Summary

 As part of its new remit as the Construction Products Regulator, the Office for Product Safety and Standards (OPSS) has been contacting companies across the timber supply chain – including some Timber Development UK (TDUK) members – to check compliance around fire retardant (FR) treated wood-based products. 

These products are inherently safety-critical and ensuring their traceability and performance claims meet the legal requirements of the Construction Products Regulation (CPR) is now a top priority for regulators. A key issue that OPSS is focusing on relates to the Declaration of Performance (DoP) created to support fire retardant treated products when they are placed on the market.

As a company, if you are sending Plywood or cladding to a treatment plant for FR treatment then, legally, you are making an additional claim about its performance and therefore must take on the responsibilities as the manufacturer of that product – this includes producing a new DoP.
