The 'Mahogany' Order and a Friday Deadline
A class of 24 is making jewellery boxes about 200 × 120 × 60 mm from 25 mm boards. The supplier's quote lists four options: 'Genuine mahogany, 25 mm, €48 per 2 m board, FSC Mix 70%'; 'European oak, 25 mm, €62 per 2 m board, FSC 100%'; 'White lauan, 25 mm, €30 per 2 m board, certification not stated'; and 18 mm MDF at €22 per 2440 × 1220 mm sheet, marked 'E1'. The school's purchasing policy says timber must be 'legal and, where possible, certified sustainable'. The order has to go in on Friday and the budget is €1,200. A parent has emailed to say her child does not want to work with 'rainforest wood'. The technician points out that MDF dust is already a problem in the room and that the finish scheduled is one coat of sanding sealer and a wax.
1. What do the descriptions 'genuine mahogany' and 'FSC Mix 70%' actually tell you? What would you insist on from the supplier before signing the order?
Read the worked answer
'Genuine mahogany' tells you almost nothing. It is a trade name, not a species. It has been used for American mahoganies in the genus Swietenia, which are listed on CITES Appendix II so international trade requires permits, and also loosely for African mahoganies such as Khaya and sapele, several of which are also CITES-listed, and sometimes for unrelated species. 'Lauan' and 'meranti' are a similar problem: a group of South-East Asian species grouped behind one trade name. Without the botanical name you cannot check legal status, CITES listing, density, movement or working properties. The lathe and the hand tools will tell you quickly if you have been sold something harder or more brittle than you planned for.
'FSC Mix 70%' is a real claim, but a mixed one. It means at least 70% of the fibre is FSC-certified or recycled, with the balance controlled wood that meets the scheme's minimum risk criteria but is not certified forest. It is much better than nothing and is verifiable, but it is not the same as FSC 100%.
What to insist on in writing. Full botanical name and accepted trade name; country and region of harvest; the certification scheme, certificate number and chain-of-custody code for this specific supplier, which you then look up on the scheme's public database; the exact label claim (100%, Mix X%, Recycled); and the supplier's due-diligence records under the EU Timber Regulation, which is being replaced by the EU Deforestation Regulation, so ask what they hold now. Ask whether they will substitute a verifiable species at a similar price, and get a sample board to check colour and workability before the whole order.
2. Compare the four options on function, health and environmental grounds, and make a defensible choice for this class.

First, size the order - the cost argument may collapse. Each box needs roughly 0.09 m² of 25 mm stock, so 24 boxes is about 2.1 m², say 2.7 m² allowing 30% waste. A 2 m board at 150 mm wide is about 0.3 m², so around nine boards. At €62 that is roughly €560 for FSC 100% oak, comfortably inside €1,200. The cheapest option is not buying you much.
Mahogany. Lovely to work, stable, takes a finish well. But the species is unknown, the certification is mixed, and the permit question may not be answerable by Friday. Purchasing an unverifiable CITES-listed group to save money, against a parent's objection, is a poor trade for a school.
European oak, FSC 100%. Full certification, a European species with short transport, hard and durable. It is harder on hand tools and dulls edges faster; tannins react with steel fixings and can stain the timber if it is wetted; it is heavy for a small box but fine at this size. It is the most defensible choice: you can verify the claim and explain it.
White lauan. Cheapest and no stated certification. Unverifiable species and origin, and the group is associated with conversion forest in South-East Asia. Only acceptable if the supplier produces a chain-of-custody code and a botanical name, which they probably cannot by Friday.
MDF, E1. No forest-conversion risk if the fibre is certified or recycled, dimensionally stable, no movement and no joint problems, cheap and consistent. Against it: a urea-formaldehyde binder, fine dust that is a genuine respiratory hazard in a room with existing extraction problems, and poor screw-holding, so hinges need a solid lipping or insert. E1 is a low-emission class, not an emission-free one, and the cut edges need sealing.
Choice. FSC 100% oak for the visible parts, with offcuts and reclaimed stock for internal dividers. If the budget or tooling makes oak impractical, certified MDF for the carcase with an oak lipping is the second choice - but only after the extraction is fixed. Reject the unverifiable option and say why in writing.
3. The budget is tight and the head of department wants the maximum environmental benefit per euro. How would you spend the €1,200 and what would you put in place to make the choice stand up to scrutiny?

Spend on verification and on waste, not on the cheapest board. Buy one certified species in bulk, sized to the actual cut list rather than to a round number of boards, and keep an offcut store so small parts are cut from waste. Order with the chain-of-custody code and species name printed on the invoice and the delivery docket, so the claim is on record if it is questioned. If the supplier can only offer Mix 70%, ask what the remaining 30% is and whether they can source 100% next term.
Put the saving where it does most good. The gap between the cheapest and the certified option is a few hundred euro. Spending part of that on dust extraction at the machines, a proper sanding station and a water-based finish does more for the health of 24 students than any board choice, and it is measurable. A water-based finish also removes the solvent vapour problem the technician flagged with the current schedule.
Design out waste and movement. A jewellery box in certified oak with a stable manufactured base and a floating panel lid uses less solid timber than an all-solid design, and it will not come back split. Thinner stock for the lid, lippings instead of solid sides, and standard sizes that nest on the board all reduce the volume ordered.
Make it auditable. Keep a one-page record for the project: species, certificate code, supplier, volume, source of any reclaimed material, finish used and disposal route for offcuts. Show it to the class - the exercise is as much about being able to justify a choice as about making it. Then answer the parent with the certificate number and the species name, not with an assurance.
