If your packaging supplier lists “FSC certified” on their website, it’s worth understanding exactly what that means before you rely on it in your own marketing. FSC certification is one of the most commonly cited sustainability claims in packaging sourcing, but it is also frequently misunderstood — or, in some cases, misused. This guide explains what FSC certification actually covers, the different certificate types you’ll encounter, and how to verify a supplier’s claim before you put it on your own packaging or website.
What Is FSC Certification?
The Forest Stewardship Council (FSC) is an independent, non-profit organization that certifies forests and the supply chains that use their wood and paper products. FSC certification confirms that the paper, board or wood fiber in a product can be traced back to responsibly managed forests — meaning harvesting practices meet environmental, social and economic standards set by the FSC.
For packaging specifically, FSC certification matters at two levels: the raw material (the paperboard or corrugated stock itself) and the manufacturing facility (which must hold FSC Chain of Custody certification to legally print the FSC logo on finished packaging).
The Three Types of FSC Claims
Not all FSC-labeled packaging is the same. There are three distinct claim types, and the difference matters for how you can describe your packaging to customers.
- FSC 100% — the material comes entirely from FSC-certified forests.
- FSC Mix — the material is a blend of FSC-certified, recycled, and/or controlled wood sources. This is the most common claim for commercial packaging.
- FSC Recycled — the material is made entirely from reclaimed or recycled wood/paper fiber.
Each claim type has its own on-pack labeling rules. A supplier printing “FSC 100%” on packaging that actually uses FSC Mix stock is misrepresenting the claim, which can create compliance risk for your brand if a retailer or regulator checks.
Why FSC Certification Matters for Your Brand
If you sell into the EU or UK, FSC certification is increasingly close to a baseline expectation rather than a differentiator. Major retailers require it for private-label packaging, and EU packaging regulation is pushing brands toward verifiable, traceable material sourcing rather than vague “eco-friendly” claims. Beyond compliance, an unverified or incorrect FSC claim is a reputational risk — greenwashing scrutiny has increased, and customers or auditors can check certificate numbers directly.
How to Verify a Supplier’s FSC Certificate
- Ask for the supplier’s FSC Chain of Custody (CoC) certificate number.
- Check the number against the FSC public database to confirm it is active and registered to that company.
- Confirm which claim type (100%, Mix, or Recycled) their certificate actually covers for the product you’re ordering.
- Ask whether the certificate covers the specific facility producing your order, since some manufacturers operate multiple facilities under separate certificates.
A legitimate supplier will provide their certificate number without hesitation. Reluctance to share it, or a certificate that doesn’t match the company name on your contract, is a red flag worth investigating before you commit to production.
FSC Certification vs Other Sustainability Claims
FSC certification is specific to wood and paper fiber sourcing. It does not cover other sustainability claims like “biodegradable,” “plastic-free,” or “recyclable” — those require separate substantiation. If your packaging combines FSC-certified board with plastic components, coatings or laminates, you’ll need to evaluate each material separately. For a broader view of sustainable sourcing beyond FSC, see our guide on eco-friendly packaging from China, and if you’re sourcing for the EU market specifically, our PPWR compliance guide covers how material claims interact with the EU’s newer packaging waste regulation.
Questions to Ask Before You Order
- Can you provide your current FSC Chain of Custody certificate number?
- Which FSC claim (100%, Mix, Recycled) applies to the specific board or paper I’m ordering?
- Does your certificate cover the exact facility that will produce my order?
- Can the FSC claim be printed on-pack, and do you handle the labeling compliance for that?
- Is there a cost difference between FSC-certified and non-certified stock for my order?
FAQ
Does FSC certification cost more?
Usually a modest premium over non-certified stock, since certified suppliers pay for audits and chain-of-custody tracking. The cost difference varies by material and region, so ask your supplier for a direct comparison on your specific order.
Can I put the FSC logo on my packaging myself?
No. Only companies holding a valid FSC Chain of Custody license can authorize use of the FSC trademark, and there are specific rules for how the logo and claim must be printed. Your packaging manufacturer or a licensed intermediary needs to manage this on your behalf.
Is FSC certification required to sell in the EU?
Not universally required by law for all products, but many retailers, marketplaces and private-label programs now mandate it as a condition of listing. Regulatory pressure under EU packaging and deforestation rules is also increasing its practical importance.
Caiye Packaging holds FSC Chain of Custody certification alongside ISO 9001 and BSCI, which you can see on our About page. If you’re sourcing packaging for a market that requires verified sustainable material claims, get in touch with our team and we can confirm exactly which FSC claim applies to your product and share our current certificate for verification.
