HS-6 · Subheading
283522
Phosphates; of mono- or disodium, 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 283522 when importing or exporting mono- or disodium phosphates, such as disodium hydrogen phosphate used in food processing or as a buffering agent. This code specifically applies to phosphates that may be chemically defined or not.
This HS-6 line is distinct from HS-6 283521, which covers di- or trisodium phosphates. While both belong to the same heading, the specific chemical structure and sodium content differentiate their classifications.
Phosphates classified under this code are often used in various applications, including fertilizers, food additives, and cleaning agents. They can be found in products like baking powder or as a nutrient source in agriculture.
When dealing with these phosphates, ensure you have the correct specifications on your invoices, as the chemical composition can affect tariff rates and regulatory requirements. Accurate classification is crucial for compliance.
