It establishes three different Appendices (commonly referred to as 'lists') which give the names of the species of all manner of things - birds, beasts and plants - that are in some way threatened with population reduction or even extinction; and which may be restricted in their trade around the world. Species on List 1 are illegal to trade in; List 2 may be traded with appropriate licences; and List 3 is “desirable” for upgrading to List 2, if all countries agree to it.

Proof (by means of a documented system) that all reasonable steps have been taken by the 'first placer' (qv) of any wood-derived products onto the market within the EU, to ensure that all such products have been legally obtained from their source(s).
EPD (Environmental Product Declaration)
An EPD presents LCA information using a well-defined set of product category rules, to promote comparison between products, on the basis of functional units.
EU timber regulation that requires companies that place wood or wood products on the EU market to assess the risk of illegalwood sourcingand to maintain full records of their actions in mitigating such risk.
A North American term, meaning that the annual growth rings run more or lessperpendicular to the edge / narrow face in rectangular timber sections.
FLEGT (Forest Law Enforcement Governance and Trade)
An administrative arrangement set up between the EU and some other timber - exporting country's Government to prove - by means of documentation and licences - that any wood goods exported from that country have been obtained from trees that were legally felled. This may or may not include forest 'sustainability,' which it does, in the case of Indonesia.

ITTO (International Timber Organisation)
A loose association of interested parties - governments, timber traders and others - who try to ensure that Tropical Forests are used wisely but also commercially.
LCA (Life Cycle Analysis)
LCA is a methodology for evaluating the environmental impacts of any product or process. LCA can be conducted from "cradle to gate," or from cradle to grave, and it reports the environmental burdens (e.g. global warming potential, eutrophication, ecotoxicity) of manufacture (and also use).
Medium density fibreboard - a manufactured wood-based panel made from wood fibres, with a small percentage of resin.
MMC (modern methods of construction)
Several building systems, including timber framed systems, are classed as MMCs, based on the use of off-site factory manufacture for part or all of the assembly process. Wall and roof panels, floor cassettes, pods or volumetric units can then be shipped to site for rapid erection.
MTCC/MTCS (Malaysian Timber Certification Council/Scheme)
This provides validated Chain of Custody certification for timbers from Certified Malaysian forests (although it is verified in the UK by PEFC).
MYTLAS (Malaysian Timber Legality Assurance System)

The Government’s Office of Specification and Standards – this replaced the NMO (National Measurement Office) as the arbiter of acceptable timber Legality and Chain of Custody Schemes.
P A R (S4S)
Timber that has been "planed all round." Also means S4S - "surfaced 4 sides," or DAR "dressed all round." As distinct from rough sawn, which is timber coming direct from the saw line with no further processing.

All boards sawn by parallel cuts from the log.
Packaged to length. All the pieces in a pack are the same length. (As distinct from truck bundled, which is random lengths per package.)

RPP (Responsible Purchasing Policy)
Members of the TTF (qv) are required to complete an annual return under the RPP to show that they are ensuring legality in their timber purchases and that they have the necessary Due Dilligence (qv) mechanisms in place.
