Practical answers about kosher certification
Understand the application, review and maintenance basics before discussing the details of your products and facility.
What is kosher certification?
Kosher certification is an independent review of ingredients, products, equipment and production controls against defined kosher requirements. For approved products, certification documents the authorized scope and may permit use of the certifier’s mark under agreed conditions.
Does my company need kosher certification?
Kosher certification is usually a commercial choice rather than a general legal requirement. A buyer, distributor, retailer or target market may request it. Companies also pursue certification to make products accessible to kosher-observant customers and to support commercial discussions.
Can companies outside the United States apply?
Yes. KAG is positioned to work with manufacturers, suppliers and exporters internationally. The practical review plan depends on facility location, production complexity and the proposed certification scope.
Can KAG certify an exporting company?
An exporter may apply when it manufactures products or controls the relevant product and supply-chain information. Where production is outsourced, the manufacturing site and responsible parties must be included in the review.
How long does certification take?
Timing depends on the number of products and sites, formulation complexity, document readiness, facility scheduling and whether changes are required. KAG can give a more useful indication after reviewing an application; no responsible certifier can promise one timeline for every facility.
What information is required?
Applicants typically provide product lists, formulas or ingredient lists, supplier details, relevant ingredient certificates, production flow information, facility locations and an overview of shared equipment. KAG will identify what is needed for the specific scope.
Do all ingredients need to be reviewed?
Ingredients and processing aids relevant to certified production must be disclosed and reviewed. Materials used on shared equipment can also affect the assessment, even when they do not appear in the final product.
Can a facility make kosher and non-kosher products?
In some situations, yes. Feasibility depends on the ingredients, equipment, temperatures, scheduling, segregation and cleaning or changeover controls. The arrangement must be evaluated for the actual facility.
What happens when an ingredient changes?
Proposed ingredient or supplier changes should be submitted to KAG before use in certified production. Prior review protects the approved product status and avoids preventable interruptions.
Does certification need to be renewed?
Kosher certification is an ongoing program rather than a one-time test. Certification normally includes periodic review and renewal, subject to the agreement and continued compliance.
Can private-label products be certified?
Yes, where the brand owner, manufacturer and product scope can be documented appropriately. The manufacturing facility and applicable formulas, ingredients and labels remain part of the review.
Can multiple factories be included?
Potentially. Each production location must be disclosed and assessed because ingredients, equipment and controls can differ by site. The certification documents must identify the approved scope accurately.
Does kosher certification help with exports?
It can support access to buyers or channels that request recognized kosher documentation. It may also make products easier to evaluate for kosher-conscious customers. Certification does not replace import, food-safety, labeling or customer-specific requirements and does not guarantee a sale.
What happens after I apply?
KAG reviews the initial information, clarifies the proposed scope and requests any missing product or facility details. The next steps can then be planned, including document review and a facility assessment where required.
Can an existing certification be reviewed or transferred?
Yes. Provide the current certification scope, product list, facility details and relevant documentation. KAG will review the program independently and explain any requirements before a transition can be approved.
