Ten main groups, named Sections, are defined in order to cover each
principal stage of operation from the initial felling of the tree to manufacture
of the primary product suitable for consumption or further conversion. It also
takes into account the fact that the by-products from one stage of operation
may be used as the raw material for another.

The Sections have the following distinction:
01 Wood in the rough (Roundwood)
It covers all wood raw material taken from wood in the rough,
including chips produced directly in the forest. The basic division
adopted for the classification in this section is on wood fuel and wood
in the rough other than wood fuel.
02 Wood simply worked or processed
This section includes wood charcoal, torrefied wood, roundwood
treated with preservatives, roughly trimmed wood suitable for the
next manufacture or direct use, wood wool, wood flour, wood fuel
simply worked and other wood simply worked such as staves,
shingles and shakes.
03 Wood chips and particles, residues and recoverable wood products
Wood chips and particles covers intermediate products, which may
be manufactured from a number of sources (wood in the rough,
residues or recovered wood products) and have a great variety of
uses e.g. for pulp, particle board, etc.
Wood residues consist of wood which has passed through some form
of processing but which also constitutes the raw material of a further
process e.g. for pulp, particle board, etc.
Recoverable wood products are incorporated into classification as
potential source of the raw material for production of pulp, particle
boards, fibreboards or for energy purposes.
04 Wood pellets and other agglomerates
This section includes wood pellets and other agglomerates such as
wood briquettes which are mainly produced from co-products of the
mechanical wood processing industry, furnituremaking industry or
other wood transformation activities.
05 Sawnwood
This section covers the products of the simple processes of sawing
lengthways, with the associated processes of hewing or profile
chipping. It encompasses sleepers, sawnwood rough or sawnwood
planed
06 Veneer sheets
Veneer sheets are thin sheets of wood of uniform thickness not
exceeding 6 mm obtained by sawing, slicing or peeling. Veneer
