For example: qualities vary from industrial and technical to high purity and fit for human consumption. Packages vary from pails, paper bags, fiber drums, super sacks, to bulk. Grades can be lump, granular, powder, slurry, or micron sized. Many goods are sold with lot numbers traceable to the original production and meeting ISO 9000 standards and with Certificates of Analysis conforming to USP or Bacteria free.
