Kosher Certification for Contract Manufacturers

Separate customer confidentiality from certification visibility

The certifier needs enough formula and supplier information to assess each product, but brand owners may restrict how data is shared. Establish direct confidential disclosure routes where needed. The co-packer should still maintain an internal link between each run, formula version and approval.

Control the full production calendar

A line approved for one product may also run customer formulas outside the certified scope. New projects and trials should enter a review workflow before scheduling. Weekend or short-notice runs need the same controls as routine production.

• Customer and product approval status
• Ingredient receipt and segregation
• Shared-line sequence and changeover
• Artwork and certification-mark authorization

Define brand-owner responsibilities

The commercial agreement should identify who submits formula changes, who approves labels and who receives renewal documents. If the customer buys ingredients directly, responsibilities for approved sourcing must be explicit.

Make the program scalable

Use product codes and system flags instead of relying on staff memory. Maintain templates for new-customer information and pre-production checks. A structured onboarding process helps the facility add business without weakening existing certification controls.
