Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-6 283531 when importing or exporting sodium triphosphate, a common food additive and cleaning agent. For example, shipments of sodium tripolyphosphate in bulk for use in detergents fall under this code.
This code specifically covers polyphosphates like sodium triphosphate, which is distinct from other phosphates that may not have the same chemical structure or applications. For instance, HS-6 283530 includes other forms of phosphonates that are not specifically sodium triphosphate.
When considering this HS-6, note that sodium triphosphate is often used in food processing as a preservative or emulsifier, while other polyphosphates may be used in industrial applications, such as water treatment.
If you're dealing with sodium triphosphate, ensure your product specifications match this classification, as using the wrong code could lead to customs delays or fines.
