Integer Research said its DEF Tracker price information service for the North American market now includes Montreal and Tampa in its monthly listing of prices for full and less-than-full truckload bulk DEF deliveries, totes and packaged products. The service now tracks pump prices on a state-by-state and province-by-province basis for Los Angeles, Houston, New York, Cincinnati, Chicago, Tampa, Toronto and Montreal.

The number of truck stops offering bulk DEF at the pump is increasing rapidly, according to Integer Research. In one recent four-week period, for example, 37 new locations were added.

Findings from the June issue of DEF Tracker include:

• The price of urea staged a sharp reversal in June and the cost of larger bulk deliveries (1,000-4,000 gal.) of DEF to fleets dropped. However, the effect on tote pricing was more diverse, with average prices moving by between -$0.01 and $0.03 per gal. in the U.S., and -$0.03 and $0.01 per gallon in Canada.

• The average U.S. DEF pump price increased by seven cents, to $2.88 per gal., in June. This trend means the price increased by $0.15 to $2.88 per gal. between February and June 2012 in response to raw material costs.

“The latest price data shows that DEF is strongly affected by volatile raw material costs,” said Christopher Goodfellow, market analyst at Integer Research. “A sharp upward movement in the price of urea between February and May resulted in increasing DEF prices during the first half of 2012.”
