Most label errors don\'t come from miscalculated nutrients — they come from a wrong serving size that cascades through every value on the panel. The FDA standardizes serving sizes through the Reference Amount Customarily Consumed (RACC) table, and applying the correct RACC is the single most impactful step in label compliance. This guide walks through how the RACC system works, how the 2020 update changed it, and how to apply it to your product.
The RACC System
Under 21 CFR 101.12, every packaged food belongs to one of ~150 product categories. Each category has an FDA-assigned RACC — the standard amount the average person consumes in one sitting, based on NHANES (National Health and Nutrition Examination Survey) data. Your serving size on the label must match the RACC for your category.
Common RACCs (post-2020 update):
| Category | Pre-2020 RACC | Current RACC (2020+) |
|---|---|---|
| Ice cream | 1/2 cup | 2/3 cup |
| Soda / soft drinks | 8 fl oz | 12 fl oz |
| Bagels | 55 g | 110 g |
| Yogurt | 227 g (8 oz) | 170 g (6 oz) |
| Bread, sliced | 50 g (1 slice) | 50 g (1 slice) |
| Cookies | 30 g | 30 g |
| Salad dressing | 30 g | 30 g |
| Granola bars | 42 g | 40 g |
| Coffee, brewed | N/A | 12 fl oz |
How to Apply the RACC to Your Product
Three steps:
- Step 1: Find your product category in the RACC table. The categories are detailed — "snack chips" is different from "popcorn," "fruit juice 100%" is different from "fruit drinks." Use the most specific match.
- Step 2: Convert the RACC into a household measure for your specific product. The RACC table specifies amounts in grams or fl oz. You translate that into "1 cup," "3 cookies," "2 tablespoons" — whichever makes sense for your product. The household measure goes on the label first, with the gram/mL equivalent in parentheses.
- Step 3: Calculate servings per container. Divide your total package weight by the RACC-equivalent serving size. Round down to a whole number unless your package contains an even multiple.
Single-Serve Containers Up to 200% of RACC
Special rule: if a single-serve container holds up to 200% of the RACC, the entire package can be declared as "1 serving per container" — even if mathematically it contains "1.6 servings." This applies to many single-serve specialty products and was clarified in the 2020 modernization.
Example: A 16-oz bottle of premium iced tea (RACC 8 fl oz). The bottle contains 2x the RACC. Can be labeled as "1 serving per container" with 16 fl oz noted. The label shows nutrition values for the whole 16 oz.
The Dual-Column Trigger
Packages containing 2-3 servings of products consumers reasonably eat in one sitting trigger the dual-column rule under 21 CFR 101.9(b)(12). The label must show both "per serving" and "per container" values side-by-side. Examples:
- 20-fl-oz beverage (1.67 servings at 12 fl oz RACC) — dual-column required.
- 1-pint ice cream (3 servings at 2/3 cup RACC) — dual-column required.
- Family-size 2-liter soda (~5.6 servings) — NOT dual-column; standard format.
- 3-serving bag of chips (1 oz each) — dual-column required.
Our dual-column generator handles the format automatically when you identify your product as a single-sitting multi-serving package.
Household Measure Formatting
The FDA standardizes how serving size is written:
- Household measure first, then metric in parentheses. "1 cup (228g)" — not "228g (1 cup)."
- Use fractions for partial amounts. "2/3 cup" not "0.67 cup."
- Use plain English measurements. "3 cookies," "2 tablespoons," "1 slice" — not technical units like "milliliters" except for liquids.
- Be specific for variable items. "About 3 cookies (34g)" if cookies vary slightly in size.
Pitfalls to Avoid
