281520
Potassium hydroxide (caustic potash)
Heading 2815 — Sodium hydroxide (caustic soda); potassium hydroxide (caustic potash) peroxides of sodium or potassium
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-6 281520 when importing or exporting potassium hydroxide, commonly known as caustic potash. This chemical is often found in industrial applications, such as fertilizers or cleaning agents.
Potassium hydroxide is distinct from sodium hydroxide, which falls under HS-6 281511. While both are strong bases used in similar applications, their chemical properties and specific uses can differ significantly.
This HS-6 line specifically covers potassium hydroxide in solid form, typically in the form of pellets or flakes. It is crucial for manufacturers in sectors like agriculture, where it is used to produce potassium-based fertilizers.
When considering this code, be aware of its applications in food processing and soap manufacturing, as well as its role in various chemical syntheses. Ensure that your product meets the specifications for classification under this HS-6.
