APA Guidelines

Wood-Based Products in UK & EU Construction

The Guidelines section is where we provide up-to-date information on the structural standards and regulations in the UK and EU that engineered wood products must comply with. There are also different conformity assessment rules depending on whether panels are entering EU countries or Great Britain and Northern Ireland.

Recent changes mean that importers face greater responsibility for checking the source of any products, ensuring they have written evidence that the timber is not illegally harvested – and the value of having chain of custody certification (CoC) from a recognised independent body such as FSC or PEFC.  

How to identify the standards you need

We’ve created an interactive database, Find Your Standard, for plywood, OSB and LVL. This brings together all the relevant information you need to identify which standards apply to specific products and applications.

As UK and EU standards currently don’t diverge in their principles, and to make the database easy to use, we have created a combined title for each standard – keeping the main part of the title the same, simply adding (BS) to denote it is the same for ‘British Standards’ as it is for the EU.

You can find out when standards are reviewed, here.

For I-joists, it is a little different as there is still no EU standard or UK standard. Instead, you need a European Assessment Document (EAD). Until there is a UK version, the same EAD applies to both geographies. More.
