A pharmaceutical waste container is a closed, labeled receptacle in which a healthcare facility accumulates unwanted medicines until a permitted hauler collects them. For hazardous waste pharmaceuticals, the federal rule sets short, specific requirements: the container must be structurally sound, compatible with its contents, kept closed and secured, and marked with a set phrase. This page translates those requirements into a checklist of container properties for clinic staff, buyers and students.
This page describes products and general use; it is not medical advice.
Who uses it: healthcare facilities such as clinics, hospitals and pharmacies that generate unwanted medicines, and the staff who procure and handle their waste streams. For the disposal rules themselves (generator status, manifests, hauler selection), see the companion guide on pharmaceutical waste disposal; this page is about the container.
What a pharmaceutical waste container is
It is a container used to accumulate pharmaceutical waste on site. The regulation that governs the hazardous subset is the EPA’s Hazardous Waste Pharmaceuticals rule, 40 CFR Part 266 Subpart P. Section 266.502(d) sets the standards for containers used to accumulate non-creditable hazardous waste pharmaceuticals at healthcare facilities, and section 266.502(e) covers labeling. Whether a given pharmaceutical is a hazardous waste pharmaceutical is a separate determination the facility must make under 266.502(c), by checking whether it exhibits a hazardous characteristic or is a listed waste under 40 CFR Part 261.
Hazardous waste pharmaceuticals are not the same stream as chemotherapy trace waste or regulated medical waste; those are covered in chemotherapy waste disposal and UN3291 regulated medical waste.
What federal rules require of the container
For non-creditable hazardous waste pharmaceuticals at a healthcare facility, 40 CFR 266.502 sets these container-related requirements (text checked against the Legal Information Institute copy of the eCFR on 2026-11-01):
| Container property | What the paragraph says | Citation |
|---|---|---|
| Condition | Structurally sound, compatible with its contents, and lacking evidence of leakage, spillage, or damage that could cause leakage under reasonably foreseeable conditions | 266.502(d)(1) |
| Incompatible or reactive contents | For ignitable or reactive waste, or mixed incompatible waste, manage the container so it cannot generate extreme heat or pressure, fire, explosion or violent reaction, or damage its own structural integrity | 266.502(d)(2) |
| Closure and security | Keep closed and secured in a manner that prevents unauthorized access to its contents | 266.502(d)(3) |
| Label | Label or clearly mark each container with the phrase “Hazardous Waste Pharmaceuticals” | 266.502(e) |
| Accumulation time | Up to one year without a permit; the facility must be able to show how long the waste has been accumulating, by dating the container, keeping an inventory, or using a designated area with the earliest date identified | 266.502(f)(1)-(2) |
Color codes: a convention, not a rule in these paragraphs
Paragraphs (d) and (e) of 266.502 specify condition, closure, security, compatibility and a label phrase. They do not mention container color. Color schemes you see on commercial containers are therefore a matter for your waste hauler, your state program and your internal policy, and you should confirm what your hauler and state require rather than assuming one scheme applies everywhere.
Types and variants
The rule distinguishes containers by what goes in them rather than by shape or size. Every row below traces to 266.502.
| Type | Typical use | Key difference | Source |
|---|---|---|---|
| Container for hazardous waste pharmaceuticals | Accumulating non-creditable hazardous waste pharmaceuticals | Must be marked “Hazardous Waste Pharmaceuticals,” closed and secured, and show accumulation start | 266.502(d)-(f) |
| Shared container for hazardous and non-hazardous pharmaceuticals | Facilities that manage non-hazardous pharmaceutical waste under the same standards | The rule allows both in the same container, and allows a facility to choose to manage non-hazardous pharmaceuticals as hazardous waste pharmaceuticals under the subpart | 266.502(c), (d)(4) |
| Separate container for restricted waste | Waste barred from combustion by the dilution prohibition (metal-bearing waste codes in 40 CFR Part 268 appendix XI) or from lab packing (appendix IV codes) | Must be accumulated in separate containers and labeled with all applicable EPA hazardous waste numbers | 266.502(d)(4) |
How to choose: a verification checklist
These are the criteria the regulation itself states. Each maps to a paragraph you can point to when you review a container or a vendor listing.
- Label: can the container be marked with “Hazardous Waste Pharmaceuticals” (266.502(e))? The requirement is that the phrase is on each container.
- Integrity and compatibility: is the container structurally sound and compatible with what it will hold, with no leakage or damage (266.502(d)(1))?
- Closure and access: does it close and can it be secured against unauthorized access (266.502(d)(3))?
- Dating: is there space to record when waste first became waste, or an inventory or designated-area method in place (266.502(f)(2))?
- Segregation: will you need separate containers for ignitable, reactive, incompatible or combustion-restricted waste (266.502(d)(2), (d)(4))?
- Hauler and state: confirm what your hauler accepts and whether your state has adopted the rule. EPA states that authorized states are required to adopt the final rule and that it is not effective in an authorized state until that state adopts it (EPA FAQ on Subpart P).

Safe use and handling basics
- Keep containers closed and secured so that unauthorized people cannot reach the contents (266.502(d)(3)).
- Replace a container that shows leakage, spillage or damage; the rule says a container must lack evidence of it.
- Do not put reactive or ignitable waste together with incompatible material in a way that could cause heat, pressure, fire or a violent reaction.
- Ensure personnel who manage the waste are thoroughly familiar with proper waste handling and emergency procedures relevant to their responsibilities (266.502(b)).
- Do not sewer hazardous waste pharmaceuticals. Section 266.505 prohibits healthcare facilities, including very small quantity generators, from discharging them to a sewer system that passes through to a publicly owned treatment works. EPA also “strongly discourages sewering of any pharmaceutical in any setting.”
Laboratory settings handling mixed chemical streams should also see lab waste disposal.
Common mistakes
- Assuming a container color satisfies the label requirement. The rule requires the phrase, not a color.
- Leaving containers open or unsecured between uses.
- Not tracking when waste first became waste, so the one-year accumulation limit cannot be demonstrated.
- Treating the federal text as the whole picture when your state may have its own program or may not yet have adopted Subpart P.
- Sending hazardous waste pharmaceuticals down a drain instead of into a container; a drain is not a disposal route for them (266.505).
FAQ
Does federal law require a specific color of pharmaceutical waste container?
The container paragraphs of 40 CFR 266.502 (d) and (e) do not mention color. They require a sound, compatible, closed and secured container marked “Hazardous Waste Pharmaceuticals.” Check your hauler and state program for any color convention.
What must be written on a hazardous pharmaceutical waste container?
The phrase “Hazardous Waste Pharmaceuticals” (266.502(e)), plus a date or an equivalent method showing when the waste began accumulating (266.502(f)(2)).
Can hazardous and non-hazardous pharmaceuticals share a container?
Generally yes under 266.502(d)(4), except for waste restricted by the dilution prohibition or from lab packing, which must be in separate containers.
How long can a healthcare facility keep the container on site?
One year or less without a permit, for non-creditable hazardous waste pharmaceuticals (266.502(f)(1)).
