PCN software: how to choose a poison centre notification tool

“Best PCN software” has no single answer, because the market holds three kinds of product solving three different problems, and one of them is ECHA’s own, at no charge. This page maps the three, gives you the evaluation questions that separate tools, and says where each category stops being the right buy.

The three categories

Enterprise EHS suites

Platforms in the Sphera, Lisam and EcoOnline class treat PCN as one module in a broad compliance product: SDS authoring in up to 50 languages, label generation, regulatory content libraries, ERP integration. Licences are quoted by scope as an annual contract, and implementations take weeks to months. Judged as PCN software alone, that looks expensive. Judged as a platform, it’s coherent. The suite is the right category when PCN is one line in a longer requirements list.

The free stack: IUCLID and the ECHA portal

ECHA’s own tooling is a complete path at no charge: prepare the dossier in IUCLID Cloud online or in IUCLID 6 on the desktop, then submit through the portal, or connect system-to-system with ECHA-issued keys. It produces the same .i6z dossier any paid tool does, and for a one-off single mixture it’s the right answer. The cost is your time: the interface assumes you know the regulation, the EuPCS has roughly 250 categories to choose from, and the validation layer enforces more than 130 blocking business rules. The step-by-step route is in how to submit a PCN.

Focused submission tools

The third category does one job (composition in, valid submission out) and charges per dossier rather than per seat. UFI Number is an example: charged per notification, built to create the UFI, prepare the notification in the current required format and send it through ECHA’s official system-to-system route under your own legal entity. It’s in private beta. The boundary: focused tools don’t do CLP classification and don’t author safety data sheets. They assume your data is right and take the submission mechanics off your hands.

The mismatch is structural. Cefic counts roughly 31,000 chemical companies in the EU. 97% of them are SMEs. The suites were built for a bigger buyer than that, and the free stack assumes you already know the regulation. That’s why a suite feels oversized to a 15-mixture formulator, why the free stack feels underpowered to anyone submitting monthly, and why the focused-tool category exists at all.

An evaluation checklist that separates tools

Feature lists in this market blur together. These eight questions don’t:

• Does it submit, or only build files? Some tools stop at generating an .i6z you must upload to the portal yourself; others submit system-to-system and return the submission number. The difference is a manual step per dossier, per update, every time.
• Who tracks format versions? ECHA updates the PCN format roughly annually. Version 8 has been current since April 2026. Ask: when the format changes, what do I have to do? The answers range from “nothing” to “install an upgrade and migrate”. Background in PCN format versions.
• Is UFI generation built in? If not, you keep a parallel process with ECHA’s generator and copy codes between systems. It works, but every copied code is a chance to mistype it. How the algorithm works is in how to generate a UFI.
• Can it handle mixture-in-mixture? If you buy intermediates, your portfolio has them. A tool that can’t reference a supplier’s UFI or handle the MiM rules forces workarounds where the data is hardest.
• Does it track per-country reception? Six member states require confirmation of receipt before market placement, and two accept submissions they aren’t yet ready to receive. If you sell in several countries, per-country status matters; see the country guides.
• What audit trail do you keep? Submission numbers, timestamps, dossier copies, validation reports: what an inspector asks for. In ECHA’s 2025 enforcement pilot (ECHA/NR/26/08), inspectors in 18 EU/EEA countries checked 1,597 mixtures. A targeted enforcement project, not a measure of the whole market. The record needs to be there on request, not rebuilt. Check that it survives staff changes and, if you ever leave the tool, comes with you.
• How is it charged? Per seat or per year suits high volumes and many users; per dossier suits an SME portfolio where volume is lumpy. Work out both against your own mixture count before comparing vendors.
• Can you get your data out? Compositions, formulation numbers and dossier archives are yours. A tool without export is a tool with a hostage.

Honest fit boundaries

Where each category stops being the right buy:

• One mixture, once: use ECHA’s portal. It’s official, it’s enough, and it costs nothing. Software for a single dossier is hard to justify.
• SDS authoring in many languages, ERP integration, global coverage: that’s an enterprise suite, and a focused tool won’t get you there.
• Tens of mixtures, known compositions, standard hazards: a focused tool wins on cost and time; a suite is more than you need, and doing it yourself is slow at that volume.
• Uncertain classification or missing data: no software in any category fixes this. It’s consultant or laboratory work first, submission second. See do I need a consultant for PCN.
