Error 100037 — Listing constraint violation

Your listing violates a category-specific constraint — typically around bundling rules, multipack disclosures, condition statements, or category-specific required disclosures.

Many Amazon categories have unique constraints not enforced via standard schema validation: e.g., apparel needs size charts, supplements need facts panels, electronics need power specifications.

1. Read the specific constraint in your processing report — Amazon usually cites the category rule.
2. Update the listing to satisfy the constraint (add required attributes, fix multipack designation, add condition note).
3. For apparel: confirm size chart matches Amazon's standardized size guide.
4. For supplements: include the supplement_facts attribute with correctly formatted ingredients.

• Selling supplements without a supplement_facts panel — automatic constraint violation
• Marking a 6-pack as a single unit — multipack disclosure missing
