What Certificates Should Cosmetic Packaging Have?

Choosing cosmetic packaging doesn't end with design and functionality. In practice, documentation and regulatory compliance determine whether your product can safely enter the market. However, the topic of certificates still raises plenty of doubts: what is legally mandatory, and what simply provides a competitive advantage? Where does legal compliance end and pure marketing begin? Below, we break down the most essential information.

Certificate vs. Declaration of Compliance—Key Differences and Legal Definitions

In daily business discussions, these terms are often used interchangeably, which breeds a lot of misunderstanding between manufacturers and suppliers. In a legal sense, however, they represent two completely different levels of responsibility and documentation. To organize this knowledge and avoid costly mistakes during audits, it helps to compare both definitions clearly.

Legal Requirements vs. Market Standards in the Cosmetic Industry

Navigating the maze of regulations requires drawing a sharp line between what the law strictly mandates and what consumers or retail chains expect. Without meeting hard legal standards, your product will never make it to shelves. Conversely, a lack of market certificates can drastically narrow your pool of potential buyers.

The Minimum Compliance Package (Must-Have)

Every piece of packaging used to store your formulas falls under Regulation (EC) No 1223/2009 of the European Parliament and of the Council on cosmetic products. From a safety assessor's perspective, the most critical part is Article 17, which addresses the purity of substances and the absence of prohibited ingredients migrating into the cosmetic bulk. Trace amounts may appear due to migration from packaging, provided their presence is technologically unavoidable and does not impact product safety.

The component supplier must provide proof that the packaging does not react with the formulation, does not leach harmful substances (such as heavy metals), and shields the product from external factors.

For plastics, the foundational benchmarks are Regulation (EC) No 1935/2004 and Commission Regulation (EU) No 10/2011. Although originally created for the food sector, they are universally used as the reference point for plastic safety assessments in cosmetics.

Building a Competitive Advantage (Nice-to-Have)

Once you have covered your legal bases, it is time to think about brand positioning. This is where market standards come into play. If your manufacturing brand centers its communication on naturality, certificates like Cosmos (Ecocert) or NaTrue for the packaging itself become incredibly powerful sales arguments.

Certain retail networks may also require cosmetic brands to prove their containers hold a Vegan Society certification (confirming no animal-derived components were used during raw material production) or certificates validating dermatological safety.

Systemic and Quality Certificates on the Manufacturer's Side

A supplier's credibility is built on the standards by which they manage their factory. When buying components, you should always ask about implemented quality management systems.

• ISO 9001: The absolute baseline. It confirms that the manufacturer operates under a structured quality management system, which translates to better batch-to-batch repeatability and lower defect rates.
• ISO 22716: This standard details Good Manufacturing Practices (GMP) specifically for cosmetics.
• ISO 15378: Developed for primary packaging materials for medicinal products. While it doesn't formally govern the cosmetic sector, many high-end packaging manufacturers use it to demonstrate an elite level of quality control, traceability, and production process management.

Ecological Certificates for Raw Materials

The circular economy transition forces the industry to look closely at the origins of plastics and paper. “Greenwashing”—making baseless eco-friendly claims—has become rampant. To protect your brand and legally boast green labels, you must demand hard evidence from your suppliers.

For renewable resources like paper or wooden caps, FSC (Forest Stewardship Council) or PEFC remain the golden standard, proving the cellulose comes from responsibly managed forests. If you are introducing recycled plastic (PCR) into your portfolio, look for ISCC Plus (International Sustainability and Carbon Certification) or RecyClass certifications. These track the supply chain and verify the exact percentage of recycled material used.

How to Match the Right Certificates to a Specific Packaging Material

Every material exhibits distinct physicochemical characteristics, meaning your documentation checklist must adapt based on the raw material chosen.

Glass Packaging

Glass is considered the safest and most chemically inert material. However, this does not mean you can let your guard down. When choosing glass, the key parameter is the hydrolytic class (typically Type III for cosmetics). Demand compliance with ISO 719 or ISO 4802, which confirms the glass's resistance to water and prevents the leaching of alkalis into the formulation. This is absolutely critical for water-based formulas like toners or mists, where a shift in pH could ruin an entire production batch.

Plastic Packaging

Plastics (PET, PP, HDPE) require the most extensive documentation. Ensure your packaging partner supplies Declarations of Compliance with Regulation 10/2011 alongside global and specific migration test reports. A safety assessor will ruthlessly check for the presence and migration of heavy metals, plasticizers, and phthalates. If you are opting for rPET, double-check if the recycling process holds a positive opinion from the EFSA (European Food Safety Authority).

Aluminum Packaging

Aluminum enjoys massive popularity in the premium and eco-friendly segments. However, raw aluminum reacts with many cosmetic formulas (especially those with extreme pH levels). Because of this, the internal protective coating (lacquer) is the most important element of an aluminum bottle or tube. Verify its composition and ensure the manufacturer has documentation regarding the presence or absence of substances raising regulatory concerns, such as Bisphenol A (BPA).

Paper Packaging

For paper and cardboard, pay attention to declarations regarding the used inks, varnishes, and glues. Where necessary, gather data on the content and migration of compounds like MOSH/MOAH (mineral oil hydrocarbons), which could potentially migrate through primary packaging into the cosmetic mass.

Supplier Documentation—Which Statements and Test Reports to Collect?

Let’s talk pure operational practice. When compiling documentation for the Cosmetic Product Safety Report (CPSR), your binder should contain a concrete set of signed papers from your quality department and packaging partner. General verbal assurances from a salesperson won't cut it.

Here is your essential checklist:

• Technical Data Sheet (TDS): Outlining exact dimensions, tolerances, weight, and material specifications for every single component (bottle, pump, overcap).
• Declaration of Compliance (DoC): Explicitly referencing European cosmetic legal frameworks or related food-contact regulations.
• SVHC Statement (REACH): Confirming that the packaging contains no Substances of Very High Concern in a concentration exceeding 0.1%.
• Migration Test Reports: Most common for plastics, detailed with results from tests conducted using appropriate food/cosmetic simulants.
• Heavy Metals and Fluorine Declaration: From August 12, 2026, a declaration confirming compliance with the EU Regulation 2025/40 is required. This replaces the old Directive 94/62/EC. The sum of lead, cadmium, mercury, and hexavalent chromium concentrations cannot exceed 100 mg/kg of packaging weight. Furthermore, packaging coming into contact with formulations cannot exceed 25 ppb for a single PFAS compound, 250 ppb for the sum of PFAS, or 50 ppm of total fluorine.

Practical Tip: Waiting to compile these documents until your product is already sitting on the filling line is the most common mistake made by junior procurement teams. Handle these formalities during the sampling and compatibility testing phase. A truly reliable packaging partner will provide you with a full compliance documentation packet before you even finalize your order, giving you absolute control over the entire launch process.
