HS chapter 25: Salt; sulphur; earths and stone
Section V — Mineral products
Goods classified under HS-25 include salt, various minerals, and construction materials like gypsum and cement. For example, if you're importing table salt for food processing, you'll use 2501. Understanding the specific HS-4 classification is crucial for accurate tariff application and compliance.
To determine the appropriate HS-4 code, start with the general product category. If your product is salt, check 2501 for table salt or 2502 for iron pyrites. If it's a mineral like gypsum, navigate to 2520. Each HS-4 heading provides a clearer definition, helping you avoid confusion with similar products.
When drilling down to HS-6, pay attention to the specific characteristics of your product, such as purity, form, and end-use. For instance, if you're dealing with cement, you might choose 2523 for Portland cement, which is essential for construction. Always refer to the notes and specific descriptions to ensure compliance with national regulations.

Questions & answers
For orientation only—the binding text is your national tariff and the WCO nomenclature your country uses.
- What is the HS code for table salt?
- The HS code for table salt is **2501**, which includes pure sodium chloride.
- How do I classify gypsum for import?
- Gypsum is classified under **2520**. Ensure it meets the specifications for plasters and calcium sulphate.
- What is the difference between HS-2501 and HS-2502?
- HS-2501 covers table salt, while HS-2502 refers to unroasted iron pyrites, which are used in industrial applications.
- How do I find the right HS-6 code for minerals?
- To find the correct HS-6 code, refer to the specific characteristics of your mineral product, such as its form and intended use.
- What are the requirements for importing cement?
- When importing cement, use code **2523** for Portland cement and ensure compliance with local regulations on construction materials.
