I'm sorry, that's bizarre. Apparently, your definition of a "chemical weapon" is one that's composed of chemicals, and is used on people. By that definition, napalm is a chemical weapon, as is high explosive.
White phosphorus was used extensively in Vietnam and in other conflicts against people as an incindiary weapon. It has never been identified in any treaty as a "chemical weapon".
