FDA Form 3480 is required when a manufacturer or supplier wants to market a new food contact substance (FCS) or use an existing substance for a new application in food packaging or food processing equipment. Under Section 409(h) of the Federal Food, Drug, and Cosmetic Act, companies must submit this form as part of a Food Contact Notification (FCN) to the FDA at least 120 days before introducing the substance into interstate commerce.
The 21 CFR 170.101 regulations mandate that failure to submit an FCN for an unauthorized food contact substance can result in the product being deemed adulterated under federal law. According to the FDA’s Office of Food Additive Safety, over 2,400 effective FCNs are currently listed in the agency’s inventory, and the volume of submissions continues to grow each year.

What Is FDA Form 3480?
FDA Form 3480 is the standardized government form that serves as the framework for submitting a Food Contact Notification to the FDA. According to the FDA’s guidance documents, this form organizes all the technical and safety information the agency needs to determine whether a food contact substance is safe for its intended use.
The form is divided into six main parts. Part I covers general administrative information about the notifier and the submission itself. Part II addresses chemistry information, including the identity of the substance, its manufacturing process, impurities, intended use, stability data, migration testing results, and estimated daily intake calculations.
Part III focuses on safety information, including a safety narrative and toxicological profiles. Part IV covers environmental requirements under the National Environmental Policy Act (NEPA). Part V contains the certification section where an authorized official signs the submission. Part VI provides a list of all attached documents.
Completion of Form 3480 alone does not constitute a complete notification. The FDA requires that you also submit all supporting data, test results, and documentation that forms the basis of your safety determination.
Who Must File FDA Form 3480?
Form 3480 must be filed by any manufacturer or supplier of a food contact substance who intends to market that substance for use in food packaging, food processing equipment, or other food contact applications. This includes companies producing plastic polymers for food containers, coating manufacturers creating can linings, adhesive producers making labels for food packages, and additive suppliers providing antioxidants or stabilizers for packaging materials.
The filing requirement applies to both domestic and international companies. Foreign manufacturers must designate a U.S. agent for FDA communications. The FCN is proprietary to the specific manufacturer identified in the notification, meaning competitors cannot rely on another company’s FCN even if the substance is chemically identical.
| Party Type | FCN Required? | Notes |
|---|---|---|
| Manufacturer of new FCS | Yes | Primary filer for new substances |
| Supplier purchasing from FCN holder | No | Can rely on manufacturer’s FCN |
| Manufacturer using substance for new use | Yes | New application requires new FCN |
| Downstream packaging company | Depends | Must verify supplier has effective FCN |
| Importer of FCS | Yes, if no existing FCN | Must ensure regulatory compliance |
When Is FDA Form 3480 Required?
Situation 1: Marketing a New Food Contact Substance
Form 3480 is required whenever you want to introduce a substance into the market that has never been authorized for food contact use. According to 21 CFR 170.101, the notification must be submitted at least 120 days before the substance enters interstate commerce.
A substance qualifies as “new” if it is not already listed in the FDA’s existing food additive regulations in 21 CFR Parts 174-178, is not generally recognized as safe (GRAS), does not have an existing effective FCN from which you can purchase, and does not qualify for a Threshold of Regulation (TOR) exemption.
For example, if a polymer manufacturer develops a novel bio-based plastic from seaweed derivatives for use in food containers, they must file Form 3480 because this substance has no existing regulatory authorization.
| Scenario | Consequence |
|---|---|
| New polymer not listed in 21 CFR Part 177 | FCN required before marketing |
| Novel coating chemistry for beverage cans | FCN required; migration testing mandatory |
| New antimicrobial additive for packaging | FCN required; may need biocide-specific data |
| Innovative cellulose-based material | FCN required if not covered by existing regulations |
Situation 2: Using an Existing Substance for a New Application
Even if a substance already has regulatory clearance, Form 3480 is required when you intend to use it under different conditions than previously authorized. The FDA’s Office of Food Additive Safety considers a “new use” to include higher temperatures than previously tested, longer food contact times, different food types (such as switching from dry foods to fatty or acidic foods), higher concentrations in the finished material, or different article types (such as moving from rigid containers to flexible pouches).
Consider a manufacturer who has an effective FCN for a stabilizer used in polyethylene films contacting dry foods at room temperature. If that same manufacturer wants to use the stabilizer in polypropylene containers for hot-fill applications with fatty foods, they need to submit a new Form 3480 because the conditions of use have changed significantly.
Situation 3: New Manufacturer or Supplier
The FCN system is manufacturer-specific. Under Section 409(h)(2)(C) of the FD&C Act, an FCN is effective only for the manufacturer or supplier identified in the notification. If Company A holds an effective FCN for Substance X, Company B cannot simply manufacture and sell Substance X without filing their own FCN.
This requirement exists because the FDA’s safety determination is based on the specific manufacturing process, impurity profile, and specifications demonstrated in the original notification. A different manufacturer might produce the same substance with different impurities or purity levels.
| Scenario | Consequence |
|---|---|
| Purchasing FCS from FCN holder | No new FCN needed; can rely on supplier’s authorization |
| Manufacturing same FCS independently | New FCN required; cannot rely on competitor’s FCN |
| Purchasing from non-FCN holder | FCS may be unapproved; legal risk to both parties |
| Switching suppliers mid-production | Must verify new supplier has effective FCN |
When Is FDA Form 3480 NOT Required?
Understanding when Form 3480 is not required is equally important for avoiding unnecessary regulatory burdens.
Already Listed in FDA Regulations
If your substance is specifically listed in 21 CFR Parts 174-178 and you are using it within the conditions specified in the regulation, no FCN is needed. These regulations function as generic clearances that anyone can rely on. For instance, Section 177.1520 lists cleared polyolefin polymers, and manufacturers meeting those specifications can use the materials without an FCN.
GRAS Substances
Substances that are generally recognized as safe (GRAS) for food contact use do not require an FCN. The GRAS determination must be based on the same quantity and quality of scientific evidence required for a food additive approval. Companies can either self-determine GRAS status or submit a voluntary GRAS notice to FDA.
Threshold of Regulation (TOR) Exemptions
Under 21 CFR 170.39, if a non-carcinogenic substance migrates to food at levels below 0.5 parts per billion (ppb), the manufacturer can request a TOR exemption rather than filing an FCN. TOR exemptions are not proprietary, meaning anyone can rely on an approved TOR once it is granted.
Purchasing from an FCN Holder
If you are purchasing a food contact substance from the manufacturer or supplier named in an effective FCN and using it for the authorized purpose, you do not need to file your own Form 3480. However, you must be able to demonstrate that the notification is effective for your specific food contact substance by maintaining proper documentation.
The Form 3480 Submission Process: Step-by-Step
Step 1: Determine Regulatory Pathway
Before completing Form 3480, determine whether an FCN is the appropriate pathway. Review the FDA’s existing regulations to confirm your substance is not already authorized. Check the Inventory of Effective FCNs to see if your substance already has an effective notification from which you can purchase.
If your cumulative estimated daily intake (CEDI) exceeds 1 part per million (ppm), the FDA recommends filing a food additive petition instead of an FCN. For biocides, this threshold is 200 ppb.
Step 2: Gather Required Data
Form 3480 requires extensive supporting data. The chemistry information section demands chemical identity documentation (CAS name, CAS Registry Number, structural formula), manufacturing process details and flow diagrams, impurity profiles with typical and maximum levels, physical and chemical specifications, intended use conditions (temperature, food types, contact duration), stability data under intended conditions, migration testing results, and estimated daily intake calculations.
The toxicology section requires a safety narrative, comprehensive toxicology profiles, relevant toxicity studies, and literature search results. The amount of toxicological data needed depends on the exposure level.
| Exposure Level (CEDI) | Required Toxicity Data |
|---|---|
| Less than 0.5 ppb | No data required |
| 0.5 ppb to 50 ppb | Genotoxicity battery |
| 50 ppb to 1 ppm | Subchronic toxicity study (90-day) |
| Greater than 1 ppm | Food additive petition recommended |
Step 3: Conduct Migration Testing
Migration testing is critical for determining dietary exposure. According to the FDA’s Chemistry Recommendations guidance, testing protocols should simulate actual conditions of use.
For room-temperature applications, a test temperature of 40°C (104°F) for 10 days is recommended. For higher temperature applications, accelerated testing at 100°C for 2 hours may be appropriate. The FDA requires migration data for multiple time intervals and replicate samples.
Test samples should be made using the maximum intended use level of the FCS. Results must be expressed in both concentration (mg/L or mg/kg) and surface area basis (mg/in² or mg/dm²).
Step 4: Complete Part IV – Environmental Information
Every FCN must address NEPA requirements by including either a claim of categorical exclusion or an environmental assessment.
Categorical exclusions are available under 21 CFR 25.32 for substances used as components of food-contact surfaces of permanent or semi-permanent equipment, substances making up less than 5% by weight of the finished food contact material, substances used only in coatings, and substances that occur naturally in the environment.
If no categorical exclusion applies, you must prepare a full environmental assessment evaluating the potential environmental impact of your substance.
Step 5: Submit the Notification
Electronic submission through the FDA’s Electronic Submission Gateway (ESG) is strongly recommended. Alternatively, you can mail submissions on CD or DVD, or submit five paper copies to the Office of Food Additive Safety.
After submission, the FDA recommends sending an email to [email protected] to confirm receipt.
The 120-Day Review Timeline
Once FDA accepts your FCN, the statutory 120-day review period begins. The FDA will either allow the notification to become effective through inaction, issue a deficiency letter requesting additional information, or issue an objection letter if the safety standard is not met.
| Day Range | FDA Action | Notifier Response |
|---|---|---|
| Days 1-10 | Administrative review for completeness | Respond to any non-acceptance letters |
| Days 10-60 | Technical review by chemistry team | Be available for questions |
| Days 60-100 | Toxicology and environmental review | Respond promptly to deficiency letters |
| Days 100-120 | Final decision preparation | Prepare for marketing |
| Day 120 | FCN becomes effective if no objection | May begin marketing |
If FDA issues a deficiency letter, the 120-day clock may be extended while you provide additional information. Deficiency letters have increased in recent years, particularly for environmental assessments and inexperienced notifiers.
Real-World Examples and Scenarios
Example 1: The Plastic Additive Manufacturer
Scenario: ABC Chemical produces a new antioxidant stabilizer for use in polyethylene food packaging at up to 0.5% by weight. The finished packaging will contact fatty foods at temperatures up to 100°F.
| Action | Consequence |
|---|---|
| Identify substance as new (no existing authorization) | FCN required |
| Conduct migration testing in fatty food simulant | Generates exposure data |
| Calculate EDI at 25 ppb | Requires genotoxicity data |
| Submit Form 3480 with complete package | Starts 120-day review |
| FCN becomes effective | Can market to packaging manufacturers |
Example 2: The Coating Company Expanding Use
Scenario: XYZ Coatings has an effective FCN for a polymer coating used in beverage cans contacting aqueous foods at room temperature. They now want to sell the same coating for canned vegetables processed at 250°F.
| Action | Consequence |
|---|---|
| New temperature conditions not covered by original FCN | New FCN required |
| Conduct migration testing under retort conditions | May show higher migration |
| Higher exposure may require additional tox data | Could increase submission cost |
| Submit new Form 3480 | Starts new 120-day review |
Example 3: The Packaging Converter’s Dilemma
Scenario: DEF Packaging purchases a specialty plastic from a foreign supplier for use in food containers. The supplier claims the material is “FDA compliant” but cannot provide an FCN number.
| Action | Consequence |
|---|---|
| Supplier has no effective FCN | FCS may be unapproved |
| Material not listed in 21 CFR | Cannot rely on food additive regulation |
| DEF uses material in food containers | Products may be adulterated |
| FDA inspection reveals unapproved FCS | Warning letter, seizure, or injunction possible |
Mistakes to Avoid
Mistake 1: Assuming Similarity Equals Authorization
Many companies believe that because a similar substance is authorized, their substance must also be approved. This is incorrect. The FDA evaluates each substance individually. A minor difference in chemical structure, impurity profile, or manufacturing process can require a separate FCN.
Negative Outcome: Using an unauthorized substance renders food products adulterated under 21 U.S.C. 342, exposing the company to enforcement action.
Mistake 2: Relying on Another Company’s FCN
FCNs are proprietary. Under Section 409(h)(2)(C) of the FD&C Act, a notification is effective only for the manufacturer identified in the FCN. Competitors cannot use another company’s FCN to market their own version of the substance.
Negative Outcome: Products containing the unauthorized substance can be seized, and the company may face civil penalties up to $250,000.
Mistake 3: Incomplete Migration Testing
Submitting FCNs with insufficient migration data is a common reason for deficiency letters. The FDA requires testing under conditions that simulate actual use, including appropriate temperatures, time intervals, and food simulants.
Negative Outcome: FDA will request additional testing, extending the review period and delaying market entry.
Mistake 4: Ignoring Environmental Requirements
Every FCN must include either a valid categorical exclusion claim or a full environmental assessment. Many notifiers underestimate this requirement, leading to deficiency letters.
Negative Outcome: Incomplete environmental documentation will result in FDA requests for additional information, delaying the review.
Mistake 5: Failing to Calculate Cumulative Exposure
The FDA considers cumulative estimated daily intake (CEDI) from all sources of the substance, not just the new application. Notifiers must add their EDI to any existing CEDI for the substance.
Negative Outcome: Underestimating exposure can lead to insufficient toxicology data, resulting in an FDA objection.
Do’s and Don’ts for Form 3480
| Do’s | Why |

What Happens If You Don’t File?
Failing to file Form 3480 when required can trigger serious legal and business consequences.
A food contact substance that is not authorized under an FCN, food additive regulation, GRAS determination, or TOR exemption is considered an unapproved food additive. Any food that contacts an unapproved FCS is deemed adulterated under 21 U.S.C. 342(a)(2)(C).
Under the Federal Food, Drug, and Cosmetic Act, the FDA can issue warning letters demanding immediate corrective action, seize adulterated products, seek court injunctions prohibiting sale, impose civil penalties of up to $50,000 per individual and $250,000 per company per violation, and pursue criminal prosecution for willful violations.
For imports, the FDA can detain products at the border without physical examination and refuse entry into the U.S. Repeated violations may result in automatic detention of all future shipments.
How FCN Revocation Works
The FDA can determine that an FCN is no longer effective for several reasons.
Under the March 2024 final rule amending 21 CFR 170.105, the FDA may revoke an FCN when new safety data demonstrates the intended use is no longer safe, when the manufacturer or supplier voluntarily abandons production or use of the substance, when the intended use is subsequently authorized by a food additive regulation, or when the substance qualifies for a TOR exemption.
Before revoking an FCN, the FDA must now provide manufacturers an opportunity to respond to safety concerns. Companies have a limited window to provide data or information supporting the continued effectiveness of their FCN.
The inventory of FCNs that are no longer effective is published on FDA’s website. Businesses must monitor this list to ensure they are not using revoked authorizations.
Pre-Notification Consultation (PNC)
For complex submissions or inexperienced notifiers, the FDA offers Pre-Notification Consultations. A PNC allows you to discuss regulatory status questions before submitting an FCN, request pre-review of your safety package, get FDA input on exposure calculations, and clarify testing requirements for your specific application.
To request a PNC, email [email protected] with your questions. For more detailed consultations, you can submit a formal PNC using Form 3480 as an organizing tool.
The FDA recommends PNCs for notifiers unfamiliar with the FCN process. According to FDA’s Office of Food Additive Safety, submissions from inexperienced notifiers are more likely to receive deficiency letters.
Special Considerations
Recycled Materials (PCR)
Using post-consumer recycled (PCR) plastics in food contact applications requires careful FDA evaluation. While FCNs are not specifically required for PCR plastics, companies typically request a No Objection Letter (NOL) from FDA confirming that their recycling process produces material suitable for food contact.
The FDA maintains an inventory of PCR submissions with approved processes. However, if adjuvants in the PCR material are not authorized for food contact, an FCN may still be necessary.
Antimicrobial Substances
Food contact substances with antimicrobial properties face additional scrutiny. According to FDA officials, the definition of FCS can be problematic for antimicrobials because the statute excludes substances intended to have a technical effect in food.
If an antimicrobial migrates to food and affects bacteria in the food (rather than just on the packaging surface), it may be considered a direct food additive rather than an FCS, requiring different regulatory treatment.
Bioplastics and Novel Materials
Innovative materials like PLA, PBS, and PHA bioplastics may or may not require FCNs depending on their composition. Bio-based versions of existing polymers (such as bio-PET) may fit within existing food additive regulations if they meet compositional requirements.
Truly novel biopolymers with no regulatory precedent will require FCN submissions.
FAQs
Does FDA charge a fee for Form 3480 submissions?
No. Unlike drug and medical device submissions, the FDA does not charge user fees for FCN submissions. Costs are limited to data generation and preparation.
Can I submit Form 3480 electronically?
Yes. Electronic submission through the FDA’s Electronic Submission Gateway is strongly recommended and facilitates faster processing.
What happens if FDA objects to my FCN?
The FCN does not become effective. You cannot market the substance. You must address FDA’s concerns and may need to resubmit.
Can I sell my FCN to another company?
No. FCNs are proprietary and non-transferable. Another company must file their own FCN for the same substance.
Is Form 3480 required for substances already in 21 CFR?
No. If your substance and use are covered by existing regulations in 21 CFR Parts 174-178, no FCN is needed.
How long does FDA review take?
120 days maximum by statute. However, deficiency letters can extend this timeline significantly.
Can an effective FCN be revoked?
Yes. FDA can determine an FCN is no longer effective for safety reasons, abandonment, or regulatory supersession.
Do I need Form 3480 for a GRAS substance?
No. Substances properly determined to be GRAS for food contact use are excluded from the food additive definition.
What if my supplier’s FCN is revoked?
You must stop using the substance from that supplier until a new authorization is obtained.
Is Form 3480 required for food processing equipment?
Yes, if applicable. Substances migrating from equipment to food are FCSs and require authorization, including potentially an FCN.
