“Quicklime, slaked lime and hydraulic lime; other than calcium oxide and hydroxide of heading no. 2825” divides three ways under heading 2522 — 252210, 252220 and 252230. Each carries its own customs description, and the exact wording below is what a classification has to match.

What HS code 2522 covers
Importers and exporters use heading 2522 for three kinds of lime. In some countries the same heading is written as HSN code 2522. The first four digits are the same.
Lime is made from limestone. It is used in building, steel making, water treatment and farming. People also search for it as burnt lime or hydrated lime. Those are common trade names for the products below.
Customs officers look at what the goods are, not what the seller calls them. If you are unsure, test your product description in the HS code classifier before you file.
Quicklime, slaked lime and hydraulic lime: codes 252210, 252220 and 252230
Each code covers one type of lime. Here is what sets them apart.
- 252210 is quicklime, often called burnt lime. It is lime that has been heated and has not yet been mixed with water.
- 252220 is slaked lime, often sold as hydrated lime.
- 252230 is hydraulic lime. It is lime that can set and harden even when water is present.
How to classify lime: 2522 vs 2825, 2521 and 2523
Several nearby headings sound alike, so mistakes are common. Use the points below to tell them apart.
Heading 2522 leaves out calcium oxide and calcium hydroxide that belong to heading 2825. Heading 2825 is in the chemicals part of the tariff. So a product sold as a chemical grade of calcium oxide or calcium hydroxide may not belong under 2522. Check the exact wording of the code before you decide.
Raw limestone is not lime. Lime is made from that stone, and 2522 starts after that step.
Cement is also a different product. Portland cement, aluminous cement, slag cement and similar hydraulic cements belong to heading 2523. Hydraulic lime and hydraulic cement both set with water, but they are listed under different headings. Gypsum and plasters sit in heading 2520, and dolomite sits in heading 2518.
Customs rules differ by country, so always confirm the final code with your national tariff.
