In Canada and the U.S., tomato sauce (marinara) is typically sold jarred or canned, with minimal ingredients, and is not normally used as is. Related ingredients are tomato purée and tomato paste, each of which is similar but paste has a thicker consistency. Tomato purée and tomato paste have US FDA standards of identity (since 1939) for percentage of tomato solids, and historically did not contain seasonings other than salt; in recent decades variants with basil or other traditional Italian seasonings became common. Tomato sauce is non-standardized.
