Updates to Sustainable Timber Sourcing WIS

14 December 2016

TRADA has revised its Wood Information Sheet on sustainable timber sourcing to reflect changes to government policy, and to include more information on both FSC and PEFC certification schemes.

Demand for certified timber products has grown dramatically in the past few years and in some cases it is now a legal requirement. Proof that timber comes from a responsibly managed forest is often a key factor in the specification of timber and paper products.

The two main schemes for chain of custody certification in the UK are the Forest Stewardship Council (FSC) and Programme for the Endorsement of Forest Certification (PEFC). Many companies are certified to both schemes but there is currently no mutual recognition between the schemes.

The choice of either certification is largely determined by the country that products are being sourced from and market demand. For example, products such as MDF, OSB and particleboard manufactured in the UK will be typically FSC certified. Most of the timber and panel products imported from Finland will be PEFC certified.

The UK Government has adopted a responsible timber procurement policy in response to concerns about the origins of timber used in government contracts. The policy requires that all timber purchased by central government departments should come from legal and sustainable sources.

Suppliers must have their own chain of custody certification to be able to sell products with FSC or PEFC claims. They cannot rely on the certification of upstream suppliers to pass on claims.

From the specifier’s and end user’s perspective it is generally enough to know whether or not the product is certified, without going into detail about the claim. This only becomes necessary if the product is entering another production/manufacturing business. Even so, it is important to ensure that the minimum claims are being met.
