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.

- What is hydraulic lime?
- Hydraulic lime is a type of lime that can set and harden in the presence of water, making it ideal for construction in damp conditions.
- How do I classify hydraulic lime for import?
- Use HS-6 code **252230** for hydraulic lime. Ensure that it is not calcium oxide or hydroxide, which fall under a different heading.
- Can hydraulic lime be used for plastering?
- Yes, hydraulic lime is commonly used in plastering, especially in areas where moisture resistance is important.
- What are the packaging options for hydraulic lime?
- Hydraulic lime can be packaged in bulk or in bags, typically ranging from 25 kg to 1 ton, depending on the shipment size.
- Is hydraulic lime suitable for historic building restoration?
- Yes, hydraulic lime is often preferred for historic restoration due to its compatibility with traditional materials and its ability to allow buildings to breathe.
- What is the difference between hydraulic lime and quicklime?
- Hydraulic lime sets in water and is used for wet applications, while quicklime is produced by heating limestone and requires water to slake before use.
- What types of projects use hydraulic lime?
- Hydraulic lime is used in various construction projects, including masonry, plastering, and civil engineering works, especially in moisture-prone areas.
- What should I consider when importing hydraulic lime?
- Check for proper classification, packaging standards, and any specific regulations regarding the import of construction materials in your country.
