- Chapter 28: Inorganic chemicals; organic or inorganic compounds of precious metals
- Heading 2835: Phosphinates (hypophosphites), phosphonates (phosphites) and phosphates; polyphosphates
- Subheading 2835.25: Calcium hydrogenorthophosphate
- Global validity: Used in over 200 countries for trade classification
- Key uses: Fertilizers, animal nutrition, food stabilizers
This classification ensures accurate tariff application worldwide.
Calcium Hydrogenorthophosphate Uses and HS Code Classification
Calcium hydrogenorthophosphate serves multiple industries under HS code 2835.25. Its high calcium and phosphorus content makes it versatile.
- Fertilizer additive: Boosts soil phosphorus levels for crop yield
- Animal feed supplement: Provides essential minerals for livestock
- Food industry: Acts as acidity regulator E341(ii)
- Pharmaceuticals: Used as tablet binder and filler
- Dentifrices: Mild abrasive in toothpaste formulations
Always match the end-use to avoid misclassification under HS 2835.
