HS-6 · Subheading
280910
Diphosphorus pentoxide
Heading 2809 — Diphosphorus pentaoxide; phosphoric acid; polyphosphoric acids, whether or not chemically defined
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-6 280910 when importing or exporting diphosphorus pentoxide, a white crystalline solid often used in glass production and as a dehydrating agent. For example, a shipment of diphosphorus pentoxide in 25 kg bags would fall under this code.
This HS-6 line specifically covers diphosphorus pentoxide, distinguishing it from HS-6 280920, which pertains to phosphoric acid. While both are phosphorus oxides, diphosphorus pentoxide is primarily used for its dehydrating properties, whereas phosphoric acid is more commonly used in fertilizers and food processing.
When classifying your product, consider that diphosphorus pentoxide may also be referred to as phosphorus(V) oxide. It’s important to ensure that your product meets the specifications for this HS-6 code to avoid misclassification.
If you're dealing with polyphosphoric acids, you would refer to a different HS-6 line under the same heading. Understanding these distinctions can help streamline your import or export process.
