The short version
- A Ship Sanitation Control Exemption Certificate is an International Health Regulations instrument, not a US one. The United States does not require you to present it at a US port[1].
- A cargo vessel cannot obtain an SSC or SSCEC anywhere in the United States. CDC states this directly[1].
- No US port authority, public agency or private company is authorised to issue one, and any certificate a US private company sells you is not valid[1].
- The only US exception is the CDC Vessel Sanitation Program, which may issue one on request during a cruise ship inspection[1].
- Certificates run six months with a possible one month extension[8], so a US-flag vessel on a foreign voyage has to plan renewal around a foreign port.
- The US duty that does bite is the 42 CFR 71.21 report of death or illness before arrival[4].
Every guide to ship sanitation certificates skips the one fact a US operator needs
Search the term and page one fills with general explainers, a Wikipedia entry and a row of port agents and pest control firms offering to arrange your certificate. Not one of them tells a US operator the thing that actually governs their situation.
CDC states it in plain terms: “Cargo vessels cannot obtain a ship sanitation control or exemption certificate in the United States.”[1] The same page adds that no port authority, public agency or private organisation in the United States is authorised to issue one, and that any certificate issued by a private company in the United States is not valid[1].
That is a commercial warning as much as a regulatory one. Operators do buy these. The document arrives, it looks official, and it is worth nothing at the next port state inspection.
CDC Port Health, Ship Sanitation Certificate Information
“CDC currently does not require ships to present ship sanitation certificates when calling at U.S. ports. Cargo vessels cannot obtain a ship sanitation control or exemption certificate in the United States.”[1]
What the certificate is, and which instrument creates it
The SSC replaced the old Deratting Certificate when the World Health Organization adopted the revised International Health Regulations in 2005[2]. Two documents sit under one name. A Ship Sanitation Control Exemption Certificate is issued when the competent authority finds no evidence of a public health risk on board. A Ship Sanitation Control Certificate is issued when a risk was found and control measures were applied[3].
The inspection looks at the areas a physician would expect: potable water, galley and food handling, waste and sharps disposal, ballast and bilge, accommodation, and vector or rodent evidence[3]. It is a vessel hygiene inspection, not a crew health inspection, and it does not look inside your medicine chest.
| Question | The instrument says | What that means for a US operator |
|---|---|---|
| Who creates the duty | IHR (2005), a WHO instrument binding on States Parties[2] | Your flag state and the ports you call at enforce it. Not the USCG |
| Who issues it | The competent authority at an authorised port[3] | No US port is on that list for cargo vessels[1] |
| Validity | Six months, extendable by one month if inspection is not practicable[8] | Renewal has to be planned around a foreign call |
| US requirement to present | Not imposed[1] | No US port will ask you for it |
| US ability to issue | VSP may issue on request during a cruise ship inspection[1] | Cargo, fishing, towing and OSV tonnage is excluded |
| Private US certificates | Not authorised[1] | “Any certificates issued by private companies in the United States are not valid”[1] |
Why the United States sits outside a system almost every other port uses
The US public health authority over arriving vessels does not run through certificates. It runs through 42 U.S.C. 264, which authorises regulations to prevent the introduction of communicable disease[7], and through 42 CFR part 71. Those rules give CDC a reporting duty and an inspection power, not a certification scheme[4][5].
The practical consequence is a split most operators never see coming. A vessel can hold a perfectly valid SSCEC and still be boarded and detained under 42 CFR 71.33 if an ill person is aboard[12]. The certificate says the ship is clean. It says nothing about the people on it.
The reverse trap is worse. A US-flag vessel that has been trading domestically for a year, then takes a foreign fixture, has no route to a certificate at home and arrives at a foreign port with an expired document.
The cruise exception, and how narrow it is
CDC’s Vessel Sanitation Program is the only US body that touches this for commercial passenger vessels. VSP jurisdiction reaches cruise ships carrying 13 or more passengers on a foreign itinerary with US ports[6], operating under the authority of 42 U.S.C. 264[7]. Within that jurisdiction VSP runs unannounced operational inspections[10] and may issue an SSCC or SSCEC on request during one[1].
Read the threshold carefully. Thirteen passengers, and a foreign itinerary. A Subchapter T passenger vessel on a domestic run is outside it. So is every cargo hull, every fishing vessel, every towing vessel and every offshore supply vessel.
| Vessel | Inside CDC VSP? | Route to a certificate |
|---|---|---|
| Cruise ship, 13+ passengers, foreign itinerary with US ports | Yes[6] | VSP may issue on request during an inspection[1] |
| Cargo vessel, any tonnage | No | No US route at all. Foreign authorised port only[1] |
| Passenger vessel on a domestic run | No, the itinerary limb fails[6] | Foreign authorised port only |
| Fishing, towing, OSV, research | No | Foreign authorised port only |
CDC’s vessel sanitation rules sit in 42 CFR part 71 subpart D, and they are written as an inspection and control scheme rather than a certification scheme[9]. That is the structural reason the United States has no issuing authority for cargo tonnage: the regulation was never built to produce a certificate.
What a US operator should actually do
The certificate question is a voyage planning question, not a compliance purchase. Five steps, in order.
- Check the expiry before you fix the voyage, not after. Six months is short and the clock runs from issue, not from the last inspection[8]. If the certificate expires mid-voyage, the renewal port is a commercial decision that belongs in the fixture.
- Identify an authorised port on the intended route. WHO maintains the list of ports authorised by each State Party[3]. Your agent can confirm, but the obligation to arrive with a valid document is the company’s.
- Do not buy a certificate in the United States. CDC states plainly that private US certificates are not valid[1]. The money is wasted and the document creates a false record in the ship’s file.
- Prepare the areas that actually get inspected. Potable water sampling records, galley temperature logs, waste segregation and sharps handling, and rodent and vector evidence[3]. A control certificate instead of an exemption certificate means remedial measures were applied, and it invites closer attention next time.
- Keep the US duty separate in the SMS. The 42 CFR 71.21 report of death or illness before arrival at a US port is unrelated to the certificate and applies regardless of it[4].
Where this sits in a vessel medical programme
Ship sanitation is one of the layers a vessel medical programme has to hold together, and it is the one most often handed to an agent and forgotten. It sits alongside potable water and sanitation under 21 CFR part 1250, the MLC medicine chest inspection, and the controlled substances position under 21 CFR 1301.25[11].
Discovery Health MD reads a fleet’s flag, route and records and states which of these actually apply, cited to the governing rule. That work sits in our maritime medical consulting line. The chest itself is MedChest. If you want the whole picture first, start with the six decisions that set up a vessel medical programme or a compliance audit. Speak to the team.
Common questions
Do I need a ship sanitation certificate to enter a US port?
No. CDC states that it does not currently require ships to present ship sanitation certificates when calling at US ports[1]. The obligations that do attach on a US call are the 42 CFR 71.21 report of any death or ill person[4] and CDC’s inspection power under 42 CFR 71.31[5]. Foreign flag vessels calling at US ports are in the same position.
Can I renew my ship sanitation certificate in the United States?
Not if you are a cargo vessel. CDC states that cargo vessels cannot obtain a ship sanitation control or exemption certificate in the United States, and that no port authority, public agency or private organisation there is authorised to issue one[1]. The single exception is the Vessel Sanitation Program, which may issue one on request during an inspection of a cruise ship within its jurisdiction[1][6].
A US company offered to issue my certificate. Is it valid?
No. CDC’s position is explicit: “Any certificates issued by private companies in the United States are not valid.”[1] A document that is not valid is worse than no document, because it sits in the ship’s certificate file and will be checked. If you have bought one, treat the certificate as expired and plan a renewal at an authorised foreign port[3].
How long is a ship sanitation certificate valid?
Six months from issue, with a one month extension available where inspection or control measures cannot be carried out at the port[8]. The certificate is issued as an exemption certificate when no evidence of a public health risk is found, and as a control certificate when a risk was found and measures were applied[3]. That distinction follows the ship, so an exemption certificate is the outcome to plan for. The same forward planning logic applies to a change of flag state.
Does the certificate cover the medicine chest or crew health?
No. The inspection covers vessel hygiene: potable water, food handling, waste, accommodation, ballast, and vector evidence[3]. It does not examine the medicine chest, it does not check crew medical records, and it has nothing to say about controlled substances aboard. Those are separate regimes with separate inspectors.
Which vessels fall under CDC’s Vessel Sanitation Program?
Cruise ships carrying 13 or more passengers on a foreign itinerary with US ports[6], under the authority of 42 U.S.C. 264[7]. Everything outside that line is outside the programme, which includes cargo tonnage, fishing vessels, towing vessels, offshore supply vessels and research vessels. Those vessels still carry the reporting duty[4].
Who should own ship sanitation certificates in the company?
The same person who owns the rest of the medical and public health file, which under the ISM Code is the Company rather than the master[2]. We set that out in who is responsible for crew medical compliance. Handing it to a port agent is normal and sensible for the booking, but the validity risk and the invalid certificate risk stay with the operator, alongside the route specific duties the company already carries.
