Data are collected on inputs and on production.
The data collected on inputs covers the type of input (roundwood, sawmill products, imports) and the type of wood (softwood, hardwood).
Production data covers all types of woodbased panels made in the UK, which currently comprises particleboard (including oriented strand board) and fibreboard (medium density fibreboard). Production of hardboard (another type of fibreboard) ended in 1999 and production of plywood ended in 2000.
The data on woodbased panels are collected by the Wood Panel Industries Federation (WPIF), which represents all UK wood panel manufacturers. Figures on wood consumption are collected annually. Production data (excluding waste and rejects) are derived from quarterly returns. Response rates in recent years have been 100%.
The statistics on woodbased panels are not normally revised after publication. On occasion, a provisional figure or estimate may be published, and replaced by the actual figure in a subsequent publication.
Statistics reported for each year are available at a UK level only.
