Tonka species fact sheet

Rosenfeld Kidson, as timber merchants acknowledge the importance of conserving the world’s greatest renewable resource.

We are pleased to advise that we carry Chain-of-Custody (CoC) certification that enables us to sell timber that carries either FSC certification (SGS-COC-006703) or PEFC certification (SGS-PEFC/COC-0993).

FSC certified timber and PEFC certified timber undergo independent, third-party audited certification procedures at every step of the supply chain. This provides designers, specifiers, architects and consumers absolute assurance that those forest and wood products labelled as FSC certified or PEFC certified originate from legal sources, which are managed to prescribed social, economic and environmental standards.

As a New Zealand timber supplier offering the country’s largest range and quantity of specialist certified timbers we believe that stocking FSC & PEFC certified timber is essential for our continued growth. A major part of our timber range has FSC or PEFC certification and we are continually striving to increase this.
