You will discover numerous other distinct kinds of industries, and frequently organized into unique classes or sectors by a number of industrial classifications. Business classification systems applied by the government typically divide industry into 3 sectors: agriculture, manufacturing, and services. The key sector of industry is agriculture, mining and raw material extraction. The secondary sector of industry is manufacturing. The tertiary sector of market is service production. Occasionally, one talks about a quaternary sector of business, consisting of intellectual services which include research and improvement (R&D).
Industries can also be identified by product: chemical sector, fine chemical compounds business, petroleum industry, automotive market, packaging industry, hospitality business, food industry, fish industry, software market, paper business, furniture industry, testing equipment sector, safety equipment market, entertainment industry, etc.
Fine Chemical compounds Industry:
In chemistry, a chemical substance is a material with a specific chemical composition.
A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Some typical chemical substances are diamond, gold, salt (sodium chloride) and sugar (sucrose). Generally, chemical substances exist as a solid, liquid, gas, or plasma and may change between these phases of matter with changes in temperature or pressure. Chemical reactions convert one chemical substance into another. Forms of energy, which include light and heat, are not considered to be matter, and thus they are not "substances" in this regard.
Fine chemical substances are pure, single chemical substances that are commercially produced with chemical reactions into highly specialized applications. Fine chemical substances produced can be categorized into active pharmaceutical ingredients and their intermediates, biocides, and specialty chemicals for technical applications.
In herbal extract technology, a distinction is made between bulk chemical substances, which are produced in massive quantities by standardized reactions, and fine chemical compounds, which are custom-produced in smaller quantities for special uses. There is a very large number of fine chemical substances that are produced, and thus the chemistries of producing them need to be flexible. Owing to the small volume and often-changing chemistry, fine chemicals compounds production is more expensive, generates more waste and requires a higher study investment per kilogram. However, fine chemical substances are produced in industrial quantities unlike analysis chemicals, which are produced only in the laboratory.
