Certification
This tier reads the ingredient list against Scripture's clean and unclean lists. It does not require rabbinic certification and does not separate meat and dairy.
Tier definition
A reliable hechsher is the preferred way to establish that a processed food is kosher. Where none is present, the ingredient list is read against CJLS rulings and the result is marked for your judgement.
Rabbinical Assembly, "A Guide to Jewish Religious Practice" (Klein, 1979), ch. 21
A recognized hechsher settles the question. Without one, the ingredient list is read for unclean species and questionable animal derivatives.
MJRC Standards of Observance, Kashrut section
Processed foods are relied upon only with a recognized hechsher, because ingredients, equipment and processing aids cannot be verified from the label alone. Hey Kosher reports what is printed on the package; the agency has the final word.

Gelatin
Gelatin from a pig is from an unclean animal. Gelatin whose source is not stated is usually porcine or bovine, so we ask you to check the source rather than guess.
Leviticus 11:7-8 applied to derivatives
Gelatin is so thoroughly transformed from its source that it is no longer considered the forbidden substance. The CJLS accepts gelatin from any source as kosher and pareve.
