FDA Registration for Single-Serve Food Packaging
The formats single-serve comes in, the two questions they share, and where each format's rules live.
Key Takeaways
- Two questions for every format — the material and the single-serving label.
- The material is a food contact substance — cup, film, tray, or bottle.
- Single-serving container rule — under 200% of the RACC, the whole pack is one serving.
- You can't shrink the serving — it's set by FDA's reference amount.
- Slightly oversized flips to dual column — 200–300% of the RACC needs both columns.
- Format sets the specifics — a sachet, pouch, and bottle differ in the details.
Two Questions Every Single-Serve Pack Shares
Whatever the format, single-serve compliance comes down to these two — get them right and the format details slot in around them:
Is the packaging cleared?
The cup, film, tray, or bottle is a food contact substance and must be cleared for its use and conditions. See food packaging and flexible packaging.
How is the serving handled?
The single-serving container rule: under 200% of the reference amount, the whole pack is one serving — and the serving can't be shrunk. See portion-controlled foods.
Single-Serve Formats — and Where Each One's Rules Live
Single-serve shows up in several package formats. Each shares the two questions above but has its own specifics:
| Format | Typical products | Where the rules are |
|---|---|---|
| Cup, tub, or tray | Yogurt, dips, snacks, ready meals | Single-serving label + material |
| Sachet / stick pack | Drink mixes, seasonings, condiments | Sachet guide |
| Pouch | Purees, snacks, single-serve liquids | Pouch guide |
| Bottle or can | Single-serve beverages and foods | Single-serving label + material |
| Clamshell / blister | Fresh-cut, grab-and-go items | Material + single-serving label |
| Condiment packet | Ketchup, dressing, sugar | Sachet / small-package format |
The Single-Serving Rule in One Place
The label side of single-serve is governed by where the pack falls against the reference amount — the short version:
- Under 200% of the RACC, sold individually — single-serving container: the whole pack is one serving
- You can't declare a smaller serving — it's fixed by FDA's reference amount, not chosen
- 200–300% of the RACC — a "single-serve" pack this large needs dual-column Nutrition Facts
- Very small packs — linear or tabular formats apply, but identity, ingredients, and allergens still must appear
Food or Supplement?
A single-serve format can hold either a conventional food or a dietary supplement, and they use different labels. A single-serve beverage or snack uses Nutrition Facts; a single-serve vitamin, mineral, or electrolyte stick or shot intended to supplement the diet is a dietary supplement and uses a Supplement Facts panel.

Frequently Asked Questions
1. Do single-serve food products need FDA registration?
The facility that manufactures, processes, packs, or holds the food registers with FDA, and foreign facilities need a U.S. Agent — the same as any packaged food. Single-serve doesn't change registration. What it drives are two questions common to every single-serve format: whether the packaging material is a cleared food contact substance, and how the single-serving label rule applies.
2. What do all single-serve packaging formats have in common?
Two things. First, the material — whether a cup, film, pouch, or bottle — is regulated as a food contact substance and has to be cleared for its use. Second, the label follows the single-serving container rule: a pack sold individually with less than 200% of the reference amount is labeled with its entire contents as one serving. Whatever the format, those two questions apply.
3. What is the single-serving container rule?
Under 21 CFR 101.9(b)(6), a product packaged and sold individually that contains less than 200% of the applicable reference amount (RACC) is a single-serving container — so the whole package is labeled as one serving. And you can't declare an artificially small serving to improve the numbers; the serving is based on FDA's reference amount, not the manufacturer's preference. There's a dedicated portion-controlled guide for the full detail.
4. Which single-serve format do I have?
Common formats include rigid cups, tubs, and trays; flexible sachets and stick packs; single-serve pouches; bottles and cans; and clamshells or blisters. Each shares the material and single-serving-label questions but has its own specifics — a sachet is too small to hold a full label, a pouch may involve multi-layer film, a bottle raises beverage rules. Identify your format and the specific requirements follow.
5. How is the single-serve packaging material regulated?
As a food contact substance — the same framework whatever the format. The cup resin, pouch film, tray, or bottle must be cleared for its use (through an existing regulation, GRAS, a Threshold of Regulation exemption, or a Food Contact Notification), matched to the conditions of use. A company that only makes the packaging material generally isn't a food facility; its obligation is that the material is cleared.
6. Can I make the serving look smaller on a single-serve pack?
No. For a single-serving container, the whole package is the serving, and the serving size is set by FDA's reference amount for the product — not chosen to make the calories or sugar look lower. A "100-calorie" single-serve pack has to genuinely be 100 calories for the whole pack. Single-serve is an honest-portion feature, not a way to shrink the declared numbers.
7. What if my single-serve pack is a bit large?
If it contains between 200% and 300% of the reference amount — a size that could be eaten in one sitting or split — it generally needs dual-column Nutrition Facts, showing per serving and per container. So a slightly oversized "single-serve" pack can actually cross into required dual-column labeling. The exact size relative to the reference amount decides it.
8. How do very small single-serve packs get labeled?
Small packages get scaled label formats: under about 12 square inches of surface area, a linear Nutrition Facts format (or in limited cases an address or phone line) may be used; under about 40 square inches, a tabular format. Sachets and tiny condiment packets often rely on the outer box for the full label. But identity, ingredients, and allergens still have to appear somewhere the consumer can access.
9. Do single-serve packs for foodservice differ?
Yes. Single-serve items supplied to restaurants, cafeterias, and hotels follow the foodservice-supply rules: the supplier registers, food for immediate consumption may be exempt from a retail Nutrition Facts panel, and identity, ingredients, and allergen information still travel to the operator. Retail single-serve packs follow the single-serving labeling rules instead.
10. Is a single-serve stick or shot a food or a supplement?
It depends on the contents and marketing. A single-serve vitamin, mineral, or electrolyte stick or shot intended to supplement the diet is a dietary supplement, using a Supplement Facts panel; a single-serve beverage or snack is a conventional food using Nutrition Facts. The same single-serve format can be either, so classify the product before designing the label.
11. Do imported single-serve products follow the same rules?
Yes. Imported single-serve packs must meet the same FDA material, serving-size, and labeling rules, use U.S. reference amounts, and the importer holds FSVP. A single-serve pack sized to another market's serving conventions may need its serving size and Nutrition Facts recalculated to the U.S. reference amount, and its material confirmed as a cleared food contact substance.
12. Does registration mean FDA approved my single-serve packaging?
No. FDA doesn't pre-approve food, packaging, or facilities — registration just puts the facility on record. It doesn't certify your material, serving size, or label; those remain your responsibility. Your single-serve product still has to meet the food-contact, serving-size, and labeling requirements for its format and food.
13. What are the common mistakes with single-serve packaging?
Declaring a serving smaller than the reference amount; missing dual-column labeling on a slightly oversized pack; using packaging material not cleared for the conditions of use; under-labeling a small pack below what's still required; and treating a supplement stick as a food. Most trace back to not separating the two core questions — the material and the single-serving label — and then the format specifics.
