The Prop 65 Warning & Notice-Defense Engine assembles a documentation-complete warning determination or 60-day notice defense pack — every statutory element, every required exposure assessment, the enforcer matrix, the evidence log, and the safe-harbor checklist — checked against the letter of California Health & Safety Code §25249.6 and OEHHA regulations before a specialist releases it.
A consumer brand's Prop 65 defense is only as strong as the evidence behind it. Miss one of the five statutory notice elements, skip a required exposure assessment, mis-time the 60-day window, or fail to document a safe-harbor threshold — and the notice can become a lawsuit, a settlement, or a judgment that exposes the brand to crippling liability.
Most brands run this by hand, from memory, once or twice a year. The statute has not been read end-to-end since the last time it mattered. That is exactly where completeness gaps hide.
The Prop 65 Warning & Notice-Defense Engine exists to close that gap with a single, exhaustive standard applied identically to every file.
We do not summarize the law and hope. Every pack is scored against a versioned rule pack tied to the exact text of Cal. Health & Safety Code §25249.6 and OEHHA regulations. These are the provisions each pack is held to.
The warning must be 'clear and reasonable' — meaning it must name at least one listed chemical per endpoint, be prominently displayed, and meet OEHHA safe-harbor content requirements. Every pack is checked against the current safe-harbor regulations.
No warning is required if the exposure is below the No Significant Risk Level (NSRL) for carcinogens or the Maximum Allowable Dose Level (MADL) for reproductive toxicants. The pack must include a documented exposure assessment or a basis for exemption.
Upon receiving a 60-day notice, the pack must assemble a defense evidence file: defective-notice challenges, statute-of-limitations analysis, and above all the 'no warning required because exposure is below safe-harbor level' evidence.
The pack must verify that any warning label or content complies with OEHHA's safe-harbor regulations, including the 2024 amendments requiring at least one named chemical per endpoint and a three-year transition to the new short-form format.
The exposure assessment must follow OEHHA's methodology for calculating daily exposure levels and comparing them to NSRLs and MADLs. The pack documents the methodology and data sources.
The pack includes a penalty exposure analysis based on the number of days of violation and the number of violations, and documents the basis for any settlement or dismissal recommendation.
AI extracts and drafts. Deterministic rules — running as code, outside the model — decide what is complete. A human specialist signs every release. That order is never reversed.
Upload your product SKU list, SDS, ingredient data, or lab reports. We return a free completeness read: which statutory elements and exposure assessments you already have, and which are missing.
As your authorized clerical agent, we collect supplier ingredient data, order lab testing if needed, and build the exposure assessment comparing daily intake to NSRLs and MADLs.
The warning determination or notice-defense pack is drafted from your validated data and the §25249.6 rule pack into field-locked templates — no legal opinions, no invented facts.
Exposure levels reconcile to the data to the microgram; the safe-harbor threshold is verified; the enforcer matrix is resolved; SCRA is screened. Any failure blocks release.
A California attorney and a board-certified toxicologist review the exception queue and sign the release. High-exposure or novel chemical matters route to additional expert review.
You receive the pack: determination or defense evidence file, exposure assessment, enforcer matrix, evidence log, safe-harbor checklist, and the 60-day calendar — ready for your legal team to use.
The deliverable is completeness itself — every statutory element and exposure assessment accounted for or explicitly exception-coded. Nothing is left implicit.
The gates that decide completeness are code, not a model's opinion. A drafting error cannot slip past a statutory requirement.
We prepare documentation and run assessments as your clerical agent. We never contact the enforcer, give legal advice, or conduct the litigation.
Simple, predictable, and aligned with a documentation standard — not a cut of any settlement.
Start with a free Exposure Gap Scan. Send your product SKU list, SDS, or ingredient data and we'll return a completeness read against every subsection of §25249.6.
