Chain of custody – seamless traceability of wood products
Definition: Chain of Custody (CoC) is a system for the seamless traceability of wood products. It documents the path of wood from the forest through all processing and trading steps to the end product in order to ensure its origin and compliance with certification standards such as FSC®.
Chain of custody describes the seamless traceability of wood products along the entire value chain – from the forest to processing and trade to the end product. This product chain is the basis for certification claims (e.g. FSC®) and creates verifiability regarding origin, processing and labeling.
Chain of custody: The unbroken chain of traceability in the timber trade
What exactly does chain of custody mean?
Chain of custody refers to the system used to verify and document the origin of wood species and wood-based materials at all stages. The aim is to ensure that materials declared as certified actually originate from permitted or certified sources. This includes rules on labeling, separate storage and documentation and internal controls in production and trading companies. Chain of custody is therefore the basis for trustworthy product information for customers and authorities.
An overview of the chain of custody
Why is traceability important for certificates?
Binding requirements apply to the use of FSC labels: Only if all relevant stages of the product chain meet the requirements may a product be labeled as FSC-certified sold or labeled with the FSC trademark. The central standard for this is FSC-STD-40-004 (Chain of Custody Standard). Companies must provide evidence of internal processes, accounting and separation systems; independent audits check compliance. In this way, the system protects against false claims of origin and strengthens the credibility of sustainable timber products.
The FSC certificate as proof of chain-of-custody conformity
How does chain of custody work in practice?
In practice, CoC conformity for manufacturers and dealers means: documentation of incoming materials, clear processes for mixing or changing material compositions, as well as audit readiness. For planners and consumers, this means that anyone selecting decking products, teak boards or other items for outdoor wood use can verify whether the wood used comes from a responsible source if the supply chain is CoC-certified. Industry services and associations provide information on how companies can apply for certification and what practical consequences the chain of custody rules have for purchasing, storage and labeling.

Frequently asked questions about chain of custody
Chain of Custody, or chain of custody, is a certification system that guarantees the complete traceability of wood and forest products from their origin in the forest to the end consumer. It ensures that products labeled as certified actually come from sustainably managed or controlled sources.
CoC is crucial to ensure the credibility of sustainability certificates such as the FSC®. It prevents non-certified wood from being sold under the guise of certified products and gives consumers and retailers certainty about the legal and responsible origin of the material.
FSC-STD-40-004 is the central chain-of-custody standard of the FSC. It defines the requirements for companies along the supply chain to ensure that certified material is stored separately, processed correctly and clearly labeled. Products may only bear the FSC label if they comply with this standard.
Consumers can recognize products with proof of chain of custody by the logo of the respective certification system, e.g. the FSC logo. This guarantees that all companies along the product chain that have processed the material are themselves certified according to the chain of custody standards and are subject to regular inspections.
