Plain-language overview
Use HS-6 252100 when importing or exporting limestone flux or other calcareous stones specifically used in lime or cement production. For example, if you're shipping crushed limestone intended for a cement plant, this is the correct code.
This code applies to limestone flux, which is essential in the manufacturing process of lime and cement. It differs from HS-6 2522, which covers other types of stone not specifically used for these industries.
Limestone flux includes materials like calcitic limestone and dolomitic limestone that are processed to remove impurities. This is crucial for ensuring the quality of lime and cement products.
When classifying your products, consider whether they are intended for lime or cement production. If they are used for construction aggregate instead, you may need to look at other HS codes.
