About HS Code 252220
This HS code covers slaked lime, also known as calcium hydroxide (Ca(OH)2), which is produced by adding water to quicklime. It's a versatile industrial chemical widely used across various sectors. In international trade, it's primarily imported by countries with robust construction, environmental, and agricultural industries that may lack sufficient domestic production capacity. Exporters are typically nations with abundant limestone reserves and established processing facilities. Key applications include soil stabilization in construction, water and wastewater treatment (pH adjustment, flocculation), flue gas desulfurization in power plants, and as a component in mortars and plasters. Its trade is driven by industrial demand for its alkaline properties and its role in various chemical processes. Understanding its purity and specific grade is crucial for trade, as different applications require different specifications.
Products Under This Code
Hydrated lime powder, calcium hydroxide for water treatment, agricultural slaked lime, construction-grade slaked lime, industrial calcium hydroxide, food-grade slaked lime, lime putty
Real World Examples
Carmeuse hydrated lime, Graymont hydrated lime, Lhoist hydrated lime, Mississippi Lime hydrated lime
Common Misclassification
This code is specifically for slaked lime (calcium hydroxide) and should not be confused with 252210 (quicklime/calcium oxide) or 282590 (other inorganic bases), as 2825 specifically excludes calcium hydroxide of this chapter.
Products Classified Under 2522.20
Industry
This code belongs to the Minerals & Fuels industry.
Trade Overview
China, USA, and India are major producers and consumers, with significant trade occurring regionally and globally for specific industrial needs.
