HS Code for Calcium nitrate

Calcium nitrate is classified under HS code 2834.29, which pertains to nitrates other than those of potassium. This classification is situated within Chapter 28, covering inorganic chemicals. Heading 2834 specifically includes nitrites and nitrates. The subheading 2834.21 is reserved for potassium nitrate, leaving 2834.29 as the category for all other inorganic nitrates, including calcium nitrate (Ca(NO3)2). However, classification of calcium nitrate is highly dependent on its purity and intended use. Under Note 2 to Chapter 31, certain mineral or chemical fertilizers are classified in Chapter 31 even if they are chemically pure. Pure calcium nitrate or calcium nitrate tetrahydrate used for industrial purposes (such as concrete additives or wastewater treatment) is correctly placed in 2834.29. If the product is a double salt or a mixture of calcium nitrate and ammonium nitrate intended for use as fertilizer, it must be moved to Chapter 31. For the pure chemical compound, 2834.29 remains the standard classification for international trade.

Products Included

• Anhydrous calcium nitrate
• Calcium nitrate tetrahydrate
• Industrial grade calcium nitrate for concrete setting accelerators
• Calcium nitrate used in latex dipping processes

Common Misclassification

Calcium nitrate is frequently misclassified under HS code 3102.60. Code 3102.60 is specifically for double salts and mixtures of calcium nitrate and ammonium nitrate used as fertilizers. If the product is a pure chemical salt, it belongs in 2834.29. Another error is confusing it with potassium nitrate (2834.21) or magnesium nitrate (2834.29), though the latter shares the same subheading but is a different chemical entity.

FAQ

What is the HS code for pure calcium nitrate?

The HS code for pure, chemically defined calcium nitrate is 2834.29.

When should I use HS code 3102.60 instead?

You should use 3102.60 if the product is a mixture of calcium nitrate and ammonium nitrate, or a double salt of these compounds, typically used for agricultural fertilization.
