The Government says this will help maintain spending on important wildlife projects.
Under the Convention on International Trade in Endangered Species (CITES), licences are required for the trade in listed species.
Conservation organisations such as botanic gardens and zoos will be able to apply to Defra for exemption from fees. Businesses including specialist nurseries and plant brokers will have to pay from 6 April.
Defra will be issuing guidance to companies on how to submit effective applications and they will be allowed to buy a licence covering multiple CITES specimens, reducing the cost per item.
Wildlife minister Huw Irranca-Davies said: "Endangered species are extremely valuable to the world's natural environment and this system is being introduced after consultation with everyone involved. Conservation projects are vital to helping us protect our wildlife for future generations and I have made sure important projects will not be charged for the licences."
