Inorganic chemicals

CompoundList groups inorganic substances by their anion or element, the same logic that chapter 28 of the Harmonized System follows. Acids, hydroxides, halides, sulfates, nitrates, phosphates, carbonates, oxides, elements, rare earth compounds, industrial gases and other salts each have their own page, with HS codes and trade data linked from every substance.

For inorganic chemicals the grade often matters more than the molecule. The same salt can be sold as technical, fertilizer, feed, food, pharmaceutical, reagent, battery or electronic grade, and the price and documents differ for each. State the assay, the form (flakes, pearls, powder, granules, solution and its concentration), heavy metal and chloride limits, particle size and packaging in your request. Hydrated and anhydrous forms have different CAS numbers and active contents, so confirm which one you need. Ask for a certificate of analysis and a safety data sheet, and check transport rules, since many acids, alkalis and oxidisers are dangerous goods.
