Tools - Echa´s IUCLID 6
The industry-standard data management tool for regulatory chemical information.

Echa IUCLID 6 is the industry-standard data management tool for regulatory chemical information — mandatory for compliance under EU and many international chemical safety regulations. 4chems runs it for you as a managed service: in a dedicated, isolated environment in EU data centres, always on the current ECHA release, with the integrations around it that the free software does not give you.
What 4chems adds
- Keeping up with ECHA releases — before: your own migration project, often leaving you a version behind → with 4chems: we apply every release within days (from 48 h), usually over a weekend. You get: the current IUCLID format without migration pain.
- Finding errors before ECHA does — before: hidden validation errors surface only when the dossier is returned → with 4chems: the IUCLID AI-Assistant Observer surfaces them before you submit. You get: fewer last-minute fixes and fewer returned dossiers.
- Working with heavy dossiers — before: ordinary hosting slows down or crashes during upload and processing → with 4chems: hosting built for large dossiers. You get: a 21 GB dossier loaded in hours, not days.
- Submitting to REACH-IT — before: manual .i6z export and upload, with room for human error → with 4chems: system-to-system submission via API. You get: dossiers delivered to REACH-IT without the manual step.
- Running the platform safely — before: servers, backups and security are yours to maintain → with 4chems: dedicated isolated environment, automated backups and disaster recovery, ISO 27001-certified EU data centres, professional support with a fast first response. You get: a GDPR-compliant service where we act as data processor and you keep full ownership and export rights to your data.
