HS-6 · Subheading
283524
Phosphates; of potassium, whether or not chemically defined
Heading 2835 — Phosphinates (hypophosphites), phosphonates (phosphites), and phosphates; and polyphosphates, whether or not chemically defined
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-6 283524 when importing or exporting potassium phosphates, such as dipotassium hydrogen phosphate used in fertilizers. This code specifically covers phosphates derived from potassium, which are crucial in agricultural applications.
This HS-6 line is distinct from HS-6 283523, which pertains to sodium phosphates. While both are phosphates, the key difference lies in their base element—potassium versus sodium—which affects their applications in soil nutrition and plant growth.
Potassium phosphates can appear in various forms, including granules or powders, and may be chemically defined or not. They are commonly used in food processing, agriculture, and as buffering agents in pharmaceuticals.
When classifying potassium phosphates, consider the specific chemical composition and intended use. This can help clarify whether you should use this HS-6 or a different one under the same heading.
