The International Bunker Industry Association (IBIA) has called for a consistent testing method for sulphur levels in bunker fuels that allow a margin of error in an attempt to avoid thorny legal issues when IMO 2020 rules come into force.

While the IMO has required vessels to switch to 0.5%-sulphur fuels from next January, IBIA, which represents bunker players, suggests there remains a lack of uniform sulphur verification methods.
