HS-6 · Subheading
283539
Polyphosphates; other than sodium triphosphate (sodium tripolyphosphate), 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 283539 when importing or exporting polyphosphates that are not sodium triphosphate. This includes products like ammonium polyphosphate used in fertilizers, which are essential for agricultural applications.
This code specifically covers polyphosphates other than sodium triphosphate, distinguishing it from HS-6 283540, which includes sodium triphosphate itself. Understanding this difference is crucial for compliance and accurate tariff classification.
Polyphosphates can be used in various applications, including food processing as emulsifiers or in detergents. If your product is a complex polyphosphate blend, ensure it fits the criteria outlined for this HS-6 line.
When determining if this code applies, consider the chemical composition and intended use of your product. If it contains a mix of phosphates and polyphosphates, you may need to consult with a customs broker for precise classification.
