Kosher: Match the certificate to the exact product
Kosher status depends on the chosen issuer's accepted products, materials and manufacturing conditions. OU is a named example, not the universal authority for every programme.
Match the certificate to the exact product
For a product carrying an OU symbol, check the specific brand/product and designation using current issuer information, and review any alerts. A similar product name or an old letter for another manufacturer is insufficient. Dairy-equipment conditions and Passover designation must not be guessed from the ingredient front label. Investigate the mismatch before presenting the product as within current scope.
Programme conditions and worked assessment
Example: A business expects automatic pareve status for a vegan product and sends only the ingredient list. Explain equipment history and production arrangement as well as ingredients. The actual issuer assesses the designation; vegan status is not that decision. Compare accepted ingredients with product lists and proposed labels. Do not assume another issuer's raw-material certificate is automatically accepted. Printing a symbol requires real permission; a consultant's review is not a mark licence. Clarify exactly which finished products the issuer has assessed.
Evidence and authority boundary
OU's published process is an example source, not evidence of Kayra/QRS recognition. Required equipment treatment and religious determinations belong to the actual authorised issuer.
