Kosher: Check the selected issuer and proprietary mark

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.

Check the selected issuer and proprietary mark

If a seller presents general accreditation as authority to license the OU symbol, require the actual OU certification and permission evidence. OU owns that mark and grants its use through its process; another body’s certificate is not OU permission. Different kosher issuers may have different arrangements and buyer acceptance. Kayra/QRS preparation does not acquire the issuer’s rabbinic decision.

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.
