Price is driven by base stock type, additive package, quality grade, and certification requirements. Mineral oil pricing tracks refining feedstock costs and regional supply. Ester fluids usually cost more due to raw material and processing, but may reduce fire mitigation or environmental costs. Packaging, transport, and hazardous or special handling requirements affect delivered cost. For utilities, large volume contracts, supplier qualification, and testing documentation can influence price. Local taxes, import duties, and currency exchange also create regional differences, especially where oil must be shipped long distances.
