Kosher certification allows companies to have an periphery over their competitors and allows them to sell to more clients than formerly and creates export opportunities that previously did not exist to them. Kosher Certification is also taken out by many clients even if they are not selling into the Kosher marketplace or to Jewish people as it is seen as a sign of quality and support.
Kosher certification is very different to ISO, HACCP, BRC, & ORGANIC certifications as it is based on our religion rather than on health and safety aspects. We always must use one of our Rabbis for the Initial Inspections, Audits or supervision as a requirement to comply with Kosher regulation and Kosher law.
However I must point out that there is a vast difference between Kosher Agencies and the validity and acceptance of Kosher Certificates. Kosher certification is very different from other certifications in that it all depends on who is giving the certification. If it is a small agency or a local Rabbi or a non recognized agency then the Kosher certificate will not be recognized and the company will find that their certificates are being rejected.
