Chemical product classification fine chemicals

A classification by chemical type is given ia Table 1. It does not attempt to be either rigorous or complete. Clearly, some materials could appear ia more than one of these classifications, eg, polyethylene waxes [9002-88 ] can be classified ia both synthetic waxes and polyolefins, and fiuorosihcones ia sihcones and fiuoropolymers. The broad classes of release materials available are given ia the chemical class column, the principal types ia the chemical subdivision column, and one or two important selections ia the specific examples column. Many commercial products are difficult to place ia any classification scheme. Some are of proprietary composition and many are mixtures. For example, metallic soaps are often used ia combination with hydrocarbon waxes to produce finely dispersed suspensions. Many products also contain formulating aids such as solvents, emulsifiers, and biocides.

A key product classification scheme in the chemical industry is the differentiation of specialty and commodity products. Kline (1976) provides a segmentation of the chemical industry into commodities, specialties and fine chemicals shown in fig. 28. 

The official trade and custom statistics are not broken down to fine chemicals. The US Bureau of the Census classification, for instance, uses the following main product categories organic chemicals, inorganic chemicals, plastics, fertilizers, pharmaceuticals, cosmetics, dyes colorants, and other. ... 

There are other methods of classifying the products of the CPI. Frequently combinations of classifications are used to give insights into various aspects of the industry. One of the more useful of these is a classification obtained by combining production volume and differentiation to yield the four product classifications shown in Table 5.6. This separation into commodity, pseudocommodity, fine, and specialty chemicals is particularly useful in examining differences in research and development, manufacturing methods, marketing, and finance for...

There are no universally accepted definitions of bulk, fine, and specialty chemicals, nor are these classifications based on any intrinsic properties. A substance that is currently viewed as a bulk chemical might well have been classified as a fine chemical at an earlier stage in its development. A useful working definition of a fine chemical is one with a price of more than 10 US dollars kg and a volume of less than 10000 tons per annum on a worldwide basis. We make no distinction between fine chemicals, that are often intermediates, and specialty chemicals such as pharmaceuticals, pesticides, and flavors and fragrances. The type of technology used to manufacture these products is dictated more by volume than by product application.
