Step 1: Identify Product Category

Category	Key Regulations	Substance Databases
Cosmetics	EU 1223/2009, FDA MoCRA, UK Cosmetics Reg, Health Canada NHP, Japan SLR, Korea MFDS	CosIng, FDA VCRP, Prop 65, ECHA SVHC
Food & Supplements	EU 2015/2283, FDA DSHEA, EFSA, Codex Alimentarius	FDA GRAS, EFSA Novel Food, Prop 65
Electronics	RoHS, WEEE, FCC Part 15, CE/LVD, UKCA, EN 62368	RoHS substance list, REACH SVHC
Toys	EN 71, CPSIA, ASTM F963, EU 2009/48	EN 71-3 migration limits, CPSIA lead/phthalate
Textiles	REACH, OEKO-TEX, EU Ecolabel, CPSIA (children)	REACH SVHC, ZDHC MRSL, Prop 65
Cleaning products	EU CLP, EPA, REACH, Biocidal Products Reg	CLP classification, ECHA SVHC
Medical devices	EU MDR 2017/745, FDA 510(k), UKCA MDR	Biocompatibility (ISO 10993)
General consumer	EU GPSR 2023/988, CPSC, UK Product Safety	RAPEX alerts, CPSC recalls

Step 2: Resolve CAS Numbers

For each ingredient:

1. User provides INCI name, trade name, or CAS number
2. If INCI name: map to CAS using CosIng database or PubChem
3. If trade name: identify active substances, get CAS for each
4. If mixture: break down to individual substances with concentrations

Critical: One trade name ingredient can contain multiple regulated substances. Always decompose.

Step 3: Check Against 13 Substance Databases

#	Database	Scope	What it tells you
1	CosIng (EU)	EU cosmetics	Banned (Annex II), restricted with limits (Annex III), allowed colorants (Annex IV), allowed preservatives (Annex V)
2	ECHA SVHC	EU all products	Substances of Very High Concern; if >0.1% w/w, must notify ECHA and inform buyers
3	REACH Annex XVII	EU all products	Restrictions on manufacture, sale, use; substance-specific conditions
4	California Prop 65	US California	Known carcinogens/reproductive toxins; requires warning label if present above safe harbor level
5	FDA (cosmetics)	US cosmetics	Prohibited/restricted ingredients under MoCRA; color additive approvals
6	FDA GRAS	US food	Generally Recognized As Safe; absence = may need food additive petition
7	EFSA	EU food	Novel food status, health claims, additive approvals
8	Health Canada	Canada	Cosmetic Ingredient Hotlist (prohibited/restricted), NHP ingredient database
9	Japan Standards	Japan	Positive list (cosmetics), Standards of Labeling for Allergenic Substances (food)
10	Korea MFDS	Korea	Functional cosmetic ingredient restrictions, CGMP requirements
11	UK post-Brexit	UK	UK REACH, UK Cosmetics Reg (mirrors EU but diverging), UKCA
12	RoHS substances	EU/UK/CN electronics	10 restricted substances with max concentration limits
13	CPSIA	US children's products	Lead (100ppm), phthalates (8 restricted), third-party testing required

Using MCP Tools

# If Cleo Legal API is available:
mcp__claude_ai_CLEO_LEGAL_API__compliance/check
  product_description: "face moisturizer"
  ingredients: ["water", "glycerin", "niacinamide", "retinol"]
  target_markets: ["EU", "US", "UK"]
# Returns: per-ingredient, per-market compliance status

# Cross-reference with Cleo Insight for recent changes:
mcp__claude_ai_Cleo_Insight__search_signals
  product_id: "<product-id>"
  risk_level: "critical"
# Check if any substance was recently banned or restricted

Without MCP

Use WebSearch against official sources: EUR-Lex, FDA database, ECHA, CosIng. Structure findings in the same verdict format below.

Step 4: Verdict System

Each substance gets a verdict per jurisdiction:

Verdict	Meaning	Visual	Action Required
COMPLIANT	Meets all limits in this jurisdiction	GREEN	None
FLAG	Close to threshold, data incomplete, or warning label needed	ORANGE	Retest concentration, check recent amendments, add safety margin to formulation
FAIL	Exceeds limit, banned substance, or missing approval	RED	Cannot sell. Reformulate, get exemption, or drop this market
NEEDS_REVIEW	Confidence < 0.5, conflicting sources, or no data found	YELLOW	Manual expert review required before any decision

Verdict Output Format

PRODUCT COMPLIANCE CHECK -- [Product Name] -- [Date]

Product: [name]
Category: [cosmetics / food / electronics / ...]
Ingredients: [count]
Markets checked: [EU, US, UK, CA, JP, KR]

SUBSTANCE MATRIX:
| Ingredient | CAS | EU | US | US-CA | UK | CA | JP | KR |
|------------|-----|----|----|-------|----|----|----|-----|
| Retinol | 68-26-8 | FLAG | COMPLIANT | FLAG | FLAG | COMPLIANT | FLAG | COMPLIANT |
| CBD | 13956-29-1 | FAIL | FLAG | FAIL | FAIL | FLAG | FAIL | FAIL |
| Niacinamide | 98-92-0 | COMPLIANT | COMPLIANT | COMPLIANT | COMPLIANT | COMPLIANT | COMPLIANT | COMPLIANT |

DETAILS (non-COMPLIANT only):
- Retinol / EU: Restricted under 1223/2009 Annex III entry 223a. Max 0.3% in face, 0.05% in body (new 2025 limits). FLAG -- verify concentration.
- CBD / EU: Novel food if ingested. Cosmetics: not in Annex II but EFSA safety assessment pending. FAIL -- no clear path to market currently.
- Retinol / US-CA: Prop 65 listed (reproductive toxin). Requires warning if above safe harbor. FLAG -- check concentration vs NSRL.

MARKET SUMMARY:
| Market | COMPLIANT | FLAG | FAIL | NEEDS_REVIEW | Verdict |
|--------|-----------|------|------|-------------|---------|
| EU | 1 | 1 | 1 | 0 | BLOCKED -- CBD |
| US | 2 | 0 | 0 | 1 | REVIEW NEEDED |
| US-CA | 1 | 1 | 1 | 0 | BLOCKED -- CBD |
| UK | 1 | 1 | 1 | 0 | BLOCKED -- CBD |

Step 5: Revenue-at-Risk (RAR)

RAR(product, market) = trailing_90d_sales(product, market)
  WHERE verdict = FAIL
  AND regulation.status = in_force OR effective_within_180d

Rules:

• Each (product, market) pair counted once regardless of how many substances fail
• Use trailing 90-day sales only, not projections
• If no sales data: estimate from market size and product category benchmarks
• Confidence >= 0.5 gate on all verdicts feeding into RAR

REVENUE AT RISK:
| Product | Market | 90d Sales | Failing Substances | RAR |
|---------|--------|-----------|-------------------|------|
| Face Cream | EU | EUR 45,000 | CBD | EUR 45,000 |
| Face Cream | US-CA | USD 12,000 | CBD | USD 12,000 |
| Face Cream | US (excl. CA) | USD 28,000 | -- | USD 0 |
Total RAR: EUR 45,000 + USD 12,000 = ~EUR 56,000

Multi-Jurisdiction Quick Checks

For common product types, here are the key differences:

Cosmetics: EU vs US vs UK

Requirement	EU	US	UK
Pre-market registration	CPNP notification required	FDA registration (MoCRA, mandatory from 2024)	UK SCPN notification
Safety assessment	Mandatory CPSR by qualified assessor	Manufacturer responsibility; FDA can request	Mandatory (same as EU for now)
Banned substances	1,698 in Annex II	~30 prohibited; MoCRA expanding	Mirrors EU (diverging post-Brexit)
Animal testing	Banned (including for ingredients)	Not required but not banned	Banned (mirrors EU)
Responsible person	Required, must be in EU	US agent for foreign firms	Required, must be in UK
Labeling language	Official language of country of sale	English	English

Electronics: EU vs US

Requirement	EU	US
Safety mark	CE marking (LVD + EMC)	FCC (EMC), UL/NRTL (safety, voluntary but de facto required)
Substance restrictions	RoHS (10 substances)	No federal RoHS; some state laws
Waste	WEEE (producer registration + take-back)	State-level e-waste laws
Battery	EU Battery Regulation 2023/1542	State-level (CA, NY)
Radio	RED (Radio Equipment Directive)	FCC Part 15

Common Mistakes

• Checking only one market: EU/US/UK have different banned substance lists. Always check per jurisdiction.
• Ignoring Prop 65: Applies to any product sold in California, not just "California products." Most US e-commerce = exposed.
• Missing SVHC notification: If any substance is on the SVHC Candidate List at >0.1% w/w, you must notify ECHA within 6 months and inform downstream users. This applies to articles, not just chemicals.
• Assuming UK = EU: Post-Brexit divergence is real and increasing. UK REACH has its own substance evaluations.
• Trade name vs substance: "Parfum" or "Fragrance" can contain 100+ individual substances. Get the IFRA certificate for full breakdown.
• Concentration assumptions: A substance may be compliant at 0.1% but banned at 0.5%. Always verify actual concentration against the specific limit.
• Ignoring transition periods: New restrictions often have 12-18 month transition periods. Check effective date, not publication date.
