We've been in business for years, with safety data sheets, labels, and ISK registrations all in order. Why do we now have to deal with UFI and PCN?

The question is entirely logical. And fair. Companies have organized safety data sheets, labels, ISK registrations. The system works. So why the additional requirement?

The answer is simple: UFI and PCN were not created for companies, but for doctors and poison centers. And this is where the essence begins.

What is UFI and why is it used?

UFI is a 16-character code. By itself, it doesn't convey anything. It has no meaning. It's merely an identification key. The true significance lies in the PCN dossier linked to this code.

When someone comes into contact with a hazardous mixture—at home, in a workshop, or in industry—a doctor doesn't search for the trade name, read the safety data sheet, or guess whether it's an old or new version of the product. They enter the UFI into the system and instantly receive accurate information about the composition and recommended medical actions.

Why can't this be solved with just a safety data sheet?

Because:

• trade names are not unique,
• packaging circulates in different languages,
• safety data sheets change and get updated,
• in emergencies, minutes count, not explanations.

PCN is therefore a separate database managed by ECHA, and it is not a replacement for the ISK database. It is an additional layer of safety—intended solely for quick and correct action in the event of an accident with a hazardous chemical.

Practical lesson:

UFI and PCN are submitted precisely by country. If your product has a UFI and PCN that has not been submitted for Slovenia, the product is still not suitable for market placement in Slovenia. And that is exactly what the inspector checks in the first step.
