According to the 2012 Chemical Economics Handbook report on sulfur, the prices for elemental sulfur can fluctuate between $50 and $800 per ton. Drastic per-ton price fluctuations in sulfur are unusual.
These prices for sulfur are only when massive amounts of the raw material are being purchased by the ton. People who need smaller amounts of sulfur for at-home uses pay the retail price. According to the website for Duda Energy Biodiesel, a 10-pound bag packaged for retail costs roughly $11.50 as of July 2014. Regardless of price fluctuations, sulfur has quite a bit of worth because it is necessary for many industrial purposes, including the manufacturing of fertilizer.
