 Introduction  
Despite the Rwandan growth trend, the wood sector has not been implemented as required to produce high 
quality wood products and vigorous competitive market. The quality of wooden furniture is highly affected by 
the quality of ti mber, standardized production chain, quality control mechanism and grading rules. The lack of 
aforesaid factors results into market dominated by poor quality wooden furniture, compromised safety and unfair 
competition at the market.  
The emerging market dyn amics show that consumer’s preferences have gradually shifted from furniture made 
by local timbers to the imported ones, which  is considered as a limiting factor to the development and growth of 
the wood economy in Rwanda.  
To ensure a positive trade balanc e in wood market there is a dire need to improve and ensure quality of domestic 
wood products.  
This Standard is one of the  series of standards  on furniture in Rwanda. The series currently consists of the 
following:  
DRS 413:2019 Furniture — Quality and grading of wooden furniture ( Under development )
