Liner operator Zim is to pass on an Israel war risk surcharge to customers following a massive increase in insurance premium for ships trading to the country’s ports.

Zim said it will pass on the additional war risk premium charges “at cost”. Additional fees range from $50 per teu to $100 per teu, depending on the service.

Zim said war risk underwriters had told it that insurance rates could be changed every 24 hours depending on the country’s changing risk profile.
