Cosmetic labeling is one of the most visible and heavily regulated aspects of product compliance in the United States. Among all label components, the Principal Display Panel (PDP) carries special regulatory importance. The PDP is the portion of the cosmetic package that consumers see first, and it must present essential information in a clear, accurate, and compliant manner.
Under the authority of the US FDA, and reinforced by the Modernization of Cosmetics Regulation Act (MoCRA), improper or incomplete Principal Display Panels can cause a cosmetic product to be considered misbranded, making it illegal to sell in the United States.
XPRO America is a professional US FDA Consultancy helping cosmetic brands design, review, and validate Principal Display Panels that meet regulatory expectations.
What Is the Principal Display Panel
The Principal Display Panel is the part of a cosmetic package that is most likely to be displayed or examined by consumers at the time of purchase.
It is commonly:
- The front panel of a bottle
- The main face of a carton
- The most prominent label surface
The PDP is where key product identity and quantity information must appear.
Why the Principal Display Panel Is Regulated
The purpose of PDP regulation is to ensure that consumers can immediately understand:
- What the product is
- How much product they are buying
The US FDA evaluates the PDP to determine whether the product is presented in a truthful, non-misleading, and standardized manner.
A deficient PDP can result in:
- Misbranding findings
- Warning letters
- Import refusal
- Mandatory recalls under MoCRA
Mandatory Elements on the Principal Display Panel
Two elements are required on the PDP for cosmetic products:
- Statement of Identity
- Net Quantity of Contents
Both must be clearly visible and prominent.
Statement of Identity
The statement of identity tells consumers what the product is.
Examples:
- Face Cream
- Shampoo
- Body Lotion
- Lipstick
- Hair Serum
Key Rules
- Must be in plain, descriptive language
- Must accurately describe product type
- Must appear on the PDP
Brand names alone are not sufficient. For example, “Glow Beauty” does not tell the consumer what the product actually is.
Placement and Size
The statement of identity must:
- Be placed on the PDP
- Be in a type size reasonably related to the most prominent printed matter
If the product has multiple functions, the primary function should be stated.
Net Quantity of Contents
The net quantity statement tells consumers how much product is inside the package.
Required Units
The net quantity must be declared in:
- US customary units (oz, fl oz, lb)
- Metric units (g, mL)
Both units must appear.
Example:
Net Wt. 3.4 oz (96 g)
Net Contents 8 fl oz (237 mL)
Measurement Basis
Net quantity must reflect:
- Weight for solids
- Volume for liquids
- Count for items sold by number
It must represent only the cosmetic product, not the container.
Placement Rules
The net quantity statement must:
- Appear on the PDP
- Be placed in the lower 30% of the PDP
- Be parallel to the base of the package
Incorrect placement is a common violation.
Language and Legibility Requirements
All PDP information must:
- Be in English
- Be easy to read
- Have sufficient contrast with background
- Not be hidden or obscured
Overly decorative fonts or poor color contrast may be considered non-compliant.
PDP and Misbranding Risk
A cosmetic is considered misbranded if:
- The PDP is missing required information
- The product identity is unclear
- The net quantity is missing or incorrect
- The information is misleading
Misbranding makes a cosmetic illegal to distribute in the US.
PDP vs. Information Panel
It is important to distinguish between:
- Principal Display Panel – front-facing key information
- Information Panel – ingredients, Responsible Person name/address, warnings
Only the product identity and net quantity are required on the PDP.
PDP for Small Packages
Small cosmetic packages may face space limitations.
However:
- PDP requirements still apply
- Abbreviations must be standard
- Information must remain legible
XPRO America evaluates small-package labeling for compliance.
PDP and MoCRA Compliance
MoCRA strengthens US FDA authority to:
- Review labels during inspections
- Access records supporting label claims
- Mandate recalls of misbranded cosmetics
The PDP must align with:
- Cosmetic product listing
- Safety substantiation
- Label ingredient declaration
- Responsible Person identification
Inconsistencies raise regulatory red flags.
Import Considerations
Imported cosmetics with incorrect PDPs may be:
- Detained at port
- Refused entry
- Placed on import alert
Pre-export PDP review is strongly recommended.
Common PDP Mistakes
- Brand name used instead of product identity
- Missing net quantity statement
- Only metric or only US units provided
- Net quantity placed outside PDP
- Decorative fonts that reduce readability
These errors are easily preventable.
Best Practices for PDP Compliance
- Define clear product identity
- Verify correct unit usage
- Check placement and font size
- Align PDP with formulation and listing
- Perform regulatory label review before printing
- Work with an experienced US FDA Consultancy

Compliance Insight
The Principal Display Panel is the first regulatory checkpoint on any cosmetic label. Even high-quality products can become illegal to sell if the PDP is incorrect. Under US FDA authority and MoCRA enforcement, cosmetic brands must ensure that PDP content is accurate, prominent, and compliant.
