HS Code for Slaked lime

Slaked lime, also known as hydrated lime or calcium hydroxide, is classified under HS code 2522.20. This classification is part of Heading 2522, which encompasses quicklime, slaked lime, and hydraulic lime obtained by the calcination of limestone. Slaked lime is specifically produced by the hydration of quicklime (calcium oxide). The classification under Chapter 25 is appropriate for industrial or commercial grade slaked lime used in construction, agriculture, or water treatment. It is important to distinguish this from chemically pure calcium hydroxide, which is classified in Chapter 28. The presence of impurities typical of the mineral source and the standard industrial production process keeps this product within the scope of Chapter 25, as it is considered a mineral product rather than a separate chemically defined compound.

Products Included

• Hydrated lime
• Commercial calcium hydroxide
• Builders' slaked lime

• Pickling lime (industrial grade)

Common Misclassification

Slaked lime is frequently misclassified under 2825.90, which is the code for chemically pure calcium hydroxide. It is also often confused with 2522.10, which is the code for quicklime (calcium oxide). Another error involves 2522.30, which is reserved for hydraulic lime, a product that sets under water.
