Uganda National Bureau of Standards (UNBS) is a parastatal under the Ministry of Trade, Industry and 
Cooperatives establishe d under Cap 327, of the Laws of Uganda, as amended.  UNBS is mandated to co -
ordinate the elaboration of standards and is  
(a) a member of International Organisati on for Standardisation (ISO);   
(b) a contact point for the WHO/FAO Codex Alimentarius Commission on Fo od Standards;  and  
(c) the National Enquiry Point on TBT Agreement of the World Trade Organisation (WTO).  
The work of preparing Uganda Standards is carried out through Technical Committees. A Technical 
Committee is established to deliberate on standards in a g iven field or area and consists of representatives of 
consumers, traders, academicians, manufacturers, government and other stakeholders.  
Draft Uganda Standards adopted by the Technical Committee are widely circulated to stakeholders and the 
general public  for comments. The committee reviews the comments before recommending the draft standards 
for approval and declaration as Uganda Standards by the National Standards Council.  
This Draft Uganda Standard, DUS DEAS 1041 :2021 , Dried cassava l eaves — Specification , is identical with 
and is being  reproduce d from a Draft  East African  Standard, DEAS 1041 :2021 , Dried cassava l eaves — 
Specification , and is proposed for adoption  as a Uganda Standard.  
The committee responsible for this document is Technical Committee UNBS/TC 2, Food and a griculture . 
Wherever the words, “East African  Standard " appear, they should be replaced b y "Uganda Standard."

 Foreword  
Development of the East African Standards has been necessitated by the need for harmonizing requirements 
governing quality of products and services in East Africa. It is envisaged that through harmonized 
standardization, trade barriers which are encountered when goods and services are exchanged within  the 
Community will be removed.  
 
In order to meet the above objectives, the EAC Partner States have enacted an East African Standardization, 
Quality Assurance, Metrology and Test Act, 2006 (EAC SQMT Act, 2006) to make provisions for ensuring 
standardizatio n, quality assurance, metrology and testing of products produced or originating in a third country 
and traded in the Community in order to facilitate industrial development and trade as well as helping to 
protect the health and safety of society and the en vironment in the Community.  
 
East African Standards are formulated in accordance with the procedures established by the East African 
Standards Committee. The East African Standards Committee is established under the provisions of Article 4 
of the EAC SQMT Act, 2006. The Committee is composed of representatives of the National Standards 
Bodies in Partner States, together with the representatives from the private sectors and consumer 
organizations. Draft East African Standards are circulated to stakeholders t hrough the National Standards 
Bodies in the Partner States. The comments received are discussed and incorporated before finalization of 
standards, in accordance with the procedures of the Community.  
 
Article 15(1) of the EAC SQMT Act, 2006 provides that “W ithin six months of the declaration of an East African 
Standard, the Partner States shall adopt, without deviation from the approved text of the standard, the East 
African Standard as a national standard and withdraw any existing national standard with sim ilar scope and 
purpose”.  
 
East African Standards are subject to review, to keep pace with technological advances. Users of the East 
African Standards are therefore expected to ensure that they always have the latest versions of the standards 
they are imple menting.
