The UK Timber Regulation (UKTR) requires businesses that first place timber or timber-based products — such as MDF-backed panels — on the UK market to carry out due diligence confirming the timber was legally harvested, and to keep records of who they bought from and sold to. Which obligations apply to you depends on whether you're an 'operator' (the business first placing the product on the market) or a 'trader' (buying and reselling an already-placed product within the UK) — traders carry lighter record-keeping duties than operators.
- UKTR applies to timber and timber-derived products, including board products like MDF, placed on the UK market.
- An 'operator' first places the product on the UK market and must carry out due diligence on legality of harvest. A 'trader' buys and resells an already-placed product and has lighter record-keeping duties.
- Due diligence means identifying the product and its origin, assessing illegal-harvest risk, and mitigating that risk where it's more than negligible.
- Traders mainly need to keep records of their suppliers and customers, not carry out the full risk assessment an operator does.
What the UK Timber Regulation covers
The UK Timber Regulation (UKTR) prohibits placing illegally harvested timber, or products made from it, on the UK market. It applies broadly across timber and timber-derived products, which includes engineered board materials such as MDF used as a core or backer in panel products — not just solid sawn timber.
The regulation puts the compliance burden on whoever is responsible for a product's first entry to the UK market, with lighter obligations further down the supply chain — which is why the operator/trader distinction matters.
Operator vs trader
An operator is the business that first places a timber product on the UK market — typically an importer or a manufacturer bringing a product in from outside the UK. An operator must exercise due diligence: identifying the product and its species, establishing the country (and, where relevant, the region and concession) of harvest, assessing the risk that the timber was illegally harvested, and applying risk-mitigation measures if that risk is more than negligible.
A trader is a business further down the chain — buying an already-placed product and reselling it within the UK. Traders have lighter duties, mainly keeping records of who they bought a product from and who they sold it to, for a set retention period, so the supply chain can be traced if needed.
What a due-diligence pack typically contains
For an operator, a due-diligence system under UKTR generally gathers: a description of the product and the timber species involved; the country of harvest and, where applicable, the sub-national region and the concession the timber came from; documentation from the supplier confirming legal harvest; a risk assessment weighing that information; and any risk-mitigation steps taken where risk isn't judged negligible.
For a trader, the requirement is simpler: keep clear records of suppliers and customers for the retention period set by the regulation, so the chain of custody can be reconstructed if a regulator asks.
What to ask a supplier
If you're buying a timber-based product to resell, ask your supplier directly whether they act as the operator for that product, and what due-diligence documentation they hold or are collecting — species, country of harvest, supplier declarations. A supplier who states plainly what they currently hold, and what's still pending, is easier to do due diligence on yourself than one who is vague.

Frequently asked questions
Does UK Timber Regulation apply to MDF, or only solid wood?
It applies to timber-derived products generally, which includes engineered board materials like MDF, not solid sawn timber alone. If a product has a timber-derived core or component, UKTR considerations apply to whoever first places it on the UK market.
Am I an operator or a trader if I buy panels and resell them in the UK?
If you're buying an already-imported product from a UK-based supplier and reselling it within the UK without importing it yourself, you're generally a trader, with lighter record-keeping duties than the operator who first brought it into the country.
What records does a trader need to keep?
Mainly who you bought the product from and who you sold it to, kept for the retention period the regulation sets, so the supply chain can be traced. This is materially lighter than the full due-diligence and risk-assessment obligation that falls on an operator.
