Calcium Nitrate Tetrahydrate

Calcium nitrate tetrahydrate (Ca(NO3)2·4H2O) is a chemically defined inorganic salt of calcium used primarily as a fertilizer component and in concrete setting accelerators. It falls under HTS 2834.29.10.00 as a nitrate of calcium, distinct from ammonium nitrate or other nitrates classified elsewhere. This white, hygroscopic crystalline powder provides essential nitrogen and calcium to plants.

Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

3102.60.00Lower: 25% vs 35%

If put up as a fertilizer for retail sale

Mixtures containing primarily calcium nitrate for agricultural use are classified in Chapter 31 as fertilizers, not pure chemical compounds.

3824.99Lower: 15% vs 35%

If mixed with other chemicals for industrial formulations

Blended preparations like concrete admixtures fall under chemical preparations rather than individual nitrates.

2835.29Lower: 14.1% vs 35%

If containing phosphides or other additives

Phosphinates, phosphonates, or complex salts shift to heading 2835 for specific inorganic acid salts.
