Groupe Roullier has developed expertise that is unique worldwide in the three applications of magnesia: agricultural, industrial and refractory. The synergies resulting from this structure have strengthened our business model. TIMAB Magnesium is the Groupe Roullier business unit that specialises in agricultural applications.

Our production sites

With two integrated production sites – Magnesitas Navarras and Magnesium do Brazil, producing more than 120,000 tonnes of agricultural magnesia per year, we can ensure full traceability for our products. Thanks to our network of partners and strategic alliances, the TIMAB Magnesium sales network is always available to respond to our customers’ needs.

Priority is given to quality and security of supply

Alliances expand the distribution network whilst keeping focus on product quality, full traceability and supply chain reliability. In June 2012, TIMAB Magnesium added its own sourcing bureau in China to its business, in the mineral resources heartland of Liaoning. The aims were to expand the “International Plant Nutrition” range, to meet the sourcing needs of other Groupe Roullier magnesia subsidiaries (with industrial applications, such as Van Mannekus, Magnesitas Navarras…)  and service our Asian customers, seeking high-potential products (in terms of nutrition and zootechnics).
