FSC and PEFC Certified Plywood Explained: Chain of Custody, Claims and How the Schemes Differ

Lay three plywood quotes on a desk and the logos get confusing fast. One has the tick-tree and a code with "COC" in the middle. Another has two little trees in a circle. The third has both, and somebody's typed "Mix" next to the product line on the invoice. They all seem to say the wood was sourced responsibly. They don't all say the same thing, though, and a logo printed on a brochure isn't a claim on your delivery.

We see buyers trip on this more than on almost any other document. So this guide sticks to the basics: what FSC and PEFC each certify, how a claim gets from a plantation to a container, where the two schemes part ways, and what a certificate won't tell you. For the buying angle on film-faced panels specifically, the Vinawood mill covers that in FSC certified film-faced plywood.

Two kinds of certificate, and why the difference matters

There are two layers here, and people blur them all the time. First comes forest management certification. An auditor visits a forest or plantation and checks how it's run: is the harvest legal, are workers treated properly, are streams and soil protected, do local communities keep their rights? That certificate belongs to whoever manages the land, sometimes a group of smallholders pooled together.

Then there's chain of custody, or CoC. Logs leaving a certified plantation don't stay in one pair of hands. They go to a peeler, maybe a veneer trader, then a plywood mill, then possibly an exporter and an importer. Each company that owns the material on the way needs its own CoC certificate showing it tracks certified wood properly and only passes on claims it's allowed to make. Miss one link and, in most cases, the claim ends there.

That's the part that matters to a plywood buyer. A plywood mill doesn't need a forest certificate, because it doesn't manage forest. It needs a live CoC certificate with plywood in its scope, and certified inputs arriving from suppliers who hold their own certificates.

How FSC works

The Forest Stewardship Council writes its own rules, for forests and for chain of custody. Its CoC standard is FSC-STD-40-004, and it spells out how certified companies handle material and what has to show up on sales and delivery paperwork. Certificate codes usually start with a short prefix for the certification body, then "COC", then a number.

Then come the claims, and there are only a few you'll see on plywood. "FSC 100%" means every bit of forest material came from FSC-certified forest. "FSC Recycled" is all reclaimed fibre, which you won't often meet in structural panels. "FSC Mix" is the common one: certified wood blended with recycled material or FSC Controlled Wood, written either as a percentage or as a credit depending on how the mill keeps its books.

Controlled Wood is the odd one out. It isn't from certified forest; it's wood that's been checked to keep out the worst sources, illegal logging included. It can move between certificate holders as an input, but it can't carry an FSC label by itself, and FSC only allows the Controlled Wood claim on documents going to other CoC holders. You can look up any certificate, and what it covers, on FSC Search.

How PEFC works

PEFC, the Programme for the Endorsement of Forest Certification, goes about it differently. It doesn't write one forest standard for the planet. Countries build their own national schemes, PEFC has each one assessed independently with a public consultation, and if it passes, forests certified under it count toward PEFC claims. Every endorsed scheme gets reviewed at least once every five years.

Vietnam's a handy example. Its national scheme, VFCS, was first endorsed by PEFC in 2020, and PEFC says almost 300,000 hectares are now certified under it. A revised VFCS went through the five-year review this year, with public comments closing on 9 October 2026, per PEFC's notice.

For chain of custody, PEFC uses PEFC ST 2002:2020. Its two claims are "x% PEFC certified" and "PEFC controlled sources". There's also "100% PEFC Origin", reserved for certified material that's been kept physically separate and never mixed with controlled sources. PEFC controlled sources is roughly PEFC's version of FSC Controlled Wood: material that a company's due diligence system has rated as negligible risk.

FSC and PEFC side by side

Both lean on third-party audits by accredited bodies. Both split forest management from chain of custody. Where they differ is mostly who writes the forest rules and how the claims read.

Is one better? Not in any way the law cares about. Neither is a legal requirement on its own in the big import markets. Some public clients, green building rating systems and large contractors ask for one, some take either, and it's usually the project spec that decides, not a regulator.

How a claim moves along the supply chain

Take one sheet of plantation-grown eucalyptus plywood. The grower's delivery note to the peeler carries a forest certificate code and a claim. The peeler and the mill both hold CoC certificates, so they can account for that wood and print their own claim and code on the invoice for finished panels. Now say a trading house buys the panels and sells them on. No CoC certificate at the trader? Then as far as the scheme cares, those panels stopped being certified at the trader's door. Nothing about the wood changed. The paper trail did.

So auditors, and smart buyers, read documents rather than logos. The claim has to sit on the sales and delivery papers for your actual shipment, next to the seller's certificate code, and the product has to fall inside that certificate's scope. A PDF of a certificate attached to a quote tells you the company is certified. It doesn't tell you your container was sold as certified.

What certification does not prove

A CoC claim is about where wood came from and how it was tracked. That's all. It won't tell you if the glue line survives a boil test, or if formaldehyde emissions pass in your market, or how many pours a panel gives. For that you want bonding results to something like EN 314-2, and emissions paperwork of the kind covered in our TSCA Title VI guide.

It doesn't replace legal due diligence either. Under the EU Deforestation Regulation, operators still collect geolocation and legality information themselves; a certificate can support that work but doesn't count as proof of compliance on its own. Our EUDR due diligence guide goes through it. The US Lacey Act works the same way, with the importer still on the hook for legality and the declaration. There's a market-by-market rundown in certification requirements by destination.

Who checks what

Different people on a plywood deal need different bits of this. Here's a rough way to split it.
