HTS US: 2835.XX.XXXX
Description
HTS Code 2835 encompasses a group of chemical compounds primarily based on phosphorus, including phosphinates (also known as hypophosphites), phosphonates (phosphites), orthophosphates, polyphosphates, and their salts. These substances have broad industrial applications, ranging from food additives and water treatment agents to components in detergents and fertilizers.
The heading covers both chemically defined compounds and polyphosphates regardless of their precise chemical structure or polymerization degree.

| 2835.22.00.00 | Of mono- or disodium | Phosphates where sodium is present as mono- or disodium salts, commonly used in water softening and detergents. |
| 2835.24.00.00 | Of potassium | Potassium salts of phosphates, typically used in fertilizers and food additives. |
| 2835.25.00.00 | Calcium hydrogenorthophosphate (“Dicalcium phosphate”) | Widely used as a dietary supplement and in animal feed; a calcium phosphate salt with mineral applications. |
| 2835.26.00.00 | Other phosphates of calcium | Other calcium phosphate compounds not classified as dicalcium phosphate, with applications in fertilizers and pharmaceuticals. |
| 2835.29 | Other: | Miscellaneous phosphate salts not specified elsewhere. |
| 2835.29.10.00 | Of aluminum | Aluminum phosphate compounds, often used in water treatment and as flame retardants. |

What is NOT Classified Here?
To ensure proper classification, the following are excluded from this heading:
- Organic phosphorus compounds such as organophosphates which fall under different chapters.
- Phosphorus compounds combined with metals or other elements forming complex inorganic compounds outside the specified categories.
- Phosphates in mixtures or formulations primarily classified under other headings due to their main components.
Notes
- Industrial Use: These compounds are vital in agriculture (fertilizers), food industry (additives), water treatment, and detergents manufacturing.
- Regulation: Importers should verify safety data sheets and comply with environmental and health regulations related to phosphorus compounds.
- Duty Rates: Vary by specific subheading and country of origin; consult the current USHTS for exact duty percentages and applicable trade agreements.
