# Packaging Copy Validator ## Overview This skill validates all text appearing on physical packaging and its digital representation (e-commerce product images, digital shelf renderings) against a comprehensive matrix of legal, regulatory, marketing, and retailer requirements. Packaging errors are among the most costly content mistakes in CPG — a single labeling non-compliance can trigger product recalls, import holds, and retailer fines. The validator treats packaging copy as a legal document that also serves as a marketing asset, applying both compliance rigor and brand effectiveness criteria. ## When to Use - Reviewing packaging artwork proofs before print production. - Validating digital shelf images and enhanced content for marketplace compliance. - Auditing existing packaging for regulatory changes (e.g., updated FDA nutrition label rules). - Preparing packaging for new market entry with different labeling requirements. - Checking private label / co-manufacturing packaging specifications. - Updating packaging after formulation changes, claim additions, or rebrand. ## Required Inputs | Input | Description | Example | |---|---|---| | `packaging_copy` | All text from the packaging (structured by panel) | `{ "PDP_front": "...", "info_panel": "...", "back_panel": "..." }` | | `product_category` | FDA product classification | "conventional food", "dietary supplement", "OTC drug", "cosmetic" | | `ingredient_list` | Complete ingredient statement | Ordered list by predominance | | `nutrition_facts` | Nutrition / supplement facts panel data | Structured nutritional data | | `net_contents` | Product quantity and unit of measure | "12 oz (340g)" | | `allergen_info` | Allergen declarations | "Contains: milk, soy, wheat" | | `target_markets` | Countries/states of sale | `["US", "CA", "EU"]` | | `certifications` | Active certifications and their logo usage guidelines | `["USDA Organic", "Fair Trade Certified"]` | | `claims` | All on-pack claims (front and back panel) | List of claim strings | | `upc_gtin` | Product barcode information | "0-12345-67890-5" | ## Methodology ### Step 1 — Panel-by-Panel Inventory Map every text element on the packaging to its regulatory classification: | Panel | Required Elements | Common Errors | |---|---|---| | **Principal Display Panel (PDP)** | Product identity statement, net quantity, brand name | Missing net quantity, identity statement not in required type size | | **Information Panel** | Ingredient statement, nutrition facts, allergen declaration, manufacturer info | Ingredient order errors, missing sub-ingredients, allergen formatting | | **Back/Side Panel** | Directions for use, warnings, storage instructions, UPC | Missing required warnings, incorrect UPC check digit | | **Top/Bottom** | Lot code, expiration/best-by date, country of origin | Missing date format, ambiguous lot coding | ### Step 2 — Regulatory Compliance Validation **FDA Labeling Requirements (21 CFR 101)**: 1. **Statement of Identity**: Common/usual name of food in bold type on PDP, parallel to base. Type size per 21 CFR 101.3. 2. **Net Quantity of Contents**: Lower 30% of PDP, in both metric and US customary units. Minimum type size per container size (21 CFR 101.7). 3. **Ingredient Statement**: Listed in descending order of predominance by weight. Sub-ingredients in parentheses. Color additives by specific name. 4. **Nutrition Facts Panel**: Current format per 21 CFR 101.9. Serving size per RACC. Updated dual-column format for packages 1-2 servings. 5. **Allergen Declaration**: Big 9 allergens (milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, sesame) declared per FALCPA + FASTER Act. 6. **Manufacturer/Distributor**: Name and address of manufacturer, packer, or distributor. "Manufactured for" or "Distributed by" language. **Supplement-Specific (DSHEA)**: - Supplement Facts panel format (not Nutrition Facts). - DSHEA disclaimer required for structure/function claims. - "Dietary Supplement" must appear on PDP. **State-Level Requirements**: - California Prop 65 warnings for applicable products. - State-specific deposit/recycling marks (CA CRV, MI, OR, etc.). ### Step 3 — Claims Validation on Packaging Cross-reference all on-pack claims against the approved claims library: | Claim Category | Validation Rule | |---|---| | Nutrient Content Claims | Must meet defined thresholds (21 CFR 101.13, 101.54-101.67) | | Health Claims | Must be FDA-authorized or qualified with prescribed disclaimer | | Structure/Function | Requires DSHEA disclaimer and 30-day FDA notification | | Organic | USDA Organic seal use per NOP; ingredient percentage thresholds | | Non-GMO | Non-GMO Project Verified requires active enrollment | | Kosher/Halal | Active certification from recognized authority; correct symbol | | Free-From Claims | "Gluten-free" per FDA (< 20 ppm); "Sugar-free" per 21 CFR 101.60 | ### Step 4 — Typography & Formatting Compliance | Element | Requirement | |---|---| | Product Identity type size | Based on PDP area: < 5 sq in = 1/16"; 5-25 sq in = 1/8"; 25-100 sq in = 3/16"; > 100 sq in = 1/4" | | Net quantity type size | Based on PDP area per 21 CFR 101.7(j) | | Ingredient statement | Minimum 1/16" (0.0625") type height; specific font legibility rules | | Allergen declaration | "Contains:" statement or parenthetical within ingredient list; no smaller than ingredient list type | | Nutrition Facts | Prescribed format, fonts (Franklin Gothic Heavy/Helvetica Black), hairlines | ### Step 5 — Barcode & Identification Validation - UPC-A or EAN-13 check digit validation. - Adequate quiet zone around barcode (minimum 9 modules left, 9 modules right for UPC-A). - Barcode dimensions within GS1 specification (80-200% magnification). - Lot code and date marking format consistency. ### Step 6 — Digital Shelf Readability Check When packaging appears as a product image on e-commerce: - **Hero Image**: Is the brand name legible at thumbnail size (150×150 px)? - **Claims Visibility**: Are key claims readable on mobile (< 400px width)? - **Nutrition Panel**: Is the nutrition facts legible in zoom view? - **Color Contrast**: WCAG AA compliance for text on packaging backgrounds. ## Output Specification ```yaml output: overall_compliance: string # "compliant" | "non_compliant" | "needs_review" compliance_score: float # 0-100 findings: list[Finding] panel_status: pdp: string # "pass" | "fail" | "warning" info_panel: string back_panel: string critical_issues: int # Print-blocking issues warnings: int # Should-fix before print recommendations: int # Best practice suggestions missing_elements: list[string] # Required elements not found claims_validation: list[ClaimResult] print_ready: boolean # Final go/no-go recommendation ``` ## Analysis Framework **Packaging Compliance Severity Model**: | Severity | Impact | Examples | Action | |---|---|---|---| | **Critical (P0)** | Product recall risk, import detention, regulatory action | Missing allergen declaration, wrong net quantity, unauthorized health claim | Stop print. Fix immediately. | | **Major (P1)** | Retailer rejection, consumer complaint risk | Ingredient order error, wrong nutrition facts format, missing Prop 65 | Fix before print. | | **Minor (P2)** | Audit finding, best practice gap | Type size slightly under threshold, missing recycling symbol | Fix in next print run. | | **Advisory** | Opportunity to improve effectiveness | Better claim hierarchy on PDP, enhanced readability | Consider for next revision. | ## Examples **Input**: Front panel of a granola bar packaging. - Copy: "SuperGrain Protein Bar — ALL NATURAL — 20g Protein — Gluten Free — Net Wt. 2.4 oz" **Findings**: 1. **Critical**: "ALL NATURAL" — FDA has proposed (not finalized) definition; currently high enforcement risk. Recommend removal or replacement with specific claims. 2. **Major**: "20g Protein" — Qualifies as "Excellent Source of Protein" (≥ 10g per RACC), but the nutrient content claim format should reference the DV% basis under 21 CFR 101.54. 3. **Pass**: "Gluten Free" — Acceptable if product tests < 20 ppm gluten per FDA rule. 4. **Pass**: Net weight statement present. Verify type size ≥ 1/8" for this PDP area. 5. **Advisory**: Consider adding "Non-GMO" if verified — high consumer demand in this category. ## Guidelines - Packaging validation must occur at proof stage, not after print. Changes post-print cost 10-50x more. - Always validate against the most restrictive market if selling across multiple jurisdictions. - Certification logo usage must comply with each certifier's brand guide (size minimums, color specs, placement rules). - Keep a version-controlled record of every packaging proof reviewed and findings resolved. - Coordinate with procurement on lead times — some critical fixes may require plate changes. - When in doubt about a claim, escalate to regulatory counsel — do not self-approve. ## Validation Checklist - [ ] All required labeling elements are present on the correct panels. - [ ] Ingredient statement is in descending order of predominance with correct sub-ingredient formatting. - [ ] Allergen declarations cover all Big 9 allergens present in the product. - [ ] Nutrition Facts panel follows current FDA format requirements. - [ ] Net quantity statement meets type size and placement requirements. - [ ] All on-pack claims are cross-referenced against the approved claims library. - [ ] Certification logos meet each certifier's usage guidelines. - [ ] Barcode check digit validates correctly and meets GS1 size/quiet zone specs. - [ ] State-specific requirements (Prop 65, deposit markings) are included for applicable markets. - [ ] Digital shelf readability is confirmed at thumbnail and mobile sizes.
