🇺🇸 Ingredient List Order: Descending Order by Weight in US

Yes — in the United States, ingredients must be listed in descending order by weight as recorded at the time of their use in manufacture, with limited exceptions.

What the Rule Is

The ingredients list is one of the most important parts of a food label. In the United States, ingredients must be listed in descending order of weight. FDA regulation 21 CFR 101.4(a)(1) requires ingredients to be "listed in descending order of predominance by weight". Ingredients present at 2% or less of the food may be grouped at the end of the list following a statement such as "contains 2% or less of ...".
