North Charleston, South Carolina-based Ingevity announced on Monday a general price increase effective July 1 – varying by market and region – for its pine chemical-based products, including tall oil fatty acid and distilled tall oil, which it supplies to the lubricant and metalworking fluid markets. The company cited continued supply and demand imbalance, which is expected to be exacerbated by the upcoming closure of a U.S. paper mill previously supplying feedstock to Ingevity, along with competitive pressures on feedstock related to the impact of biofuel regulations.
