The County Government of Nairobi, through its Legal Metrology Department, has notified traders of the annual verification and certification of all weighing and measuring instruments within the county.
“Pursuant to the provisions of CAP 513 Section 27 (1) of the Weights and Measures Act (Revised Edition 2012) (1989), the Nairobi City County Government hereby notifies the business community and traders in Nairobi that the annual verification and certification of Weighing and Measuring Instruments will be undertaken,” the notice read.
According to the Nairobi County notice, the exercise requires all traders to present their weighing and measuring instruments at designated stamping stations across Nairobi County.
“All types of weighing and measuring instruments within the County should be presented at the designated stamping stations for verification and issuance of a Verification Certificate upon passing the inspection and payment of the stipulated fees,” the notice noted.
The verification process aims to ensure that all instruments used in trade are accurate and comply with legal standards.
As per the notice, traders are expected to have both movable and fixed instruments available for inspection. Instruments that weigh 500 grams or more may be tested using district counter-check measures, while fixed instruments will be verified in their positions.
If the inspector finds the instruments accurate and compliant with the Act, they will be stamped or marked using plugs, leads, seals, paint, or other adequate methods to indicate certification.
The Nairobi County Government emphasised that this annual stamping is intended to eliminate inaccurate measurements, a recurring challenge in the county’s marketplaces.
“If an inspector is satisfied that a weight, measure, or instrument brought to them is accurate and otherwise in accordance with the Act, they shall stamp such weight, measure, or instrument,” the notice stated.
The verification exercise is scheduled to run from February to May 2026, with stamping stations set up in all sub-counties in Nairobi County.
