Carbonyl Fluoride
Carbonyl fluoride (COF2) is a colorless, highly toxic gas used in fluorocarbon production and as a fluorinating agent. As a halide oxide of carbon, it is explicitly included in Chapter 28 by Note 2(a). It is a chemically defined compound, classifiable under this tariff item as an 'other' halide oxide of non-metals.
