A Group 1 ingredient does not require a kosher certificate or kosher symbol.

A Group 2 ingredient requires a kosher certificate, but no kosher symbol printed on the package.

A Group 3 ingredient requires a kosher certificate and a kosher symbol printed on the package.

A Group 4 ingredient is bulk packaged and only approved from a specific source.

A Group 5 ingredient is bulk packaged and only approved from a specific source when accompanied by a special letter.

Group 6 and 7 ingredients are not approved for use in kosher products, and Group 7 ingredients are not allowed in a kosher certified facility.
