Hit by slowdown and reduction of duty on petroleum goods, customs and central excise collection declined during September.
While the customs duty collection realisation during the month declined by 10.9 per cent to Rs 10,126 crore (Rs 101.26 billion), central excise realisation dropped marginally by 0.3 per cent to Rs 11,417 crore (Rs 114.17 billion), Finance Ministry data show.
The only saving grace in indirect tax collection during the month was 29.6 per cent rise in service tax realisation.
The service tax collection during September was Rs 6,967 crore (Rs 69.67 billion) as against Rs 5,374 crore (Rs 53.74 billion) in the same period last fiscal.

The government in June slashed customs and excise duties on crude oil and products sacrificing Rs 49,000 crore (Rs 490 billion) of annual revenue.
The move was aimed at giving some relief to people from hike in prices of diesel, cooking gas and kerosene.
As far as first six months of the current fiscal (April-September) is concerned, the total indirect tax collection works out to be Rs 1.69 lakh crore (Rs 1.69 trillion), up 20.8 per cent from what was mopped up in corresponding period last fiscal.
