2510 — Natural calcium phosphates; natural aluminium calcium phosphates and phosphatic chalk
Chapter 25: Salt; sulphur; earths and stone
Plain-language overview
Use HS-4 2510 when importing natural calcium phosphates, such as unground or ground phosphatic chalk. For example, if you're bringing in unprocessed phosphatic chalk for agricultural use, this code applies directly to your shipment.
When deciding between HS-6 251010 and HS-6 251020, consider the state of the product. If your shipment consists of unground natural calcium phosphates, use 251010. However, if the product has been processed into a fine powder, opt for 251020.
Both subheadings under HS-4 2510 deal with similar materials but differ in processing. Ground phosphates are often used in fertilizers, while unground forms might be used in industrial applications or as animal feed supplements.
