Standard development

Standard development Process


Zanzibar Bureau of Standards (ZBS) was established under the Standards Act No.1 of 2011 with the aim of formulating national standards, promote and facilitate their implementation with a view to improving industrial competitiveness and efficiency to enhance trade, and protect the consumer and the environment. The formulation of Zanzibar Standards is done through a consultative process and general consensus principle through technical and Divisional committees. These committees are made up of experts from different stakeholders to ensure balanced representation.


During the preparation of Zanzibar Standards, assistance is mainly derived from other standards from national, regional and/ or international standardization bodies and adopted to suite our cultural, climatic, industrial or economic environment
