A major Dutch company was found to having placed illegally sourced teak from Myanmar on the European market, as a recent investigation made by the Environmental Investigation Agency (EIA) revealed.

The Dutch Food and Safety Authority ruled the company in breach of the EU Timber Regulation (EUTR). Also, another company, whose name wasn't released yet, was found guilty too, of violating EUTR requirements.

Boogaerdt Houta was given two months by the Dutch government, as to clear its supply chain of Burmese teak. If after that time the company has still not complied, it will be fined 20,000 euros ($23,000) per cubic meter of illegal timber, Mongabay reported.

Under the EUTR, companies must conduct due diligence to ensure they don’t allow illegally sourced timber into their supply chains and onto the market. The Dutch Food and Safety Authority found Boogaerdt Hout violated these due diligence requirements when bringing Burmese teak into the European market.

Teak (Tectona grandis) is native to South and Southeast Asia, and its wood is prized for use in high-end furniture and boats. While most teak on the market today comes from plantations, some is still illegally sourced from Myanmar. The extraction of this Burmese teak has been denounced by conservationists, who say its trade is helping fuel rampant illegal logging in the country.

According to the EIA, Boogaerdt Hout joins the ranks of at least 17 companies that have been found guilty of violating EUTR requirements by trading in Burmese teak. Boogaerdt Hout did not respond to requests for comment.

The EUTR is part of the EU’s Forest Law Enforcement Governance and Trade (FLEGT) action plan and aims to reduce illegal logging by banning the sale of illicitly sourced timber and timber products in the EU. But while the EUTR is applied EU-wide, member countries are responsible for defining what timber is and isn’t legal. With this ruling, the Netherlands joins Germany, Belgium, Sweden, Denmark and the U.K. in defining teak imported from Myanmar as an illegal wood.

As Mongabay reported, the EIA commended the Myanmar Forest Department for gains made in recent years, including enacting national and regional logging bans, as well as new timber laws.

Yet, the organization claims that there is more that needs to be done to reform the country’s timber industry and reduce illegal logging, specifically calling for greater transparency. This, the NGO says, would go a long way toward independent monitoring and assurance that any teak entering the EU market did not come from a Myanmar rainforest.
