HTS US: 2510.XX.XXXX
Description
HTS Code 2510 covers natural calcium phosphates, natural aluminum calcium phosphates, and phosphatic chalk, which are mineral substances widely used in agriculture, animal nutrition, and various industrial processes. These materials are primarily valued for their phosphorus content and their role as phosphate fertilizers or feed supplements.
The products under this code are generally divided into two main physical states:
- Unground: Natural calcium phosphate minerals in their raw, coarse form, not subjected to grinding or milling.
- Ground: These are the same minerals but mechanically ground into a finer powder or granules to enhance solubility and ease of application.
Code Hierarchy
- Section IV: Animal or vegetable fats and oils and their cleavage products; prepared edible fats; animal or vegetable waxes (Chapters 25-27)
- Chapter 25: Salt; sulfur; earths and stone; plastering materials, lime and cement
- Heading 2510: Natural calcium phosphates, natural aluminum calcium phosphates and phosphatic chalk
- US HTS Code (10-digit):
2510.XX.XXXX– The last digits specify whether the product is ground or unground.
Detailed Breakdown of Subheadings
The heading 2510 is split into two primary six-digit and ten-digit subheadings reflecting the physical state of the phosphate mineral:
| HS/HTS Code | Description | Notes & Uses |
|---|---|---|
| 2510.10.00.00 | Unground natural calcium phosphates, natural aluminum calcium phosphates and phosphatic chalk | Raw mineral form, typically used in fertilizer production or as raw material for further processing. |
| 2510.20.00.00 | Ground natural calcium phosphates, natural aluminum calcium phosphates and phosphatic chalk | Finely milled phosphate powders, preferred for direct application in agriculture and as feed supplements due to enhanced bioavailability. |
What is NOT Classified Here?
Items excluded from this heading include:
- Manufactured or chemically treated phosphate fertilizers which fall under other specific fertilizer or chemical headings.
- Calcium phosphate compounds synthesized or purified industrially not in natural form.
- Other phosphate minerals not classified as natural calcium or aluminum calcium phosphates are covered under different codes.
Notes
- Uses in Agriculture: The natural calcium phosphates classified here serve as a primary phosphorus source in fertilizers to enhance soil fertility.
- Animal Feed: Ground forms are often incorporated into animal feed as phosphate supplements.
- Import Controls: Importers should verify compliance with environmental and safety standards applicable to mineral imports.
- Duty Rates: Duty rates vary by country of origin and physical form; consult the current USHTS for specifics.
