HS-6 · Subheading
252230
Hydraulic lime; excluding calcium oxide and hydroxide of heading no. 2825
Heading 2522 — Quicklime, slaked lime and hydraulic lime; other than calcium oxide and hydroxide of heading no. 2825
Chapter 25: Salt; sulphur; earths and stone
Plain-language overview
Use HS-6 252230 when importing or exporting hydraulic lime, which is a key construction material. For example, a shipment of hydraulic lime in bulk for use in mortar or plaster would fall under this code.
This code specifically covers hydraulic lime, which differs from quicklime and slaked lime found in nearby classifications. Unlike quicklime, which is produced by heating limestone, hydraulic lime can set under water, making it suitable for various construction applications.
If you're dealing with products like calcium oxide or hydroxide, those would be classified under HS-6 2825. It's important to distinguish between these materials, as they have different chemical properties and uses in construction.
Hydraulic lime is often used in building restoration and masonry work due to its ability to harden in wet conditions. This makes it ideal for projects where moisture is a concern, such as in coastal areas.
