283529

Phosphates; (other than of mono- or disodium, other than of potassium or of calcium hydrogenorthophosphate (dicalcium phosphate) and excluding other phosphates of calcium), whether or not chemically defined

Heading 2835Phosphinates (hypophosphites), phosphonates (phosphites), and phosphates; and polyphosphates, whether or not chemically defined

Chapter 28: Inorganic chemicals

Plain-language overview

Use HS-6 283529 when importing or exporting phosphates that are not mono- or disodium, potassium, or calcium hydrogenorthophosphate. An example would be a shipment of ammonium phosphate used in fertilizers.

This code specifically covers phosphates that do not fall under the more common categories, such as dicalcium phosphate. If you're dealing with phosphates like ammonium phosphate or other complex formulations, this is the right classification.

In contrast, HS-6 283510 includes mono- or disodium phosphates, which are often used in food applications. If your product is a simple phosphate salt, you may need to consider that code instead.

When classifying, be mindful of the chemical composition of your product. If it contains any calcium or potassium phosphates, you should look at other HS-6 lines to ensure proper classification.
