FMC Wyoming Corporation announced today that effective immediately, or as contract terms permit, it will increase the price of its Grade 260 "dense" soda ash sold to South African customers by $30 per metric ton and will increase the price of its Grade 100 "light" soda ash sold to South African customers by $50 per metric ton. This increase is necessary for FMC to recover increasing costs and continue to invest in its operations as the global demand for soda ash increases.
