Quick facts
- A boiling water sterilizer is an AC-powered container in which dental and surgical instruments are submerged in boiling water.
- In the United States it files under 21 CFR 872.6710, Boiling water sterilizer, at Class I, product code ECG.
- In Canada the device is one that is intended to sterilize a medical device, so Rule 13(b) of Schedule 1 sets Class II — a real class difference between the two countries.
- Rule 13 is a special rule that runs on the purpose of the device rather than on how it is applied, which is why the simplicity of a boiling container does not lower the class.
- The near miss is Rule 12, the residual Class I rule for active devices; Rule 13 displaces it for a device whose stated job is to sterilize other devices.

A boiling water sterilizer is the simplest article in the reprocessing room: an AC-powered container of water, a basket, and a lid, into which dental and surgical instruments are submerged and boiled. It is a sterilizer by name and by stated purpose, and that is exactly the point on which the two jurisdictions part. The United States names it at Class I; Canada reads it as a device used to sterilize medical devices and sets Class II. This article sets out both routes, with the nitrile examination gloves used through the same reprocessing bench.
What is a boiling water sterilizer?
It is an AC-powered device that consists of a container for boiling water. The device is intended to sterilize dental and surgical instruments by submersion in the boiling water in the container. The article is deliberately simple: a heated vessel, a basket to keep the instruments off the base, and a cover, with the water brought to a boil and the load held under it for the time the maker states.
The devices that go into it are the small, solid, unwrapped metal instruments of a dental or minor-surgical tray. The unit's stated job is to sterilize them; whether a given load reaches a particular sterility assurance level on a given cycle is a question for the maker's instructions and the practice's validation, not for the class entry. What the class entry records is the purpose the device is sold for.
What class is a boiling water sterilizer in the United States?
It is a named entry at Class I. 21 CFR 872.6710 is titled Boiling water sterilizer, and the identification reads: "A boiling water sterilizer is an AC-powered device that consists of a container for boiling water. The device is intended to sterilize dental and surgical instruments by submersion in the boiling water in the container." The entry sets the class at Class I (general controls).
The openFDA device classification API lists product code ECG against 872.6710. The American treatment is built on the article itself: a container of boiling water is a low-risk object, and the entry names it and fixes the class at general controls. The striking comparison inside the same subpart is the endodontic dry heat sterilizer, which carries a Class III entry — the class of a sterilizer in the American scheme follows the particular article rather than the purpose it serves.

| Neighbour in the same subpart | Endodontic dry heat sterilizer, 21 CFR 872.6730, a Class III entry |
How does Canada classify a boiling water sterilizer?
Canada keeps no named entry. It applies the classification rules in Schedule 1 of the Medical Devices Regulations, and the rule that governs this device is a special rule that runs on purpose rather than on the shape of the article. Rule 13 reads: "A medical device that is intended to be used for (a) disinfecting or sterilizing blood, tissues or organs that are intended for transfusion or transplantation is classified as Class IV; and (b) disinfecting or sterilizing a medical device is classified as Class II."
The identification puts this device squarely inside limb (b): it is intended to sterilize dental and surgical instruments, which are medical devices. The class is therefore Class II, whether the unit is a simple boiling container or a tabletop autoclave. Rule 12, the residual rule for other active devices, is the near miss; it would give Class I, and it is displaced because Rule 13 reaches a device with this stated purpose first.
| Item | Canada | United States |
|---|---|---|
| Named entry | None; classified by rule | 872.6710 - Boiling water sterilizer |
| Class | Class II (Rule 13(b), device used to sterilize a medical device) | Class I (general controls) |
| Governing text | Schedule 1, Part 1, Rule 13(b) | 21 CFR 872.6710 |
| Near miss | Rule 12 would give Class I to an active device not reached earlier | Not applicable |
| Class III neighbour | Rule 13(a) applies only to blood, tissues or organs for transfusion or transplantation | Endodontic dry heat sterilizer 872.6730 is Class III |
Why does Canada classify by purpose while the United States classifies by article?
Because the two schemes are built in different orders. The American scheme works through a long list of named articles, each with its own class, so a boiling water sterilizer and a dry heat sterilizer can sit in the same subpart with very different classes. The Canadian rules ask first what the device is for; a device whose stated job is to sterilize another medical device is placed by that purpose, whatever the device is made of.
The practical result is a genuine class difference on the same article: Class I in the United States and Class II in Canada. It is a good reminder that a device can be simple and still carry a real obligation in one of the two markets, and that the class is a statement about the role the device is sold to play rather than about how much hardware it contains.
What should a practice check before buying one?
Four checks. First, confirm what the maker says the unit does and on which instrument types, because the class entry in both countries turns on the stated purpose and the load the unit is built for. Second, confirm the cycle time and the temperature the maker specifies, and whether the unit monitors them or merely heats. Third, confirm the maker's guidance on water quality and on the cleaning of the chamber, since scale and residue are the usual reason a boiling unit underperforms. Fourth, confirm the documentation the maker holds in each market, because the same unit carries a Class I entry in the United States and a Class II obligation in Canada.
A dental practice also restocks the bench disposables used through the reprocessing area. Clinics that stock for a whole practice can order through the wholesale programme and request a bulk quote for a standing or annual order; the nitrile examination gloves sits in the same catalogue. Consumables for this line are listed under dental practices. Reselling? become a distributor.
How does the class affect what the practice records?
The class sets the market-entry path; the record is set by the practice's own infection-control routine and by the maker's instructions. A reprocessing cycle is logged with the date, the cycle, the temperature or the indication, the load and the operator, so the record shows the cycle was run the way the maker intended.
That is true of a boiling unit exactly as it is of an autoclave. What the Canadian Class II reading adds is not a second set of records; it is a different piece of evidence the maker has to hold, and therefore a different document a practice can ask a supplier to produce before it puts the unit into service.

A printable reprocessing cycle sheet. Date, cycle, load and the person who ran it are the four columns any sterilizer log needs, whether the unit is a boiling bath or a vacuum autoclave. The compliance log centre holds a blank sterilization log you can print and clip beside the unit — no account and no sign-up, and you can print a fresh one each month.
Label the unit once, then print the runs. Enter the practice name, the sterilizer and the cycle type, and the sterilization log generator returns a dated sheet ready to print or file straight into the quality manual.
Ask a compliance specialist. A classification question usually turns on how the device is used, not only on its name. Ask a compliance specialist — you get a written answer specific to your equipment and province, with the regulation or standard it is based on cited.

Frequently Asked Questions
What class is a boiling water sterilizer in the United States?
Class I under 21 CFR 872.6710, product code ECG, an AC-powered container for boiling water into which instruments are submerged.
What class is it in Canada?
Class II. Rule 13(b) of Schedule 1 classifies a device intended to disinfect or sterilize a medical device as Class II, and the identification states that this device is intended to sterilize dental and surgical instruments.
Do the two countries disagree?
Yes — this is a real class difference. The United States names the article at Class I; Canada classifies by the purpose the device is sold to serve and sets Class II.
Why is a simple container not Class I in Canada?
Because Rule 13 keys on what the device is for rather than on how complex it is. A device whose stated job is to sterilize another medical device is placed by that purpose.
Does Rule 12 not apply instead?
Rule 12 is the residual rule for active devices that no earlier rule reaches. Rule 13 reaches a device intended to sterilize a medical device, so it governs first.
What should the practice log for each cycle?
The date, the cycle, the temperature or the cycle indication, the load and the person who ran it, so the record shows the cycle was run as the maker intended.
