Phosphinates (hypophosphites) and phosphonates (phosphites), 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 283510 when importing or exporting phosphinates (hypophosphites) and phosphonates (phosphites), which are used in various applications like fertilizers and flame retardants. For instance, a shipment of a phosphinate compound used as a plant nutrient falls under this code.
This code specifically addresses phosphinates and phosphonates that may or may not be chemically defined. In contrast, HS-6 283511 covers phosphates, which are different in chemical structure and application, often used in detergents and food additives.
When dealing with HS-6 283510, you are focusing on specific phosphorus-containing compounds that serve roles in agriculture and industrial processes. These substances can be found in formulations for herbicides and other agricultural chemicals.
Be cautious not to confuse this with HS-6 283519, which includes other phosphinates and phosphonates not specifically defined. Understanding the precise chemical nature of your product is crucial for correct classification.
