FDA Form 3480 is the required submission document for notifying the U.S. Food and Drug Administration about a new food contact substance (FCS) or a new use of an existing FCS. Under Section 409(h) of the Federal Food, Drug, and Cosmetic Act, manufacturers or suppliers must complete this form before marketing any substance that contacts food—including packaging materials, coatings, adhesives, plastics, and processing aids. Failure to submit a proper Food Contact Notification (FCN) creates an illegal marketing situation where the FDA considers your product an unapproved food additive, which can result in product seizures, import refusals, and warning letters.
The FCN program has become the primary pathway for food contact substance approvals, with over 1,000 clearances issued since 2000. Unlike the older Food Additive Petition process that took 2-4 years, the FCN process operates on a 120-day timeline—but this clock only starts after FDA accepts your complete submission.

✅ Do’s, Don’ts, and FAQs that answer the most-asked questions about Form 3480
What Is FDA Form 3480 and Who Needs to File It?
FDA Form 3480 serves as the organizing framework for a Food Contact Notification submission. The form collects administrative details about the notifier, chemistry information about the substance, toxicology data supporting safety, and environmental impact documentation.
A food contact substance includes any material intended for use as a component of materials that manufacture, pack, package, transport, or hold food—without having a technical effect on the food itself. This covers plastics, polymers, paper coatings, adhesives, antimicrobials, colorants, and processing aids.
| Who Must File | Who Does Not Need to File |
|---|---|
| Manufacturers introducing a new FCS to the market | Farms using traditional food handling equipment |
| Suppliers seeking clearance for an existing FCS with a new use or new manufacturer | Retail food establishments (restaurants, grocery stores) |
| Companies using substances not already listed in 21 CFR Parts 175-178 or with effective FCNs | Companies using substances already cleared for the exact intended use by the same manufacturer |
The critical distinction is that FCN clearances are proprietary. According to FDA regulations, an FCN is only effective for the specific manufacturer identified in the notification. If Company A receives an FCN clearance for Antioxidant X, Company B cannot market an identical Antioxidant X under Company A’s clearance—Company B must file its own FCN.
The Six Parts of FDA Form 3480: Section-by-Section Instructions
Part I: General Information
Part I captures administrative details about your submission. You must complete every field accurately because errors here delay your 120-day review clock.
Item 1 – Submission Date: Enter the date you transmit the submission to FDA using the YYYY-MM-DD format. If you include a cover letter, these dates must match. For example, enter “2026-01-31” rather than “January 31, 2026.”
Item 2 – Virus Check Confirmation: For electronic submissions, check the box confirming you scanned all files with updated antivirus software. FDA will not process submissions containing infected files.
Item 3 – Mode of Transmission: Indicate whether you submit through the Electronic Submission Gateway (ESG) or via courier/mail. Specify the format (CD-ROM, DVD, or paper) and number of copies. Paper submissions require five complete copies, each with all attachments and a signed Form 3480.
Notifier Information: Provide the complete name, address, phone number, and email of the person or company submitting the FCN. This is the party who receives FDA correspondence and bears legal responsibility for the notification.
Manufacturer/Supplier Information: List every manufacturer whose FCS production is covered by this notification. Remember: the FCN becomes effective only for manufacturers listed here. If you omit a manufacturing site, products from that site have no FDA clearance.
Part II: Chemistry Information
Part II forms the technical backbone of your FCN. This section demonstrates what your substance is, how it is made, and how much migrates into food. FDA reviewers spend significant time analyzing this section because incomplete chemistry data is the most common reason for FCN nonacceptance.
Section A – Chemical Identity
Provide the full chemical name using Chemical Abstracts Service (CAS) nomenclature or International Union of Pure and Applied Chemistry (IUPAC) naming conventions. Do not use trade names or code numbers alone.
Required identity information includes:
- Chemical name and CAS Registry Number (format: 12367-78-9)
- Molecular formula and structural formula
- Molecular weight (for discrete substances) or molecular weight distribution (for polymers)
- Characterizing spectra (IR, NMR, GC-MS)
- Quality control specifications
For polymers, you must also describe the monomer composition, degree of polymerization, and any cross-linking agents.
Section B – Manufacturing Process
The FCN is effective only for products manufactured as described. Any substantive change to your manufacturing process requires a new FCN because different processes create different impurity profiles.
Your manufacturing summary must include:
- All reaction inputs (monomers, catalysts, initiators)
- Processing aids and solvents
- Amounts of each component per batch (e.g., “5 kg monomer per 1000 kg batch”)
- Intended function of each substance
- Process conditions (temperatures, pressures, reaction times)
Section C – Impurities and Specifications
List every substance that may remain in the finished FCS, including:
- Residual monomers
- Reaction catalysts
- Processing aids and solvents
- Reaction byproducts
- Oligomers (for polymeric FCS)
For each impurity, provide analytical data showing maximum concentration levels. Use analytical methods with proper calibration and validation documentation. FDA recommends testing multiple production batches to demonstrate consistency.
Section D – Intended Use and Technical Effect
Define precisely how your FCS will contact food. The FDA’s Food Types table categorizes foods into nine types:
| Food Type | Description | Example Foods |
|---|---|---|
| Type I | Nonacid, aqueous (pH > 5.0) | Vegetables, meats |
| Type II | Acid, aqueous | Tomatoes, citrus juices |
| Type III | Aqueous with free oil/fat | Mayonnaise, salad dressings |
| Types IV-A/B | Dairy products | Butter, milk, cheese |
| Type V | Low-moisture fats/oils | Vegetable oils, lard |
| Types VI-A/B/C | Beverages | Soda, wine, spirits |
| Types VII-A/B | Moist bakery products | Bread, cakes |
| Type VIII | Dry solids, no free fat | Cereals, flour |
| Type IX | Dry solids with free fat | Crackers, chips |
Also specify temperature conditions using FDA’s standard designations (Condition A through H), which range from room temperature to high-temperature processing conditions.
Section E – Stability
Demonstrate your FCS remains chemically stable under intended use conditions. If the substance hydrolyzes, oxidizes, or thermally degrades, you must:
- Identify all degradation products
- Quantify maximum degradation product concentrations
- Include these products in your migration and safety assessments
Section F – Migration Levels
Migration testing quantifies how much FCS transfers from packaging into food. FDA’s Chemistry Recommendations guidance details acceptable testing protocols.
Table 4 in Section F summarizes your migration data. Include:
- Test sample formulation
- Migrant(s) identified
- Food or food simulant used (10% ethanol, 3% acetic acid, food oil)
- Temperature and time conditions
- Migration values for each replicate
- Average migration
Section G – Estimated Daily Intake (EDI)
Calculate the EDI using the formula:
EDI = Migration Value × Consumption Factor × Food Conversion
FDA provides consumption factors that account for the fraction of the daily diet contacting specific packaging types. For single-use packaging, combine migration values with these factors to estimate dietary concentration (DC) in parts per billion (ppb).
Also calculate the Cumulative Estimated Daily Intake (CEDI) by adding your EDI to any existing dietary exposures from the FDA’s CEDI database. The CEDI determines your toxicology testing requirements.
Part III: Safety Information
Part III demonstrates your FCS is safe for human consumption at estimated exposure levels. FDA’s Toxicology Recommendations guidance specifies minimum testing based on CEDI thresholds.
Section A – Safety Narrative
The Safety Narrative summarizes your entire safety case in 2-3 pages. Address:
- Estimated human exposure (EDI and CEDI)
- Summary of toxicity findings
- Conclusions about mutagenic/carcinogenic potential
- Acceptable Daily Intake (ADI) calculation with justification
- Discussion of any unfavorable data
Section B – Comprehensive Toxicology Profile (CTP)
The CTP provides detailed summaries of all relevant safety studies. Organize by study type:
| CEDI Threshold | Required Studies |
|---|---|
| ≤ 0.5 ppb | No testing required; submit available carcinogenicity information |
| > 0.5 ppb to ≤ 50 ppb | Two genotoxicity tests: bacterial mutation + mammalian cell assay |
| > 50 ppb to < 1 ppm | Three genotoxicity tests + two subchronic oral toxicity studies (rodent and non-rodent) |
| ≥ 1 ppm | Submit Food Additive Petition instead (FCN generally not appropriate) |
For biocides (antimicrobials), apply thresholds at one-fifth the standard values because these substances are inherently toxic by design.
Section C – Relevant Toxicity Studies
List all studies supporting your safety determination. Include full study reports for pivotal studies, especially those used to calculate NOELs (No-Observed-Effect Levels) and ADIs. Studies must follow Good Laboratory Practice (GLP) regulations under 21 CFR Part 58.
Part IV: Environmental Information
Every FCN must include either an Environmental Assessment (EA) or a claim of categorical exclusion under 21 CFR 25.32.
Most FCNs qualify for categorical exclusion. Common exclusions include:
| CFR Section | Applies When |
|---|---|
| 21 CFR 25.32(i) | FCS is component of paper/paperboard at <5% by weight and stays with finished product |
| 21 CFR 25.32(j) | FCS is component of repeat-use or permanent food-contact surface |
| 21 CFR 25.32(k) | FCS is component of single-use packaging |
| 21 CFR 25.32(q) | FCS is EPA-registered antimicrobial |
| 21 CFR 25.32(r) | Action does not increase FCS introduced into environment |
If no exclusion applies, you must prepare a full EA discussing environmental fate, disposal impacts, and alternatives.
Part V: Certification
An authorized official must sign Part V certifying the submission is complete, accurate, and submitted in good faith. Indicate whether the signer is:
- The owner, operator, or agent in charge; or
- An individual authorized to submit on behalf of the owner/operator
Include the signer’s name, title, and date. Electronic signatures must comply with 21 CFR Part 11.
Part VI: List of Attachments
Organize all supporting documents using FDA’s folder structure:
| Folder | Contents |
|---|---|
| Administrative | Form 3480, cover letter, confidentiality claims, redacted copies |
| Chemistry | Identity specs, manufacturing description, purity data |
| Chemistry/Studies | Migration studies, stability studies with raw data |
| Safety | Safety narrative |
| Safety/[Chemical Name] | CTP for each substance |
| Safety/[Chemical Name]/Studies | Full study reports by type |
| Environmental | EA or categorical exclusion documentation |
Three Real-World Scenarios: Filling Out Form 3480
Scenario 1: Polymer Manufacturer Filing for New Plastic Packaging
Situation: A plastics company develops a new bio-based polymer (PEF) for food packaging and needs FCN clearance.
| Step | Action Required |
|---|---|
| Identify all monomers and catalysts | List FDCA, ethylene glycol, and titanium catalyst with CAS numbers |
| Complete manufacturing description | Document polymerization conditions, purification steps, oligomer removal |
| Conduct migration testing | Test in aqueous, acidic, alcoholic, and fatty food simulants at temperatures covering intended use |
| Calculate CEDI | Sum migration EDI with any existing dietary exposures from similar polymers |
| Perform toxicology studies | Based on CEDI (likely 0.5-50 ppb range), submit genotoxicity battery |
| Claim categorical exclusion | Cite 21 CFR 25.32(k) for single-use packaging |
When Avantium obtained FCN clearance for PEF, the approval covered all food types except infant formula, human milk, and beverages with >15% alcohol—demonstrating how intended use limitations appear in final clearances.
Scenario 2: Additive Supplier Seeking Clearance for Antioxidant Use in LDPE
Situation: A chemical company wants clearance for its antioxidant (“Adjuvant X”) at 0.01 wt.% in low-density polyethylene packaging.
| Step | Action Required |
|---|---|
| Define intended use | Specify 0.01 wt.% maximum in LDPE contacting all food types at Conditions B and C |
| Test migration from LDPE films | Prepare test plaques at maximum use level; extract in 10% ethanol and oil simulants |
| Document stability | Show antioxidant remains stable during film processing and storage |
| Calculate EDI/CEDI | Use packaging consumption factor (CF = 0.1-0.8 depending on food type) |
| Address impurities | Quantify residual starting materials and any decomposition products |
| Complete toxicology | Submit genotoxicity data if CEDI > 0.5 ppb |
Scenario 3: Paper Coating Manufacturer Filing for Grease-Resistant Treatment
Situation: A specialty chemical company creates a fluorine-free coating for food paperboard and needs FDA clearance.
| Step | Action Required |
|---|---|
| Fully characterize coating | Provide polymer identity, molecular weight distribution, unreacted monomer levels |
| Specify paperboard application | Maximum coating weight per unit area, single-side vs. double-side application |
| Conduct extraction studies | Test under conditions simulating grease contact (vegetable oil, 40°C) |
| Address current regulatory landscape | Note that many PFAS-based coatings have been voluntarily withdrawn |
| Claim appropriate exclusion | If coating <5% of dry paper weight, cite 21 CFR 25.32(i) |
| Reference safety data | Submit toxicology on coating polymer and any monomers with CEDI > 0.5 ppb |
Common Mistakes to Avoid When Filing Form 3480
Understanding common filing errors helps you avoid rejection. FDA does not accept incomplete notifications, and deficiencies restart your review timeline.
Mistake 1: Missing or Incorrect Manufacturer Information
Problem: Listing only the notifier company without identifying all manufacturing facilities.
Consequence: FCN clearance covers only manufacturers named in the notification. Products from unlisted sites remain unapproved food additives. You must file a new FCN for each additional manufacturer.
Mistake 2: Using Trade Names Instead of Chemical Names
Problem: Identifying substances by proprietary names like “Stabilizer ABC-100” without providing CAS numbers or systematic chemical names.
Consequence: FDA cannot verify chemical identity or search existing databases. Your FCN will receive a nonacceptance letter requesting proper identification.
Mistake 3: Incomplete Migration Data
Problem: Testing migration only in aqueous simulant when the intended use includes fatty foods.
Consequence: FDA cannot evaluate safety for all intended uses. You must repeat migration testing in appropriate simulants, delaying clearance by months.
Mistake 4: CEDI Calculation Errors
Problem: Failing to include existing dietary exposures when calculating cumulative intake.
Consequence: Underestimating CEDI may result in insufficient toxicology data. FDA will object if your CEDI actually exceeds the threshold requiring additional studies you did not submit.
Mistake 5: Inadequate Impurity Characterization
Problem: Stating “no significant impurities” without analytical support.
Consequence: FDA requires positive evidence that impurity levels are negligible or safe. Uncharacterized impurities trigger objection letters requesting additional testing.
Mistake 6: Missing Environmental Documentation
Problem: Omitting Part IV entirely or claiming categorical exclusion without citing the specific CFR section.
Consequence: No FCN becomes effective without environmental review. FDA issues nonacceptance for missing environmental documentation.
Mistake 7: Unsigned Certification
Problem: Submitting Form 3480 without signature in Part V or with unauthorized signer.
Consequence: FDA cannot accept unsigned notifications. The entire package must be resubmitted with proper certification.
Do’s and Don’ts for FDA Form 3480
| Do’s | Why It Matters |
|---|---|
| ✅ Consult FDA guidance documents before starting | Guidance documents explain exactly what information FDA expects, reducing rejection risk |
| ✅ Use the Pre-Notification Consultation (PNC) process for complex substances | FDA will review your data package informally and identify gaps before the 120-day clock starts |
| ✅ Test multiple production batches for specifications | Single-batch data may not represent normal production variability |
| ✅ Organize attachments using FDA’s folder structure | Proper organization speeds FDA review and demonstrates professional preparation |
| ✅ Keep redacted and non-redacted versions consistent | Inconsistencies raise questions about what information you consider confidential |
| Don’ts | Why It Matters |
|---|---|
| ❌ Assume your substance qualifies for FCN without checking CEDI | If cumulative exposure ≥ 1 ppm, you need a Food Additive Petition instead |
| ❌ Reference another company’s FCN for your manufacturing | Each manufacturer needs its own FCN—the clearance is proprietary |
| ❌ Submit without complete GLP-compliant studies | Non-GLP studies for pivotal safety determinations require independent audits and explanations |
| ❌ Claim categorical exclusion without supporting documentation | FDA verifies exclusion claims; unsupported claims cause delays |
| ❌ Change manufacturing after clearance without new FCN | Substantive manufacturing changes require new notifications |
Pros and Cons of the FCN Process
| Pros | Explanation |
|---|---|
| ✅ Fast timeline (120 days) | FCN clearance takes 4 months vs. 2-4 years for Food Additive Petitions |
| ✅ Proprietary clearance | Competitors cannot use your clearance—provides market exclusivity |
| ✅ No user fees | Unlike drug approvals, FDA charges no fees for FCN review |
| ✅ Electronic submission available | ESG submission is faster than mailing physical copies |
| ✅ Flexible data package | You can reference Food Master Files for confidential third-party data |
| Cons | Explanation |
|---|---|
| ❌ Clearance is manufacturer-specific | Each manufacturing site needs separate clearance, multiplying filings |
| ❌ No FDA approval letter | FCN becomes effective by default unless FDA objects—some companies prefer explicit approval |
| ❌ Significant upfront investment | Comprehensive chemistry and toxicology testing costs $50,000-$200,000+ |
| ❌ 1 ppm CEDI cap | High-exposure substances require the longer petition process |
| ❌ Revocation risk | FDA can declare FCNs no longer effective if new safety data emerges |
Key Entities and Their Roles
FDA Center for Food Safety and Applied Nutrition (CFSAN): Reviews all FCNs through the Office of Food Additive Safety (OFAS). Contact them at 240-402-1175 or submit inquiries to [email protected].
Notifier: The company or individual submitting the FCN. Bears legal responsibility for accuracy and receives all FDA correspondence.
Manufacturer/Supplier: The entity producing the FCS. Only manufacturers listed in an FCN can market the substance under that clearance.
U.S. Agent (for foreign manufacturers): Foreign companies submitting FCNs must designate a U.S. agent to receive FDA communications.
FAQs
Can I use FDA Form 3480 for substances already regulated under 21 CFR Parts 175-178?
No. FDA may decline to accept FCNs for substances already having effective regulations or exemptions. Review existing regulations before filing.
Does FDA charge fees for reviewing FCN submissions?
No. The FCN program operates without user fees. However, you incur costs for testing, preparation, and professional consulting.
Can multiple manufacturers share one FCN clearance?
No. Each manufacturer needs identification in the FCN. However, one notification can list multiple manufacturing sites for the same notifier company.
How long does FDA take to acknowledge an FCN?
Yes, FDA aims to acknowledge within 30 days. The acknowledgment confirms receipt date and describes the FCS and intended use for the official record.
Can I withdraw an FCN after submission?
Yes. You can withdraw without prejudice anytime before FDA completes its 120-day review. Withdrawn FCNs remain confidential and do not affect future submissions.
Does an effective FCN mean FDA approves the substance?
No. FCNs become effective by default unless FDA objects. The absence of objection is not the same as affirmative FDA approval or endorsement.
Can I file an FCN and a Food Additive Petition simultaneously?
No. Filing both simultaneously for the same use is prohibited under 21 CFR 170.100. Choose one pathway.
Must I conduct animal testing for every FCN?
No. If your CEDI is ≤ 0.5 ppb, no new toxicity testing is required—only available carcinogenicity information. Testing requirements scale with exposure level.
Can FDA revoke an effective FCN?
Yes. Under 21 CFR 170.105, FDA can determine an FCN is no longer effective for safety reasons or if the manufacturer abandons use.
What happens if FDA objects to my FCN?
Yes, you receive a written objection letter explaining deficiencies. You can submit a new FCN addressing those issues, request a meeting, or pursue a Food Additive Petition if appropriate.
