2809 — Diphosphorus pentaoxide; phosphoric acid; polyphosphoric acids, whether or not chemically defined
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-4 2809 when importing diphosphorus pentaoxide or phosphoric acid. For example, if you are bringing in a shipment of phosphoric acid for use in fertilizers, this is the code you need. It’s crucial to classify your goods correctly to avoid delays or penalties.
When deciding between HS-6 280910 and HS-6 280920, consider the specific chemical composition of your product. If your shipment consists solely of diphosphorus pentoxide, you should use 280910. However, if it includes phosphoric acid or polyphosphoric acids, opt for 280920 instead.
The distinction between these codes is important for regulatory compliance. For instance, HS-6 280910 is specifically for diphosphorus pentoxide, a compound used in various industrial applications, while HS-6 280920 covers phosphoric and polyphosphoric acids, which have broader uses in agriculture and food processing.
