Kosher Certification for Flavor and Ingredient Companies

Your kosher letter is what lets your manufacturer customers certify their products. Why ingredient suppliers certify — and how.

If you make flavors, colors, enzymes, or functional ingredients, your kosher certification isn’t just for you — it’s what unlocks your customers.

The chain — Manufacturers can only certify a finished product if every ingredient carries a kosher letter. Yours is a gatekeeper for their certification.

What we verify — Every sub-component, solvent, carrier, and processing aid, traced to source, and we issue the letter of certification your B2B customers need.
