Tech titan Jeff Bezos's $500m (£366m) superyacht, Koru, delivered in 2023, uses teak in its interior and for its decking.
The dense and heavy tropical hardwood is prized for its remarkable properties such as rot and salt resistance, as well as its beauty and as a symbol of status and prestige.
The highest quality teak comes from old-growth trees, which are harvested from natural forests almost exclusively in Myanmar.
But sold by the country's military-linked sector, with little regard for sustainability, the timber is illegal to import into the UK, EU and US.
Trade sanctions were imposed on the sector in 2021 following the coup there, though imports were already heavily restricted under longstanding laws.
