The previous government used a two-tier-pricing structure for LPG, with a disparity in prices for household gas and gas for industrial use.
The association's president Chitsanupong Rungrojngamcharoen said the government should revise its pricing strategy because the cost of gas had dropped sharply from US$900 (Bt11,400) per tonne to $330.
"The demand for gas rose due to higher oil prices, but now that both oil and gas prices are much lower, the government should not reduce the prices of gas used for industry and transportation," he said.
In addition, the Internal Trade Department yesterday called for LPG traders to cut their delivery fees for cooking gas from Bt15 to Bt10 per 15-kilogram tank in line with the reduced oil prices.
Vatchari Vimooktayon, deputy director-general of the Internal Trade Department, said the price of cooking gas in Bangkok should come down by January 15.
"Gas traders must reduce the price of 15kg LPG tanks by Bt5 due to the drop in oil prices," she said.
At present, a 15kg tank is sold for Bt290, including delivery.
