FSC certification: what the label really guarantees

The FSC certification (Forest Stewardship Council) attests that a wood comes from a responsibly managed forest and that it remains traceable all the way to the finished product. It is now a benchmark required in public procurement, timber-construction tenders and clients’ specifications. A supplier that cannot justify the origin of its wood is excluded from these markets.

But the FSC logo does not say everything. Behind it are two different certificates and three product labels, which do not provide the same level of assurance. A merchant buying from a certified supplier cannot necessarily resell the product as certified, and a Mixed label does not mean the same as a 100% label. Certification is also not enough to make you compliant with European regulations on the origin of wood, which impose their own due-diligence obligations.

FSC certification at a glance

• FSC (Forest Stewardship Council) is an international non-governmental organization that defines the requirements for responsible forest management. Independent, accredited certification bodies issue certificates, after an audit, to those who apply. The approach remains voluntary.

• Two certificates coexist depending on your position in the supply chain: forest management for those who produce the wood, and chain of custody for those who process or sell it. Each is valid for 5 years, with an annual surveillance audit.

• Three product labels exist. FSC 100% refers to wood entirely sourced from certified forests, FSC Recycled to a product made from recovered material, and FSC Mixed to a mix that includes non-certified wood, which must then meet minimum requirements called Controlled Wood. A product displayed as “FSC” without further detail therefore does not say what share of its wood really comes from a certified forest.

• Certification does not exempt you from legal obligations. The EU Deforestation Regulation (EUDR) requires the company that places wood on the European market to verify the origin of its material itself and keep evidence. An FSC certificate is one piece of evidence among others; it does not replace this verification.

• In France, the FSC-certified area remains marginal. In March 2026, it represented 135,809 hectares in mainland France, i.e., less than 1% of the French forest, versus about 5.8 million hectares for the PEFC label (June 2026), the other major sustainable forest management certification. This gap limits the supply of FSC-certified French timber.

What is FSC certification?

FSC certification (Forest Stewardship Council) is an international label that guarantees that a wood or paper product comes from responsibly managed forests. It covers environmental protection, respect for workers and Indigenous peoples, as well as traceability of wood from the forest to the finished product.

It targets two audiences. Forest owners and managers certify their forestry practices. Companies that buy, process or resell wood certify their material flows. On finished products, three distinct labels indicate what the wood actually contains: FSC 100%, FSC Mixed and FSC Recycled.

Who is the Forest Stewardship Council?

The Forest Stewardship Council is an international non-governmental organization. Its founding assembly was held in Toronto in 1993, one year after the Rio Earth Summit, at the initiative of companies, environmental NGOs and social-rights representatives. Its secretariat has been based in Bonn since 2003.

Its role is to define the requirements that a sustainably managed forest must meet, and then evolve them with its members. These are distributed across three chambers—economic, environmental and social—each with equal voting weight.

In France, the FSC France association adapts these international requirements into a national standard suited to French forests.

Who issues FSC certificates?

FSC itself does not issue any certificates. It defines the requirements, and external certification bodies carry out audits and issue certificates, which prevents FSC from being judge and jury.

These bodies do not self-declare as certifiers. They must be accredited by Assurance Services International (ASI), the independent body responsible for verifying that they correctly apply FSC rules. ASI reviews them every year and can suspend them in case of non-compliance.

About ten bodies manage FSC certificates in France, with accreditations that differ depending on the targeted certificate.

What is the FSC standard based on?

The international standard is based on ten principles, detailed by 70 criteria, themselves broken down into country-specific indicators:

1. Compliance with laws

2. Workers’ rights and working conditions

3. Indigenous peoples’ rights

4. Community relations

5. Benefits generated by the forest

6. Environmental values and impacts

7. Management planning

8. Monitoring and assessment

9. High Conservation Values

10. Implementation of management activities

In mainland France, principle 3 is not applicable, as there are no Indigenous peoples in the sense of the United Nations. The other nine are translated into verifiable field indicators, developed by a national working group and then submitted for public consultation. The standard in force for mainland France came into application on September 1, 2025, and it is revised every five years.

Who is concerned by FSC certification ?

FSC certification concerns wood professionals depending on their position in the supply chain. Forest owners and managers fall under a first certificate, forest management. Companies that buy, process or resell wood fall under a second certificate, chain of custody. The same organization that manages its forest and processes its wood can hold both.

Forest management certification

Forest management certification is intended for owners, managers, operators and forestry cooperatives. The auditor visits the plots and checks that practices comply with the national standard indicators described above.

The audit covers the management plan, biodiversity monitoring, harvesting methods, working conditions, and the consideration of local issues and forest users.

Chain of custody

Chain of custody is intended for companies that handle, process, manufacture, print or sell forest-based products. Without it, a company cannot mention FSC status on its sales documents, label its products, or communicate about this certification in a catalogue or on its website, even if it sources exclusively from certified suppliers.

The certificate is issued for 5 years and renewable by an accredited certification body. It ensures product traceability throughout the value chain.

Can you get certified together?

A group certificate is not a third certificate. It is an option that exists for each of the two certifications and allows several entities to be grouped under a single certificate, held by a group manager. The latter is the certification body’s point of contact, defines the group’s rules, carries out internal audits and archives evidence of compliance. It does not combine the two certifications; it pools one or the other across several entities.

In forestry, the scheme is intended for private and public owners who group together. It reduces the cost and workload for each member, and neither the number of members nor the area is capped.

For chain of custody, access is reserved for small entities. Companies must be located in the same country and have a maximum of 15 full-time equivalent employees, or a maximum of 25 full-time equivalents with cumulative annual turnover under one million US dollars. The annual audit then covers a sample of the group’s companies, not all of them.

And for a construction site? Project certification

Project certification is a special form of chain of custody, applied not to a company but to a work. It applies to a construction, a renovation, a civil engineering work or even a unique object.

It can be complete, when it covers all the wood incorporated, or partial, when it only covers certain lots such as cladding or joinery. In both cases, it allows the project owner to communicate about the share of certified wood in their building, which simple sourcing of certified products is not sufficient to authorize.

Which wood products can carry the FSC label?

Any product originating from a certified forest can carry the FSC label, provided that every link in the supply chain is itself certified under chain of custody. A single non-certified intermediary is enough to break the traceability link and prohibit labeling.

For construction and fit-out, this includes structural timber, cladding, decking boards, parquet flooring, wall paneling, wood-based panels, roof frames and structural systems and joinery, as well as paper and cardboard.

What does each FSC label guarantee ?

A certified finished product carries one of the three FSC labels. They differ in the share of certified wood they guarantee.

• FSC 100%: all the wood or fibre comes from FSC-certified forests.

• FSC Mixed: at least 70% FSC-certified and/or recycled wood or fibre. The remaining 30% maximum is not certified, but must be Controlled Wood, wood whose origin has been verified.

• FSC Recycled: recycled wood or fibres. For wood products, the material must come from products already used by a consumer.

Simply writing “FSC” in a CCTP (special technical specifications) or a technical note therefore says nothing about the share of certified wood. You must specify which of the three labels.

What is Controlled Wood?

Controlled Wood is not a commercial label. It is the minimum requirement imposed on the non-certified share of a Mixed product. This wood is not FSC-certified, but it cannot come from just anywhere.

Five categories of sources are excluded:

• illegally harvested wood,

• wood harvested in violation of human rights and traditional rights,

• wood from forests where high conservation values are threatened,

• wood from forests containing genetically modified trees,

• wood from forests converted to plantations or to non-forest use.

The company must know where its wood comes from and verify that it does not fall into any of these categories. To help, FSC publishes country risk assessments. The one for mainland France concludes that the risk is low: wood whose French origin is demonstrated can therefore be accepted as Controlled Wood, after verification during the audit.

When the country of origin presents a risk, or when no analysis exists, the company must investigate its suppliers further and document its checks. Its certification body reviews this work.

A product under the FSC label therefore never mixes certified wood with wood of unknown origin.

Does an FSC product always contain certified wood?

Not necessarily. Three methods allow a company to determine what it can sell under the FSC label, and they do not yield the same result in the delivered product.

1. Segregation. Certified materials are never mixed with others. The company reserves either a production line or a dedicated time slot for them. Output carries the label of the input. This is the most faithful method, and the only one allowed for merchants.

2. Percentage. The company mixes certified wood and Controlled Wood, then calculates the certified proportion over a maximum of twelve months. All concerned products are sold with this percentage. Each item reflects the average of production.

3. Credit. The company buys certified wood and earns an equivalent credit. It can then sell the same quantity of products under the FSC label, without that wood necessarily being in them. If it buys enough to make 100 certified boards, it sells 100 boards under the FSC label, even if the certified wood went elsewhere. The guarantee covers the volumes purchased, not the specific board you receive.

WoodPartners tip

Before repeating an FSC claim in a contractual document, ask for the exact label. For a Mixed product, also ask for the actually certified share and the method used. This information appears on the supplier’s sales documents.

How to obtain FSC certification?

You must go through an accredited certification body, which audits your company or your forest and then issues the certificate. FSC France does not certify itself, but can answer your questions during the process.

For chain of custody, FSC France describes four steps:

1. Become familiar with the requirements. Identify those you already meet, those that require work, and the internal costs this represents. FSC publishes an implementation guide for the standard to help you.

2. Choose your certification body. About ten bodies manage certificates in France. You provide them with some information about your activity; they send back an estimate of the audit duration and cost, then you sign with the one you select.

3. Undergo the audit. An auditor visits and checks that you meet the requirements of FSC standards.

4. Receive your certificate. If the audit is successful, the body awards you the certification. Your company then appears in the FSC Search database, which lists all certificate holders.

If the audit reveals gaps, you implement corrective actions and a new audit is possible.

How long does it take?

Certification bodies generally indicate four to eight weeks for chain of custody, depending on the size and complexity of the company. Upstream preparation represents most of this timeframe.

Forest certification takes more time, due to stakeholder consultation and the field audit. A pre-audit is also mandatory beyond 10,000 hectares or in the presence of high conservation values, and remains optional below that threshold.

How to choose your certification body ?

Accredited bodies are not the same depending on the targeted certificate, and this is the first filter to apply.

For forest management, four bodies have a French-speaking contact or manage certificates in France: Ecocert, Preferred by Nature, SGS and Soil Association. Four others are accredited but do not manage forest certificates in France.

For chain of custody, the choice is broader: eleven bodies have a French-speaking contact. In addition to the four above, there are Bureau Veritas, Control Union, the FCBA technology institute, SAI Global, SQS, TdcV NORD France and WOOD.BE.

Once this filter is applied, FSC requirements are identical from one body to another, since they derive from the same standards. The choice is therefore made on practical criteria: audit cost, knowledge of your sector and the announced lead times. Request several quotes before committing, as the process explicitly provides for this.

FSC France keeps the complete list up to date, with contact details for each person.

How long is an FSC certificate valid?

An FSC certificate is valid for 5 years. During this period, the certification body that issued it carries out a surveillance audit every year to check that the company or forest manager continues to meet the requirements. At the end of five years, a full reassessment is required to renew the certificate.

Why verify a supplier’s certificate?

Because responsibility for the claim flows through to you. If you state certified wood in a quote, a CCTP or a product sheet, it is up to you to be able to prove it, and a verbal commitment from the supplier is not enough.

Three situations make this verification necessary.

• A market requires it. Many public tenders and specifications impose a percentage of certified wood. Without proof, the lot may be rejected.

• Regulation commits you. The EUDR requires the company that places wood on the European market to verify the origin of its material itself. Your supplier’s certificate is part of that file—provided it is valid.

• The system itself is monitored. FSC has implemented an anti-fraud plan, with verification of transactions declared by certificate holders. Discrepancies exist, and they are actively sought.

How to verify a supplier’s FSC certification?

You can verify a supplier’s FSC certification by asking for their certificate number and entering it in FSC Search, FSC International’s public database. This database indicates whether the certificate exists, whether it is still valid, which body issued it and which products it covers.

Three points deserve your attention.

1. Validity date. Check that the certificate is current, because a suspended or expired certificate is sometimes still displayed on commercial materials.

2. Scope. Check that the range you are buying is covered, because a certificate applies to specific product groups and not to an entire catalogue. A supplier may be certified for one range and not for the one that interests you.

3. Type of document. Make sure it is indeed a certificate, because a promotional licence is not one. It authorizes a non-certified company to use the FSC trademark in its communication, but not to pass on FSC status on its sales documents.

WoodPartners tip

An FSC logo in an email signature or on a brochure has no value in itself. It may fall under a simple promotional licence, which is legitimate but does not grant the same rights. Only the certificate number, verified in FSC Search, settles the question.

FSC or PEFC: what differences for a wood professional?

FSC is not the only sustainable forest management label. The PEFC (Programme for the Endorsement of Forest Certification) is the other major system present in France. Both pursue the same goal, but they are two distinct certifications, with no equivalence: PEFC wood cannot be sold as FSC.

FSC, created in 1993, applies a single international standard adapted by country. PEFC, created in Paris in 1999, works by recognizing national schemes developed locally—an approach that better fits small private European forest holdings.

Substantively, both systems rely on assessments carried out by independent third parties. FSC is often presented as the more demanding of the two on social criteria and high conservation values. This view circulates in the sector; it is not based on a measured comparison.

This difference in model explains the difference in uptake. In June 2026, PEFC covered 5,772,680 hectares in mainland France, i.e., 35.3% of the forest area², versus 135,809 hectares for FSC in March 2026, i.e., less than 1%¹. Concretely, sourcing French FSC wood remains limited in volume, whereas French PEFC wood is found in most timber-trade channels.

Is an FSC certificate sufficient in light of the EU Deforestation Regulation (EUDR)?

No. FSC certification helps with EUDR compliance, but it does not make you compliant on its own. The burden of proof remains with the company.

Regulation (EU) 2023/1115 prohibits selling in Europe wood from a forest destroyed or degraded after December 31, 2020.

Whoever first places the wood on the market—forest operator in France or importer—must trace its origin and file a declaration in the European TRACES system. They receive a reference number. Subsequent companies are also concerned, but only have to keep this number and pass it on.

FSC certification facilitates this work: it already documents the origin and legality of the wood. FSC even offers a module dedicated to the EUDR. But a standard chain-of-custody certificate does not cover everything, notably plot geolocation.

An FSC-certified supplier therefore does not relieve you of asking them for their declaration number. It is this number, not the certificate, that proves EUDR compliance.
