# Custom SDS

> Custom SDS turns a chemical identifier — a CAS number, chemical name
> or formula — into a source-linked draft Safety Data Sheet or a print-ready GHS
> Label, in OSHA 29 CFR 1910.1200 and CLP EC 1272/2008 format, for $5 per
> document. Guest checkout, no account, editable .docx and PDF, delivered in

## What it is

- A 16-section draft SDS assembled from named public sources (PubChem, NIST,
  EPA, ECHA C&L, EU CLP Annex VI), white-labeled with the buyer's own company
  details in Section 1.
- A GHS Label with the correct pictograms, signal word, hazard and precautionary
  statements for the substance.
- A free preview of Sections 1, 2 and 9 for any compound, before payment.
- A Custom SDS from a structural proxy for unlisted compounds, using structurally
  similar reference compounds scored by Tanimoto similarity, with the read-across
  rationale disclosed in Section 11 per ECHA RAAF guidance and every page
  watermarked "Research/Developmental Use Only".
- An API for teams generating at volume.

## What it is not

- Not a certification, approval or audit pass. Every document is a draft for
  review by a qualified EHS professional, and it says so on the document.
- Not a library of existing manufacturer sheets: it authors the sheet for a
  formulation nobody has published.
- Not model-invented data. Safety-critical values carry a named source
  reference; model-inferred values are held as inference candidates and a
  complexity gate refuses a compound rather than guessing at it.

## Pricing

- $5 per document (SDS, GHS Label, or the SDS + GHS Label bundle).
- Pro at $99 per month for volume, Custom SDS and API access.
- Enterprise at $1,000 per month.
