Ingredient List Order: FDA Rules

The ingredient list looks like the simplest part of a label, but it has precise rules — and it's the part your customers actually read.

Heaviest first, always

Ingredients must be listed in descending order of predominance by weight (21 CFR 101.4(a)(1)). Weight means the weight going into the recipe, and the order is not negotiable: if sugar outweighs strawberries in your jam, sugar comes first, however that looks marketing-wise.

The 2%-or-less shortcut

Minor ingredients don't need exact ordering. Anything at 2% or less by weight may be grouped at the end after wording like "Contains 2% or less of: salt, baking soda, vanilla extract" (101.4(a)(2)). You can also use 1.5%, 1%, or 0.5% as the stated threshold — but no ingredient in the group may exceed it.

Compound ingredients: two legal options

If you use a made ingredient (say, soy sauce), 101.4(b)(2) gives two options:

1. Parenthetical — name it and list its components: "soy sauce (water, soybeans, wheat, salt)".
2. Dispersed — skip the compound name and fold each component into your overall descending order.

The parenthetical is usually clearer and keeps allergen sources visible.

Names: common and specific

Ingredients go by their common or usual name, and specific rather than collective: "sugar" legally means sucrose (101.4(b)(20)); oils must name the source with hydrogenation status ("partially hydrogenated soybean oil"). A handful of collective names are explicitly permitted — "spices", "natural flavors", leavening in parentheses.

This is also why raw USDA database names don't belong on a label. "Wheat flour, white, all-purpose, enriched, bleached" is a database record; your jar should say "wheat flour" (with enrichment ingredients where applicable). A good workflow keeps the database record for the math and lets you set a clean display name for the list — that's exactly how our builder splits it.

Quick checklist

• Weigh every ingredient in the recipe; order by those weights.
• Group ≤2% ingredients at the end if that helps readability.
• Expand compound ingredients (or disperse them).
• Simplify names for the label — but never in a way that hides an allergen.
