PCN software: how to choose a poison centre notification tool

“Best PCN software” has no single answer, because the market contains three different kinds of product solving three different problems — and one of them is free and official. This page maps the categories factually, then gives you the evaluation questions that actually separate tools, and states plainly 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 run on the order of €5,000–60,000 per year, and implementations are measured in weeks to months. Judged as PCN software alone that looks expensive; judged as a platform purchase it is 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, free path: 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 is genuinely the right answer. The cost is your time: the interface assumes regulatory familiarity, 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 prices per dossier rather than per seat. Ufi Number is an example: €20 per mixture on prepaid credits, UFI generation built in, dossier built in the current required format and submitted system-to-system under your own legal entity. The honest boundary: focused tools do not do CLP classification and do not author safety data sheets. They assume your data is right and make the submission mechanics fast.

The category-mismatch problem is structural. Cefic counts roughly 31,000 chemical companies in the EU, 97% of them SMEs — yet most PCN-capable software was originally designed for the other 3% and sold downmarket. That is why the suites feel 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: neither of the older categories was built with the median duty holder in mind.

An evaluation checklist that actually discriminates

Feature lists in this market blur together. These eight questions do not:

• 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 automatically. The difference is a manual step per dossier, per update, forever.
• Who tracks format versions?ECHA updates the PCN format roughly annually — version 8 has been current since April 2026. Ask directly: when the format changes, what do you have to do? The honest answers range from “nothing” to “install an upgrade and migrate”. Background in PCN format versions.
• Is UFI generation built in?If not, you maintain a parallel process with ECHA’s generator and copy codes between systems — workable, but a transcription-error surface. How the algorithm works is covered in how to generate a UFI.
• Can it handle mixture-in-mixture?Most real portfolios contain purchased intermediates. A tool that cannot reference a supplier’s UFI or handle the MiM rules forces workarounds exactly 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 are not 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. Enforcement is active: inspectors in 18 EU/EEA countries checked 1,597 mixtures in the 2025 pilot project, so the record needs to be producible on request, not reconstructed. Check that it survives staff changes and, if you ever leave the tool, comes with you.
• How is it priced? Per seat or per year suits high volumes and many users; per dossier suits SME portfolios where volume is lumpy. Compute both models against your actual 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, stated without hedging:

• One mixture, once:use ECHA’s portal. It is free, official and sufficient; buying software for a single dossier rarely pays back.
• SDS authoring in many languages, ERP integration, global coverage: that is an enterprise suite, and a focused tool will not get you there.
• Tens of mixtures, known compositions, standard hazards: a focused tool wins on cost and speed; a suite is overbuy and DIY is slow at that volume.
• Uncertain classification or missing data: no software in any category fixes this — it is consultant or laboratory work first, submission second. See do I need a consultant for PCN.

The buying decision compresses to one sentence: pick the free stack for one-offs, a focused tool when the problem is throughput, a suite when the problem is bigger than PCN — and price every option against the recurring work, not the first dossier.
