This document specifies requirements for a chain of custody (CoC) of wood and wood-based products, cork and lignified materials other than wood, such as bamboo, and their products. NOTE – The term "material" will henceforth be used throughout this document to denote "raw materials and products from wood, cork and lignified materials other than wood, such as bamboo", as defined in 3.8. This document is applicable to material that originates from different categories of input material and can be derived from mechanical, chemical, biological and/or thermal processing or a combination thereof. A chain of custody relies on a control system to track and handle material throughout the entire supply chain or parts of the supply chain, including transportation, receipt, production, sale, resale and output declaration. This document is intended to enable tracking of material from different categories of source to finished products. Furthermore, this document also specifies minimum requirements for input material. This document is not applicable to forest management.
