Can private label sellers use supplier certificates?

Private label sellers can use their supplier’s underlying test reports and technical files, but they cannot use the supplier’s actual Certificates or Declarations of Conformity once their own brand logo is placed on the product.

The moment you put your own brand name or trademark on an item, EU law legally defines you as the manufacturer. This means your supplier’s certificates stop covering your business, and you must issue new compliance paperwork under your own company name.

The Legally Compliant Setup:

To leverage a factory’s existing testing without paying for completely new, redundant lab evaluations, private label sellers must use a specific documentation pipeline:

1. Obtain the Factory Technical File: Your contract must require the supplier to share their raw lab test reports and product data.
2. Review for Accuracy: You must verify that the test reports are from an accredited laboratory, are up to date, and explicitly match your product’s specifications and model numbers.
3. Issue Your Own Declaration of Conformity (DoC): You must draft and sign a new DoC that bears your private label brand name, your business address, and the specific product identifiers.
4. Compile the Master Technical File: Store the supplier’s test reports together with your new DoC, your own risk assessment, and your branded user manuals. Keep this file for 10 years.

Critical Friction Points & Failure Risks:

• The Name Mismatch (Amazon & Customs Seizures): If a customs official or an e-commerce platform like Amazon audits your listing, they will flag a certificate that displays a Chinese factory’s name when the product box displays your private label brand name.
• Supplier Data Redaction: Many original equipment manufacturers (OEMs) refuse to share raw test reports because they want to protect their proprietary designs or factory source information. If they will not give you the test reports, you cannot build a legal technical file.
• Contracts Do Not Move Liability: You cannot bypass manufacturer status by writing a clause in your supplier agreement stating that the factory is responsible for legal claims. National regulators will fine and hold the brand named on the packaging legally liable.
• New 2026 Packaging Regulations (PPWR): Under the EU Packaging and Packaging Waste Regulation (PPWR) that took effect on August 12, 2026, private labelers are also fully deemed the “manufacturer” of the packaging itself. You must issue a separate DoC covering the recycling and minimization design of the box your product arrives in.

Alternative: How to Avoid Becoming the Manufacturer:

If you do not want to take on full manufacturer liability and paperwork, you must pivot away from private labeling:

• Sell the item as a Factory Brand. Leave the original manufacturer’s brand name, logo, packaging, and model numbers exactly as they are.
• Act strictly as the Importer (if sourcing from outside the EU) or Distributor (if sourcing from inside the EU). This permits you to legally rely on the supplier’s certificates.
