In January, two tonnes of ivory worth Sh86 million in transit from Tanzania to Indonesia were seized in Mombasa, a regional trade hub.
Ivory trade is banned under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
The illegal ivory trade, estimated to be worth more than Sh600 billion a year, is mostly fuelled by demand in Asia and the Middle East, where elephant tusks and rhinoceros horns are used in traditional medicine and to make ornaments.
