What is Adverse Event Reporting Under MoCRA?

The Modernization of Cosmetics Regulation Act (MoCRA) made reporting of serious adverse events mandatory for cosmetic products. Under 21 U.S.C. § 364a, the responsible person for a cosmetic product must report serious adverse events to the FDA within 15 business days.

Mandatory Requirement

Adverse event reporting is mandatory for ALL businesses - there is NO small business exemption. Failure to report serious adverse events can result in FDA enforcement action including warning letters, product recalls, or injunctions.

This represents a significant change from pre-MoCRA requirements, when adverse event reporting for cosmetics was voluntary.

What is a Reportable Adverse Event?

Definition of Adverse Event

According to FDA adverse event guidance, an adverse event is any health-related event associated with the use of a cosmetic product. This includes:

  • Skin reactions (rash, irritation, burns)
  • Eye reactions (irritation, swelling, vision changes)
  • Respiratory reactions (breathing difficulties, coughing)
  • Allergic reactions (hives, anaphylaxis)
  • Hair or scalp effects (hair loss, scalp irritation)
  • Any other negative health effect

What Makes an Adverse Event "Serious"?

Under 21 U.S.C. § 364a, a serious adverse event is one that results in:

Serious Adverse Event Criteria
CriterionDescriptionExample
DeathEvent results in deathFatal allergic reaction
Life-threateningImmediate risk of deathAnaphylactic shock
HospitalizationInpatient hospital admissionSevere chemical burns
Persistent disabilityLasting impairmentPermanent scarring
Congenital anomalyBirth defectPrenatal exposure effects
Medical intervention requiredTo prevent serious outcomeEmergency treatment for reaction

Key Point

Only SERIOUS adverse events must be reported to the FDA. Non-serious events should be documented and maintained in your records but do not require FDA submission.

Who Must Report Adverse Events?

Per 21 U.S.C. § 364, the responsible person must report adverse events. This is typically:

  • The manufacturer, packer, or distributor whose name appears on the product label
  • For foreign products, the US Agent may assist but the responsible person remains accountable

Small Business Obligations

According to FDA Guidance for Industry (December 2024):

No Exemption from Reporting

Serious adverse event reporting is mandatory for ALL businesses regardless of size. All businesses must report serious adverse events within 15 business days.

However, small businesses DO receive these accommodations:

  • Reduced record retention: 3 years (vs. 6 years for non-exempt businesses)
  • Exempt from facility registration and product listing (unless manufacturing high-risk products)
  • Exempt from GMP requirements (when finalized)

Small businesses must still:

  • Report serious adverse events within 15 business days
  • Maintain adverse event records (for 3 years)
  • Include product label copy with reports
  • Submit follow-up information within 15 business days if received within 1 year

When Does the Clock Start?

The 15-business-day deadline begins when the responsible person receives information about a serious adverse event. This includes reports received through:

  • Customer service contacts
  • Email or phone complaints
  • Social media mentions (if company monitors)
  • Retailer notifications
  • Healthcare provider communications
  • Distributor reports

How to Submit Adverse Event Reports

Adverse Event Reporting Process

1
Receive and Document the Report

When you receive information about an adverse event, immediately document all details: date received, consumer information, product details, description of event, and any medical treatment sought.

2
Evaluate Seriousness

Determine if the adverse event meets the criteria for a 'serious' adverse event. If it results in death, hospitalization, disability, or requires medical intervention to prevent serious outcomes, it is reportable.

3
Gather Required Information

Collect all required information for the FDA report: product identification, description of the adverse event, patient/consumer information (if available), and any medical records or documentation.

4
Submit to FDA

Submit the report via FDA Form 3500A by email to CosmeticAERS@fda.hhs.gov (recommended) or by mail. Include a copy of the product label with your submission.

5
Maintain Records

Keep copies of all adverse event reports, supporting documentation, and FDA submissions. Records must be retained for 6 years.

6
Submit Follow-Up Information

If new information about the adverse event becomes available within 1 year of the initial report, submit follow-up information to the FDA.

Current Submission Methods (January 2026)

According to FDA guidance, reports should be submitted via:

Primary Method: FDA Form 3500A (MedWatch)

  • Email: CosmeticAERS@fda.hhs.gov
  • Mail: FDA CDER Mail Center, Attn: Cosmetics MedWatch reports, White Oak Campus, Building 22, G0207, 10903 New Hampshire Ave., Silver Spring, MD 20993

Important Updates (September 2025)

- FDA launched FAERS Public Dashboard for Cosmetic Products - Cosmetics adverse event data migrated from CAERS to FAERS - Direct electronic submission through a dedicated cosmetics portal is not yet available - Safety Reporting Portal has not been enabled for cosmetics adverse events - Form 3500A is downloadable and fillable — email submission to CosmeticAERS@fda.hhs.gov is FDA's recommended method

Setting Up an Adverse Event System

3
Develop Evaluation Criteria

Create checklists and criteria for evaluating whether an adverse event is 'serious' under MoCRA. Train staff to identify reportable events.

4
