Pre-Flight Validation — Bad Data Cannot Reach The Authority
Every substance row is checked while you type. A report cannot be generated with a blocking error outstanding.
- ▪ Check-digit arithmetic on every CAS and EC / List number — not just the digit pattern. A wrong digit is rejected and the correct one is offered as a one-click fix.
- ▪ Around 60 ECHA hazard statements, auto-matched from the CLP hazard classes you select, searchable by code or wording.
- ▪ Advisory flags when your hazard data implies a different Seveso III Annex I category than the one selected, with the suggested category applied in one click.
- ▪ Blocking errors and advisory warnings listed separately, so you always know what stops the report and what is only a caution.
Why Pay For CHEMPAC?
Built for chemical operators who cannot afford a bad submission.
- Stop invalid reports before they reach the authority — live CAS and EC check-digit validation, CLP-to-Seveso consistency flags, and blocking errors that prevent generation until fixed.
- Replace spreadsheets with a permanent audit trail — every report is archived and re-downloadable; the Audit-Ready Bundle includes raw CSV plus a SHA-256 verification hash.
- Save hours of manual cross-checking — automatic Σ(q/Q) Seveso III summation against Annex I thresholds, ECHA hazard-statement matching, and a 120+ substance library with autocomplete.
- One-time fee, no subscription lock-in — pay €89 per standard report or €299 for the Audit-Ready Bundle; no recurring seat licenses.
- Built specifically for EU regulatory language — SEVESO III, REACH, CLP, and national competent-authority submission formats, not a generic US Tier II template.

Mandatory Legal Notice — ECHA / SEVESO III / REACH
LEGAL NOTICE: CHEMPAC INVENTORY SYSTEM formats operator-provided data into a standardised European hazardous substance inventory layout for informational and internal record-keeping purposes. It does not constitute legal, environmental, or regulatory certification, and it does not file anything on your behalf. Quantities, CLP classifications, and Seveso III (Directive 2012/18/EU) qualifying quantities must be verified against ECHA guidance, Regulation (EC) No 1907/2006 (REACH), Regulation (EC) No 1272/2008 (CLP), and the applicable national implementing legislation. The operator is solely responsible for submitting this inventory to its national competent authority.
