Solid Biofuels

SGS facilitates international trade by providing inspection and testing services that verify the availability, quality and loading of wood chips, sawdust, wood pellets and solid bio mass and fuels.

Our global presence means that we can offer these services at source and throughout the supply chain, including all export and import points. And because our standardized reporting considers the defined industry regulations, we make commodity trading and deliveries less contentious and open to dispute.
