A disinfectant sold in Canada with a claim to kill micro-organisms on a surface needs a Drug Identification Number (DIN) issued by Health Canada, or in some cases a DIN-HM for a homeopathic product, or an NPN for a natural health product. Cleaning products that make no antimicrobial claim do not need one. The label prints the number as "DIN" followed by eight digits, and a clinic checking a supplier should look for it before comparing price. For daily surface work, clinics stock a product with the number on the label, such as these disinfecting wipes, rather than a general-purpose cleaner.
This is one of the few places where the buyer, not the clinician, carries the compliance load. If a product kills organisms on a surface and has no DIN, the claim itself is the problem, and a clinic that uses it for reprocessing surfaces or equipment cannot show the inspector a valid product.
What is a DIN and which disinfectants need one?
| Product claim | Number required |
|---|---|
| Kills bacteria, viruses or fungi on a surface | DIN (Drug Identification Number) |
| Disinfects and also makes a therapeutic claim | DIN, with the claim reviewed |
| Cleans without an antimicrobial claim | None |
| Hand hygiene product making an antimicrobial claim | DIN or NPN, depending on the claim |
How do you find the DIN on a disinfectant label?
Read the back panel: the number appears as "DIN" plus eight digits, usually near the manufacturer block and the lot code. Record it with the product name in your surface-disinfection log. If two suppliers offer the same active ingredient at different prices, the DIN tells you whether you are looking at the same registered product or at a cleaner that borrowed the marketing language.
What is the difference between a DIN, a DIN-HM and an NPN?
A DIN belongs to a drug product, which is where disinfectants sit. A DIN-HM is for a homeopathic product and an NPN for a natural health product; both are also eight-digit identifiers, so read the letters, not the digits. Referencing the wrong prefix in a policy document is the kind of detail an inspector will notice.
What should a clinic record about the disinfectant it uses?
Product name, DIN, lot number, the contact time you actually allow, and the surfaces or devices it is approved for. The contact time on the label is the part clinics get wrong most often: a wipe that needs the surface to stay wet for a stated dwell time is not doing its job if it dries in half that. Pair the log with a printable template so the inspection pack is complete. Where a strength claim about the establishment itself is needed, it is stated as held registration — CliniEco holds MDEL #35334.
Make it repeatable: print the compliance log templates, use the same page as your free log generator, and ask a compliance specialist when a result is unclear.

Frequently Asked Questions
Do all disinfectants in Canada need a DIN?
A product that claims to kill micro-organisms on a surface needs a DIN. A cleaner with no antimicrobial claim does not.
How many digits does a DIN have?
A DIN is eight digits, printed after the letters DIN on the label. DIN-HM and NPN are also eight digits, so read the prefix.
Where is the DIN printed?
On the back panel near the manufacturer details and lot code.
What contact time should a clinic follow?
The dwell time printed on the label for that product and surface. Letting the surface dry early shortens disinfection.
CliniEco Medical is a licensed medical device establishment (MDEL #35334).
