Short answer
A medical logistics company is a firm that stores, moves or coordinates healthcare goods or specimens. “Medical logistics” is a trade label, not a legal category: federal rules name specific roles instead, such as a third-party logistics provider for prescription drugs, a wholesale distributor, or a carrier, and they set packaging rules for infectious-substance specimens. Work out which role a firm holds before comparing it with another.
Definition and scope
Federal law does not define “medical logistics company” as a term. It defines roles, and a single business can hold more than one. For the physical flow of supplies from manufacturer to bench, see medical supply logistics; for courier vendors specifically, see how to evaluate medical courier companies. This page does something narrower: it sorts company types by what the law says each role is, then lists what a buyer can ask each type to show.
How the company types differ
Each row below is limited to what the cited text says. The first two rows come from the drug supply chain statute, which covers prescription drugs only.
| Role | What the text says | Source |
|---|---|---|
| Third-party logistics provider (drugs) | An entity that “provides or coordinates warehousing, or other logistics services” of a product in interstate commerce on behalf of a manufacturer, wholesale distributor or dispenser, but does not take ownership of the product or have responsibility to direct its sale or disposition. | 21 U.S.C. 360eee(22) |
| Wholesale distributor (drugs) | A person engaged in wholesale distribution, other than a manufacturer, a manufacturer’s co-licensed partner, a third-party logistics provider, or a repackager. | 21 U.S.C. 360eee |
| Carrier (devices) | Carriers are exempt from device establishment registration “by reason of their receipt, carriage, holding or delivery of devices in the usual course of business as carriers.” | 21 CFR 807.65(h) |
| Preparer of a specimen package (Category B) | The packaging manufacturer and subsequent distributors must give the consignor or person preparing the package clear instructions for filling and closing it, and keep a copy for at least one year. | 49 CFR 173.199(a)(10) |
Two limits matter. First, the statute’s definition of “product” is “a prescription drug in a finished dosage form for administration to a patient”, so the third-party logistics definition does not cover devices, lab consumables or reagents. A firm that calls itself a “3PL” for lab goods is using the trade term, and this statute does not define it. Second, the carrier exemption in 21 CFR 807.65(h) concerns establishment registration only; it says nothing about other rules a carrier must follow. For how drug-side duties attach to distributors, see the Drug Supply Chain Security Act guide; for the device-side wholesaler role, see medical supply wholesaler vs distributor vs manufacturer.
What the packaging rule says for specimen shipments
If a company will carry diagnostic specimens classed as Category B infectious substances, the U.S. Department of Transportation text in 49 CFR 173.199 sets the packaging. The rows below are packaging requirements that a buyer can check on a sample package or a written procedure.
| Requirement | What 49 CFR 173.199 says |
|---|---|
| Structure | Triple packaging: a primary receptacle, a secondary packaging and a rigid outer packaging (a)(1). |
| Liquids | The primary receptacle and the secondary packaging must be leakproof, with absorbent material between them (b)(1)-(3). |
| Solids | The primary receptacle and the secondary packaging must be siftproof (c)(1), (c)(3). |
| By aircraft, pressure | The primary receptacle or the secondary packaging must withstand, without leakage, a pressure differential of not less than 95 kPa (0.95 bar, 14 psi) (b)(4). |
| By aircraft, quantity (liquids) | No more than 1 L per primary receptacle and 4 L per outer packaging; the outer limit excludes ice, dry ice or liquid nitrogen used to maintain the material (b)(5). |
| Drop test | The packaging must pass the drop test in 49 CFR 178.609(d) from at least 1.2 m (3.9 ft) with no leakage from the primary receptacle (a)(4). |
| Marking | A square-on-point mark with no side under 50 mm (1.97 in), and the words “Biological substances, Category B” beside it in letters at least 6 mm high (a)(5). |
| Emergency contact | A name and telephone number of a knowledgeable person, on a written document such as an air waybill or on the outer packaging (a)(7). |
This table is about packaging specimens. It does not cover Category A substances, international air rules or dry-ice labeling, so ask a carrier which rule set its procedures follow. For the cold-chain side, see cold chain shipping vendor evaluation, and for the courier service model, medical courier services.
What to ask each type to show
The items below are editorial: each turns one rule from the sections above into a question. None is a legal test of a particular company.
- A firm describing itself as a 3PL for drugs: ask who owns the product while it is in the firm’s care and who directs its sale or disposition. Under the 360eee(22) definition, a firm that does neither is a third-party logistics provider; a firm that does either is describing a different role.
- A firm describing itself as a distributor or wholesaler: ask whether it takes ownership of the goods and whether the goods are drugs or devices, since the drug statute and the device rules treat the roles differently.
- A carrier or courier: ask for its written specimen packaging procedure and check each row of the packaging table against it. Ask who supplies the packaging and whether the packaging manufacturer’s filling and closing instructions are on file (a)(10).
- Any firm shipping by air: ask how the 95 kPa pressure and the 1 L / 4 L liquid limits are met.
Common misunderstandings
- “3PL” always means the statutory term. The statute defines it for prescription drugs only. For lab consumables or devices it is a trade label.
- A carrier is exempt from everything. 21 CFR 807.65(h) exempts carriers from device establishment registration; it does not exempt them from packaging or marking rules for the specimens they carry.
- Any sturdy box is a specimen package. The Category B text requires three layers, leakproof or siftproof containment, a drop test and specific marking.
- One company type is better. The sources define roles, not rankings. The right type depends on what is being moved: drugs, devices and supplies, or specimens.
FAQ
What is a medical logistics company?
It is a trade label for a firm that stores, moves or coordinates healthcare goods or specimens. Federal text defines specific roles instead, such as third-party logistics provider (for prescription drugs), wholesale distributor and carrier.
Does the statutory 3PL definition cover lab consumables or devices?
No. 21 U.S.C. 360eee defines “product” as a prescription drug in a finished dosage form, so the definition applies to prescription drugs only.
Are carriers exempt from all device rules?
No. 21 CFR 807.65(h) exempts carriers from device establishment registration for receiving, carrying, holding or delivering devices in the usual course of business as carriers. It says nothing about other rules.
What does the law require for packaging Category B specimens?
49 CFR 173.199 requires triple packaging, leakproof or siftproof containment, a drop test, marking with the square-on-point mark and the words “Biological substances, Category B”, and an emergency contact. See the table above.
