The world’s top condom producer, Malaysia’s Karex Bhd, plans to raise prices by 20% to 30% and possibly further if supply chain disruptions drag on due to the Iran war, its chief executive has said.

Karex is also seeing a surge in condom demand as rising freight costs and shipping delays have left many of its customers with lower stockpiles than usual, CEO Goh Miah Kiat told Reuters in an interview on Tuesday.

“The situation is definitely very fragile, prices are expensive … We have no choice but to transfer the costs right now to the customers,” Goh said.

Karex produces more than 5 billion condoms annually and is a supplier to leading brands like Durex and Trojan, as well as national health systems such as the UK’s NHS and global aid programmes run by the United Nations.
