The short version
Search for guidance on carrying controlled substances aboard a vessel and every result is the regulation itself: the eCFR, Cornell, a Federal Register PDF. The text is authoritative and almost unusable for the person who actually has to run the program.
This walks through 21 CFR 1301.25 paragraph by paragraph, in the order an operator meets it. For the service that provides the registered medical officer, see Controlled Substances; for the rest of the medical program, see all maritime medical services. Every claim below cites the paragraph it comes from, so it can be checked against the source.
Who does 21 CFR 1301.25 actually apply to?
Paragraph (a) sets the scope[1]. Controlled substances may be held for stocking, maintained in, and dispensed from medicine chests, first aid packets or dispensaries aboard:
- Any vessel engaged in international trade, or in trade between ports of the United States
- Any merchant vessel belonging to the US Government
- Any other entity of fixed or transient location approved by the DEA Administrator, for example emergency kits at an industrial field site
The same paragraph also covers aircraft operated under a certificate issued pursuant to the Federal Aviation Act of 1958. If your vessels carry Schedule II-V medication and fall in that first category, this rule governs how you acquire, store, dispense, document and dispose of it, as published in the eCFR. That is the program we run for operators under controlled substances management for vessels.
The medical officer must meet all three conditions
Paragraph (b)[1] is where most in-house programs fail, because it reads like a list of preferences and is actually a set of three simultaneous requirements.
| Condition | What it means in practice | Reference |
|---|---|---|
| Licensed physician | Licensed in a state as a physician. Not a paramedic, nurse or physician assistant. | (b)(1) |
| Employed | Employed by the owner or operator. A consulting agreement does not satisfy this. | (b)(2) |
| DEA registered | Registered at the principal office, or elsewhere if the Form 223 details are readily retrievable at the principal office. | (b)(3) |
“Readily retrievable” is the phrase an inspector uses. If the name, address, registration number and expiration date from the Certificate of Registration cannot be produced quickly at the principal office, the condition is not met, even when a valid registration exists somewhere.
One registration covers a fleet, until a second owner appears
Paragraph (c)[1] is the quiet trap. A registered medical officer may serve more than one vessel under a single registration. That efficiency holds only while those vessels share one owner or operator.
The moment that physician also serves a second owner or operator, the rule requires either a separate registration at the principal office of each owner, or use of the Form 223 documentation route in paragraph (b)(3)(ii).
Fleets change hands, vessels get chartered, and a physician quietly ends up covering two ownership structures under one registration. Nothing visible breaks. The gap only surfaces during an inspection, which is the worst moment to discover it.
What happens when no medical officer is reachable
Paragraph (d)[1] anticipates the realistic case: no officer is employed, or one exists but cannot be reached, and medication is needed now. The master or first officer, who is expressly not registered under the Act, may purchase directly.
The procedure is specific. The officer must personally appear at the vendor place of business with proper identification, such as a Seaman photographic identification card, and present a written requisition. That requisition must be on the vessel official stationery or purchase order form and must include:
- The vendor name and address, and the controlled substance name and description (dosage form, strength, volume per container)
- The number of containers ordered
- The vessel name, official number and country of registry
- The owner or operator of the vessel, and the port where the vessel is located
- The signature of the ordering officer and the date of the requisition
If the situation is clinical rather than procedural, a crew reaching a physician matters more than a purchase order. That is what SeaDoc telehealth covers, and it works alongside this rule rather than replacing it.
The paperwork: requisitions, records of sale, and who keeps which copy
Paragraph (d)(3)[1] sets a triplicate record of sale, and the three copies do not go to the same place. Getting this wrong is a documentation finding even when the purchase itself was lawful.
| Copy | Where it goes | Timing |
|---|---|---|
| Copy 1 | Filed with the vendor controlled-substances records, with the vessel requisition attached | At sale |
| Copy 2 | Given to the vessel officer and retained aboard the vessel | At sale |
| Copy 3 | Forwarded to the nearest DEA Division Office | Within 15 days after the end of the month of sale |
Disposal is governed separately, under 21 CFR part 1317[2], and paragraph (i) limits distribution of these controlled substances to persons under the general supervision of the medical officer, except as part 1317 allows.
Two annual reports, two different clocks
This is the detail most operators miss entirely, because the two reports sound like one obligation and are not.
| Report | Who prepares it | Dated to | Reference |
|---|---|---|---|
| Medical officer report | The medical officer | The date the officer registration expires | (e) |
| Master report | The master of the vessel | Each calendar year | (h) |
Both reports are defined in the regulation. The officer report gives a detailed accounting for each vessel plus a summary across all vessels under supervision, for everything purchased, dispensed or disposed of. The master files their report with the medical officer, or keeps it with the required records where no officer is employed. Both must be delivered to the Administration on request.
Paragraph (e) also settles a question crews ask often: the medical officer does not need to be present when controlled substances are dispensed, provided the person dispensing is responsible to that officer and can justify their actions.
Why compliance protects you from being called an importer
Paragraph (g)[1] contains the protection that makes the rest worth doing. Owners and operators who acquire, store and dispense in accordance with this section are not deemed to possess or dispense those controlled substances.
The same paragraph, read with Article 32 of the 1961 Single Convention on Narcotic Drugs[3] and Article 14 of the 1971 Convention on Psychotropic Substances, means those owners and operators are not deemed to import or export controlled substances carried in compliance. Compliance is what creates that protection. Non-compliance removes it.
The inspection-readiness checklist
Crew certification sits under a different rule set entirely, covered in Fit-for-Duty. Everything below should be producible without a search. If it is not, “readily retrievable” is the phrase that will appear in the finding.
- The medical officer Form 223 details held at the principal office
- Evidence the officer is state-licensed and employed by the owner or operator
- Copy 2 of every record of sale, retained aboard each vessel
- The written requisition on vessel stationery, with official number and country of registry
- The medical officer annual report, dated to registration expiry
- The master calendar-year report for each vessel
- Disposal records consistent with 21 CFR part 1317
- The medicine chest those substances live in, mapped to your flag state. See MedChest
- Evidence that anyone dispensing was responsible to the medical officer
Common questions
Does a vessel need its own DEA registration?
No. The registration attaches to the medical officer, not the vessel. It is held at the principal office of the owner or operator, or at another location provided the Form 223 details are kept at the principal office in a readily retrievable manner, per 21 CFR 1301.25(b)(3). We hold that registration for operators under Controlled Substances management.
Can a consultant physician serve as the medical officer?
No. Paragraph (b)(2) requires the medical officer to be employed by the owner or operator. A consulting agreement does not satisfy that condition, which is one of the most common compliance failures we see. See the three conditions in full.
What happens if the master buys medication without a medical officer?
Paragraph (d) permits it. The master or first officer, who is not registered, may purchase from a registered manufacturer, distributor or authorized pharmacy by appearing in person with photo identification and a written requisition on the vessel’s official stationery. The full procedure is in the regulation text.
How long does the vendor have to notify the DEA of the sale?
Copy 3 of the record of sale goes to the nearest DEA Diversion Control Division Office within 15 days after the end of the month in which the sale was made, per paragraph (d)(3).
Does this rule cover the rest of the ship medicine chest?
No. 21 CFR 1301.25 governs only the controlled substances. The rest of the chest follows MLC 2006 Standard A4.1 and your flag-state rules, which we cover under MedChest. For advice at sea, see SeaDoc Telehealth, and for crew certification, see Fit-for-Duty.
