Drugs were not the only items seized. Animal skin, live reptiles and elephant tusks were part of the confiscated products.
Britain's minister for Immigration Compliance and the Courts, Chris Philp, said: "Organised crime groups drive the trade in endangered species and the movement of banned animal products is key to how they operate.
"This is why Border Force's specialist officers will continue their vital work at the border to prevent the importation and exportation of endangered animals and plants, as well as working alongside enforcement partners such as the National Wildlife Crime Unit, and police from across the UK to eradicate this ruthless and exploitative trade."
The operation was co-led by the World Customs Organisation and Interpol, Hindustan Times reports.
It also involved police, customs, environment, wildlife and forestry agencies from 111 countries.
Aside from the drugs, the contraband items impounded included 1.3 tonnes of ivory, more than one tonne of Pangolin scales, 1,400 live turtles and 1,800 reptiles.
