award for enterprise

The Queen’s Award for Enterprise x

PROINSO won the 2018 Queen’s Award for Enterprise in International Trade, in recognition of its outstanding international performance. The Queen’s Award is the UK’s most prestigious award for business success, and recipients are chosen on the advice of the Prime Minister, who is assisted by an Advisory Committee that includes representatives of Government, industry and commerce, and the trade unions.

The Royal Grant of Appointment can be attributed to PROINSO’s outstanding export growth of 115% in three years to over 100 countries. This is coupled with PROINSO’s assurance of responsible conduct in managing social and environmental impact, selecting and controlling suppliers, managing the production process, human resources, and customer service.
