The Comptroller of the command, Mr Charles Edike, said in a statement that the revenue generated in January dropped from the N20.2 billion realised in December, 2013.
Edike said that revenue collected for the Federation Account was N9.3 billion, while N9.5 billion was collected for the non-Federation Account in January.
He said that the revenue was realised from the payment of duty on imported sugar, wheat grain, wheat flour, levy on iron, seven per cent port levy and other taxes.
Edike said that the 20 per cent duty collected on rice importation during the period was N30.9 million against N1 million generated from the source in December, 2013.
He said N235 million was generated from the Negotiable Duty Credit Certificate, NDCC, during the period, while N10 million was realised from the seven per cent charge on NDCC.
NAN reports that the NDCC is a payment document for the importation of raw materials.
