The short version of what people ask us most — about the free library, the plans, and what the authoring engine will and won't claim. Anything else, write to us.
Yes. The Free plan stores up to 200 SDSs with unlimited viewers and a distribution portal — free forever. When paid plans open, Starter ($15/mo) removes the storage cap.
Anyone who just reads a sheet, scans a QR code, or reprints a label. Viewers are free and unlimited on every plan — you only ever pay for locations and authoring seats.
No. Scanning a container QR code or opening your portal link goes straight to the current sheet — no login, no seat, no app.
Yes. The library hosts the sheets you already have from your suppliers — authoring is only for sheets you create yourself.
Soon. Hosting and reading are free today; join the waitlist and we'll email you the moment paid plans are available.
Two months — annual plans are priced at ten months (e.g. Starter is $15/mo or $150/yr).
Yes — one-off SDS authoring is $49 per SDS, no subscription required.
Multi-Site and Author Plus include 5 locations (+$10/site each beyond that). Past that, Enterprise offers unlimited locations at a per-site rate, plus SSO, an SLA, API access, and dedicated onboarding — contact us.
The U.S. OSHA Hazard Communication Standard (29 CFR 1910.1200) as updated by the May 2024 final rule. We do not currently produce SDSs valid in the EU, UK, Canada, or other GHS jurisdictions — details in the methodology.
From first principles under the GHS rule set adopted by HCS 2024 — ATE additivity, concentration cutoffs and SCLs, and the summation method — with an audit-trail calculation string on every result. The methodology covers each endpoint.
Every classification is stamped with the engine version that produced it. Published sheets are re-checked against the current engine and flagged if a newer rule set would change the result.
The Author Plus plan includes PDF + Word export and version history, so every sheet you publish is yours to file, print, and archive.
Send us the question — it lands with a person, not a ticket queue.
