Catom focuses on three primary activities in the downstream segment of the oil market: wholesale, sale through a network of trucks to end users in the business market on land (reselling), sale through own fleet of bunker boats and bunker stations to end users in the business market on water (reselling) and operation of petrol stations with shops (retail).

The major part of the turnover stems from wholesale and reselling.

In reselling, Catom is market leader in the Netherlands and its ambition is to achieve that position in the other two primary activities as well.

The 4 business units Catom PDM,OK Oliecentrale, OK Marine and OK Retail are interconnected and together they arestronger than the elements individually.
