyone who comes into contact with the shipment, including handlers, drivers, and laboratory personnel, as well as contaminate vehicles, aircraft, or shipping containers.
For U.S. businesses shipping Category B specimens by air, using 95kPa compliant secondary packaging is essential to avoid compliance failures and safety risks.
Unique Barcoding for Specimen Identification
Each BioBag features unique electronic barcoding for specimen and laboratory identification. This helps positively establish identification and link UN3373 specimens to a specific test or patient throughout transport.
Barcoding significantly reduces specimen identification errors in laboratory workflows.
Leakproof, Siftproof & Puncture Resistant
Regulations require a leakproof primary or secondary packaging design for UN3373 liquids, or siftproof for UN3373 solids. Our durable, puncture-resistant self-adhesive bags are proven to meet both leakproof and siftproof requirements.
Integrated Document Pouch
Each bag includes an outer document pouch, ideal for safely storing shipping paperwork alongside UN3373 specimens during transit.
Designed for Use with UN3373 Shipping Kits
Our 95kPa biohazard bags are specifically designed to be used with rigid UN3373 outer packaging to create a compliant triple packaging system.
We offer a range of UN3373 shipping kits developed for transporting Category B substances in accordance with P650 & 49 CFR 173.199. All kits are pre-printed with QR codes that provide quick access to assembly instructions and videos, helping ensure shippers pack UN3373 substances compliantly.
