Who has to follow FDA food labeling rules?

Anyone who packages, imports, or sells FDA-regulated food in the U.S. — domestic or foreign. Foreign companies must meet the same labeling standards as U.S. companies. Meat, poultry, and egg products fall under USDA and follow a different framework.

Does FDA approve or pre-approve food labels?

No. FDA doesn't review or approve food labels before sale. The company is responsible for making the label compliant, and FDA checks labels during import review and inspections. A non-compliant label can lead to detention or refusal, so the work has to be done up front.

What's the difference between this and the requirements page?

This page explains what the Food Labeling Guide is and how a label is organized. For the full, element-by-element requirements, see our FDA food labeling requirements guide; for the regulatory framework and recent changes, see our food label regulations page. Think of this as the orientation, and those as the detail.

Are Nutrition Facts panels always required?

Most packaged foods need a Nutrition Facts panel, though there are limited exemptions (for example, some very small businesses or certain foods). When required, the panel must follow the current format under 21 CFR 101.9.

What are the most common labeling mistakes?

Missing or incorrectly declared allergens, ingredient lists not in descending order by weight, an outdated or misformatted Nutrition Facts panel, claims that aren't supported, and type that's too small or poorly placed. These are frequent causes of import holds.

Do supplements and beverages use the same label?

Not exactly. Dietary supplements use a Supplement Facts panel rather than Nutrition Facts and have their own rules. Most beverages follow the general food label, while alcohol labeling is largely handled by TTB. The Guide is aimed primarily at conventional packaged food.

FDA Guidance — Food Labels

Last updated: July 2026

What Is the FDA Food Labeling Guide?

Q: What is the FDA Food Labeling Guide?

It's FDA's Guidance for Industry on food labeling — a plain-language, question-and-answer document that explains how to label packaged food. It's a help resource that reflects FDA's current thinking; the binding requirements themselves sit in the regulations at 21 CFR Part 101 and in the Federal Food, Drug, and Cosmetic Act.

Q: Is the Guide the same as the law?

No. Guidance documents explain how FDA interprets and applies the rules, but they aren't themselves legally binding. The enforceable requirements are the regulations in 21 CFR Part 101 and the misbranding provisions of the FD&C Act. The Guide helps you meet those rules; it doesn't replace them.

Q: What are the two label panels?

The principal display panel (PDP) is the part shoppers see first — it carries the statement of identity and the net quantity. The information panel, usually to the right of the PDP, carries the ingredient list, allergen declaration, Nutrition Facts, and the name and address of the manufacturer, packer, or distributor. Knowing which panel holds what is the first step to a correct layout.

Q: What has to appear on a food label?

At a minimum: a statement of identity, net quantity, an ingredient list, allergen information, a Nutrition Facts panel, and the responsible firm's name and address — plus any claims done correctly. Each of these has its own detailed rule in 21 CFR Part 101, which our food labeling requirements guide covers in depth.

Q: How are allergens handled?

Major food allergens must be declared clearly, either within the ingredient list or in a separate 'Contains' statement. There are nine major allergens after sesame was added. Our allergen labeling page covers exactly how to declare them.

The "FDA Food Labeling Guide" is FDA's Guidance for Industry on food labeling — a plain-language, question-and-answer document that walks through how to label packaged food. It's a help resource, not the law itself: the binding requirements live in the regulations at 21 CFR Part 101 and in the Food, Drug, and Cosmetic Act. This page explains what the Guide is, how a food label is organized, and where to find each rule. One thing it doesn't do — FDA doesn't pre-approve food labels. For the full requirements, see our food labeling requirements guide.

Think of the Guide as the map, and Part 101 as the territory. Knowing the difference is the fastest way to a label that clears.

Key Takeaways

The Guide is guidance — FDA's plain-language help document, in Q&A form.
The law is the regulation — the binding rules are in 21 CFR Part 101 and the FD&C Act.
Two panels — the principal display panel and the information panel each carry specific elements.
Six core elements — identity, net quantity, ingredients, allergens, Nutrition Facts, name/address.
No pre-approval — FDA checks labels at import and inspection, not before sale.
This page orients; the deep pages explain — each requirement links out to its own guide.

Guidance vs. regulation — why it matters. FDA guidance documents describe the agency's current thinking and help you comply, but they don't create binding legal obligations on their own. When a question turns on a hard requirement — type size, an allergen declaration, a claim — the answer comes from 21 CFR Part 101, not the Guide's summary. The Guide points you to the rule; it isn't a substitute for it.

Label Anatomy

The Two Panels

Almost every question about "where does this go?" comes down to two areas of the package:

Principal Display Panel (PDP)

The part shoppers see first on the shelf. It carries the statement of identity (what the product is) and the net quantity of contents.

Information Panel

Usually immediately to the right of the PDP. It carries the ingredient list, allergen declaration, Nutrition Facts, and the name and address of the manufacturer, packer, or distributor.

Getting the split right is the first thing a reviewer checks — required information in the wrong place is still a labeling problem, even if every word is correct.

The Core Elements

What the Guide Walks Through

Element	In short	Go deeper
Statement of identity	The common name of the food, on the PDP	21 CFR 101.3
Net quantity	Amount of product, on the PDP	21 CFR 101.7
Ingredient list	All ingredients, descending by weight	Ingredient list rules
Allergens	Major allergens declared clearly	Allergen labeling
Nutrition Facts	Current panel format	21 CFR 101.9
Claims	Nutrient content & health claims, done correctly	Regulations & recent changes

Scope

What the Guide Doesn't Cover

USDA foods

Meat, poultry, and egg products are labeled under USDA rules, not this framework.

Supplements

Dietary supplements use a Supplement Facts panel and their own rules — see our supplement requirements.

Alcohol

Most alcohol labeling is handled by TTB, a separate agency, rather than the food label rules.

⚠ Exporting to the U.S.? Foreign products must meet the same U.S. label rules as domestic ones — a label that's compliant at home isn't automatically compliant here. See exporting food to the U.S.: labeling.

Step by Step

Using the Guide in Practice

Confirm it's FDA-regulated

Check the product falls under FDA, not USDA — the frameworks differ.

Lay out the two panels

Decide what belongs on the PDP versus the information panel.

Build each element

Work through identity, net quantity, ingredients, allergens, and Nutrition Facts against Part 101.

Check claims

Make sure any claim meets its rule and nothing is false or misleading.

Verify format & legibility

Confirm type size, placement, and prominence meet the rules.

Review before printing

Have the finished label checked before a print run or shipment.

Catch It Before the Border

Have Your Label Reviewed Before You Print

FDA Registration Assistance reviews food labels against 21 CFR Part 101 — identity, net quantity, ingredients, allergens, Nutrition Facts, and claims — so problems surface before a print run or a held shipment, not after.

3. Who has to follow FDA labeling rules?

Anyone packaging, importing, or selling FDA-regulated food in the U.S., domestic or foreign. Foreign companies meet the same standards. Meat, poultry, and egg products fall under USDA's different framework.

4. What are the two label panels?

The principal display panel (PDP) is seen first — it carries the statement of identity and net quantity. The information panel carries ingredients, allergens, Nutrition Facts, and the firm's name and address.

5. What has to appear on a food label?

At minimum: statement of identity, net quantity, ingredient list, allergen information, Nutrition Facts, and the responsible firm's name and address — plus any claims done right. Each has its own rule in Part 101; see our requirements guide.

6. Does FDA approve food labels?

No — there's no pre-approval. The company is responsible for compliance, and FDA checks labels at import review and inspection. A non-compliant label can be detained or refused, so the work happens up front.

7. How is this different from the requirements page?

This page explains what the Guide is and how a label is organized. For element-by-element detail, see the requirements guide; for framework and recent changes, the regulations page.

8. How are allergens handled?

Major allergens must be declared clearly, in the ingredient list or a separate "Contains" statement. There are nine after sesame was added. Our allergen page covers how.

9. Are Nutrition Facts always required?

Most packaged foods need one, with limited exemptions (e.g., some very small businesses). When required, it must follow the current format under 21 CFR 101.9.

10. What are the most common mistakes?

Missing or misdeclared allergens, ingredients not in descending order by weight, an outdated Nutrition Facts panel, unsupported claims, and type too small or poorly placed — all frequent causes of import holds.

11. Can labeling problems delay a shipment?

Yes — labeling issues are among the top reasons food is detained or refused at entry. Because there's no pre-approval, an uncaught error surfaces at the border, at the worst time.

12. Do supplements and alcohol use this guide?

Not really — supplements use a Supplement Facts panel and their own rules, and alcohol labeling is largely TTB's domain. The Guide is aimed at conventional packaged food.

13. Can I create my own label?

Yes — many companies also have it reviewed before printing, since formatting, allergens, and claims are easy to get wrong and costly to fix after a print run or a held shipment.

14. How does FDA Registration Assistance help?

It reviews labels against 21 CFR Part 101 — identity, net quantity, ingredients, allergens, Nutrition Facts, claims — and flags issues before printing or import, for companies across 135+ countries. Contact info@fdaregistrationassistance.com or +1 (928) 275-8333.
