The Kenya Revenue Authority introduced new generation excise stamps for tobacco products, wines and spirituous beverages with effect from April 1, 2013. KRA said in a public noticed published last month that the stamps are expected to enhance excise duty compliance as well as increase sales of duty paid goods.
The stamps have various security features including colour-shifting ink visible to the naked eye, and a hidden security feature that is revealed when a validator is used.
The notice that was published last month in various daily newspapers can be downloaded from here: KRA Notice on Tax Stamps (22 Apr 13)
Products affixed with the new tax stamps have already appeared in the market.
