site:developers.google.com/search/docs/appearance/structured data/merchant listing "Offer level merchant return policies" "hasMerchantReturnPolicy" "override"

Google’s merchant-listing documentation confirms that Offer.hasMerchantReturnPolicy defines a product-specific return policy. When both offer-level and organization-level policies exist, the more specific offer-level policy overrides the organization-level policy.

• Site-wide policy: Put hasMerchantReturnPolicy under Organization.
• Product exception: Put hasMerchantReturnPolicy under the product’s Offer.
• Precedence: Google uses the offer-level policy for that product instead of the organization-level policy.
• Scope: Offer-level markup supports only a subset of the properties available for organization-level return policies.
