About HS Code 252230

This HS code pertains to hydraulic lime, a unique type of lime that sets and hardens in the presence of water, similar to cement, due to its clay content. Unlike pure slaked lime, it offers hydraulic properties, making it particularly valuable in construction, especially for historical building restoration, sustainable construction, and specialized masonry applications where breathability and flexibility are desired. International trade in hydraulic lime is often driven by demand from conservation projects, eco-friendly building initiatives, and regions with specific architectural heritage. Exporters are typically countries with natural deposits of argillaceous limestone suitable for producing hydraulic lime, such as France and the UK. Importers include nations with active restoration sectors or a growing market for natural building materials. Its trade volume is smaller than that of quicklime or slaked lime but represents a niche, high-value market.
