COVERAGE &
METHODOLOGY

The rule count is the full rule base exactly as our database stores it, including 61 rules that fire only in EU mode — an opt-in scan setting adding 3 screening categories under EU Regulation (EC) No 1223/2009 (fragrance-allergen disclosure and Annex II/III restrictions). The requirement count is United States coverage only: obligations that can arise only in EU mode are excluded.

Rule: One named check in our rule base, counted exactly as the database stores it: every federal, state, and retailer rule, every claim pattern, every ingredient-hazard entry, and every Proposition 65 listed chemical is one rule. A single statute can contribute many rules, one per substance name it reaches, so this figure is larger than the requirement count by design.
Requirement: One obligation a label can independently fail, counted the way its own source document enumerates it: a CFR section, a state statute, one line of a retailer's published policy, one claim pattern, one ingredient-hazard category, or the Proposition 65 warning duty.
The two figures count one rule base at two grains: the Proposition 65 screen alone is 903 rules under a single warning requirement, and the ingredient-hazard table is one rule per substance name across 12 hazard categories. Every scan additionally evaluates a fixed catalog of federal, state, claims, and OTC-boundary rules (the "rules evaluated" figure on your scan results); ingredient-hazard screening and retailer program checks run on top of that catalog. The regimes covered are listed below, with the statute behind each.

How to read this table. 15 of the 20 states ban a chemical class — one encoded rule reaches every member of that chemical family in your ingredient declaration; the rest enumerate substances, screened by name.

In the remaining 30 states, federal FDA 21 CFR labeling requirements still apply and are checked on every scan. State coverage expands as legislatures act, and we add jurisdictions on request. Request a state →

Ingredient-name validation uses the European Commission's CosIng cosmetic ingredient database (ec.europa.eu/growth/tools-databases/cosing) to recognise official INCI names. © European Union, 1995–2026. Reused under Commission Decision 2011/833/EU; the European Commission does not endorse CPGShield or this use of its data. The California Proposition 65 list is published by OEHHA, and the Code of Federal Regulations is a US government edict; neither carries copyright.

Every ingredient-hazard entry is sourced from an official regulatory list (OEHHA, eCFR, state statutes and administrative codes, EUR-Lex). A line-by-line citation audit against primary sources is in progress; entries awaiting confirmation are flagged unverified in the product, with per-entry status visible in the Rule Library → Ingredient Hazards tab. Independent review by outside regulatory counsel is a separate, planned gate and has not yet occurred. Corrections: support@cpgshield.com.

CPGShield reads what is on the label. These obligations live elsewhere — your formulation file, your FDA filings, a testing lab — where no label reader can see them. Each is listed below with the route to satisfy it:
