Manufacturers saw a second consecutive month of declines in the cost of inputs at the end of August.
For the period, the Producer Price Index fell by 0.6 per cent.
The decline was due mainly to a 2.8 per cent fall in the cost of Refined Petroleum Products.
The downward trend was, however, tempered by a 0.1 per cent increase in the index for inputs in the Manufacture of Food Products category.
The cost of goods to manufacturers moved up by 19.6 per cent for the year ended August.
