HS Code for Disodium phosphate

Disodium phosphate is classified under HS code 2835.22. This classification falls within Chapter 28, which covers inorganic chemicals. Heading 2835 is dedicated to phosphinates (hypophosphites), phosphonates (phosphites), and phosphates. The classification is highly specific to the chemical structure of the product. Disodium phosphate, also known as disodium hydrogen phosphate, is a sodium salt of phosphoric acid. According to the General Rules of Interpretation (GRI 1), the product is classified based on its chemical identity as a phosphate of sodium. Subheading 2835.22 specifically identifies phosphates of mono- or disodium. To remain in this classification, the product must be a separate chemically defined compound. If the disodium phosphate is mixed with other ingredients to create a specific functional preparation (like a food additive mix), it may be classified elsewhere, but the pure chemical form is strictly 2835.22.

Products Included

• Anhydrous disodium phosphate
• Disodium phosphate dihydrate
• Disodium phosphate heptahydrate
• Disodium phosphate dodecahydrate
• Food-grade disodium phosphate (pure)

Common Misclassification

Disodium phosphate is often confused with HS code 2835.24, which is for phosphates of potassium. Another common misclassification occurs with HS code 3103, which covers mineral or chemical phosphatic fertilizers. While disodium phosphate contains phosphorus, it is typically used in industrial or food applications rather than as a fertilizer. If it is part of a prepared detergent, it might be misclassified under 3402, but the pure chemical remains in 2835.22.

FAQ

What is the HS code for Disodium phosphate?

The HS code for disodium phosphate, as a separate chemically defined inorganic compound, is 2835.22.

Does the hydration state change the HS code?

No, whether the disodium phosphate is anhydrous or hydrated (e.g., dihydrate or dodecahydrate), it remains classified under HS code 2835.22 as long as it is not mixed with other substances.
