From the US Copyright Office[1]: "A mere listing of ingredients is not protected under copyright law", and from their linked circular on that page [2]: "forms typically contain empty fields or lined spaces as well as words or short phrases that identify the content that should be recorded in each field or space".
A list of identifiers and their weights seems pretty explicitly not protected under one or the other of these.
