Indian containers meant for Europe have piled up at India’s Jawaharlal Nehru Port (JNPT) and Tuticorin due to Maersk and CMA CGM curtailing calls of their vessels at the ports.

There are about 30,000 boxes lying in the arc between JNPT on the west coast and Tuticorin on the east, according to the Western India Shippers’ Association.

The backlog could take up three weeks to clear, the group said.

The shortage of slots in Europe-bound containers vessels has increased the rates between India and Europe from 900-$1,000 to 2,800-$3,000 per teu in recent months.
