Cambodian companies producing engineered hardwood flooring for the U.S. market are getting their timber from a company described as a cartel that’s been repeatedly accused of illegally logging inside protected areas. Angkor Plywood is the sole supplier of plywood to flooring manufacturers based in the Sihanoukville Special Economic Zone, and claims the wood comes from its acacia and eucalyptus plantations. However, watchdog groups, industry insiders and independent media, including Mongabay, have long documented evidence of Angkor Plywood and its supplier, Think Biotech, felling tropical hardwoods inside Prey Lang Wildlife Sanctuary. AHF Products, which claims to be the biggest U.S. wood flooring manufacturer, runs a factory in the Sihanoukville SEZ, but denies any protected wood entering its supply chain — a claim industry veterans question, given Angkor Plywood’s notoriety.
